Innovative radio technology keeps New Zealand’s Firefighters safe

We champion the advancement of communications within the emergency services, not only because it is an important part of their working day, but because they still have a long way to go before it is perfect. This news story comes from New Zealand and focuses on the fire service and is supplied by Motorola themselves.

Firefighters serving with New Zealand Fire Service will benefit from improved safety and communication while working in fire grounds through an innovative two-way radio solution.

The new solution from Motorola Solutions and Spark will enable the service’s 10,000 career and volunteer firefighters to stay connected to their colleagues in the field via reliable and robust voice communication.

Having attended around 73,000 incidents in the past year alone, New Zealand Fire Service needs the best tools for the job. The organisation will receive more than 4,500 new radios designed for use in the most severe fire ground environments.

A major feature of the solution is a cornerstone Motorola Solutions innovation, a remote speaker microphone that will be fully integrated within firefighters’ breathing apparatus. This will be combined with the radio’s convenient push-to-talk button, which enables firefighters to communicate easily and safely in the harshest conditions.

Paul Baxter, Chief Executive & National Commander of the New Zealand Fire Service, said,

“Communication is critical to safety on the incident ground, and much of that communication comes from the use of incident ground control (IGC) radio. That’s why we were so exacting in our requirements for these new radios.”

“The radios will help us to resolve radio interface issues with firefighters’ breathing apparatus while also delivering improved noise cancellation and battery life.”

By using a combination of single and multiband radios operating across both VHF and UHF bands, the solution aligns with the fire service’s vision of leading integrated fire and emergency services for a safer New Zealand.

“This radio solution enables us to move away from using a mix of models and frequencies and toward a nationally consistent standard that will make it easier to work with our emergency service partners,” Baxter said.

Murray Mitchell, Director ICT for the New Zealand Fire Service, said, “We wanted a solution that is safe, easy to use and doesn’t distract firefighters from their work during critical incidents.The design features incorporated in these new radios will help our firefighters work more safely and efficiently.”

Spark will provide in-country support including service management and a customer support desk.

Spark Digital CEO Tim Miles said: “Radios are life-saving tools for our emergency services, and great team communication can be the difference between a managed incident and a disaster. We are very proud to play a part in improving the on-ground experience for our Kiwi Fire Service heroes.”

Motorola Solutions Managing Director for New Zealand and Australia Steve Crutchfield said the solution drew on his company’s experience in providing tailored, mission-critical communications for public safety agencies all over the world.

“Firefighters depend on reliable and robust voice communications in emergency situations so they can concentrate on the job of protecting our communities and potentially saving lives,” Crutchfield said.

The radios are part of a five-year contract, giving New Zealand Fire Service operational and cost certainty throughout the life of the contract.

The contract also provides access provisions for related government agencies wanting to take advantage of the new radio technology.

A giant solar storm nearly triggered a nuclear war in 1967

We all know how important radio communications are and at a time before the internet and even digital communications, governments relied on RF communications that were susceptible to the suns solar storms, if you add that to the cold war nuclear tensions then we could all be living in holes now.

Cold War history is rife with close calls that nearly led to nuclear holocaust.

In September 1983, for example, sunlight reflecting off a patch of clouds fooled a Soviet missile-warning system into detecting the launch of five US intercontinental ballistic missiles that never were. A wary colonel in a bunker ignored the alarm on a 50/50 hunch.

Two months later, US forces staged “Able Archer 83” — a massive nuclear-strike drill on the doorstep of the USSR. Soviet commanders panicked at the show of force and nearly bathed America in thermonuclear energy. Once again, an act of human doubt saved the planet.

Now scientists have one more hair-raising event to add to the books: The “Great Storm” of May 1967.

“The storm made its initial mark with a colossal solar radio burst causing radio interference … and near-simultaneous disruptions of dayside radio communication,” a group of atmospheric scientists and military weather service personnel wrote in a new study, published August 9 in the journalSpace Weather.

Hours later, high frequency communications dropped out near US military installations in and near the Arctic — one of the closest places to station nuclear weapons and launch them at a Cold War-era Soviet Union.

“Such an intense, never-before-observed solar radio burst was interpreted as jamming,” the study authors wrote. “Cold War military commanders viewed full scale jamming of surveillance sensors as a potential act of war.”

A ‘Great Storm’

Earth’s magnetic field protects life on the planet by corralling the sun’s high-energy particles toward the planet’s polar regions.

If the sun happens to launch a cloud of solar particles directly toward Earth during a violent outburst, called a coronal mass ejection, it can trigger powerful geomagnetic storms.

This not only leads to beautiful auroras, but can also scramble wireless communications and disrupt radar systems.

While The Washington Post wrote up a story about the storm as “City Gets Rare Look at Northern Lights,” top US military commanders sounded the alarms in secret.

The Air Weather Service (AWS) — a relatively new branch of the Air Force — had warned military leadership about the possibility of a solar storm, but US commanders believed the Soviet forces were jamming NORAD systems designed to detect threatening planes and missiles.

As the Strategic Air Command warmed up the engines of bombers and taxied toward the runway, the decision to go airborne may have been kicked all the way up to the “highest levels of government,” possibly involving President Lyndon B. Johnson.

“Just in time, military space weather forecasters conveyed information about the solar storm’s potential to disrupt radar and radio communications,” according to a press release from the American Geophysical Union. “The planes remained on the ground and the U.S. avoided a potential nuclear weapon exchange with the Soviet Union.”

And this all happened at the peak of nuclear armament — when a record 31,255 nuclear weapons were deployed around the world. (Today there are roughly 7,200 nuclear armaments at hand.)

“Had it not been for the fact that we had invested very early on in solar and geomagnetic storm observations and forecasting, the impact [of the storm] likely would have been much greater,” study leader and UCAR atmospheric scientist Delores Knipp said in the release.

After the near miss, the researchers say the military learned to listen to its space weather forecasters, improve its abilities to see another looming “Great Storm,” and avert the first and perhaps final global nuclear exchange.

LeBlanc: Protect your hearing it is irreplaceable

This is an excellent story about how hearing protection is sometimes be essential, and when you’re on the shooting range it has to be vital. But it is important to get the right set of headphones that will protect your hearing sufficiently. Lessons can be learnt from this excellent case study.

There is no doubt that we all take our senses of sight, smell, and hearing for granted as long as we are strong and healthy and everything is working well. When we are young we tend to believe that we are indestructible and readily adopt the idea that “it will never happen to me.” Consequently, we can develop some bad habits and be a little loose when it comes to preventative measures for almost anything.

I know because that was my attitude at thirty years old when my eye doctor made a comment in passing that my eyes were perfect, but the chances are I would be needing reading glasses by the time I was 50. I scoffed, but you could almost have set your watch by it because by the time I was in my late 40’s my arms started to get shorter when it came to reading, tying on fishing lures and other things that required scrutiny up close. At 50 I was wearing reading glasses.

Growing up I never bothered too much about wearing ear protection. When I was plinking it was with a .22 rifle that only put out a little noise if you were the shooter so the thought of hearing protections seemed ludicrous. When hunting I do not know if I have ever heard my firearm discharge and beside that unless I was dove hunting I seldom shot too many shots anyway.

The change of heart came when I started shooting on an indoor range, while in the Air Force. I noticed after shooting a few rounds with my .22 caliber, Ruger Single Six that my ears would ring for a while afterward. One night a grizzled old Master Sargent suggested I wear ear protectors or take a chance of damaging my hearing. I took the recommendation to heart and have been wearing them ever since. The result has been that after many years of shooting .22’s, large caliber handguns, rifles and shotguns my hearing is still intact and working well.

Shooting is not the only activity that can cause hearing problem as any loud noise can damage your hearing. The intense vibration caused by loud noises can injure or destroy the hair cells inside the cochlea, so they no longer function to transmit nerve impulses to the brain. If that happens, you will experience hearing changes.

Hearing protection is needed anytime one is exposed to sounds above 80 decibels (dB). Normal human conversation runs about 30 to 35 dB. At its peak level, the sound of a 12-gauge shotgun is about 140 dB. 9mm runs around 159 dB and a .38 special with a six-inch barrel is about 156 dB, a .22 LR pistol with the same length barrel 140, an M-16 is about 154, a .45 ACP pistol is 155, and a .357 Magnum revolver is 164. All of them are around double the safe sound level. Just to be on the safe side I used to wear muff type hearing protectors and usually ear plugs also when on the range.

For range use today there is an array of muff style hearing protectors. The new style that I now use have not only hearing protection, but also hearing enhancement. The controls on each ear can be tuned to match your individual optimum hearing and increase the volume up to eight times normal. So when the range master gives a command or when you are speaking with a companion on the shooting line you can speak in a normal voice and hear them as well or better than without the power muffs. Yet when you shoot the sound activated compression circuit reduces the sound from the shot to a noise reduction rate of 24dB.

This is very important on a shooting range because I have missed range commands in the past from the range master simply because I could not hear them through my hearing protection.

The new muffs I use are from Walker’s but they offer many other styles in their Game Ear series. These are unlike the muff style protectors as the bulk of the unit fits behind your ear with an earpiece that fits inside your ear, the unit weighs less than one fourth of an ounce and can be used with or without glasses. These too can be fine-tuned to your specific hearing, allow you to turn the volume up to magnify sounds from five to seven times and still reduce the sound of the shots to a rating of 29dB.

The ability to custom tune the devise to your hearing as well as adjust the volume up on these models will enable the hunter to more readily pickup games sounds in the woods. Sounds like a squirrel jumping through the trees or when their belly slaps a tree when they jump from one to another. It will help the hunter pick up the minutest sound of a deer brushing by limbs or the whisper of them walking through leaves or disturbing a rock.

So now there is really no acceptable reason not to wear hearing protector and if you get a good set it may even enhance your chances of bagging some more game.

Where Is It Possible To Get a Great 2 Way Radio?

If you’re planning a family outing where you’ll camp for several days, or if you’re headed for an amusement packed backpacking expedition with friends, you might want to know where to buy 2 way radio communication systems. These gadgets are very small in size, and you can go with them wherever you want to as most of them weigh less than half a pound and you can hardly feel burdened by them as you hike.

Additionally, they come in very handy in regions where cell phones cannot dare venture. Some top quality walkie talkies can provide a huge array of features such as weather alerts as well as SOS signals. 2wayradionline has all kinds of two-way radios including the newest types that come with better-quality frequency options as well as radio ranges.

Types of two-way radios

Bearing in mind that there’s a myriad of two-way radio systems available in the market, arguably the most important question to ask yourself if you want to buy a walkie talkie is: what’s the best choice? However, this isn’t a very hard decision once you understand where and how you’ll use it. Firstly, you’ll need to pick either of the two main kinds of two-way radios, which are family or consumer walkie talkies and professional business walkie talkies.

Within both kinds, you would also want to decide whether a radio system with licensed or unlicensed band is most suitable for you. On the one hand, licensed radios come with powerful 5W frequency transmissions and a wider coverage range. However, you’ll have to be contented with a frequency fee. On the other hand, unlicensed band walkie talkies attract no fees, but they’re comparatively low in power plus a limited range that’s only suitable for casual users.

You would also want to decide between an analogue and a digital walkie talkie. Some businesses search for radio systems that can operate suitably in risky highly explosive environments. Radios with ATEX certification are highly recommended in such areas. You can find all these kinds of walkie talkies and more at 2wayradionline.co.uk

VHF or UHF walkie talkies?

An important consideration when looking to buy walkie talkie is keeping in mind that Ultra High Frequency (UHF) radios will be your best purchase in most cases. Essentially, a UHF radio can never send or receive communication to a Very High Frequency (VHF) radio. As such, if you have some walkie talkies and you’re only looking to add some more units to be used with what you already have, go for the same band.

VHF radios can provide more coverage with less power, but they only function well when there’s little interference between the sender and the receiver. UHF walkie talkies function best with most users since they have shorter waves and can penetrate or get around areas of interference such as hilly areas, thickly wooded areas, in buildings as well as in urban outdoor settings. If you’ll use your radios strictly indoors or if it’s a combination of indoors and outdoors, then UHF is the best choice. You can choose from some of the best VHF and UHF two-way radios at 2wayradionline .co.uk

5 Reasons The Secret Service Hate To Use a Radio Earpiece

When you think of the US Secret Service agents, the image that comes to mind is that of a person in dark sunglasses, black suit, and a coiled tube thing goes into his ear. The coiled tube thing is what the agents use to monitor and communicate what’s going around them, where dangers lurk and where they’re are needed. Unfortunately, the coiled tube thing tends to be very noticeable such that the bad guys will easily identify the secret service agents. Over the past couple of years, various earpiece companies have closely worked with the US secret service, and have supplied the agents with quality covert tactical earpieces. The covert tactical earpieces are much better than the traditional coiled tube earpieces because of a number of reasons. Some of the reasons include;

1. Discreetness/Covertness

Security professionals typically chose earpieces based on just how discrete/covert they want to be. The level of covertness or discreetness is usually determined by the type of earpiece, earpiece style, and also the color. As aforementioned, if you want to identify a secret service agent you can simply look for the guy with a coiled tube type of earpiece . Luckily for secret service agents, various earpiece companies now offer earpieces which allow the secret service agents to efficiently communicate in a more covert and discreet manner without anybody noticing. They allow for discreet communication between the agent and his or her team.

In-ear earpieces are typically more discreet because they’re worn inside of the the ear as compared to the over-the-ear earpieces which are worn outside of the ear. It is also wiser to opt for colourless earpieces as opposed to the coloured earpieces for extra covertness. You can also opt for the wireless earpieces; the wireless earpieces are usually preferred over the wired earpieces since it is hard to tell that somebody is actually wearing the wireless earpiece as compared to the coiled tube, wired earpieces. The wireless earpieces normally receive the signals wireless. One needs to have a separate microphone worn at the end of the sleeve, or even on a lapel. In order to send a message to the other(s), the wearer has to speak into that microphone, and the other(s) will receive the message via their wireless earpieces.

2. Comfort

You should obviously choose an earpiece which is comfortable to wear; Some of the crucial questions to ask prior to choosing an earpiece can include; how easy that earpiece is to not only wear, but also to remove, how easy is it to control and use the earpiece, and also whether the earpiece will be able to remain intact for as long as needed without falling off. One of the main reasons why most people dislike the coiled tube earpieces, is the lack of comfort. Most agents say that the coiled tube earpieces cause a lot of ear fatigue. Most of the secret service agents are usually connected to the radio 12 to 16 hours per day, and some agents will have the earpieces draped over their ears and hanging out, with the volume of their radio turned way up so they do not have to have to plug the coiled tube earpiece in their ears all day long. . Fortunately, the covert/discreet earpieces are very comfortable to wear. They use speakers which are smaller than the average ear canal; this means that there’s very little contact, thus are ideal for secret service agents who want to avoid the feeling of ear fatigue.

3. Sound quality

Secret service agents are dealt with protecting the President and as such, it is crucial to get everything right, including the message being sent to their earpiece. In case of a sensitive situation, it is even more crucial to get the message right or correctly. Listening to sounds which are being pushed up a coiled tube may leave a margin for error. The tactical earpieces have the speakers placed in the canal of the ear which means that the sound is basically created there, (approximately 7millimeters from the eardrum), and is worn in both of the ears. This allows the wearer to clearly listen to what’s being transmitted through the earpiece, meaning they will be more efficient in their work.

4. Volume

This is one of the main reasons why secret service agents dislike their coiled tube earpieces. Many of the secret service agents say that they usually feel like they are gradually incurring hearing loss especially in the ear which they plug the radio earpiece. Well, with the covert earpieces, the ear isn’t plugged so that the sound pressure can get released. And since it’s worn in both of the ears, and the speakers are located in the ear, the radio may be turned down, and you will have much better sound clarity. This allows agents to work more efficiently, and in addition, they will have no fear of incurring hearing loss.

5. Localization

The brain is typically wired to locate where sounds/noises originate from, or rather the brain is wired to localize. When you hear a sound from the right side, you will know it since it enters your right ear a little louder and a little quicker, and your brain registers that the sound came from the right direction. This means that a secret service agent, or anybody wearing the coiled tube type of earpiece in their right ear, might hear a similar sound a little louder in their left ear since their right ear is plugged. In sensitive situations, mistaking the location of the sound can be disastrous since it could leave time for bad guys to get away, attack, or complete their objective. The tactical earpieces are designed such that they help the secret service agents to accurately locate the actual place the sound is originating from.

Conclusion

The covert earpieces address all negative issues which anybody who wears or uses the coiled tube type of earpiece experiences. They’re comfortable, discreet, they use top notch, high end, high quality speakers which offer the best clarity, they help in reducing the risk of future hearing loss since one can reduce/adjust the radio volume, and they also allow wearers to accurately and quickly localize the direction a sound is coming from.

Farewell, Faithful Steed: Veteran Actor (and Sometime Fashion Icon) Patrick Macnee Dies, Aged 93

Patrick Macnee, the actor best known for his work on TVs The Avengers has passed away. He was 93 years old.

Macnee was born in London, England in 1922. His father trained racehorses and was noted for his keen fashion sense, whilst his mother was a niece of the Earl of Huntingdon (which may even have made Patrick a descendent of Robin Hood!). However, such privileged beginnings proved to be only deceptively comfortable for the young Macnee, who saw his father drink and gamble away the family fortune, before leaving the country for India, while Macnee lived with his mother and her Lesbian lover Uncle Evelyn Spottswood. The pair attempted to dress the young boy up as a girl, but settled for a kilt instead, which was how Macnee was dressed every day until he was eleven years old.

Spottswood paid for Macnees schooling, which included boarding school from the age of five, a preparatory school (where he acted alongside a young Christopher Lee in a production of Shakespeares Henry V) and ultimately a spell at Eton, where he joined the schools dramatic society. Eventually however, Macnee was quietly expelled from the school after he instigated a gambling ring and was then caught selling erotic photography and whiskey to his fellow pupils.

By this time though, he had already been bitten by the acting bug and so decided to pursue a career in the performing arts.

Before he could make his West End debut, the young actor was called up for National Service. It was 1942 and World War 2 was in full swing. He began his military career in the Navy as an ordinary seaman, before progressing to sub-lieutenant. Fortunately, a nasty bout of bronchitis caused Macnee to miss the D-Day landings, where the ship he was serving aboard was destroyed and the entire crew killed. He was ashamed of not being present at the battle for the rest of his life. Macnee was demobilized in 1946 with the final rank of lieutenant.

Patrick Macnee learned his craft via a number of small roles, appearing in The Life and Death of colonel Blimp in 1943 and portraying a Spear Carrier in Lawrence Oliviers 1948 production of Hamlet (alongside an uncredited Christopher Lee), amongst other assorted roles. However, as the years passed and his big break failed to arrive, Macnee became depressed and frustrated by his lack of progress.

Eventually, he decided to leave the United Kingdom for Canada, making the difficult decision to leave his wife and two children behind in the process. He arrived in Toronto with just £10 in his pocket. In Canada, Macnees eccentric Englishness made him a genuine novelty and his career began to pick up somewhat. He explored producing and, as an actor, appeared in over 30 televised plays, before finally hearing about a new television series in development called The Avengers.

In The Avengers, Macnee played the unflappable British secret agent John Steed from 1961 to 1969, before reprising the role for 1976 – 77s The New Avengers. Both the series and the character would become an iconic part of British popular culture, creating a legacy that endures to this day. The show made Macnee an international star and proved to be his finest hour as an actor.

The character of John Steed first appeared in The Avengers pilot episode Hot Snow (1961). Here, he was depicted as being an assistant to Dr. David Keel. When Ian Hendry, who had played Dr. Keel, quit the show later that year, Steed became the central character and was partnered with a series of crime fighting accomplices, namely Dr. Martin King (Jon Rollason), Venus Smith (Julie Stevens) and finally Cathy Gale (played by future Bond girl Honor Blackman).

As the series progressed, Macnee extensively re-designed Steeds wardrobe, furnishing his character with the now iconic look of bowler hat, Saville Row suit and gentlemans umbrella. Of course, these garments came to be tricked out with various spy gadgets as the series went on.

It was Steeds debonair, quintessentially British wardrobe that helped the show to become so successful both at home and overseas. In fact, the clothes were so iconic that in France The Avengers is known as Chapeau Melon et Bottes de Cuir – Bowler Hat and Leather Boots.

Macnee also decided early on that Steed should never carry a gun. In later interviews he stated that he was sick of firearms after experiencing “a war in which Id seen most of my friends blown to pieces”.

Besides, a pimped-out brolly is waaaaay cooler.

In 1965, Steed was paired with his most iconic partner (and best, but Im biased since she was my childhood crush) Mrs. Emma Peel. Portrayed by Diana Rigg, Mrs. Peel (designed to have man appeal – hence the name) was smart, self-assured and supremely confident. In a unique twist, Peel often acted as Steeds muscle, being by far the more physical of the two characters. Although he frequently rescued her from harm, their relationship was truly a partnership of equals, making Mrs. Peel, secret agent, martial artist and chemistry genius, a genuine pioneer among female heroines. Macnee was always proud of the strong, positive female characters that were so prominently featured in The Avengers.

Rigg left the series in 1968 and promptly followed her predecessor into the James Bond franchise, while Macnee was partnered with Linda Thorsons Tara King until the series demise a year later in 1969.

ITV revived the Avengers concept in 1976 and Macnee starred alongside Joanna Lumley (Purdy) and Gareth Hunt (Gambit). The show ran for two series, but, despite a positive reception, was scrapped in 1977 due to financial problems.

Away from The Avengers, Macnee appeared in the James Bond film A View to a Kill (1985) and the classic Rock n Roll mocumentary This Is Spinal Tap (1984), where he portrayed Sir Dennis Eton-Hogg, the somewhat sanctimonious president of Taps record company. He also played Dr. George Waggner in 1981s cult favourite The Howling.

In 1998, Hollywood made a disastrous attempt to revive The Avengers. The movie starred Ralph Fiennes, Uma Thurman and Sean Connery and Patrick leant his support in the form of a voice cameo. However, without the twinkle, wit and class of the original John Steed, the idea was doomed to failure.

Finding himself in the enviable position of being a pop culture icon, Macnee was asked to appear in music videos for The Pretenders and Oasis amongst others. He also contributed vocals to a novelty single Kinky Boots with Honor Blackman that was issued three times, the first in 1964, the second in 1983 and the third in 1990, where it eventually became a top 3 hit.

As a television actor, Macnee appeared in such memorable shows as The Twilight Zone, Rawhide, Colombo, Frasier, Battlestar Galactica, Murder, She Wrote, The Love Boat, Magnum P.I, Diagnosis Murder, The Littlest Hobo, Alfred Hitchcock Presents and many others. He even played Dr. Watson alongside Christopher Lees Sherlock Holmes.

In later life, Macnee became a nudist. After an infancy spent in a dress, a childhood in a kilt and an adulthood in the finest suits money can buy, why not spend an old age in the nip? For a style icon that brought the suave and stylish John Steed to life with effortless grace, charm and virility, one supposes that it must have felt like the next logical step.

R.I.P Patrick, you will be sorely missed.

Trends in … hearing protection

Many business and factories are very well aware of their legal obligations when it comes to occupational deafness, and here in the UK we have the Control of Noise at Work Regulations 2006. Many of the headsets that are listed on Headsetonline.co.uk are designed exactly for these types of industries, with their experience they are a leader in radio headsets and hearing protection equipment. But as the article below explains the protection has to personalised to everyone, so as to make sure that the individual is catered for and protected adequately. The original source of this article can be found here.

Hearing loss is preventable. Why, then, is it still so common? NIOSH notes that occupational hearing loss is one of the most common work-related illnesses in the United States. And according to OSHA, approximately 30 million people in the United States are exposed to hazardous noise on the job.

“Noise-induced hearing loss is generally a gradual and painless process, so many workers don’t consider it a hazard … until it’s too late,” said Katie Mielcarek, marketing manager for Cleveland-based Gateway Safety Inc. Mielcarek went on to say that workers don’t wear hearing protection for many reasons, including discomfort, poor fit and problems with compliance monitoring and trouble inserting earplugs.

Here, industry insiders discuss what’s new and offer advice on hearing protection.

What’s new

“Electronic muffs contain the latest technology designed to protect against environments with impulse noises,” said Eric Moreno, market manager for Cranberry Township, PA-based MSA. “The technology amplifies weak sounds while compressing dangerous noises to a predetermined safe level of 82 dB or lower.” Moreno said this allows face-to-face communication and lets workers hear important sounds, such as warning signals.

Gary Klee, product manager for above-the-neck products at Latham, NY-based Protective Industrial Products Inc., pointed to a “level-dependent system” available with electronic earmuffs. This system has microphones in both ear cups to help limit sounds reproduced through the internal speakers to a safe level, which “allows communication with others while remaining protected against impulsive or hazardous noise,” Klee said.

Advice

Ricardo Allamelou, COO for Miami Lakes, FL-based Cotral Lab Inc., said providing every worker with the exact same type of hearing protection doesn’t make sense. “The protection has to be personalized since overprotection is as dangerous as no protection at all,” he said.

According to Moreno, “Overprotecting can actually increase the danger to a person’s life because this can hinder their ability to hear relevant noises such as warning signals, moving vehicles, other workers, etc.” To reduce the chance of overprotecting, Moreno recommends thoroughly understanding the level of noise in every area of the workplace to determine what level of protection each area needs.

Additionally, be sure your hearing protection is independently, third-party tested to verify noise reduction ratings, Mielcarek said. “This helps communicate quality in an industry where many manufacturers simply mark their products with a standard or a rating, without the testing to back it up.”

The Effect of Earplugs in Preventing Hearing Loss From Recreational Noise Exposure (A Systematic Review)

This is an interesting review of a study of how effective ear plugs are in the workplace. We take for granted that people working in loud factories wear protective hearing, but many of the clubs, pubs, concerts and festivals that have as equal levels of sound. As they say below, it isn’t mandatory to wear ear plugs in such environments, which defies common sense and possibly causes more damage than we understand. Here you can find the original source of the review.

A review of the literature turned up only two high quality studies that looked at whether wearing earplugs to music venues will prevent hearing loss and tinnitus directly afterward.

Dr. Wilko Grolman and colleagues at University Medical Center Utrecht in The Netherlands searched for published studies containing the keywords “music” and “earplugs” and screened 228 resulting papers. All but four were not eligible for inclusion in the review and only two were highly relevant and did not have a high risk of bias, in the reviewers’ estimation.

Two studies simply examined people who chose on their own to wear or not wear earplugs, while two randomized controlled trials tested what happened when participants were assigned to wear earplugs or not.

Two studies reported on hearing loss and tinnitus while one only reported hearing loss.

The two best studies were different enough that the researchers couldn’t combine their data and analyze the results, the reviewers wrote. Both included 29 concert attendees and performed audiometry before and after the concerts. In one study, participants were allowed to choose whether or not they wore earplugs, and only three chose to wear them.

“Frankly, with such a small comparator group between three subjects and the others, it would be hard to assess validity of plugs or not,” said Dr. Jennifer Derebery, president of the Los Angeles Society of Otolaryngology and lead author of the first study.

“We had trained them all in proper insertion, and encouraged but not required wearing them,” Derebery told Reuters Health by email.

In the other study, 15 participants were assigned to the earplug group.

In general, wearing earplugs did reduce hearing loss directly after the concerts, but did not eliminate it completely, as reported online March 3 in JAMA Otolaryngology-Head and Neck Surgery.

“Ear plugs are effective in preventing hearing loss when they are used both correctly and consistently,” said Colleen G. Le Prell, the Emilie and Phil Schepps Professor of Hearing Science at the University of Texas at Dallas, who was not involved in the review.

“This systematic review highlights the very limited data on prevention of recreational music-induced hearing loss using earplugs,” Le Prell told Reuters Health by email.

“At younger ages, loud toys, firecrackers, loud video games, personal stereos or personal music players, lawnmowers or leaf blowers, sporting events or air shows, or other non-music events might be more likely noisy activities than music venue attendance,” Le Prell said. “A significant number of youth are also involved in target shooting activities, which children can get involved with through Boy Scouts or other organizations.”

For teens and young adults, repeat exposures to amplified music at clubs, concerts, festivals, or other related events may damage the inner ear and result in hearing loss, she said.

“Most concerts are both loud enough, and long enough, that they are likely to exceed the total daily exposure allowed by workplace safety regulations,” she said. “Sound exposure also commonly occurs via loud music delivered via personal listening devices, at sporting or other recreational events, and at jobs that involve lawn-mowing, use of power tools, or construction services.”

For workplace noise exposure, “we are not doing a very good job achieving correct and consistent use of hearing protection devices (HPD), including both ear plugs and ear muffs,” she said.

“In the United States, it is relatively uncommon for music venues to provide ear plugs at no charge,” Le Prell said. Even if they were provided, people may need to be educated in why using them is important and in how to use them correctly, she said.

“As a neurotologist, it really is upsetting to see these kids coming in younger and younger with a completely preventable hearing loss,” Derebery said.

Some styles of Bluetooth earpieces

Bluetooth technology has been designed for many different purposes and situations.

Listed below are three of the bluetooth styles that’s currently offered by manufactures all over the United States and abroad.

Bluetooth ear pieces for Mobile Phones

Most people take their mobile phones wherever they go. To work, school, church, parties and all kinds of other events that they may attend. Because these phones have become commonplace in many environments, people have a need to handle them and talk to others when their hands are free. This is also a great reason for individuals who work in certain settings to make sure that they are buying the right style that will best fit their needs.

One specific style that some people may choose is the ear cradle style of headphone. In fact, this kind of bluetooth earpiece is idea for people who want to spend their time working out and performing all kinds of other extracurricular activities. People are also encouraged to buy this kind of style because they may be driving when they receive a telephone call from a family member. Or, they may be working at the job typing a memo or walking around taking care of wide hosts of other kinds of activities that are not conducive to holding a mobile phone by hand to the ear. Whatever the situation, this style of bluetooth earpiece technology is great for many different situations and purposes.

Bluetooth ear pieces and Headsets for Music Lovers

In addition to the cradle style for mobile phones, people should also review other styles as well. One specific style that is also functional in many different settings is the DJ over the head headphones. This style has been designed for the serious music lovers, especially those who can appreciate making distinctions in sounds and beats that come from specific musical instruments like the bass, violin, trumpet and other popular instruments. For those who like and prefer this kind, they will also find that this is one of the best styles for keeping out outside noises that normally interfere with a person’s overall entertainment experience. Also, because they are wireless, they are great for people who like to stay mobile during the day instead of remaining in a sedentary position.

This style is known to be very popular, specifically because it is similar to an actual earbud. An ear bud is also another excellent choice for people who want to remain both active and hassle free. Though this is a great choice for people who like to remain mobile in a wide variety of different situations, one of its main draw backs is that they tend to fall out of the individuals ear. Which means, they can also be lost since it lacks additional support to keep them stabilized inside the ear.

Depicting as a method of communication

This is an interesting review of a paid article, depicting which is represent by a drawing, painting, or other art form can be used as a form of communications, the type of depicting is described here in many different forms and that is where we will allow the article to take up the story.

When we think of language, we usually think of words, phrases, and sentences–strings of abstract symbols. In research over the past 50 years, cognitive and social scientists have developed extensive accounts of how people communicate with these symbols. But when people are face to face, they also communicate with actions that depict people, objects, and events. They create these depictions with their hands, arms, head, face, voice, and entire body, sometimes with other props but often without.

In an article recently published Online First in Psychological Review, Herbert Clark argues that spontaneous depictions like these are missing from general accounts of how people communicate, and that is a major failing. Why? Because depicting is common in everyday conversation and depicting things is fundamentally different from describing things. Also, a great many utterances are “composites” of depicting and describing.

Clark’s point is nicely illustrated in a report, from the New Yorker, of Hollywood director WG telling correspondent TF about having to stop filming in New York because of some falcons nesting on the ledge of a building:

“In L.A., they would have–” He leveled a finger at some imaginary nestlings and made a gun-cocking sound.

As Clark notes, WG could easily have described the scene with the phrase “shot those falcons.” What he did instead was depict the scene with his finger, hand, head, eyes, and voice. The result included a depiction (leveling a finger and making a gun-cocking sound) in place of the phrase “shot those falcons.” Traditional accounts are unable to handle composites like this.

What is depicting? In the theory developed in this paper, to depict something is to stage a scene. When WG leveled his finger at the imaginary falcons, he enacted a shooter in L.A. aiming a rifle at some falcons. And he did that so that his listener could imagine the scene vividly. Depicting is much the same as putting on a play in the theater or engaging in make-believe play.

Depicting, according to Clark, is largely complementary to describing. To begin with, many ideas that are impossible to put into words are easy to depict. Tennis coaches don’t describe how to hold a racket or do a backhand return. They demonstrate it, and in living detail. Music teachers often correct their students by playing or singing what the students should have played or sung. And although it takes years for children to tell coherent stories, they have little trouble depicting stories in make-believe play. They readily enact Cookie Monster, Mother, cops and robbers–and play out what they do.

Depicting is also effective for emotion, excitement, and empathy. In telling stories and passing on gossip, people not only describe, but dramatize what the protagonists said and did, often with passion and attitude. And in apologizing, people not only say “Sorry” but add facial gestures that depict their regret.

The idea, then, is that depicting is a method of communication. Without depictions, talk would be flat, lifeless, and sometimes even impossible.
