Global Hearing Protection Devices Market: North America has the largest market by 2020

Hearing protection devices (HPDs) help to reduce the amount of sound energy being transmitted into inner ear and protect ear against hazardous noise. Hearing protection device prevents people from occupational hearing loss due to operational or presence of noisy equipment such as stone saws and rock drills in the work place. It also prevents from non-occupational hearing loss due to recreational activities, loud music and fire arms. Hearing protection devices are of many types such as earplugs, earmuffs, hearing band, canal caps and uniform attenuation earmuffs. A good hearing protection device has various characteristics such as good seal, comfortable to wear and leads to effective communication. Shape and size of hearing protection device varies according to individual’s comfort, size of ear canal and environmental conditions. Hearing protection devices are used while working in industries such as gold mines, manufacturing sites, construction, forestry and pharmaceuticals. In addition, working in military can also cause hearing loss as some weapons are so loud that can cause immediate total loss of hearing. Therefore, hearing protection devices are required to protect a person from hazardous noise exposure. Hearing protection device helps to reduce tinnitus-ringing in the ears. They can also prevent person from fatigue and irritability.

North America has the largest market for hearing protection devices followed by Europe. This is due to technological advancement, increasing awareness about noise pollution hazards and high disposable income in the region. Asia is expected to show high growth rate in the hearing protection devices market in next few years due to increasing prevalence of hearing problems and rising government initiatives in this field.

Technological advancement, passing of health and safety regulations, rising noise pollution level and growing demand for user comfort devices are some of the key factors driving the growth for global hearing protection devices market. In addition, their easy use, low cost and increasing consumer health awareness about noise hazards are driving the hearing protection devices market. However, manufacturing with lesser noise and off-shore manufacturing are some of the major factors restraining the growth for global hearing protection devices market.

Ongoing innovation in hearing protection devices would develop opportunity for growth of global hearing protection device market. Rising number of mergers and acquisitions among companies and increasing focus on style, fashion and aesthetic appeal are some the major trends that have been observed in global hearing protection devices market. Some of the major companies operating in the global hearing protection devices market are Honeywell International Inc., 3M, ADCO Hearing Products, GN ReSound, Centurion Safety Products Ltd, Amplifon, Delta Plus, Elvex Corporation, Hellberg Safety AB, Moldex-Metric AG & Co. KG., Siemens Audiology Solutions and Sonomax Hearing Healthcare, Inc.

As this article shows, Hearing protection devices are an important part of a lot of peoples working lives, protecting peoples hearing is a very important part of health and safety legislation.

Idiot In Venezuela Mutilates Himself In Order To Look Like Marvel Comics Villain

Created by writers Joe Simon and France Herron, together with artist Jack ‘King’ Kirby, Marvel Comics’ ‘Red Skull’ character first appeared as an antagonist for Captain America in 1941.

An unreconstructed Nazi supervillain, Red Skull’s plans post-1945 typically centred around world domination, the clever application of his ‘Cosmic Cube’ weapon and a membership in the evil organization ‘Hydra’.

As a result, he has been a popular antagonist in Marvel comic books for several decades and was even selected to be the main enemy of Captain America for the 2011 movie ‘Captain America: The First Avenger’.

One of the most unrepentantly evil Marvel Comics villains, Red Skull isn’t a tortured political idealist like Magneto, or the product of a lousy upbringing like Doctor Octopus. He’s just a Nazi douchebag, plain and simple.

…And now, Henry Damon, a husband and father from Venezuela, has mutilated himself in order to look like him.


Well, he apparently has an appointment booked to have his entire head tattooed red.

Plus, he’s already had his eyeballs tattooed entirely black (which, I have to say I didn’t know was possible) and he has even had sub dermal implants placed under his skin so that his brow and forehead appear ridged and more ‘skull like’.

Next up, he’ll have silicon implants placed under his chin and his cheeks, which will give him the broad, skull-like grimace of the comic book character.

…But by far the most wince-inducing aspect of Mr. Damon’s transformation is that he has recently had most of his nose cut off.

The surgery was performed by Emilio Gonzales (you’ll not the absence of the word ‘doctor’ anywhere in that title), a medical school dropout who earns a living from extreme body modification. In response to critics, Gonzales has said that Damon is “physically and intellectually” a healthy person.

No joke. He really did say that.

OK, so this guy wants to be a Nazi supervillain. In fact, he wants to be a Nazi supervillain so badly that he’s willing to endure no small amount of pain (and spend what is probably a small fortune) on mutilating himself unrecognizably in order to achieve his goal of becoming a Nazi Supervillain from a comic book.

…Yeah, because that’s healthy.

Instead of being offered the psychiatric treatment he obviously needs, Damon apparently passed a number of ‘psychological tests’, but honestly, I can’t imagine any credible, certified psychiatric professional agreeing with that diagnosis, can you? More likely it was the ‘surgeon’, asking him to fill out a few forms in order to cover his ass in case of a lawsuit.

Whatever the reason behind this insanity, there are a great many jokes to be made about this particular idiot. Firstly, if he has no nose, how does he smell? Secondly, he’s cut off his nose to spite his face…And so on.

Joking aside, the really stupid thing is that once this idiot is done mutilating himself, he won’t even own the rights to his own face anymore.

Also, I sincerely hope that he never catches a cold…But that’s more out of concern for the rest of the community than it is for Mr. Damon.

Beloved Wrestling Champion & Promoter Verne Gagne Passes Away, Aged 89

Philosopher Albert Camus once wrote, “What I know most surely about morality and the duty of man I owe to sport”. It is hard to find a more fitting epitaph for Verne Gagne, beloved wrestling champion and influential promoter, who passed away in April of this year.

Verne, who was 89 years old, had been suffering from Alzheimer’s disease and living in a health care facility in Minnesota. However, it would be wrong to dwell on the saddening end of a life as successful and pioneering as that of Verne Gagne, a man who helped to shape the landscape of professional wrestling forever.

At varying times during his life, Gagne was an NFL pro footballer (with both the Green Bay Packers and the Chicago Bears), an alternate for the USA’s Olympic wrestling team, a multi-time amateur wrestling champion, a US marine, a World Champion professional wrestler, a hugely successful promoter and a devoted husband and father.

He trained, or helped to train, many of the biggest and most successful names in professional wrestling history, including future World Champions Ric Flair, Ricky ‘The Dragon’ Steamboat, The Iron Sheik, Bob Backlund, Dick The Bruiser, Sgt. Slaughter, Blackjack Mulligan and ‘Mr. Perfect’ Curt Hennig (father of current WWE wrestler Curtis Axel), as well as industry legends such as ‘Cowboy’ Bill Watts, Larry ‘The Axe’ Hennig (father of Curt), Blackjack Lanza, Baron Von Raschke, Jimmy Valiant, Ken Patera, Ole Anderson, Jim Brunzell and, of course, his own son, Greg Gagne.

Verne Gagne’s story begins on a little farm near Corcoran, Minnesota. He was born in 1926, into a very different world than the one we live in today. As a child, Verne would sit on his grandfather’s lap and listen to wrestling on the radio, as there was no television. As Greg Gagne recalled in the WWE’s 2006 ‘Spectacular Legacy of the AWA’ DVD, it was during one such session that Verne announced his intentions to become a professional wrestler.

Gagne’s amateur wrestling accomplishments speak for themselves, Verne was named the Northwest AAU Champion in 1942, Minnesota High School Champion in 1943 and ‘Big Ten’ Champion in 1944, 1947, 1948 and 1949. He was also crowned National AAU Champion in 1948 and 1949 and was selected for 1948’s US Olympic Team (although he didn’t compete). Gagne also won the NCAA Championship in 1949.

As a promoter, Verne was famous for his emphasis on realistic, ‘scientific’ wrestling, a view that contrasted sharply with the then-WWF’s more cartoonish, family-orientated approach to the sport.

After he turned pro, Verne Gagne became one of the first stars of the early TV era of wrestling, becoming the NWA (National Wrestling Alliance) Junior Heavyweight Champion in the process. In an era of more serious, credible and ‘straight-laced’ wrestling, Verne Gagne exhibited a special kind of charisma, which was backed up by his great work-rate and wholly believable matches. He was also among the first wrestlers to seek endorsements outside of the wrestling world, a move which paid off handsomely at the time and hinted at a high level of business acumen.

Eventually, as Gagne’s popularity with wrestling audiences increased, he became frustrated at the NWA’s apparent unwillingness to allow him a run with the World’s Heavyweight Championship, at that time held by Lou Thesz. Later, when Pat O’Connor was World Champion, the NWA again refused Gagne a title run. Because of this, largely political, limitation, Gagne and his partner Wally Karbo purchased the Minneapolis territory and seceded from the NWA, taking several other territories with them and forming the bedrock of the American Wrestling Association (AWA) in the process.

The AWA proved to be a successful venture and ran between 1960 and 1991. During that time, the company expanded outwards into traditional NWA territories, in a similar (albeit less aggressive) manner to the way that Vince McMahon Jr’s WWF would expand in the 1980’s. Vince Jr has even gone on record to say that if he hadn’t taken wrestling national when he did, Verne Gagne would have done so.

Whilst still an active competitor, Verne drew criticisms in some quarters for constantly booking himself as the AWA World Champion, including one run that lasted from 1968 until late 1975 (he eventually lost the belt to Nick Bockwinkel). However, it should be noted that Verne was undeniably the promotion’s biggest star and that the company was effectively built around his star power. As AWA World Champion, Verne feuded with some of the all-time greats of pro wrestling, stars like Bockwinkel, Fritz Von Erich, Gene Kiniski and The Crusher.

In the 1980’s, the AWA found itself going head-to-head with Vince McMahon’s WWF, a promotion which had been mainly built around the acquisition of Hulk Hogan, a man who had been the AWA’s biggest drawing card not long before. McMahon sought to dominate the wrestling industry by expanding his New York-based territory via cable television. Almost overnight, the AWA’s top talent abandoned Verne’s outfit for the greater exposure offered by McMahon’s WWF and the AWA suffered for a lack of credible main event stars.

Despite this, Gagne’s AWA still offered a very different product to McMahon’s WWF. Where the WWF promoted bodybuilders and super heavyweight ‘big man’ bouts as its top attractions, the AWA was still offering classier, more traditional wrestling matches.

Even under diminished circumstances, the AWA was still an important starting point for many wrestlers to polish their performances and ‘round out’ their ring work and personas.

Over the years, Gagne’s promotion gave a start to many talents that are now regarded as legends within the wrestling industry, including WWE Hall of Famers Hulk Hogan, Shawn Michaels, ‘The American Dream’ Dusty Rhodes, ‘Superstar’ Billy Graham, Scott Hall, Jesse ‘The Body’ Ventura, The Road Warriors and even announcer ‘Mean’ Gene Okerlund, as well as many other stars including Big Van Vader, The Nasty Boys, ‘Mad Dog’ Vachon, Marty Jannetty and Rick ‘The Model’ Martel.

The AWA hung on for as long as it could, but in the wake of the WWF onslaught and an ongoing legal dispute concerning some land he owned along Lake Minnetonka, Verne was effectively forced out of business, going bankrupt in 1991 and later selling his company (and its entire video library) to the WWF.

Despite the ultimate demise of the AWA, Verne Gagne remained one of the most recognised, respected and beloved professional wrestlers of all time. In his 2013 book ‘The 50 Greatest Professional Wrestlers of All Time’, former ‘Wrestling at the Chase’ announcer Larry Matysik ranked Gagne at number 11, saying “As much as his ownership of the AWA leads to criticism that he was its champion, the reality of the promotion’s huge profitability for more than two decades demonstrates that the audience bought him as that champion. And AWA shows drew well even when Gagne was not working”.

Gagne’s legacy as one of the greatest professional wrestlers of all time is already assured. By the time he retired, he was a 15-time World Champion (10 time AWA World Heavyweight Champion, 5 time Omaha World Championship), as well as a Champion in Japan.

He was an inductee into the WWE Hall of Fame, as well as the WCW, Professional Wrestling and Wrestling Observer equivalents. In addition to his incredible in-ring exploits, Verne Gagne should also be remembered as one of the most successful wrestling promoters ever, as well as one of the best teachers the industry ever produced.

For his talent, charisma and freewheeling entrepreneurial spirit, Verne will always be remembered as one of the very best. He was, to quote his son Greg, “a special man”.

Taking The …. Campaign To Urinate In The Shower (In An Effort To Save Water, Apparently), Goes National

Remember that episode of Seinfeld where George Costanza committed a major social faux pas by peeing in the showers at the gym? Well, it turns out that he wasn’t simply being lazy and disgusting. No, he was actively taking a stand to save the world’s water. Or something.

The Go With The Flow campaign, spearheaded by University of East Anglia students Debs Torr and Chris Dobson, is actively trying to encourage students to urinate in the shower as a way of saving water, apparently blissfully unaware that most students (the male ones, at least) probably already do.

In fact, male students have actually been ‘saving water’ for generations now. In addition to mastering the dubious art of shower urination, young men have also managed to ‘save water’ by urinating in other places, too.

Yes, that’s right, by spending literally decades peeing in places as diverse as the alley outside the pub, our mates’ mum’s carpet, empty beer bottles, abandoned port-a-loos The Download Festival and especially Swindon, male students in the UK will probably have saved the equivalent of the Atlantic ocean by the end of the year (possibly even the weekend, if the drinks are cheap enough).

You’re welcome, everyone.

Joking aside (not really), 20-year-old Chris Dobson, who has almost certainly destroyed his own chances of ever getting any female students to join him in the shower, reckons that if every student at his own Uni does just one ‘number one’ a day in the shower, they will save enough water to fill an Olympic sized swimming pool 26 times over.

Of course, even that isn’t particularly impressive, because, if that happened, all the water would just overfill the pool and flood the changing rooms and the car park, making the entire town centre stink of chlorine – and nobody needs that.

His findings also imply that nobody ever pees in public swimming pools. A fact which most of us know to be false.

In fact, according to ‘Pissy Chrissy’ if all UEA students accepted the challenge (as I said, not counting the 50% of them that probably already do), they’d save a combined £125,000 per annum. If the population of East Anglia joined in, they’d be looking at around £42.5 Million.

“We’ve done the maths, and this project stands to have a phenomenal impact”. Said Dobson, accidentally outing himself as a maths nerd as well as a dude that pees in the shower. Sexy prospect.

As you can extrapolate, the numbers would be amazing if the whole country took part in the ‘challenge’ of pissing in the shower once a day, but personally, I think it would be a shame if it was limited to just the shower. Let’s all find exotic places to pee and, when questioned, simply state that we’re doing it for the planet. The power is yours (a brand new no-prize for everyone that gets the reference).

Of course, the ‘Go With The Flow’ initiative only saves water if you flush after every trip to the loo, which is, in and of itself, a huge waste of water. But we already knew that. In fact, the entire thing would appear to be based on assumptions about other people’s urination habits, rather than any sort of quantifiable facts.

On a final note, I just hope some bright spark doesn’t confuse this latest viral campaign with the ‘ice bucket challenge’  – because, quite frankly, nobody needs that.

…And on that note, I’m off to take a quick shower.

PS – by the same logic, you can also save water by taking a dump in your local Sainsbury’s.


As this article shows rules on what information can be relayed from the team to the driver over the radio have been restricted, it actually started last season and has been carried over.

Drivers racing the 2015 season will still be subject to the same radio message restrictions imposed by the FIA last year, with the governing body adding that a “a few more” may be included before the start of the season.

Last year, in response to a belief that information being relayed to drivers by engineers concerning performance was against the spirit of article 20.1 of the Sporting Regulations, which state that “the driver must drive the car alone and unaided”, the FIA contemplated a blanket ban on radio traffic between teams and drivers concerning car and driver performance.

However, following consultation with teams, officials modified their position, saying, at the Singapore Grand Prix, that it would delay restricting car performance messages until this season due to the complexity of introducing the ban at short notice and the potential for differing effects among teams. The FIA issued a revised advisory specifying a range of messages that would no longer be permitted.

According to an FIA spokesman the F1 Strategy Group has now ruled that the current restrictions are sufficient and that race officials will expect teams to continue to respect the technical directive issued in Singapore.

“The Strategy Group, from whom the original request to limit what messages could be delivered to the drivers, now feel that the balance is right by only limiting messages that can be considered driver “coaching”,” said the FIA spokesman. “Therefore, the only messages we will not permit are those listed in TD/041-14 from last year.”

He added, however, that there is still scope for further message types to be prohibited.

“We may add a few to this before the start of the season and re-issue the TD,” he said.

The issue of driver coaching is of particular relevance this year to teams such as Toro Rosso, who are fielding two rookies, including F1’s youngest driver, 17-year-old Max Verstappen.

Screen Shot 2015-02-13 at 14.33.35

Toro Rosso’s Franz Tost was strong opponent of the coaching ban, with the team boss saying last September that the changes contained in the technical directive.

“The changes are absolutely not necessary,” he said during the FIA’s press conference in Singapore.

“All the information the drivers get is also entertainment for the people in front of the TV to hear,” he added.

“For us of course it’s a big disadvantage because the more un-experienced the driver is there’s more information you have to give him.

“For me it’s absolutely nonsense what we are discussing here because in all the other kinds of sports a coach gives some informations, instructions to a football player, for example, on the sideline or wherever.

“This does not mean that the sportsman is not able to do his job, he can do his job, he does do his job, but maybe he can do it in a better way, it’s just a performance improvement. Therefore I don’t understand it.”

Under FIA technical directive TD/041 messages concerning the following are not permitted (either by radio or pit board)

-           Driving lines on the circuit.

-           Contact with kerbs.

-           Car set up parameters for specific corners.

-           Comparative or absolute sector time detail of another driver.

-           Speeds in corners compared to another driver.

-           Gear selection compared with another driver.

-           Gear selection in general.

-           Braking points.

-           Rate of braking compared to another driver.

-           Rate of braking or application of brakes in general.

-           Car stability under braking.

-           Throttle application compared to another driver.

-           Throttle application in general.

-           Use of DRS compared with another driver.

-           Use of any overtake button.

-           Driving technique in general.

Precisely What Is Two Way Communication?

Two-way communication is actually a process through which two parties communicate with one another in a reciprocal manner. Basically, it is something that lets you know that the other person has listened and understood you just perfect. Sometimes, it can also can also be referred to as a form of public relations process where a company and another group share ideas. Here is a detailed description of two-way communication and its applications in the field of business.

The Model

Two-way communication involves an individual or group expressing an idea, which is then received and comprehended by any other group or individual. The message is processed by the receiver who then returns with a message. This message is further received by the first sender, thereby letting both parties to communicate with each other and understand the ideas.

The detailed two-way communication model comprises of several specific steps. The first step is to create an idea that a party wants to deliver. The mode of transmission is chosen by the sender to organise symbols and words for transmission. Then the message is transmitted via the selected method. The next step is about allowing the other party to receive a message, that also transfers the initiative to the receiver. Further, the receiver decodes the message to understood it exactly how it was meant to be according to the sender. Some employers tend to ignore this when providing instructions and assume that telling someone is enough. But it is important to realize that communication is ineffective until there is proper understanding. The last step is the use of the message or communication by the receiver who may discard it, complete the job as directed, save the information etc.

Modes and Applications

People and organisations engage in two-way communication in several different ways through a variety of modes and devices. One of them is face-to-face contact which involves two or more people gathering within the same space and talking to each other directly, thereby allowing for the greatest or best possible communication ranges ensuring the perfect transmission of verbal or non-verbal signals. Another very effective mode is telephone that also lets the voice tone and inflection to help in communication to the meaning of the message. Written formats, whether letters, text messages or emails, can also prove to be quite effective, but usually they lack the nuance and subtlety often found in verbal modes of communication.

When it comes to the features and parameters associated with two-way communication systems, the list ranges greatly from basic hand held two-way transceivers using an individual channel to the very complex systems enabling the sharing of different channels between a large number of users. A number of elements such as geographical location, frequency band, system costs, number of people involved and purpose of communication work as the deciding factor while selecting the type of system. A very essential feature for all types of two-way communication systems is the compatibility and co-ordination of each and every component.

Two-way communication systems have always been used by a large number of businesses for staying connected with their staff or employees while working inside or outside the office premises. Some spheres that use two-way communication regularly are mass communication, public transportation, construction businesses, aviation, advertisement, security, marketing and several others. Police department, fire personnel and emergency response teams also use the two-way communication systems such as telephone, computerized dispatches or radio that allows the professionals to stay informed and updated about the activities of their teams or employees.

Types of Two-Way Communication

When it comes to public relations or marketing, two-way communication basically involves two types of processes – Asymmetric communications and Symmetric communications.

Asymmetric communication takes place between two parties with one of them usually holding more control or power over the process. Typically, this happens in case of a huge company that engages in Public Relations to communicate a variety of ideas to specific markets or general public.

Symmetric two-way communication involves two parties being equal in the process. Such process is generally used by a company to let customers give more feedback that works for bringing improvements to the business. The expression also makes the customer feel a sense of value to the company.

Identify the features of two way communication

Here we Identify the features of two way communication using two way radio, A two way radio is basically a radio that can transmit and receive. Two way radios are simple, convenient and affordable way to stay in close contact with your colleagues, family and friends. Most companies use two way communication systems as a primary source of communication between their workers due to the ease, promptness and convenience offered by this communication system. The following are some of the key features of a two way radio system and their benefits;

900 MHz frequencies

It is essential to point out that radios that operate within this frequency are capable of effectively communicating both indoors and outdoors. This means that they can be used in factories and other workplaces as well as outside when camping or hiking. Most cordless phones also use this frequency. However, the best thing about two way radios that use the 90 MHz frequencies can be used by both individuals and businesses without a problem.

Adjustable gain

Most two way radios come with an adjustable gain feature. This feature allows the user to adjust the sensitivity of the radio’s microphone. This feature is also useful along with the hands free operation feature because it reduces the possibility of unintended noises triggering transmission. It also enhances the ability of the radio to pick up quite voices.

Auto channel change

This feature enables all radios within your group to change to a new channel. This helps in preventing interference from other devices. For you to use this feature, everyone in your group must have two radios that support this feature. In case one channel is not so clear you can simply change and use the channel with little or no interference.

Backlit display

Most two-way communication devices including radios have a digital LCD display feature that displays useful information for instance your current channel. This feature enables you to turn on a lighted display which makes it easier for you to read the information on the screen especially in dark or poorly lit areas.


A channel is a frequency on which two individuals using two way radios can communicate. Typically, there are 14 FRS channels as well as 15 GMRS channels. Two way radios that support both FRS (family radio service) and GMRS (general mobile radio service) have the capability of supporting up to 22 channels. This makes it easy for people to communicate with each other using these radios. However, to effectively communicate, all radios in the group should be set to the same channel.


Two way radios are mobile devices. This means that they are designed for you to move around with them. As a result of this, these radios operate on battery power. Most radios work with standard alkaline AAA or AA batteries. Other models include rechargeable batteries. For those models that come with rechargeable batteries, it is essential for you to always fully charge the batteries before using the radio for effective communication.

Call waiting feature

Just like the regular mobile telephones, two way communication radios also have call waiting feature. If you are already on a call, this feature allows you to receive a notification that someone is attempting to reach you. The latest models will give you an option of immediately accepting the new incoming call or simply reject the call and calling back thereafter.

Call tones

Call tones allows the user to alert the other radio users in the group that he or she wants to talk. It is similar to a telephone’s ringing that indicates that someone wants to talk or someone is calling. Most radios allow the user to select from a variety of call tones.

Intrinsically safe

Also known as IS, intrinsically feature is a protection feature or technique used for safe operation of electronic devices in explosive environments. This concept was solely developed for safety measures specifically operation of process control instrumentation in unsafe areas. This means that two way communication radios can be safely used in hazardous areas without the fear of exploding or causing harm to the user.

In summary, from the above features and benefits of two way communication radios it is clear to suggest that, these radios are convenient, affordable and safe modes of communication that can be used in workplaces as well as at home. They can also be used outdoors during camping, hiking or simply enjoying a shopping expedition in town.
