Protecting Yourself from Noise Induced Hearing Loss at Live Concerts

If you have ever been at a concert and thought “This music is simply too loud,” it doesn’t necessarily mean that you’ve become too old for this sort of music. This reaction could be your body’s means of telling you that you are in danger of hearing impairment. If, after you’ve left the concert, and for the following few days you’ve had a ringing in your ears (tinnitus) or experienced difficulty hearing as well as usual, you may have experienced noise-induced hearing loss, or NIHL.

This can happen even after brief exposures to loud noises, and occurs because high decibel sounds can result in physical damage to the very small hair cells that receive auditory signals in the interior of the ear and transmit the signals to the brain, where they are interpreted as sounds. Typically, the NIHL resulting from a single exposure to very loud music or noise is short-lived, and will go away within a couple of days. However in the event that you continue to expose yourself to loud noise or music, it can cause tinnitus that doesn’t go away, or a long-term loss of hearing.

How much damage very loud music does to a person’s hearing is dependant upon a couple of things – how loud the music is, and how long you are exposed to it. Noise levels are measured on the decibel scale, which is logarithmic and therefore difficult for many people to understand; a rise of ten decibels on the scale means that the sound at the higher rating is two times as loud. Thus the noise of noisy city traffic (85 decibels) isn’t just a little bit louder than the sound of ordinary speech (65 decibels), it’s four times louder. A rock concert, at which the sound level is commonly in the range of 115 decibels, is 10 times louder than standard speech. In addition to precisely how loud the music is, the second factor that determines how much damage is done is how long you are exposed to it, the permissible exposure time. Hearing loss can occur from being exposed to sound at 85 decibels after only eight hours. In contrast, the permissible exposure time that you can be exposed to music at 115 decibels without risking hearing loss is less than one minute. Add to this the knowledge that the sound level at some concerts has been recorded at over 140 decibels, and you have a high risk predicament.

Projections from audiologists claim that by the year 2050 up to fifty million Americans will have sustained hearing loss resulting from exposure to very loud music. Bearing this in mind, many live concert promoters and concert venues have started supplying sound-baffling ear plugs to attendees for a minimal charge. One well known UK rock and roll band actually collaborated with an earplug manufacturer to offer them free of charge to people attending its concerts. Some concertgoers have reported seeing signs in the auditoriums that proclaim, “Earplugs are sexy.” Earplugs may, in fact, not be very sexy, but they could possibly save your hearing.

Any of our hearing specialists here would be pleased to supply you with information about earplugs. In case a noisy rock and roll concert is in your near future, we strongly suggest that you consider wearing a good pair.

On-the-Job Noise-Induced Hearing Impairment: Professions With Greater than Average Risk

Could your job be contributing to your hearing impairments? Extreme noise levels are one of the most common causes of hearing damage. Worrying about your ability to hear is a natural response for anyone working at a high-noise profession.Approximately 30 million employees are at risk of hazardous noise exposure on the job according to the Centers for Disease Control.Workers in high-noise job areas must equip themselves with the specifics of occupational hearing safety and keep an open conversation with their companies.

All employees should assess their own work surroundings for high-noise levels, especially anyone in the following jobs.

  • Manufacturing – The largest number of permanent hearing losses suffered in the workplace are in manufacturing. Manufacturing industries routinely expose workers to machinery and equipment which generates upwards of 90 decibels of noise for extended period of time.
  • Construction – Construction workers rank next to the highest for permanent hearing loss disabilities suffered in the workplace. Construction equipment routinely exposes staff to heavy machinery that produces over 90 decibels. A Washington State study of construction workers discovered that in spite of being exposed to noises exceeding 85 decibels during 70 percent of their shifts, construction workers only wore ear protectors 20% of the time (or less).
  • Chemicals Industry – Exposure to certain substances (especially those that contain n-butyl alcohol, toluene, lead and carbon monoxide) has been connected to increased hearing loss by itself. These particular chemicals now known to combine with noise to cause increased hearing loss.
  • Miners – According to the Center for Disease Control, 49 percent of male miners are expected to have a hearing impairment before age 50 – versus 9 percent of the general population – rising to 70% by age 60.
  • Motorcycle Courier – Research into motorcycle noise – with and without helmets – under various driving conditions at speeds between 45 mph to 65 noted that the noise measured ranged from 70 decibels to 128 decibels.
  • DJs and Nightclub Staff – Everyone that works in a nightclub – security, wait staff, bartenders – is at risk, not just the musicians. In a controlled research study, noise levels of up to 108 decibels were recorded in the nightclubs. The average noise level for a typical nightclub outing was 96 decibels which is over the noise level at which the provision of hearing protection is required for employers in industry. The study concluded that Disc Jockeys are at substantial risk of developing noise-induced hearing loss and sound exposure in nightclubs frequently exceeds safe levels.
  • Musicians – Across practices, studio recording and performances, musicians are constantly engulfed in sound. The list of famed music artists with permanent hearing problems or tinnitus keeps growing each and every year. Well known artists on the current list include Ozzy Osbourne, Neil Young, Phil Collins, George Martin, Jeff Beck, Eric Clapton, and Ludwig van Beethoven.
  • Band & Orchestra – A study on the noise exposures of classical musicians experienced during both performances and rehearsals found that the brass section averaged 95 decibels while the strings and brass section averaged 90 decibels. Top volumes were 130 decibels in the percussion and brass sections. A different Swedish research project showed that 59 out of 139 orchestra musicians had hearing losses greater than that normal for their ages.
  • Airport Staff – The noise of an airplane engine is one of the loudest auditory occupational hazards, with noise levels at a shocking 140 decibels.
  • Firefighters and Paramedics – All those sirens squealing add up over time. Several research studies have examined the frequency of hearing disabilities in firefighters and emergency vehicle drivers with most concluding that firefighters suffer increased hearing loss relative to the general public of the same age.
  • Military – Noise-induced hearing loss is the number one disability among US military personnel. According to the Deafness Research Foundation, over 65 percent of combat troops returning from Afghanistan are afflicted by noise-induced hearing loss.
  • Plumbers – The CDC website states that 48% of plumbers reported that they had a perceived hearing loss.

Buying Advice for Kids’ Headphones

One thing you can look forward to if you have kids is that sooner or later they will ask you to buy them some headphones to work with their music players, game systems and computers. And there are valid reasons for this, because headphones can enhance the experience with these multimedia, but at the same time there are certain characteristics you should look for when you buy.

An important feature that most buyers would not normally consider is making sure that the headphones fit correctly. Headphones which are intended for grownups are made for their full-sized heads, and will not simply not fit the right way on kids, they won’t provide a complete spectrum of sound to them. You should not rationalize the size difference by believing that the kids will grow into them. In reality, the constant fidgeting and adjusting will probably result in a shorter life due to breakage. Headsets made for children are developed with a growing child in mind. Most have an adjustable head band which allows your child to obtain a perfect fit now and for years to come.

The most crucial characteristic you should look for, however, is that the headphones are equipped with some type of Sound Limiting Technology. By nature, children will use the highest possible volume settings to completely immerse themselves in the experience. Parents recognize that this is a very terrible idea which could contribute to future loss of hearing. Seeking out headphones that have a volume limits built in – somewhere around 80 to 85 decibels – is the most effective way to combat this tendency. This recommendation is just as true for ear buds or similar devices that one inserts into the outer ear canal as it is for over-the-ear headphones.

A different thing take into consideration is durability and sturdiness, because kids are hard on delicate things, and certain headphones can be very fragileindeed. Refer to consumer guides or parents’ magazines to learn which models of headphones have a reputation for durability and for lasting a long time. Make sure you balance this desire for durability with a bias toward light weight, however because you don’t want your kids to be wearing headphones that are too heavy for their body and head.

Whichever model headphones you go with, make an effort to restrict your children’s use of them to just a couple hours daily. Being inundated by sound all day, even if the earbuds or headphones restrict the volume level, can still create subtle damage to youngster’s sensitive ears.

Tinnitus in Your Ears? Music Can Help You

Sound is an integral part of our world, but like most things, its impact on us depends on both the quality of the sounds we hear, and the quantity of them. Listening to music can be soothing and relaxing, but it can also be annoying and irritating if the volume is excessive.

When it comes to music and other sounds, quality is subjective, one that depends on individual preferences; the quantity of it (as measured by volume, in decibels), however, is incredibly objective, and can be measured. We know that when people are exposed to very loud sounds or music above a specific decibel level for prolonged amounts of time, those sounds can harm the miniature hair cells in our ears, and cause noise-induced hearing loss (NIHL). It has been estimated that in our raucous society, as many as one in five Americans have developed some amount of tinnitus (a constant ringing in the ears) or other forms of hearing loss as the result of NIHL. Even muted sounds below 10 decibels (half the volume of a whisper) may cause stress and anxiety if you are exposed to them long enough; have you ever been kept awake at night by the sound of a dripping faucet or ticking clock?

But despite the fact that sound can be a cause of stress and hearing damage, it can also be a tool to treat the effects of hearing damage. Many people have experienced the soothing effects of soft music, the relaxing sound of falling water or ocean surf, or the meditative sounds of chanting or Tibetan singing bowls. Increasingly, these types of sounds are being used by psychologists to treat anxiety rather than create it, and by audiologists to treat hearing problems such as tinnitus rather than cause them. In hospitals and clinical situations, music therapy has been successfully used to accelerate recovery from operations, to aid stroke victims during their recovery, and to impede the development of Alzheimer’s dementia. People have successfully used white noise generators (which create a blend of frequencies similar to the sound of ocean surf) to help people conquer insomnia and sleep disorders, and to reduce their perceived awareness of background sounds in noisy environments.

More specifically related to hearing loss, sound and music therapy is being used more and more to treat tinnitus by creating what specialists call a threshold shift, which allows tinnitus patients to psychologically disguise the constant buzzing or ringing sounds they hear. By using specialized tones or carefully chosen music tracks, hearing specialists have been able to teach tinnitus patients to retrain their minds to choose the sounds they want to hear over the ringing sounds caused by the tinnitus. It’s not as if the ringing disappears; it’s more that the music therapy has allowed them to focus their attention somewhere else, and thus no longer feel the anxiety and stress that tinnitus causes.

For tinnitus sufferers seeking new remedies, music therapy is worth looking at. Give us a call to go over your specific situation.

Afghanistan and Iraq Veterans Left with Tinnitus and Hearing Loss by the Millions

Veterans – especially those who’ve served in conflict zones – have much higher percentages of hearing loss than the general public. Seeing as 20% of the public in the United States has some level of hearing loss, the rates among veterans are alarmingly high. Hearing loss and tinnitus have become the most common service-related disabilities among troops who served in Afghanistan and Iraq. In 2011, the number of veterans receiving disability benefits as a result of hearing loss or tinnitus (148,000) was more than triple the number of veterans receiving benefits for post-traumatic stress disorder (42,700). The result is a public health problem of the highest order, one that cannot help but get worse in the future, as the noise-induced hearing loss experienced by these soldiers gets worse as a result of normal age-related hearing loss. The tinnitus component is often worse because of the side effects. The constant ringing in the ears is know to lead to headaches, mood changes, anxiety, insomnia, vision changes and depression. On top of that, many veterans have suffered profound levels of hearing loss and deafness. According to Brett Buchanan, a VA-accredited insurance claims agent who has made a study of hearing loss in veterans, “The military, in general, is just a high noise-producing environment.” In the Navy, most sailors work below decks in high-noise environments, filled with “the constant drumming of engines and metal-on-metal noise.” In the Army or Marines, soldiers spend most of their day inside or near noisy vehicles such as tanks or transport carriers. Of course, in a war zone this background noise is often punctuated by the sounds of gunfire and explosions, creating pretty much an ideal environment for creating hearing loss. Many efforts are made to reduce the risk and exposure. The US military provides hearing protection and noise-reducing ear plugs. These safety measures are used consistently in training, but are a secondary concern in actual battle. When faced with bullets flying, IEDs and mortars exploding, the soldier isn’t going to turn back for ear plugs. It is worth noting that a soldier wearing ear plugs may not be able to hear whispered instructions or may miss clues about the enemies whereabouts.

The military is doing what it can to increase the use of hearing protection by providing more sensitive earplugs that block loud noises but allow soldiers to hear even the faintest normal conversations. While better solutions are in the works, the Veteran’s Administration has become the largest buyer of hearing aids in the US. Hearing aids are provided at little or no cost to veterans who need them. If you are (or know) a veteran who has suffered hearing loss, encourage them to get tested. Our expert staff would be happy to determine the extent of the loss, recommend solutions and help you navigate the VA benefits system.

How Professional and Amateur Musicians Can Decrease the Odds of Future Hearing Loss

What do Phil Collins, Jeff Beck, Eric Clapton, and Ludwig van Beethoven have in common, besides all being musicians? They all suffered permanent hearing loss, directly as a result of playing their music.

I often work with musicians who have experienced hearing damage as a result of their longtime love of playing music. Exposure to loud music causes noise-induced hearing loss (NIHL), which can produce a temporary ringing in the ears (tinnitus); if you continue to expose yourself to the loud music, the condition can become permanent.

The hearing loss can happen to any musician, whether they play in a rock band, in a symphony orchestra, in a chamber music group, or just play at home when rehearsing. Hearing loss can occur when exposed to any sound over 85 decibels (dB) in volume for prolonged lengths of time. An electric guitar played onstage generates 120dB, but a violin can produce 103dB, and thus cause almost as much hearing loss. In fact, audiologists researching hearing loss in musicians have found that overexposure to sound while rehearsing adds up to more hours than they spend on stage performing.

Fortunately, there is something you can do to protect your hearing – invest in a pair of earplugs; not the cheap foam earplugs you find in drugstores, but high-quality musicians earplugs. Such earplugs were invented over 20 years ago by a company called Etymotic Research, and their design is still used by most of the manufacturers of specialized earplugs for musicians. What makes them better than the cheap foam earplugs is that they allow you to hear music and speech accurately, at all frequencies, just at lowered volumes.

You can find universal-fit musicians earplugs in most stores that sell musical instruments, starting at about $15 a pair. But for the musicians I see – whether they play professionally or just for fun – I recommend custom-molded musicians earplugs with Etymotic filters, because of the greater protection they provide. Comfortable even with extended wear for long periods of time, custom-molded earplugs block undesirable sound allowing the music to come through undistorted and without damaging hearing. They are also more expensive than the universal-fit earplugs, but when you consider that hearing damage is irreversible, the investment is more than worth it.
