5 Critical Facts About Hearing Protection

By Laura Friedman

October is National Protect Your Hearing Month. How many of these facts from Hearing Health Foundation (HHF) do you know?

Fact #1: Noise-induced hearing loss (NIHL) is acquired from excessive noise

• ~30 million U.S. workers are exposed to hazardous noise levels on the job

• Nearly 1 in 5 American teenagers are expected to acquire hearing loss largely due to overexposure of loud sounds

• 25% of Americans age 65-74 and nearly 50% of those 75+ have disabling hearing loss

• Approximately two-thirds of service members and veterans have NIHL or tinnitus, or both

• Many veterans also have processing disorders as a result of blast or high noise exposure

Fact #2: NIHL is preventable. The measures needed to prevent NIHL are simple: “Walk, Block, and Turn. Walk away from the sound source, block your ears using ear plugs, and turn down the volume,” advises Nadine Dehgan, HHF’s CEO.

Fact #3: Musicians are 57% more likely to experience tinnitus and are almost four times more likely to develop NIHL than the general public. Sound onstage can reach up to 110 decibels (dB), the equivalent of a jackhammer. Prolonged exposure to loud noise causes hair cells of the inner ear to be damaged, leading to permanent hearing loss.

Fact #4: A portable listening device at maximum volume (105 dB) is louder than heavy city traffic, drills, noisy subway platform and equal to a table saw. Blasting the volume in earbuds hurts hearing. It is estimated that 20% of teenagers, an age group that frequently uses portable listening devices, will suffer from hearing loss from overexposure to noise.

Fact #5: Steps to identify and prevent hearing loss should begin at birth. In 1993, only 5% of newborns were tested for hearing loss at birth. Thanks to HHF’s instrumental role in passing Universal Newborn Hearing Screening legislation, today that number is 97%. Early detection and intervention helps diminish or even eliminate negative impacts of undetected hearing loss on social, academic and emotional development in children with hearing loss.

Paying Tribute on Armed Forces Day

By Siera Whitaker

May 20 is Armed Forces Day and Hearing Health Foundation is paying tribute to the men and women who serve in our armed forces.

The number one and two war wounds for active service members and veterans are hearing loss and tinnitus, directly impacting their ability to conduct missions and follow instructions. According to the U.S. Department of Veterans Affairs, by the end of 2014 over 933,000 veterans received disability compensation as a result of hearing loss, and about 1.3 million received compensation for tinnitus.

Extended, unprotected exposure to noise that reaches 85 decibels (the sound of a lawnmower) or higher can cause permanent inner ear damage. The Centers for Disease Control and Prevention (CDC) states difficulty with hearing is the third most commonly reported chronic health condition in the U.S.; approximately 40 million Americans ages 20 to 69 have hearing loss in one or both ears, and one main cause is excessive, loud noise.

When it comes to hearing loss and tinnitus, soldiers are at an increased risk. They are susceptible to noise-induced hearing loss (NIHL) because they are exposed to loud machinery and explosions on a constant basis. In combat, soldiers are often exposed to sudden noises, such as from an improvised explosive device (IED) or other similar weapon, which are difficult to predict and be protected against. These sudden noises can result in temporary hearing loss and put military personnel at risk. However, the word “temporary” should be approached with caution. Repeated short-term hearing loss can damage the sensitive hair cells in the inner ear, leading to hearing loss that becomes permanent.

Hearing loss as a result of noise is 100 percent preventable. Wearing hearing protection such as noise attenuating helmets, which use ear cups to protect against hazardous sound, or Tactical Communication and Protective Systems (TCAPS), can go a long way to reduce overall exposure.

Since these brave men and women are disproportionately impacted by hearing loss and tinnitus that likely affects many other aspects of their lives, Hearing Health Foundation is proud to pay tribute to them on Armed Forces Day. If you are a veteran, current service member, or have family or friends who have bravely served our country, please check out our veterans' resources and share your story about hearing loss or tinnitus with us.

Noise-Induced Hearing Loss Affects More Than 50% Not in Noisy Jobs

By Yishane Lee

The Centers for Disease Control and Prevention (CDC) made an announcement Feb. 7 on the dangers of noise-induced hearing loss (NIHL). Among the many statistics cited, the CDC says:

• 40 million U.S. adults ages 20 to 79 have NIHL

• More than half (21 million) with hearing damage do not have noisy jobs

• One in four U.S. adults who say they have good or excellent hearing actually show hearing damage

• Hearing loss is the third most common chronic health condition in the U.S.

• People report hearing loss at a rate nearly double of those reporting diabetes or cancer

The CDC says its latest Vital Signs report, using data from more than 3,500 hearing tests in the 2012 National Health and Nutrition Examination Survey (NHANES), shows “much of this [hearing] damage is from loud sounds encountered during everyday activities at home and in the community,” such as using a leaf blower or going to a loud concert without hearing protection. Nearly three-quarters of those who are exposed to loud noises never or rarely use hearing protection, the report says.

According to the press release, CDC researchers “found that 20 percent of people who reported no job-related noise exposure had hearing damage in a pattern usually caused by noise. This damage—shown by a distinctive drop in the ability to hear high-pitched sounds—appeared as early as age 20.” But it added that while a few studies have linked noise exposure among young people to the use of portable devices and entertainment venues, more research is needed to determine the relationship between this type of early noise exposure and hearing loss in older age.

Untreated hearing loss is linked with anxiety, depression, loneliness, and stress, the CDC says. In addition to causing hearing loss, chronic noise exposure can worsen heart disease and increase blood pressure, among other adverse health effects.

But don’t forget, noise is the only fully preventable cause of hearing loss.

Please see HHF’s resources on NIHL here, as well as our Summer 2015 cover story about NIHL. Taking care of your hearing should always be part of your overall health. If you suspect a hearing loss, get your hearing checked, and if you do have a hearing loss, get it treated. Avoid noisy areas, and wear protective earplugs or stronger when you need them in noisy environments. Download the CDC’s fact sheet here.

Summer Is a Time for Play (and Protection)

By Morgan Leppla

“The best offense is one that does not trigger any defense,” says Daniel Gilbert, Ph.D., a psychology professor at Harvard University.

Gilbert says humans are not hardwired to think long term. When people don’t see a threat as immediate, they are not inclined to take action to mitigate it. This psychological phenomenon is why it’s easy to forego protective measures that’ll make a difference in the long run, especially during one of the most fun-filled times of the year: SUMMER!

With its blaring tunes and crackling fireworks, it makes sense that summer excitement distracts us from remembering the permanent effect of noise on our ears. Loud sounds are more insidious than one might expect. This is in spite of the fact that noise-induced hearing loss (NIHL) can happen at any age, to any race, gender, etc. Hearing loss from all causes is a growing epidemic, affecting nearly 50 million Americans.

Sound volume, length of time listening, and repeated exposure to loudness all can lead to NIHL. One extremely loud sound can cause it, but so can exposure to softer (but still dangerous) sounds over an extended period. To put that into tangible terms, a single loud sound may be a shotgun going off right next to you, while sounds that may damage hearing more slowly are repeated exposure to heavy city traffic, music listened to at a high volume using earbuds, or even regular use of a hairdryer!

So, with all of these potential threats to hearing, what is there to do?

Here is the trinity of protection: WALK away from loud sounds, BLOCK loud sounds with ear protection, and TURN the volume down (when you can control it). These simple actions can have a major impact on your long-term hearing health.

Walk, Block, and Turn!

By Maggie Niu

April 27 is International Noise Awareness Day (INAD), a day dedicated to encouraging people to “do something about bothersome noise where they work, live, and play.”

Every day in our environment we experience sound, whether it’s pleasant, like music, or bothersome, like sirens. Unpleasant or unwanted noisy environments can be dreadful; not only can noise increase our stress level and inhibit us from carrying out daily tasks, but also in the long run overexposure to noise can damage our hearing. This is known as noise-induced hearing loss (NIHL). All too often, we become immune to the constant hum of traffic (about 85 decibels, or dB) and noisy subway stations (95 dB). The Safe and Sound safe listening levels chart, on the left, details the effects of various decibel levels on our ears.

There are two causes of NIHL. One is impulse noise, a one-time exposure to a loud sound such as an explosion. This can cause temporary and/or permanent hearing loss. The other cause of NIHL is continuous exposure to loud noise. This type of hearing loss happens gradually over time.

NIHL affects our inner-ear hair cells (the cells that help us hear) as well as the auditory or hearing nerve. Not only can this type of hearing loss be permanent, it can also lead to tinnitus. Tinnitus is hearing a constant ringing, buzzing, or roaring without an external sound source. It can be in one or both ears and often occurs with hearing loss.

Now the question is: How do we protect ourselves from NIHL? It can be as easy as remembering to Walk, Block, and Turn! Walk away from loud sounds. Block noise by wearing earplugs or other hearing protective devices. Turn the volume down on stereos and personal music devices. If you work in a noisy environment, take proper measures to protect your ears by wearing ear plugs or ear muffs. Being able to hear is important for daily interactions and often taken for granted until it's too late.

Fly

By Chill Kechil

Chill Kechil is a Les Paul Ambassador, helping to educate musicians and others about the risks of noise-induced hearing loss and tinnitus. The New Jersey-based DJ and composer recently released two versions of a song, “Fly,” featuring vocals by Shakila Azhar, in addition to two holiday songs. He is donating a portion of their sales to Hearing Health Foundation. 

As a person with hearing loss, he has made adjustments in order to compose and perform. Here, he talks about the genesis for the songs and what he likes in music.

My latest collaboration is with Shakila Azhar. She is a singer who lives in Singapore, and she happens to be my wife’s cousin. She flies in airplanes for a living and sings at her company’s events. My wife told me Shakila has a killer voice, so when I finally met her we talked about doing a song together. 

Through this song I wanted to capture the spirit of flying, along with her soulful vocals. We recorded “Fly” over a few hours, when she had a stopover in New York City, but I’ll admit it took me almost a year to finish the production.  I hadn’t worked with live vocals before, and I wanted it to be perfect so I really took my time about getting it right. I was also using a new version of my music production software. Shakila’s improvised vocals and lyrics added real soul to the song. 

There are two versions available, a dance version, and a deep house version. I realize now that there could be a connection between my high frequency hearing loss, making it hard to hear higher pitches, and my love for deep house music, which has heavy kick drum beats and a deep bass line. Actually it’s funny, but the idea for the bass line in the deep house version of “Fly” came about while I was doing a holiday song based on Tchaikovsky’s “Dance of the Sugar Plum Fairy” from “The Nutcracker.” 

But it’s not just the deep sounds that I like in my music. The tune should be very melodic. I like women’s vocals floating over the top, and instead of typical three note chords, I like to use four or five notes in each chord like in jazz music (another of my favorite genres). House music combines all of these things—deep sounds, melodic vocals, and rich chords. The software just changes the entire production of a song, letting me visualize the notes and chords while composing. It brings hundreds of instruments to my fingertips.   

When it comes to curating songs for internet radio stations or creating a DJ set, most have kind of a danceable beat. My preferences are really chill, lounge beats and house music that can flow smoothly together from one song to the next. You can say I live up to my Chill Kechil name because most of the songs I produce or play have this chill, danceable beat to them.

Protecting my hearing by covering my ears is always a priority. The headphones I wear for DJing have to isolate the sound from the mixer while also protecting my ears from the ambient sound and noise. This way, I don’t have to turn the volume up as much when I’m mixing a DJ set. The headphones make the bass sound warmer, while reducing the higher frequencies that can hurt the ears and lead to ear fatigue. I always try to be careful by allowing my ears to rest at least a week between DJ gigs, and to check my smartphone’s decibel meter for loudness when catching other DJ or music acts. And, of course it goes without saying... I always have my earplugs handy.

He DJs regularly at Skinny Bar & Lounge on the Lower East Side of Manhattan. Look for him on open turntable nights. Read more about Chill Kechil and his music in Hearing Health's Spring 2015 article here.

Chill Kechil believes in the mission of HHF and its search for a cure for
hearing lossand tinnitus. He is donating a portion of sales of “Fly" and the
holiday songs “Dance of the Sugar Plum Fairy" and “Carol of the Bells” to HHF.

HHF Celebrates National Protect Your Hearing Month

By Emily Shepard

October marks National Protect Your Hearing Month, part of the American Academy of Audiology’s (AAA) campaign to raise public awareness about hearing protection. Through extensive research and programming such as the Safe and Sound Program, Hearing Health Foundation has contributed greatly to this awareness. To celebrate National Protect Your Hearing Month, HHF has compiled a list of 5 Must Know Facts about Hearing Loss Prevention.

Fact #1: Noise Induced Hearing Loss (NIHL) can be contracted in a variety of environments.  Around 30 million U.S. workers are exposed to hazardous noise levels. The National Institute on Deafness and Other Communication Disorders (NIDCD) reports that 26 million Americans between the ages of 20 and 69- around 15% of the population- have NIHL due to exposure to loud sounds or noise at work or in leisure activities. 60% of military service members have NIHL or tinnitus, or both. Given this huge percentage, it’s unsurprising that active and veteran service members rank hearing loss and tinnitus as their top health concern.  

Fact #2: NIHL is the most preventable type of hearing loss. The measures needed to prevent NIHL are easy and simple. Just remember the following three words: Walk, Block, and Turn. When exposed to loud sounds, walk away. Block noise by wearing earplugs or other hearing protective devices when involved in a loud activity. Turn down the sound on stereos and mp3 devices. These are some of many ways you can help protect your hearing. Ultimately, the idea is to keep an eye (or an ear) on noises that seem hazardous or alarming.   “For more information about how to protect your hearing, please visit our partner’s page, It’s a Noisy Planet. Protect Their Hearing®.

Fact #3:  Half of classical orchestral musicians experience hearing loss. But that doesn’t mean you should! As stated in our blog post, “The Danger From Noise When It Is Actually Music”, musicians practice or perform up to eight hours a day. Sound levels onstage can reach up to 110 decibels (dB), the equivalent of a jackhammer! Prolonged exposure to 85 dB (the sound of heavy traffic), causes hair cells of the inner ear to be permanently damaged and can lead to hearing loss. With an 85 dB minimum for this risk, musicians exposed to jackhammer-levels are in dangerous territory. Attending an orchestra show or any other musically-vibrant production may not put you at the same risk of musicians, but it is still important to take cautionary measures. Find a seat that isn’t too close to the front of the stage and bring earplugs in case the music gets too loud. If the sound becomes especially loud, it might be worthwhile to leave early. Since soundtracks and recordings of shows are often available for purchase, there’s no need to stay out of fear of missing out. Remember, safety should always come first.  

Fact #4: What commonly used portable device is louder than a hair dryer, dishwasher, heavy city traffic, and a subway platform? The correct answer is an MP3 player at maximum volume (105 dB). Listening to your favorite artists or podcasts on blast may seem like a thrill, but there’s nothing fun about subjecting your ears to hazardous noise levels. 1 in 5 teenagers, an age group that frequently uses MP3 players, suffer from hearing loss. The Palo Alto Medical Foundation reports that 12.5% of kids between the ages of 6 and 19 suffer from loss of hearing as a result of using ear phones or earbuds turned to a high volume. So to play it safe, HHF suggests no more than 15 minutes of unprotected exposure at or above 100 decibels.  

Fact #5: Steps to prevent hearing loss should begin the moment someone is born. In 1993, only 5% of newborns were tested at birth for hearing loss. Thanks to HHF’s instrumental role in establishing Universal Newborn Hearing Screening legislation, this percentage increased dramatically. By 2007, 94% of newborns were tested. Early detection of hearing impairments in infants can help to diminish or even eliminate negative impacts that would otherwise harm their future development. Therefore it is important to screen infants for hearing impairments, preferably before they are discharged from the hospital. You can learn about the different types of tests hospitals use to screen infants here.  

Make Listening Safe

By Sloan Blanton

Our ears are one of our most precious commodities. With our ears we are able to communicate with our peers, enjoy the beauty of music, tune into the natural world around us and become aware of safety hazards, such as sirens. Some people are born without the ability to hear, and for thousands of years those individuals lived without any legitimate hearing solutions. In the past 150 years, numerous technological advancements have emerged, providing hearing assistance through the use of hearing aids, assistive listening devices, cochlear implants, and more.

However, today's increasingly industrialized society poses a new risk. A growing number of people are prone to noise-induced hearing loss. Our smartphones and personal audio devices increase our vulnerability, especially when we are tuned in for extended periods of time. Concerts, nightclubs, and sporting events make us prone to hearing loss as well.

For all of these reasons and more, the First International Conference on Prevention and Rehabilitation of Hearing Impairment established the annual International Ear Care Day in 2007. The event is held on March 3 each year to build advocacy and promote hearing care in countries all around the world. This year's theme is: "Make Listening Safe."

The World Health Organization (WHO) works closely with this event, releasing an annual assessment of each country's status in providing quality ear care services. This year, the WHO found startling numbers to be true about the state of hearing loss in the world; over 1.1 billion young adults ages 12 to 35 are at risk for "recreational hearing loss." In this age group, 43 million people currently deal with the unfortunate effects of hearing loss, whether it is noise-induced or through birth defects or illnesses. Recreational hearing loss leads to many harmful effects. Physical and mental health can be affected, as well as employment and education opportunities. Hearing loss may also lead to attention-seeking behaviors and learning disabilities.

“As they go about their daily lives doing what they enjoy, more and more young people are placing themselves at risk of hearing loss,” says Dr. Etienne Krug, the director of the WHO’s Department for Management of Noncommunicable Diseases, Disability, Violence, and Injury Prevention. “They should be aware that once you lose your hearing, it won’t come back. Taking simple preventive actions will allow people to continue to enjoy themselves without putting their hearing at risk.”

Both intensity and duration affect safe listening levels. The safe level at 85 decibels (dB) is eight hours of continual exposure. The number drops drastically at 100 dB to just 15 minutes. Exposure to these loud sounds usually leads to temporary hearing loss and a ringing sensation in the ear (tinnitus). When the exposure is particularly loud, regular, or prolonged, it can lead to permanent hearing loss and a lack of speech comprehension, and is damaging the ear's sensory cells. High-frequency sounds are typically the first to be impacted.

To reduce the risk of noise-induced hearing loss, set the volume on your personal audio device to no greater than 60 percent of the maximum volume. Wear earplugs in bars, at sporting events, and in other loud places. Even using headphones allows sound to be customized for individual listeners. Take short breaks while in loud environments to reduce the harmful effects of noise exposure, such as avoiding loudspeakers.

By having one’s ears checked regularly, individuals are able to monitor the onset of hearing loss before it becomes a serious concern. There are also many smartphone apps that provide useful information regarding volume levels to inform users of whether they are exposing their precious ears to risky sound levels.

Hearing Health Foundation is a proud supporter and partner of International Ear Care Day. It is worth marking on your calendar in an effort to curb the trend of noise-induced hearing loss while encouraging mankind to develop lasting solutions to lifelong problems.

Show our Veterans that You Are Hear For A Cure

By Pallavi Bharadwaj

Can you imagine returning home after serving in the military for your country without your hearing and with constant ringing in your ears?

Credit: @srz/Unsplash

Tinnitus and noise-induced hearing loss (NIHL) are the number one and two war wounds among veterans returning home. In the past decade, over one million service members have been impacted by tinnitus, hearing loss, and/or other auditory disorders.

To provide support to the community of veterans with hearing problems, Hearing Health Foundation (HHF) launched a veterans’ resource center on our website. This section is designed to help veterans cope with hearing loss and tinnitus. Resources such as research updates on new treatment options, stories from veterans who have been affected, and topical features from Hearing Health magazine can be accessed here.

Most importantly, we would like to share with our service members the exciting prospect of a cure for hearing loss and tinnitus through our Hearing Restoration Project (HRP). The HRP is working to translate the ability in chickens to restore hearing for humans in order to deliver a cure for veterans and for all those suffering from hearing loss and tinnitus.

If you are a veteran, current service member, or have family or friends who have bravely served our country, review these resources about hearing loss and tinnitus.
