Noise-Induced Hearing Loss (NIHL)
With the help of modern technology, our society has become noticeably louder in recent years. Sound systems are more powerful. CD and MP3 players let us listen to music wherever and whenever we want. Movies, concerts, bars, even health clubs "pump up the volume" for our enjoyment. As a result, we are all exposed to more loud sound than ever before. Cumulative exposure can result in a gradual loss of hearing function.
What is NIHL?
NIHL stands for Noise Induced Hearing Loss, a totally preventable decline in hearing ability caused by overexposure to loud sounds.
Safe Hearing Levels
Anything over 85 decibels (dBA) is potentially damaging. The louder the sound, the shorter the safe exposure time. Any exposure over 115 dB may pose a serious health risk.
Define "Noise"
In terms of NIHL, "noise" means anything you can hear. Music, jet planes, power tools, driving with the window down, whatever. If it's over 85 dB, it's potentially damaging.
But I like loud music!
So do we! But like so many enjoyable activities, there are limits. A two-hour rock concert that averages 100 dB is a full daily allotment of loud sound, according to OSHA. If that same concert averages 105 dB, safe exposure time is only one hour! And remember, this assumes that you have no other exposure over 85 dB that day.
Don't local noise ordinances protect me?
Not really. Unfortunately, enforcement at concerts is often lax, especially once the show starts. A typical rock concert often attains levels of 110 to 120 dB, enough to cause damage to the unprotected ear.
How can I tell if I have NIHL?
NIHL is insidious. In many cases, there are no obvious symptoms like ringing in the ears, buzzing, etc., and the onset is usually slow and subtle. The only way to tell for sure is to have your hearing tested regularly by an audiologist. Tracking the results of annual hearing tests will show any changes in your hearing.
What are the warning signs of NIHL?
Ringing in the ears (tinnitus), buzzing, temporary loss of high frequencies, hypersensitivity to sound, and difficulty hearing in noisy environments are all warning signs. But remember: Many people don't experience any symptoms! That's why regular hearing check-ups are so important.
What can I do to protect myself?
Most obviously, turn it down! But in general, try to be aware of the sound levels around you, and avoid loud sounds whenever possible. Wear hearing protection devices like our Musicians Earplugs when listening to loud music. See our Hearing Tips for Musicians page for more ideas.
