Recreational activities that can put you at risk for NIHL include target shooting and hunting, snowmobile riding, listening to MP3 players at high volume through earbuds or headphones, playing in a band, and attending loud concerts.

He had a good 50 dB to 55 dB of noise-induced hearing loss at 28 years old. As far as a rule of thumb goes, the figures we got in our studies were that people using that standard earbud could listen at about 80 of maximum volume for 90 minutes per day or less without increasing their risk for noise-induced hearing loss. That said, studies we’ve done on behavior show that the type of earphones has almost nothing to do with the level at which people set their headphones.

Studies show that noise-induced hearing loss due to headphone use is on the rise 3The Prevention of Noise Induced Hearing Loss in Children. Pioneering studies on the effects of noise trauma involved the recording of gross electrophysiological potentials, such as the cochlear microphonics and compound action potentials, to monitor cochlear function (e. Recognizing that there is a real problem, many studies have focused on some of the specific causes, such as very loud signals from some cordless telephones 62, the types of headphones or earphones used in personal entertainment devices 63, and the actual levels of sound that are generated by earphone transducers 64, 65.

What are some strategies to prevent noise-induced hearing loss? Someone in the audience who attended this one show for 4 full hours was exposed to 105 dB equivalent continuous sound level. A Rising Generation. Noise-induced hearing loss occurs, simply, when sensitive cells in the inner ear are exposed to loud noises. In-ear headphones, like the earbuds that come with an iPod, send loud music straight into your ear and directly toward sensitive cells.

Tune in to these noise-induced hearing loss campaigns for better hearing health.

Numerous research studies found hearing loss among young people throughout the world, caused not only by listening to amplified sounds at a high volume, but also at a normal volume with prolonged listening in excess of seven hours a week (1). Evidence of concern regarding hearing loss due to headphone use is reflected throughout the world leading to the completion of studies in countries such as Canada, Israel, Korea, and the United States involving young people, teens, and adults through their early thirties (3,4,5,6).
