Preventing Hearing Loss: Noise Exposure

Noise is one of the most common causes of hearing loss.  Noise Induced Hearing Loss (NIHL) can be due to both occupational and recreational exposure.  Hearing can be permanently damaged in an instant, such in the case of a gun shot at close range.  Exposure to dangerous noise levels on a daily basis can cause irreversible hearing damage, this one of the most common occupational illness in the United States.  According to the National Institute on Deafness and Other Communication Disorders (NIDCD), 30 million Americans are exposed to dangerous noise levels everyday.  Another 10 million have already experienced permanent hearing damage from noise exposure.

Warning Signs

Noise Induced Hearing Loss (NIHL) develops gradually. Some early symptoms are turning the volume up on the TV or having difficulty hearing in groups or in the presence of background noise. As hearing loss begins to worsen it becomes difficult to understand normal conversation in quiet settings. Hearing evaluations are recommended to identify any existing hearing loss or recognize the need for further steps to prevent additional loss.

Warning Signs of Excessive Noise Exposure:

• You cannot hear someone three feet away.
• Your ears hurt after leaving a noisy area.
• You have sudden difficulty understanding speech after being exposed to noise.
• Your ears are ringing or buzzing after exposure to noise.

Prevention

NIHL can be prevented. Wearing Hearing Protection Devices (HPDs) when exposed to excessive noise either at work or play is the best prevention. Being aware of which noises can cause damage is also important. Sounds above 85 decibels can cause damage. These include everything from jet engines, lawn mowers, motorcycles, chainsaws, stereos, and powerboats. A good rule is that if you have to raise your voice over the noise to talk to someone that is close to you than it is probably loud enough to cause damage.

Hearing Protection Devices

Hearing protection devices are powerful tools in preventing NIHL. These devices come in a variety of styles: earplugs, earmuffs and digital technology. This digital technology is for those individuals that need both amplification and hearing protection. These devices are available as in-the-ear styles as well as behind-the-ear. Advanced digital technology allows for environmental awareness while simultaneously protecting your hearing. These new devices provide the most advanced electronic hearing protection available toady having digital wind reduction as well as feedback cancellation.
