Avoid hazardous sound environments. Otherwise, wear hearing protection devices (HPDs).

Monitor sound pressure levels above 85 dB. In the absence of a sound meter, the general rule to follow is that if you are in an environment where you must raise your voice to be heard, you may be risking permanent, hearing loss and you should limit your exposure.

 

Take 15-minute "quiet breaks" every few hours if you are exposed to sound pressure levels above 85 dB. Refer to the guidelines above for safe exposure durations.

 

Musicians and other live entertainment professionals should avoid practicing at "concert hall levels" whenever possible.

Have your hearing checked annually by a licensed audiologist.

When worn correctly, foam HPDs attenuate (reduce) sound levels reaching the ear. Noise reduction ratings (NRRs) for foam HPDs range from 20 to 35 dB and provide greater attenuation at high frequencies than at low frequencies. Most foam HPDs are designed for one-time use.

 

Custom-molded HPDs provide equal ("flat") sound attenuation for high and low frequencies and are
re-usable. They have NRRs of 15 to 25 dB and are designed for people who rely on their ability to hear high and low frequencies without distortion. These HPDs are custom-made by licensed hearing healthcare providers and offer a comfortable form fit and long-term wear.

Ear muff HPDs are easy to take on and off but require a solid shell and acoustic seal around the ear to effectively attenuate noise.
