RECOMMENDATIONS TO REDUCE HEARING LOSS FROM RECREATIONAL SOUND EXPOSURE
This detailed review article by Richard Neitzel, PhD, and Brian Fligor, PhD, in the Journal of the Acoustical Society of America discusses the risk of noise-induced hearing loss from recreational sound exposure.
The abstract contains the important conclusions, which are amply supported by the article itself. They are:
- The recommended occupational exposure limit is 85 A-weighted decibels (dBA)*. Some exposed workers will develop hearing loss from this noise exposure. To eliminate the risk of hearing loss, a 24 hour average of 70 dB is recommended.
- It is possible that occupational noise exposure may have worse impacts on hearing than equal exposures to recreational noise. But the application of statistical hearing loss models developed from occupational noise data to estimate the impacts of recreational noise exposure is nevertheless warranted.
- A recreational noise exposure limit of 80 dBA for 8 hours, equivalent to 75 dBA for 24 hours, should prevent hearing loss for adults. For children and other vulnerable individuals, e.g., those who already have hearing loss, the lower exposure level of 75 dBA for 8 hours, or 70 dBA for 24 hours, is appropriate.
Common non-occupational noise exposure sources include public transit, appliances, power tools, personal music players and other personal listening devices, musical instrument practice and performance, concerts, sports events, and parties.
Protecting hearing is simple. Eliminate high noise exposures where possible, increase the distance between you and noise sources around you, and use hearing protection (earplugs or ear muffs).
Because if something sounds too loud, it is too loud, and your hearing is at risk.
