Noise levels in nightclubs may induce hearing loss

A new study raises concerns about the noise level in nightclubs. Researchers in Southern California have found that the average continuous level of noise in some nightclubs is at least 91.2 dBA (A-weighted decibels). Club goers may suffer noise-induced hearing loss from just one night out on the town.

This latest research on hearing loss and other hot topics within the otolaryngology—head and neck surgery specialty will be presented at the 2016 Annual Meeting & OTO EXPO℠ of the American Academy of Otolaryngology—Head and Neck Surgery Foundation (AAO-HNSF) in San Diego, from Sunday, September 18, to Wednesday, September 21. Among the studies slated for presentation on Sunday and Monday are:
