Noise Levels, Hearing Disturbances, and Use of Hearing Protection at Entertainment Venues

Abstract

An investigation of noise levels experienced by patrons and workers at entertainment venues, and a survey of exposure times, experience of adverse effects, attitudes towards noise levels and hearing protection, use of hearing protection, and knowledge of noise induced hearing loss (NIHL) education campaigns were undertaken. Noise level measurements were taken at various points in the venues and a questionnaire was conducted with 303 of the patrons. Mean recorded sound levels exceeded 95 dB (A) and mean exposure time was almost five hours per session. The majority (81%) of respondents had suffered auditory symptoms such as temporary hearing loss, tinnitus and headache. The use of earplugs was low, especially in females and those under 26 years old. The results suggest that regular patrons and staff of these venues are at risk of NIHL. Recollection of a NIHL education campaign does not appear to influence the rate of hearing protection use. Regulating the noise level of venues must be considered as the most effective strategy to prevent NIHL.
