Noise exposure and hearing loss from leisure activities.
Proceedings of the NIH Consensus Development Conference on Noise and Hearing Loss, Washington, D.C., January 22-24, 1990. 1990 Jan; :55-58
Published studies dealing with noise levels and potential effects of some noisy leisure activities are reviewed. Attendees at rock concerts or noisy discotheques are routinely exposed to sound levels above 100 decibels-A (dBA). While exposure to 100dBA for a few hours weekly or monthly apparently presents little risk to the attendee, it may represent significant risk of noise induced hearing loss (NIHL) for anyone involved in these activities on a daily basis. Noise exposure from jazz concerts exceeded those from symphony concerts, but fell below those for attendees at rock concerts. The increased use of personal stereos and cassettes, particularly in youth and children, has caused concern. Several general statements can be made concerning these devices. First, at the highest volume settings, most of these devices can produce sound levels in excess of 110 to 115 decibels sound pressure level at the ear; they are able to produce hazardous sound levels possibly causing NIHL over prolonged periods; and studies suggest that only a few individuals prefer to use the sets with the volume adjusted so high as to be harmful. Those experiencing a feeling of fullness in the ear, dullness of hearing, or tinnitus should be counseled to modify listening habits to reduce the risk. Hazards associated with outdoor lawn tools, cordless telephones, power equipment, and guns were noted.
