Preventing Noise-Induced Hearing Loss

is150 September 02, 2011
Noise, or unwanted sound, is a by-product of many industrial processes. Sound consists of pressure changes in a medium (usually air), caused by turbulence or vibration. These pressure changes produce waves emanating away from the turbulent or vibrating source. Exposure to high levels of noise causes hearing loss and may also put stress on other parts of the body. The extent of damage depends primarily on the intensity of the noise and the duration of exposure.

Noise-induced hearing loss can be temporary or permanent. Temporary hearing loss results from short-term exposures to noise, with normal hearing returning after a period of rest. Generally, prolonged exposure to high noise levels over a period of time gradually causes permanent damage. For most effects of noise, there is no cure. Therefore, controlling exposure to excessive noise is the only way to preserve your hearing.

This paper summarizes the potential health effects of noise, applicable workplace noise exposure standards and regulations. Noise measuring methods are also described.

Noise-induced hearing loss is an increasingly prevalent disorder that results from exposure to high-intensity sound, especially over a long period of time. Hearing loss caused by exposure to loud sound is preventable. To reduce their risk of noise-induced hearing loss, adults and children can do the following:
• Understand that noise-induced hearing loss can lead to communication difficulties, learning difficulties, pain or ringing in the ears, distorted or muffled hearing, and an inability to hear some environmental sounds and warning signals
• Identify sources of loud sounds that can contribute to hearing loss and try to reduce exposure

Hearing loss exists when there is diminished sensitivity to the sounds normally heard. The term hearing impairment is usually reserved for people who have relative insensitivity to sound in the speech frequencies. The severity of a hearing loss is categorized according to the increase in volume above the usual level necessary before the listener can detect it. Thanks.
