Abstract
This testimony summarized the position of NIOSH regarding an occupational noise standard. Concern is expressed regarding the 90 decibels-A (dBA) limit, based on analysis of data from various studies indicating that as many as ten to 15 more persons per hundred may incur a hearing handicap as a result of a working lifetime of exposure to 90dBA versus 85dBA. A 90dBA exposure limit may not provide sufficient protection to higher frequencies in the human audiogram which are more vulnerable to noise damage. The proposed 90dBA standard may allow excessive exposures for periods of less than 8 hours. The adoption of a less stringent noise exposure limit for hearing conservation could permit other forms of noise induced effects of possible consequences to safety and health. Various studies are currently underway to gather data on the proposed standard. A laboratory study is examining whether the senses of vision, balance, touch and thermal sensation can be affected by short term high level continuous noise and impact sounds that do not exceed the exposure limits proposed by the Department of Labor. Studies have indicated that recurrent, prolonged exposure to noise, typical for many heavy industries, may contribute to various chronic stress related disorders.
