In support of the Hearing Conservation component of the Army Hearing Program, Army industrial hygienists are responsible for conducting noise surveys in the workplace to identify military and civilian workers potentially exposed to noise hazards. During the survey, the magnitude of exposures is determined through sampling techniques. Sampling data is then used to determine effective engineering, administrative, and personal protective equipment controls and medical surveillance recommendations. Noise assessment surveys are conducted upon request. The surveys evaluate the magnitude of potential occupational noise exposures to military and civilian personnel in order to quantify the exposures and select effective protective measures.
