The Hearing Conservation Program is administered by the Office of Environment, Health and Safety (EH&S).


    The Hearing Conservation Program is provided when an employee's noise level is above an 8-hour TWA of 85 dBA and consists of:

    1.  Assessment of employee noise exposure level

    2.  Implementation of engineering, administrative, and/or personal protective equipment controls to reduce noise levels

    3.  Audiometric tests: baseline, annual, and post employment

    4.  Employee training/education

    5.  Record keeping of noise exposure level, training log, and audiometric exam
