Hearing Conservation

    Protect Your Workers With a Hearing Conservation Program

    Do you know how to protect your worker’s hearing?  If your workplace has a lot of loud noise, you need a hearing conservation program.   An effective hearing conservation program should include the following elements:

    ·      Training and Information

    ·      Management Leadership and Employee Involvement

    ·      Noise Control Measures

    ·      Audiometric Testing

    ·      Noise Exposure Monitoring/Worksite Analysis

    ·      Employee Notifications

    ·      Recordkeeping

    ·      Hearing Protector Evaluation

    When developing a hearing conservation program, an experienced industrial hygienist can help you decide which workers need personal noise exposure monitoring and the most cost-effective way to conduct a noise survey.  The noise survey results are then used when determining the allocation of resources for training, medical surveillance and control measures.


    The time-weighted averages (TWAs) obtained from the survey should be recorded on each representative workers’ audiogram.  This may be useful in the future if an audiologist is asked to determine if a hearing loss is work-related.  The industrial hygienist uses the TWA to evaluate hearing protectors used in the workplace.  Recommendations are made when choosing between ear muffs, custom earplugs, electronic headsets, foam plugs, etc.
