Hearing Conservation

Noise induced hearing loss is the most common workplace injury. With the help of our certified hearing conservationists and a good hearing conservation program, preventing hearing loss due to hazardous noise is possible. Elements of an effective hearing conservation program include: Noise Assessment, Controlling Exposure, Hearing Protection, Audiometric Testing, Training & Education, Hazard Communication and Monitoring Performance.


    Protecting workers from hazardous noise levels is the responsibility of the organization.

    Using dosimeters and/or noise level meters, hazardous noise is detected and employees requiring inclusion in the hearing conservation program are identified. Quantifying the noise also helps in the selection of hearing protection ensuring adequate noise reduction rating to prevent hearing loss. Noise assessments should be done every 2 years or when there are changes to machinery, processes, environment, etc.


    Establishing a baseline audiometric test and monitoring the hearing of the work force is the only way to verify the effectiveness of a hearing conservation program.  It also identifies workers with noise induced hearing loss and offers the opportunity to educate on prevention. Audiometric testing should be conducted annually if workers are exposed to noise above 80 dB. A management report is provided which identifies employee issues, trends and recommendations to improve the effectiveness of the program. 


    Done in conjunction with audiometric testing, training & education is very successful in achieving employee buy-in of the hearing conservation program and ownership of hearing loss prevention.  Workers are taught to recognize hazardous noise at work and during leisure time, and the implications of this exposure on hearing and health. The employee is observed putting on their hearing protectors to ensure proper use and fit.
