Hearing Conservation

Sound volume is measured in units called decibels (dB). Sounds of less than 75 decibels, even after a lengthy exposure, are unlikely to cause hearing loss. However, extended or repeated exposure to sounds at or above 85 decibels (approximately the level of a vacuum cleaner) can cause hearing loss. Loud sound does not have to be physically painful to be harmful. The damage can occur at different thresholds depending upon the duration and intensity of the noise. The more intense the noise, the more quickly it can cause damage. A general rule to follow is that if you need to raise your voice to be understood by someone standing three feet away from you, then the noise is probably too loud.

If you work in any area where you have to raise your voice to be understood at arm's length or if you feel your work area may have unhealthy levels of noise, contact EHS at (805) 756-5555, so that noise monitoring can be conducted.
