Continued exposure to noise of sufficient intensity may result in hearing impairment. If an individual must raise his voice to communicate with someone nearby due to noise, it is likely that the level of this noise may be of sufficient amplitude to cause hearing loss. Persons exposed to noise levels exceeding 85dBA should be issued hearing protectors. These protectors should be comfortable to wear and offer sufficient attenuation to prevent hearing loss. Employees should be instructed in the use and care of their protectors and they should be periodically monitored on the job to ensure that they continue to use them correctly. Supervisors should identify employees who require hearing protection. Sound level meters are available from the EHS office.
