In order to help reduce hearing loss, the Occupational Safety and Health Administration regulates noise levels in work environments. However, hearing aids are the primary rehabilitative service provided for individuals with an occupational hearing loss. Very little is being done to monitor hearing aid use in the work environment. Noise which may be safe to an unaided ear can amplified to levels that are damaging to the ear when a hearing aid is being worn.

Industrial workers who have sustained hearing losses often wear hearing aids on the job in order to hear their co-worker's speech. However they risk damaging their hearing further by amplifying the high levels of background noise typical of such environments.
