You can take steps to prevent noise-induced hearing loss, such as wearing ear protection when necessary. The A-weighted sound levels closely match the perception of loudness by the human ear. Occupational Noise Exposure: Considerations for EHS Managers Occupational noise-induced hearing loss (ONIHL) is the most prevalent occupational disease in the world. The NIDCD maintains a directory of organizations that provide information on the normal and disordered processes of hearing, balance, taste, smell, voice, speech, and language.

Examples include: Controlling noise exposure through distance is often an effective, yet simple and inexpensive administrative control. : Occupational hearing loss is preventable through a hierarchy of controls, which prioritize the use of engineering controls over administrative controls and personal protective equipment. This protective reflex, known as the "aural reflex," does not actually react fast enough to provide protection against impulse sounds and the muscles do not stay contracted long enough to provide protection from long-term steady exposure.
