Unlike other injuries, there is no visible evidence of noise-induced hearing loss [NIHL]. It is not traumatic or usually even noticed when it occurs. Rather, hearing impairment accumulates over time, its effects realized long after the damage has been done. Worse, noise-induced hearing loss is permanent and irreversible. However, with proper education, it is 100% preventable.

In this section you’ll find several resources to help you learn about hearing conservation – a hearing protection glossary, information on upcoming seminars, downloadable presentations by the Hearing Conservation team at Howard Leight, and the Sound Source™ article series, addressing topics in hearing protection and conservation.
