Noise‑induced hearing loss (NIHL) is a frequent problem in
industrial settings, especially where a high noise level (more
than 85 dBA) is present. Noise has deleterious effects on health
and performance, including NIHL.[1] NIHL is the second most
common form of acquired hearing loss, after presbycusis.[2]
NIHL is permanent, irreversible, but preventable.[2]
