While permanent noise-induced hearing is often preventable through proper hearing protection, limiting the amount of time one is exposed to high levels of noise is still required. As such a widespread issue, NIOSH has been committed to preventing future hearing loss for workers by establishing recommended exposure limits (RELs) of 85 dB(A) for an 8-house time-weighed average (TWA).
Noise-induced hearing damage can be prevented with proper hearing protection. However, limiting exposure to loud noises is still essential. To address this widespread issue, NIOSH has set recommended exposure limits (RELs) of 85 dB(A) for an 8-hour time-weighted average (TWA).
