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).
The goal is to prevent permanent hearing damage from noise, which can be achieved by using proper hearing protection and limiting exposure to loud noises. NIOSH has set recommended exposure limits (RELs) of 85 dB(A) for an 8-hour time-weighted average (TWA).
