About 3 min NIOSH sets a recommended daily exposure limit of 85 dBA for 8 hours. Every 3 dB increase halves the safe time — 88 dBA for 4 hours, 91 dBA for 2 hours, and so on. This tool converts your typical week into a NIOSH daily-dose score. 1 / 6 ## Your workplace noise, most days: Quiet office / home (<70 dBA) Cafe / classroom (~75 dBA) Warehouse / kitchen (~85 dBA) Machine shop / construction (~95 dBA) Airfield / mining (100+ dBA) Next ## Frequently asked ### How loud is too loud? 85 dBA for 8 hours is the NIOSH recommended limit.

Well-inserted foam plugs give ~25-30 dB attenuation and are excellent for lawn equipment and gunfire. For concerts and music, custom musician's plugs preserve sound quality by reducing volume evenly across frequencies. ### Can noise damage be reversed?
