The Occupational Safety and Health Administration (OSHA) Noise Standard (29 CFR 1910.95) requires employers to have a hearing conservation program in place if workers are exposed to a time-weighted average (TWA) noise level of 85 decibels (dBA) or higher over an 8-hour work shift.
85 dBA is the “Action Level” where hearing protection is required. 90 dBA is the OSHA, 8 hour average exposure limit. 100 dBA exposures longer than 15 minutes are not recommended. Regular exposure to 110 dBA of more than 1 minute risks permanent hearing loss.
What Do These Levels Sound Like?
|Noise Level (dBA)||Common Outdoor Activities||Common Indoor Activities|
|110||Jet Aircraft Fly Over||Rock Concert|
|100 – 90||Gas Lawn Mower at 3 ft||Kitchen Blender|
|80 – 70||Passenger Car at 65 mph at 25 ft||Vacuum Cleaner at 10 ft|
|60 – 50||Electrical Transformers at 100 ft||Large Business Office|
|40 – 30||Bird Calls, Rural Area||Library|
