Below is a chart to help you better understand the causes and eects of dierent sound levels. The noise levels are rated in dB (decibels)
Environmental Noise Noise Level dB Possible Eects of Exposure
Quiet Library 30 dB No Eect - Normal
Normal Conversation 60 dB Comfortable Hearing
City Trac (inside car) 85 dB
Maximum Level before hearing damage begins. OSHA recommends no more
than 8 hours of exposure to sound levels of 90 dB daily.
Power Saw at 3’ 110 dB Permanent Hearing Loss likely due to prolonged unprotected exposure.
Jet Engine at 100’ 120 to 140 dB
At 125 dB the human ear begins to experience pain that can lead to permanent
hearing loss even during short unprotected periods.
