Datasheet

Below is a chart to help you better understand the causes and effects of different sound levels. The noise levels are rated in dB (decibels)
Environmental Noise Noise Level dB Possible Effects of Exposure
Quiet Library 30 dB No Effect - Normal
Normal Conversation 60 dB Comfortable Hearing
City Traffic (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.

Caution
DO NOT operate any motor vehicle or heavy machinery while listening to or wearing your headphones. Doing so is not only dangerous
to you or others but illegal in many states. Listening or wearing headphones reduces your ability to hear sounds around you such as
emergency vehicle sirens or the horn from another motorist.
