Anything above 85 decibels may be harmful depending on how long you're exposed to the noise. Anything over 140 may cause instant ear damage.

Answer by  butch (58)

Maximum time a person can be exposed to eighty five decibel without experiencing hearing damage is of eight hours;. Continuous exposure to eighty-five decibel beyond the eight hour limit causes hearing loss. The risk of hearing loss increases in a shorter amount of time to any person. Exposure to level above eighty five decibel, risk of hearing loss increases.

The safe amount is 85 decibels that a person can be exposed to without having damage to the hearing for a maximum of eight hours a day. Different appliances have a level of noise such as a fridge has 50dba, a quiet office as 40dba, a crying baby has 110 dba.

The real answer isn't 85 dba for 8 hours, the accepted OSHA standard, but significantly LESS. Quiet is a good thing, embrace it.

At 91 decibels, your ears can tolerate up to two hours of exposure. At 100 decibels, damage can occur with 15 minutes of exposure. At 112 decibels, damage can occur with only one minute of exposure. At 140 decibels, immediate nerve damage can occur.
