Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.

Is 50 dB loud for a fan?
40 dBA is a normal office noise level. 50 dBA of constant noise will induce fatigue. You will be quick to notice that using more than one fan, each smaller but each running at slower speeds results in a much quieter, less-maddening experience. The faster the fan the bigger the noise.
Is 130 dB hearing Safe?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
How long can you listen to decibels?
The safe listening time is cut in half for every 3-dB rise in noise levels over 85 dBA. For example, you can listen to sounds at 85 dBA for up to 8 hours. If the sound goes up to 88 dBA, it is safe to listen to those same sounds for 4 hours.

How many dB does it take to go deaf?
Sound is measured in units called decibels. Sounds at or below 70 A-weighted decibels (dBA), even after long exposure, are unlikely to cause hearing loss. However, long or repeated exposure to sounds at or above 85 dBA can cause hearing loss.
How many dB is a car horn?
109 decibelsSound levels of typical car horns are approximately 107–109 decibels, and they typically draw 5–6 amperes of current.
How long can you be exposed to 120 decibels?
Scientists recommend no more than 15 minutes of unprotected exposure to sounds that are 100 decibels. In addition, regular exposure to sounds at 110 decibels for more than one minute risks permanent hearing loss.
How many dB can kill you?
150 decibels is usually considered enough to burst your eardrums, but the threshold for death is usually pegged at around 185-200 dB. A passenger car driving by at 25 feet is about 60 dB, being next to a jackhammer or lawn mower is around 100 dB, a nearby chainsaw is 120 dB.
