What is an acceptable level of noise in decibels?
Decibel Level Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. 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.
Are silenced guns still loud?
According to a fact sheet from SilencerCo, a Utah-based silencer manufacturer, a 12-gauge shotgun equipped with a silencer registers 137 decibels and a silenced . 22 rifle is muffled to 116 decibels, slightly louder than an ambulance siren. Still loud, just not eardrum-busting loud.

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.
