How loud is too loud for a baby?
Extremely loud – 100 decibels. No more than 15 minutes of unprotected exposure is recommended. Dangerously loud – 110+ decibels. Regular exposure of more than one minute risks permanent 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.
What is the loudest fan for sleeping?
