| Apr 10, 2020 at 12:00 | comment | added | Steeven | Does the fan make a constant humming noise? Possibly, what you are experiencing is a trick of the mind, an illusion, where the added constant fan noise is considered as a constant background noise by the brain. This background noise might then "drown out" other noises, because your brain tunes your hearing to the constant background noise. This is just a guess, though, without knowing any details about the setup, effect or activity of the fan | |
