'''Fan noise''' can be a persistant minor irritant. The good news is that [[:Category:Noise|noise reduction]] is fairly simple to install, and can reduce noise levels massively.
===Buying quiet=== Extractor fans cover the noise level range from under 40dB to over
50dB. Choosing a low noise fan at purchase time can reduce noise by upto 10dB.===Flexible mounting=== Fans can be mounted on rubber washers (or other flexible mounts) to prevent transmission of vibration to the wall or joist.
To be effective, screws should be done up until there is no slack movement, but no further. Overtightening would eliminate the flexibility of the mounting.
