Sound Masking is the method of adding ambient noise to a space to “drown out” background distractions and conversations, without impairing the ability to communicate. This is often the least understood sound control methodology, since it is counter-intuitive that adding noise into a space may improve the acoustics within.

WebDec 2, 2011 · For example, a two decibel increase multiplies the sound by 1.259 2 = 1.585. If you keep going up to ten decibels, we recover 1.259 10 = 10. With four fans, the power they put into sound is four times as much. If you work it out, you'll find that six decibels gives a noise energy increase of 1.259 6 = 3.98.
