Everyone has heard the old adage “silence is golden,” but just as with lighting and temperature, the comfort zone for the volume of sound is actually not zero. In fact, if the background sound level in a space is too low, conversations and noise can easily be heard, even from a great distance, impacting speech privacy and disrupting one’s concentration. Many organizations use a sound masking system to maintain an appropriate ambient sound level in their facilities, which is typically between 42 and 48 decibels (dB) in commercial interiors.
