In addition to hearing sensitivity varying with frequency, in complex sounds some sound components partially mask other components. The decibel scale and the intensity values it is based on is an objective measure of a sound. Sone to Decibel Calculator Most of us are familiar with noise level measurements in decibels. 1 Pa = 1 pascal = 1 N/m 2. For best results, have the appliance professionally installed to ensure proper venting. Range hoods typically produce between 3 and 7 sones of sound.
