The decibel level of a signal can be expressed as, L = 10 log (S / Sref) (1), S = signal - intensity or power level (signal unit), Sref = reference signal - intensity or power level (signal unit). To find how many decibels are in one sone, plug one into the equation: dB = 33.2*log 10 (1) + 28 = 28 dB If you have decibels and want to find the number of sones, use this equation: Sones = 10 ( (db-28)/33.2) These equations may look daunting which is why we made calculation easy for you. Consequently, the sone scale of loudness is based on data obtained from subjects who were asked to judge the loudness of pure tones and noise.
