Nov 4, 2020 · Here is a helpful equation to convert sones to decibels: dB = 33.2*log 10 (Sones) + 28. 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) Fx2D.
