Keep in mind that range hoods with larger motors and suction power will create more noise. dBm Calculator: As we know Decibel in dB can be calculated as: dB= 20log(V1/V2)= 10log(P1/P2) If we put P2 = 1mW = .001 watt then it . Sone measurements are a linear table, meaning that a doubling of perceived sound represents a doubling of the sone value. Lets say we have a bathroom exhaust fan that runs at 1.5 Sones. B = 10 * log ( I / I0 ) B = 10 log(I /I 0) Where B is the sound intensity decibels I is the sound intensity (W/m^2) I 0 is the reference sound intensity (equal to 10 -12 W/m^2 for ambient noise) Range hoods with a delay shut-off feature can also help.
