Speaker Sound Q Calculator

The measure of the directional property of sound is the directivity index expressed in decibels. The directivity index and the theoretical q of loud speaker can be calculated using this sound q calculator based on the horizontal and vertical coverage.

Formula:

q=(10*π/(sin-1(sin(h/2)*sin(v/2))))/10 d=(10*10*(0.43429*log(q)))/10 Where, q = Speaker Sound Q (Theoretical Loudspeaker) h = Horizontal Coverage v = Vertical Coverage d = Directivity Index
