Explanation:
Detailed explanation-1: -Sound Intensity and Decibels The equation used to calculate this intensity, I, is:II=PAWhere P is the power going through the area, A. The SI unit for intensity is watts per meter squared or, Wm2Wm2.
Detailed explanation-2: -Kbps = bits per second / 8 = Bytes per second x 60 seconds = Bytes per minute x 60 minutes = Bytes per hour. Bits per sample x samples per second = bits per second / 8 = Bytes per second x 60 seconds = Bytes per minute x 60 minutes = Bytes per hour of mono. More items
