Ind amplitude of pressure wave generated by snow mobile

Reference no: EM13553051

The sound level in decibels is typically expressed as ? = 10 log (I/I0), but since sound is a pressure wave, the sound level can be expressed in terms of a pressure difference. Intensity depends on the amplitude squared, so the expression is ? = 20 log (P/P0), where P0 is the smallest pressure difference noticeable by the ear: P0 = 2.00·10^(-5) Pa. A snow mobile has a sound level of 96 dB, find the amplitude of the pressure wave generated by this snow mobile.
