Sound level in units of decibels (dB) is determined by:LP 20 10 p p0 ----⎝⎠ where p is the sound pressure of the sound, and Pa is a reference sound pressure (the sound pressure when dB). (a) The sound pressure of a passing car is Pa. Determine its sound level in decibels. (b) The sound level of a jet engine is 110 decibels. By how many times is the sound pressure of the jet engine larger (louder) than the sound of the passing car?
