10. [prob36(a)] Sound level L, in units of decibels (dB) is determined by: Lp = 20 log10 () where p is the sound pressure of the sound, and Po = 20 x 10-6 Pa is a reference sound pressure (the sound pressure when Lp = 0 dB). Now the sound pressure of a passing car is 80 × 10-2 Pa. Determine its sound level in decibels
