3. The relation between the intensity I W/m² and the intensity level D dB of a sound can be represented by the following formula: T D=10log 10-12 P.9 of 9 -8 (a) If the intensity of the sound in a bookstore is 108 W/m², find the intensity level (in dB)of the sound. (b) If the intensity level is halved now, find the intensity (in W/m 2 ) of the sound.
