97. ••The steady drone of rush hour traffic persists on a stretch of freeway for 4 h each day. A nearby resident undertakes a plan to harness the wasted sound energy and use it for her home. She mounts a 1-m? “micro- phone" that absorbs 30% of the sound that hits it. If the ambient sound level is 100 dB, calculate the amount of sound energy that is collected. Do you think her plan is "sound"? How could you improve it? SSM
