A fight breaks out at club event in Hollywood. As a result, a chair hits a 4.0 meter long metal baron the stage. A microphone at the other end of the bar picks up two pulses of sound (over the roar of the crowd, of course). One of the pulses traveled through the metal bar, the other through the air. The pulses are separated by 9.00 m.
A. Find at what speed did the sound pulse travel through the metal bar?
B. If the microphone measured the intensity level of the impact at 115 dB, find what was the decibel level of the sound at the door of the club 15 meter away?
