15.49 - 30 seconds of exposure to 115 dB sound can damage your hearing, but a much quieter 94 dB may begin to cause damage after 1 hour of continuous exposure. You are going to an outdoor concert, and you'll be standing near a speaker that emits 47 W of acoustic power as a spherical wave. What minimum distance should you be from the speaker to keep the sound intensity level below 94 dB? Express your answer to two significant...

2. From a vantage point very close to the track at a stock car race, you hear the sound emitted by a moving car. You detect a frequency that is 0.852 times smaller than that emitted by the car when it is stationary. The speed of sound is 343 m/s. What is the speed of the car? 3.Hearing damage may occur when a person is exposed to a sound intensity level of 90.0 dB (relative to the threshold of human...
