3. An outside stereo speaker at a concert emits sound waves with a power output of 92.23 W and frequency 1014.87 Hz. A concertgoer stands at a distance (a) 8.16 m from the speaker. What intensity does he detect in dB? DOPPLER EFFECT: (b) Suppose the concertgoer starts running at speed v away from the speaker. What is the speed v of the runner if he hears a frequency of 960.04 Hz?

. A person stands directly in front of Iwo speakers that are emitting the same pure tone. The person then moves to one side until no sound is heard. At that point, the person is 7 in from one of the speakers and 7.2 in from the other. What is the frequency of the tone being emitted?
A community is concerned about a plan to bring train service to their downtown from the town’s outskirts. The current sound intensity level, even though the rail yard is blocks away, is 70 dB downtown. The mayor assures the public that there will be a difference of only 30 dB in sound in the downtown area. Should the townspeople be concerned? Why?
(a) Ear trumpets were never very common, but they did aid people with hearing losses by gathering sound over a large area and concentrating it on the smaller area of the eardrum. What decibel increase does an ear trumpet produce it its sound gathering area is 900 cm2 and the area of the eardrum is 0.500 cm2, but the trumpet only has an eficiency of 5.00% in transmitting the sound to the eardrum? (b) Comment on the usefulness of the decibel increase found in part (a).
