A microphone is 9.3 m from a point source of sound. The microphone detects an intensity of 121.8 pW/m2. (Recall the pico prefix means LaTeX: 10^{-12} 10 − 12 .) Assuming the generator is perfectly efficient, what power in pW is required to produce the detected sound? Report your answer to the nearest pW.

At point A, 3.20 m from a small source of sound that is emitting uniformly in all directions, the intensity level is 51.0 dB. a) What is the intensity of the sound at A? I got I = 1.26×10−7 W/m2 and it is correct. b)How far from the source must you go so that the intensity is one-fourth of what it was at A? I got R1 R1 = 6.40 m and it is correct. c) How far must you...

A source emits sound waves equally in all directions. The intensity of the waves 2.50 m from the source is 1.90 times 10^-4 W/m^2. Find the power of the source, If the diameter of your eardrum is 8.4 mm, how far from the source do you have to be located so that your ears combined receive 0.42 times 10^-12 J of energy each second?
