An electronic point source emits sound isotropically at a frequency of 2 × 103 Hz and a power of 29 watts. A small microphone has an area of 0.72 cm2 and is located 150 meters from the point source.

1)
What is the sound intensity at the microphone ?
I =

2)
What is the power intercepted by the microphone?
Pin =

3)
How many minutes will it take for the microphone to recieve 0.2 Joules from this sound?
ΔT =

4)
What is the sound intensity level at the microphone from this point source?
Β =

5)
What would be the sound intensity level at the microphone if the point source doubled its power output?
Β =

Diffraction occurs for all types of waves, including sound waves. High-frequency sound from a distant source with wavelength 8.70 cm passes through a narrow slit 12.5 cm wide. A microphone is placed 45.0 cm directly in front of the center of the slit, corresponding to point O in the figure 36.5a in the textbook. The microphone is then moved in a direction perpendicular to the line from the center of the slit to point O.At what minimal distance from O...
