What is the power intercepted with the microphone

Reference no: EM13664221

An electronic point source emits sound isotropic ally at a frequency of 3000 Hz and a power of 34 watts. A small microphone has an area of 0.75 cm2 and is located 158 meters from the point source.

a) What is the power intercepted with the microphone?

Pin = ? W

b) How many minutes will it take for the microphone to receive 0.3Joules from this sound?

ΔT = ? min

c) What is the sound intensity level at the microphone from this point source?

Β = ? dB

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

Β = ? dB
