Question

A jet engine emits sound uniformly in all directions, radiating an acoustic power of 3.23 × 105 W. Find the intensity of the sound at a distance of 41.7 m from the engine and calculate the corresponding sound intensity level.

Question 3 of 9 Map sapling learning A jet engine emits sound uniformly in all directions, radiating an acoustic power of 3.23 x10s W. Find the intensity of the sound at a distance of 41.7 m from the engine and calculate the corresponding sound intensity level. Intensity: Number WIm ntensity level: Number dB

Explanation / Answer

intensity = power/surface area

I = (3.23*10^5)/(4*pi*41.7^2)

I = 14.78 W/m^2

-------------

intensity level = 10*log(I/Io) = 10*log(14.78/10^-12) = 131.7 dB
