engine emits sound uniformly in all directions, radiating an acoustic power of 3.65 × 10 5 W. 3.65×105 W. Find the intensity of
Art [367]

Answer:

130.2dB

Explanation:

The formula for determining the intensity of a wave is expressed as

I=\frac{P}{A}\\

Where P is the power in watts, and A is the area of the sphere formed by the wave

Data given

Power,P=3.65*10^5W

distance,d=52.7

Hence since the distance represent the radius, we can determine the area of the sphere formed

A=4\pi r^{2}\\A=4\pi *52.7^{2}\\A=34900.45m^2

The intensity can be computed as

I=\frac{3.65*10^5}{34900.45}\\ I=10.46W/m^2

we can convert to decibel

I=10log\frac{10.46}{10^{-12}} \\I=130.2dB
