A concert loudspeaker suspended high off the ground emits 33.0 W of sound power. A small microphone with a 0.600 cm2 area is 52.0 m from the speaker. What is the sound intensity at the position of the microphone

The sound intensity at the position of the microphone is

Explanation

Sound intensity is given by the formula

Where is the sound intensity, is the power and is the area.

Since the loudspeaker radiates sound in all directions, we have a spherical sound wave where the radius r is the distance of the microphone from the speaker.

∴ is given by where is the radius

From the question, = 33.0W, = 52.0m

∴

Hence, the sound intensity at the position of the microphone is 9.71 × 10⁻⁴ W/m²
