Find the intensity I of the sound waves produced by four 60-W speakers as heard by the driver. Assume that the driver is located 1.0 m from each of the two front speakers and 1.5 m from each of the two rear speakers.

The intensity of the sound waves produced by four 60-W speakers as heard by the driver is 173.33 W/m²

Explanation:

Sound intensity (I) is given as;

I = P/r², W/m²

Where;

p is power measured in watt (W)

r is the distance from the speaker measured in meters (m)

The total intensity produced by the four speakers, can be calculated as follows;

I = 2*(60/1²) + 2*(60/1.5²)

I = 120 W/m² + 53.333 W/m²

I = 173.33 W/m²

Therefore, the intensity of the sound waves produced by four 60-W speakers as heard by the driver is 173.33 W/m²
