Answer:
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
