What is the total acoustic power output of the speaker

Reference no: EM13702840

Solve the all parts of given problem:

Problem: A loudspeaker at a rock concert generates 10-2 W/m² at 24.0 m at a frequency of 1.0 kHz. Assume that the speaker spreads its energy uniformly in three dimensions.

Part A: What is the total acoustic power output of the speaker?

.............. W

Part B: At what distance will the intensity be at the pain threshold of 1.0 W/m2?

............... m

Part C: What is the intensity at 45.0 m?

............... W/m²

I need the right answer and steps of solving these questions. Thanks!
