SUMMARY
The discussion focuses on calculating the distance required to perceive a 4000Hz sound at the same intensity level as a 500Hz sound, which is 4.0x10^-4 W/m² at 1.0m from the speaker. It is established that intensity is proportional to the square of the frequency. To solve the problem, one must first determine the intensity at 1m for the 4000Hz sound and then apply the inverse square law to find the necessary distance for the intensity to equal 4.0x10^-4 W/m².
