Question:
An audio engineer takes decibel readings at distances of r m and r m from a concert stage speaker during a sound check. When he is r from the speaker, the engineer registers a decibel level of beta dB on his loudness meter.
What is the intensity of the sound, I in watts per square meter, that is measured by the loudness meter when the engineer is a distance of r from the speaker?
How much power P in watts, is coming from the speaker during the sound check at distance r
Assuming that the speaker output does not change between the two measurements at r and r what sound intensity level beta in decibels, will the loudness meter report when the engineer is at a distance r from the speaker?
