Problem 6:  An audio engineer takes decibel readings at distances of r1 = 14 m and r2 = 25 m from a concert stage speaker during a sound check. When he is r1 from the speaker, the engineer registers a decibel level of β1 = 110 dB on his loudness meter. Randomized Variables r1 = 14 m r2 = 25 m β1 = 110 dB       Part (a) What is the intensity of the sound, I1, in watts per square meter, that is measured by the loudness meter when the engineer is a distance of r1 from the speaker? Numeric   : A numeric value is expected and not an expression. I1 = __________________________________________ Part (b) How much power P, in watts, is coming from the speaker during the sound check at distance r1? Numeric   : A numeric value is expected and not an expression. P = __________________________________________ Part (c) Assuming that the speaker output does not change between the two measurements at r1 and r2, what sound intensity level β2, in decibels, will the loudness meter report when the engineer is at a distance r2 from the speaker? Numeric   : A numeric value is expected and not an expression. β2 = __________________________________________
