A trumpet creates a sound intensity level of
1.05 102 dB at a distance of 0.80 m.
(a) What is the sound intensity of a trumpet at this
distance?
W/m2
(b) What is the sound intensity of five trumpets at this
distance?
W/m2
(c) Find the sound intensity of five trumpets at the location of
the first row of an audience, 7.60 m away, assuming, for
simplicity, the sound energy propagates uniformly in all
directions.
W/m2
(d) Calculate the decibel level...
