- Audio system 1 produces an intensity level of 87 dB and system 2 produces an intensity level 92 dB. The corresponding intensities in Wm2 are I, and 2 . Determine the ratio l½/l1. (express your answer in 3 decimal places)A trumpet creates a sound intensity level of 9.30 101 dB at a distance of 1.00 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, 7.00 m away, assuming, for simplicity, the sound energy propagates uniformly in all directions. W/m2(d) Calculate the decibel level of the five trumpets in the first row. dB(e) If the trumpets are being played in an outdoor auditorium, how far away, in theory, can their combined sound be heard? m(f) In practice such a sound could not be heard once the listener was 2-3 km away. Why can't the sound be heard at the distance found in part (e)? Hint: In a very quiet room the ambient sound intensity level is about 30 dBLoudness (L), in decibles (dB), of a sound of intensity I is defined to be L=10log( I/I0), where I0=10-12(W/M2) (watts per meter square) is the minimum intensity detectable by the human ear. A.) Find the loudness L, in decibles (dB), of a trombone given the intensity is 1010I0 B.) Find the intensity of a rock concert whose loudness is 115 decibles. C.)
