3. A trumpet creates a sound intensity level of 1.15*102 dB at a distance of 1.00 m.

I. What is the sound intensity of a trumpet at this distance?

II. What is the sound intensity of five trumpets at this distance?

III. Find the sound intensity of five trumpets at the location of the first row of an audience, 8.00 m away, assuming, for simplicity, the sound energy propagates uniformly in all directions.

IV. Calculate the decibel level of the five trumpets in the first row.

V. If the trumpets are being played in an outdoor auditorium, how far away, in theory, can their combined sound be heard?

VI. 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 the previous question? Hint: In a very quiet room the ambient sound intensity level is about 30dB.

Using a frequency-measuring lab device, I am to map out the sound intensity level distribution (dB) in a room (both with & without music playing) to create a 5x5 grid of 25 data points. Using the following data table of sound intensity level β(dB) and corresponding intensity I(W/m2), I also need to find the intensity to the nearest order of magnitude for the points on my sound intensity level maps. Here is the data table: Intensity levelβ(dB) Intensity I(W/m2) Example/effect...
