The decibel scale is a logarithmic scale for measuring the sound intensity level. Because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in W/m2 changes by a multiplicative factor. The number of decibels increases by 10 for a factor of 10 increase in intensity. The general formula for the sound intensity level, in decibels, corresponding to intensity I is β=10log(II0)dB, where I0 is a reference intensity. For sound waves, I0 is taken...

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...
