Help please!!!! By how many decibels do you reduce the sound intensity level due to a source of sound if you double your distance from it? Assume that the waves expand spherically.
Homework Answers
sound intensity level is given by
L = 10 log(I/I0)
I is proportional to 1/r^2
so we have
L2 = L1 - 10 log(1/4)
L2 = L1 - 6
the intensity level decreases by 6 dB

The intensity due to a number of independent sound sources is the sum of the individual intensities. (a) When five quintuplets cry simultaneously, how many decibels greater is the sound intensity level than when a single quintuplet cries? (b) To increase the sound intensity level again by the same number of decibels as in part (a), how many more crying babies are required?

Sound waves at ultrasonic frequencies attenuate much faster than audible sound waves. The sound intensity level of a point source of ultrasonic sound waves is measured as 100 dB at a distance of 1.00 m from the source and 65 dB at 2.00 m. Assuming the waves spread in all directions, what is the attenuation coefficient alpha? [Answer in 1/m to within 5%]
