If a large housefly 3.0 m away from you makes a noise of
40.0 dB, what is the noise level of 1000 flies at that distance,
assuming interference has a negligible effect?
Assume the intensity of one housefly to be I. Then, the intensity of 1000 houseflies is 1000I. The variables that are to be used are noise level β and standard threshold intensity I0 . The expression for noise level is given by,
Sorry about that. What wasn’t helpful?
