Homework Help: Physics

Posted by HelpPlease on Sunday, December 5, 2010 at 9:30pm.

If a large housefly 3 m away from you makes a noise of 43 dB, what is the noise level of 1200 flies at that distance, assuming interference has a negligible effect?

Noise level of 1200 flies = ??dB


HELP: Using the formula for decibels and the given information, you can calculate the ratio I / I0 for 1 fly.

HELP: If you assume that 1200 flies make 1200 times as much noise as 1 fly, what is I / I0 for 1200 flies?
