__HOMEWORK ASSIGNMENT #6 Due Friday March 4, 2005__

RMW refers to the textbook *The Science of Sound, 3rd
Edition,* by T.D. Rossing, F.R. Moore, & P.A. Wheeler

- RMW, page 119, exercises 2 and 4.
- In class we talked about how the anatomical transfer function (ATF) assists in eliminating front-back-overhead confusion in localizing sounds. Is the ATF equally effective regardless of sound frequency, more effective at higher frequencies, or more effective at lower frequencies? Explain your reasoning using physical principles.
- If you go to low enough levels, the JND ("Just Noticeable Difference") in sound level may become as large as 2 dB. Under those conditions, what is the minimum detectable change in intensity, expressed as a percentage?
- RMW, page 715, exercise 2.

Please send any comments to Jack Hughes, jph@physics.rutgers.edu.
