Chapter 17, Problem 51PE
Calculate the first overtone in an ear canal, which resonates like a 2.40−cm−long tube closed at one end, by taking air temperature to be 37.0°C. Is the ear particularly sensitive to such a frequency? (The resonances at the ear canal are complicated by its nonuniform shape, which we shall ignore.)

Calculate the first overtone in an ear canal, which resonates like a 2.40-cm-long tube closed at one end, by taking air temperature to be 37.0ºC . Is the ear particularly sensitive to such a frequency? (The resonances of the earcanal are complicated by its nonuniform shape, which we shall ignore.)
An FM communication system has a sensitivity of 4 kHz/V. How much deviation (in Hz) does it produce with a sine wave input of 19.66 Vpeak at a frequency of 4.8 kHz?
Suppose you want an oboe to produce a fundamental frequency of 106 Hz (which is below the range of a typical oboe) on a day when the temperature is 14.5°C.
If you treat the oboe as a perfect air column which is open at both ends, how long, in meters, should the oboe be?
