Textbook Question
Chapter 14, Problem 36P
Do not stick anything into your ear! Estimate the length of your ear canal, from its opening at the external ear to the eardrum. If you regard the canal as a narrow tube that is open at one end and closed at the other, at approximately what fundamental frequency would you expect your hearing to be most sensitive? Explain why you can hear especially soft sounds just around this frequency.

Resonances of the ear canal lead to increased sensitivity of hearing, as we've seen. Dogs have a much
longer ear canal-5.2 cm-than humans. What are the two lowest frequencies at which dogs have an
increase in sensitivity? The speed of sound in the warm air of the ear is 350 m/s.
A 1700 Hz, 3400 Hz
B. 1700Hz, 5100Hz
C. 3400 Hz, 6800 Hz
D. 3400 Hz, 1 0,200 Hz
Sound waves travel at roughly 340 m/s at room temperature. The minimum hearing range of a human is 20Hz. a) What is the wavelength of this wave? b) Could this wavelength fit inside the dimensions of Room 411( room dimensions are roughly 11.5 m x 8.7 m)? Justify your answer with sound reasoning (pun intended :-))
Ralph's ear canal is 2.67 cm long. If it is regarded as a tube that is open at one end and closed at the eardrum, what is the fundamental frequency around which we would expect hearing to be most sensitive? Use 345 m/s for the speed of sound in air.
