Homework Help: Wave and sound

    1. The problem statement, all variables and given/known data

    I read this question online.
    Estimate the length of your ear canal. 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 you hearing to be most sensitive? Explain why you can hear especially soft sounds just around this frequency.

    2. Relevant equations

    3. The attempt at a solution

    The human ear is most sensitive to the human speech bandwidth, which is from 500-4000 Hz, particularly at about 4,000 Hz.

    The ear canal can be treated as open pipe resonating at that frequency, and the length estimated by f=v/(2L).
