Wave and sound

  1. Nov 16, 2007 #1
    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.

    A closed end is a node and an open end is an anti-node. What fraction of a wavelength fits between an anti-node and a node? Multiply by the inverse of that fraction to get the full wavelength and then translate that into a frequency.
