The human ear canal is, on average, 2.5cm2.5cm long and aids in hearing by acting like a resonant cavity that is closed on one end and open on the other. The length of the ear canal is partially responsible for our sensitivities to certain frequencies. Use 340m/s for the speed of sound when performing the following calculations.
Required:
a. What is the first resonant frequency?
b. What is the wavelength at second resonance?
c. How does the first resonant frequency change if the ear canal is full of water?
