What is the fundamental frequency for human ear sensitivity?

[frenchy7322]

The human ear canal is about 2.8 cm long, if it is regarded as a tube that is open at one end and closed at the eardrum, what is the fundamental freq. around which we would expect hearing to be most sensitive? Take the speed of sound to be 340 m/s.

Is it:

wave speed = frequency x wave length

340 = f x 2.8 etc.? Not real sure. Thanks for any help in advance.

Think about the wavelength of the fundamental if the tube is closed at one end and it is 2.8cm long.
