... The sensitivity of the human ear for frequencies around 3 kHz can be understood in terms of resonance in the ear canal. The canal can be thought of as a tube with one open and one closed end, so standing waves in this tube have a wavelength in the fundamental mode equal to 4L, where L is the length ...
