This site contains sound examples, color figures, animations, links and other materials to support the study of auditory phenomena.
This youtube video shows a husky dog named "Mishka", exchanging some surprisingly verbal declarations of love with her owners.
Here another animation showing the mechanical response of the basilar membrane, but this time the incoming sound is not the sum of two sine waves, but a single "ideal impulse", or click.
The top trace shows the click stimulus. Think of the click as travelling through air, but also impinging on the cochlea at time zero. The bottom trace shows the basilar membrane, with distance from the basal end on the x-axis.
