The Mathematics of the Cochlea

"According to the new model, as sound waves travel around the cochlea's spiral, the distribution of the energy that they carry changes: It becomes weaker along the inside wall while growing stronger and more concentrated along the outside wall. This shift is more pronounced in regions with highest curvature, which correspond to the low frequency regions of the ear and so amplify low frequency sounds."
