Cochlea's graded curvature effect on low frequency wavesCochlea's graded curvature effect on low frequency waves Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-082006enIn the ear, sound waves are processed by a membrane of graded mechanical properties that resides in the fluid-filled spiral cochlea. The role of stiffness grading as a Fourier analyzer is well known, but the role of the curvature has remained elusive. Here, we report that increasing curvature redistributes wave energy density towards the cochlea's outer wall, affecting the shape of waves propagating on the membrane, particularly in the region where low frequency sounds are processed.http://creativecommons.org/licenses/by/4.0/Physical Review Letters896 Manoussaki, D.
