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&#8217;s outer wall, affecting the shape of waves propagating on the membrane, particularly in the region where low frequency sounds are processed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mathematicians at Vanderbilt University have created a mathematical model of the cochlea and use the model to show that the spiral shape acts to enhance <span class=\"ellipsis\">&hellip;<\/span> <span class=\"entry-more-link-wrapper\"><a href=\"https:\/\/www.noiseboard.com\/?p=300\" class=\"entry-more-link entry-more-link-excerpt btn btn-primary\"><span>Read More<\/span><\/a><\/span><\/p>\n","protected":false},"author":24,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-300","post","type-post","status-publish","format-standard","hentry","category-news"],"_links":{"self":[{"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=\/wp\/v2\/posts\/300","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=\/wp\/v2\/users\/24"}],"replies":[{"embeddable":true,"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=300"}],"version-history":[{"count":2,"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=\/wp\/v2\/posts\/300\/revisions"}],"predecessor-version":[{"id":1788,"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=\/wp\/v2\/posts\/300\/revisions\/1788"}],"wp:attachment":[{"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=300"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=300"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.noiseboard.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=300"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
