Typo in the video (I think, not an anatomist), it's "basilar" membrane, not "vasilar." Awesome video though, I wish my speech processing professor had used that

Typo in the video (I think, not an anatomist), it's "basilar" membrane, not "vasilar." Awesome video though, I wish my speech processing professor had used that instead of teaching hearing like a filterbank, even if that is how we needed to understand it. Another weird thing about hearing: the hairs that vibrate aren't just tuned to particular frequencies, they actually vibrate over a range, and the response isn't symmetric (although iirc, part of that is from the fact the hairs are mechanically coupled). That's why low frequency noise masks high frequency noise more than vice versa, which is exploited in lossy codecs (if there's low frequency energy, you don't need high frequency energy that it masks).
