Subject: Re: Circuit model of the middle ear - searching for publicly avaliable models From: Sunil Puria <puria@xxxxxxxx> Date: Fri, 9 Jan 2015 21:56:32 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--Apple-Mail=_7D0B1B9E-7F2F-44BC-87C7-E0EACD2F4C38 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=iso-8859-1 Dear Felipe, you might be interested in following circuit model paper: O'Connor KN, Puria S (2008) Middle-ear circuit model parameters based on = a population of human ears. The Journal of the Acoustical Society of = America 123:197-211. http://www.ncbi.nlm.nih.gov/pubmed/18177151 I am happy to share the MATLAB implementation of the model. We have also = implemented a finite element model of the human middle ear, which has = been a challenge. Happy to discuss details offline.
