Subject: The ear dynamically adapting frequency response From: Mark Fletcher <markfletcher22@xxxxxxxx> Date: Thu, 5 Feb 2009 11:47:51 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--_43ff9b3a-b3ce-4f05-b820-4bee091f304b_ Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Dear List =20 I am investigating the possibility that the ear dynamically adapts its freq= uency response dependant on environment=2C for example=2C to suppress noise= . My current thinking is that the mechanism for this adaptation is in the e= xpanding and contracting of the outer hair cells=2C restricting or exaggera= ting movement of the inner hair cells at different frequencies depending on= the stimuli. I would be grateful for any input anyone may have regarding t= his idea. =20 Thanks=2C =20 Mark _________________________________________________________________ Love Hotmail?=A0 Check out the new services from Windows Live!=20 http://clk.atdmt.com/UKM/go/132630768/direct/01/= --_43ff9b3a-b3ce-4f05-b820-4bee091f304b_ Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <html> <head> <style> .hmmessage P { margin:0px=3B padding:0px } body.hmmessage { font-size: 10pt=3B font-family:Verdana } </style> </head> <body class=3D'hmmessage'> <FONT size=3D3><FONT color=3D#000000><?xml:namespace prefix =3D o ns =3D "u= rn:schemas-microsoft-com:office:office" /><o:p> <P class=3DMsoNormal style=3D"MARGIN: 0cm 0cm 0pt"><FONT size=3D3><FONT fac= e=3D"Times New Roman">Dear List<o:p></o:p></FONT></FONT></P> <P class=3DMsoNormal style=3D"MARGIN: 0cm 0cm 0pt"><o:p><FONT face=3D"Times= New Roman" size=3D3> =3B</FONT></o:p></P> <P class=3DMsoNormal style=3D"MARGIN: 0cm 0cm 0pt"><FONT size=3D3><FONT fac= e=3D"Times New Roman">I am investigating the possibility that the ear dynam= ically adapts its frequency response dependant on environment=2C for exampl= e=2C to suppress noise.
