Subject: the seven wonders of hearing From: Matt Flax <flatmax@xxxxxxxx> Date: Sun, 21 Oct 2007 03:15:36 +1000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hello, After our discussion last week, I have made a new list of possible physiological Cochlea Amplifiers (some of these are weakly physiologically based). I currently count seven. Can any one reference - in a completely published model - the seventh ? Can anyone think of other physiologically based CAs to add to the list ? If so then please add them and change the subject line. In no particular order : a] Oscillators : Van Der Pol type oscillators, which I believe began with Johannesma [1] b] Squirting wave : Andrew Bell's Organ of Corti squirting amplifier [2] c] Dual resonance : Martin Braun's dual resonance model [3] d] Feedback amp. : Zwicker's feedback amplifier [4] e] Hopf amplifier : Hopf bifurcation augmenting the travelling wave [5,6] f] Active TW : Active travelling wave amplifiers - of which I believe there are many, I reference only one [7] g] Active CW : Active compression wave amplifier. Of which I have seen no complete models - as of yet. thanks Matt [1] @xxxxxxxx{Johannesma:1980, author = {Johannesma, P.I.M.}, title = {Narrow Band Filters and Active Resonators}, booktitle = {Psychophysical, physiological and behavioural studies in hearing}, publisher = {Delft University Press: Delft}, year = {1980}, editor = {van der Brink, G. and Bilsen, F.A.}, pages = {62-63} } [2] @xxxxxxxx{bell:2004, author = {Bell, A. and Fletcher, N.H.}, title = {{The cochlear amplifier as a standing wave: "Squirting" waves between rows of outer hair cells?}}, journal = {The Journal of the Acoustical Society of America}, year = {2004}, volume = {116}, pages = {1016}, publisher = {ASA} } [3] @xxxxxxxx{braun:1994, title={{Tuned hair cells for hearing, but tuned basilar membrane for overload protection: evidence from dolphins, bats, and desert rodents}}, author={BRAUN, M.}, journal={Hearing research}, volume={78}, number={1}, pages={98--114}, year={1994}, publisher={Elsevier} } [4] @xxxxxxxx{Zwicker:1986a, author = {Zwicker, E.}, title = {A hardware cochlear nonlinear preprocessing model with active feedback}, journal = {Journal of the Acoustical Society of America}, year = {1986}, volume = {80}, pages = {146-153}, number = {1}, month = {July} } [5] @xxxxxxxx{duke:2003, author = {Duke, T. and J{\"u}licher, F.}, title = {{Active Traveling Wave in the Cochlea}}, journal = {Physical Review Letters}, year = {2003}, volume = {90}, pages = {158101}, number = {15}, publisher = {APS} } [6] @xxxxxxxx{magnasco:2003, author = {Magnasco, M.O.}, title = {{A Wave Traveling over a Hopf Instability Shapes the Cochlear Tuning Curve}}, journal = {Physical Review Letters}, year = {2003}, volume = {90}, pages = {58101}, number = {5}, publisher = {APS} } [7] @xxxxxxxx{neely:1983, title={{An active cochlear model showing sharp tuning and high sensitivity.}}, author={Neely, ST and Kim, DO}, journal={Hearing Research}, volume={9}, number={2}, pages={123--30}, year={1983} } -- ,dPYb,,dPYb, I8 IP'`YbIP'`Yb I8 http://www.flatmaxstudios.com/ I8 8II8 8I 88888888 http://www.flatmax.org I8 8'I8 8' I8 I8 dP I8 dP ,gggg,gg I8 ,ggg,,ggg,,ggg, ,gggg,gg ,gg, ,gg I8dP I8dP dP" "Y8I I8 ,8" "8P" "8P" "8, dP" "Y8I d8""8b,dP" I8P I8P i8' ,8I ,I8, I8 8I 8I 8I i8' ,8I dP ,88" ,d8b,_,d8b,_,d8, ,d8b,d88b,dP 8I 8I Yb,d8, ,d8b,dP ,dP"Y8, PI8"888P'"Y8P"Y8888P"`Y8P""Y8P' 8I 8I `YP"Y8888P"`Y8" dP" "Y8 I8 `8, I8 `8, I8 8I Public Projects : I8 8I http://sourceforge.net/search/?type_of_search=soft&words=mffm I8, ,8' http://www.psysound.org "Y8P'
