the seven wonders of hearing


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.
