AW: the seven wonders of hearing
Hello Matt and List,
Finally I can give a fairly short answer: Of your seven
wonders, I strongly prefer Nr. 7, active TW -- but only
if the active part of the TW is restricted to a short
x_b-region (typically 0.4 mm in gerbils, and not 4 mm
as I wrote 45 minutes ago!) on the basal slope of the

Betreff: the seven wonders of hearing
In no particular order :
a] Oscillators: Van Der Pol type oscillators, which I
believe began with Johannesma 
b] Squirting wave: Andrew Bell's Organ of Corti squirting
c] Dual resonance: Martin Braun's dual resonance
d] Feedback amp.: Zwicker's feedback amplifier 
e] Hopf amplifier: Hopf bifurcation augmenting the travelling
f] Active TW: Active travelling wave amplifiers - of which I
believe there are many, I reference only one 
g] Active CW: Active compression wave amplifier. Of which
I have seen no complete models - as of yet.
