Re: Traveling waves or resonance?
I apologize for incomplete links:
For a comparison, look into pertaining figures at
The real-valued ('natural') spectrogram does of course not yet consider the
effect of cochlear amplifier on threshold. It merely ascribes what has perhaps
wrongly been attributed to wave mechanics so far. According to findings of
Geoffrey Manley who pointed to the fact that frequeny ratios are almost equal
for very different animals, I tend to see critical bandwidth also controlled by
a fully spread cochlear amplifier, maybe via the two spatial extensions of the
standing traveling wave.
The real-valued spectrogram may nonetheless support imagination. It illustrates
how responses to rarefaction and condensation differ from each other.
