Interesting. But I would argue that there is another, far more straightforward explanation:
The auditory nervous system is highly nonlinear. Nonlinear responses arise both in the cochlea
and in the central auditory system. In humans, auditory brainstem recordings show nonlinear population
responses to combinations of pure tones, and to musical intervals composed of complex tones.
In nonlinear systems, gain changes the nature of the response qualitatively. The stronger the
input, the more nonlinear resonances (harmonics, subharmonics, combination tones and
integer ratios) appear.
According to this reasoning, louder music is not just more of the same thing … it is a qualitatively
different experience. Louder music should literally lead to different patterns of resonance in the

Old guys with undamaged hair cells have the advantage that they can fully
enjoy classical tonal music with its change from dissonant to consonant

change is due to the presence or absence of beats generated by pairs of
partial tones of almost equal frequencies. These partials tend to be
soft, and their frequencies tend to be high.
Do you know the answer to the opposite: why is rock music more enjoyable
loud? I think that it would be important to understand.
