I've scanned my psychoacoustics and audiology texts, but can't find data on this. Is there a detailed review of known mechanisms for audio induced hearing loss mechanisms available somewhere? I know the basics (roughly), but I'm more interested in processes at inner ear level, esp. as it relates to intensity (dB) vs subjective loudness (phon). Or to put it in other words, does the frequency distribution of a sound wave have a significant impact on the actual hearing damage induced (at different intensities), or does sound wave distribution merely affect perception of loudness. That is, how are loudness perception AND actual hearing damage (loss) correlated at various intensity levels when the stimuli waveform is changed (triangle, sine, square, etc)? I can imagine it's difficult to test this on actual humans, but maybe some kind of epidemological data could exist, no? Any references on this would be very welcome.
