As I recall, the interaction between pitch and intensity applies only to pure tones. For harmonic complex tones, the perception of pitch is almost exclusively dependent upon the fundamental frequency. However, it is very common for the non-musically trained (such as myself) to confuse pitch and brightness of timbre. One would certainly expect an opening eustacian tube to alter the timbre of sounds through a change in the middle-ear transfer function. Is there anyone musically trained who is able to confirm that this is specifically a change in pitch? Otherwise, I prefer a simple timbre- change explanation. John.
