Elevation localization is a timbral recognition task driven by resonant peaks

Evidence

It is important to realize that the localization cue we are talking about is really perceived timbre, and it is known from sound quality research discussed earlier in the book that listeners are very sensitive to resonant peaks and relatively insensitive to dips—acoustical interference dips are largely ignored. Underlying the untidy measured frequency-response curves is evidence of relatively stable resonances. Humans pay attention to, and are very sensitive to resonances, as they are significant timbral cues for all the sounds we are interested in: voices, musical instruments, etc. — Toole, Floyd E, Sound reproduction- the acoustics and…, 744
