Dear list, Thanks to David for an excellent lecture on pitch-height mapping.
To add to the point of a perceptual basis for the pitch-height description I would like to add that low frequencies probably are perceived as lower in the body due to the low-frequency resonance of the lungs, high frequencies
higher because of resonances in the smaller air cavities in the head ( comparable to the ‘head voice/chest voice’ distinction of singers). These effects are partly non-auditory and are not seen in the HRTFs.
In the example with the congenitally blind persons it would be nice to know whether they still perceived low-frequency sounds as lower in the body than high-frequency sounds.
