Auditory elevation calibration requires visual confirmation of sound sources

Evidence

The results show that the accuracy of perception of elevation degrades in directions outside the field of vision. This is in line with the fact that subjects continuously adapt to their spectral cues, as discussed in Section 12.3.4. The result also suggests that adaptation can occur only if the sources are visible. Using vision as the reference for adaptation of directional hearing is a viable option, as vision is the most accurate method to measure the direction of a sound source for adaptation. Furthermore, the auditory and visual pathways meet at a relatively low level in the brain, as discussed in Section 7.7.1, which could facilitate such adaptation. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1482
