Auditory models that extract distance cues from ear signals remain an open research direction

Evidence

The hearing mechanisms which are used in distance perception are not known in general. For example, it is not known precisely how the perceived distance is extracted from the effect of the room response in the ear canal signals. A research topic for auditory modelling would thus be to form signal-driven auditory models that measure the cues for distance perception and then combine them to form the final perception of distance. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1533
