Source distribution perception is hard because ear-canal signals sum before analysis
Evidence
Binaural techniques are loosely defined to be methods that aim to reproduce accurately ear canal signals recorded in a real acoustic scenario with a real subject, or to reproduce ear canal signals which would occur in a virtual world. This is done by recording sound from ear canals or by utilizing measured or modelled head-related transfer functions (HRTFs) and acoustic modelling of listening spaces. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1916 (
