Simulating autophony with auralized oral-binaural room impulse responses

摘要

This paper presents a method for simulating the sound that one hears from one's own voice in a room acoustic environment. Impulse responses from the mouth to the two ears of the same head are auralized within a computer-modeled room in ODEON; using higher-order ambisonics for modelling the directivity pattern of an anthropomorphic head and torso. These binaural room impulse responses, which can be measured for all possible head movements, are input into a mixed-reality room acoustic simulation system for talking-listeners. With the system, 'presence' in a room environment different from the one in which one is physically present is created in real-time for voice related tasks.
