Abstract

The characteristics of a reproduced sound ?eld in acoustic augmented reality (AR) are crucial to present a virtual sound source with realism for the listener. An effective approach is to add the reverberation characteristics of the reproduction ?eld. Herein the reverberant components from impulse responses measured at a single point in a room are extracted and added to the listener’s individual head-related transfer function (HRTF). It can be regarded as a synthesis of the equivalent of a binaural room transfer function (BRTF) of the ?eld where the listener is. The effectiveness of the proposed method is veri?ed via a comparison experiment between a real sound source and a virtual sound source. The proposed method has the same effect as the listener’s BRTF. Additionally, neither the sound source position nor individualization is necessary to acquire the reverberation characteristics.
