Abstract

The human auditory system is more accurate at localizing sounds in front than at lateral, rear, and elevated directions. In virtual reality applications, where Ambisonic audio is presented to the user binaurally (over headphones) in conjunction with a head-mounted display, it is imperative that audio in the frontal direction is as accurate as possible. This paper presents a method for improving frontal high frequency reproduction of binaural Ambisonic rendering through a novel adaptation of the diffuse-field equalization technique to exploit the non-uniform directional sensitivity of human hearing. The method is evaluated via spectral difference and a height localization model, and results show improved frontal reproduction at the expense of lateral fidelity.
