Abstract

To study human auditory perception in realistic environments, loudspeakerbased reproduction techniques have recently become state-of-the-art. To evaluate the accuracy of a simulation-based room auralization of a small room, objective measures were evaluated. In particular: - early-decay time (EDT) & reverberation time (T20, T30); - clarity (C7, C50, C80); - interaural cross-correlation (IACC); - speech transmission index (STI); - direct-to-reverberant ratio (DRR). Impulse responses (IRs) were measured in an IEC listening room. The room was then modeled in the room acoustics software ODEON, and the same objective measures were evaluated for auralized versions of the playback room. The auralizations were realized using higher-order ambisonics (HOA), mixed-order ambisonics (MOA), and a nearest-loudspeaker method (NL) and reproduced in a virtual sound environment.
