Objective evaluation of a three-dimensional sound field reproduction system
We present the results of an empirical evaluation of a three-dimensional sound field reproduction system consisting of 32 loudspeakers installed in a hemi-anechoic room at the University of Sydney. This loudspeaker arrangement allows up to third-order, two-dimensional, and fourth-order, three-dimensional Higher Order Ambisonic (HOA) reproduction of sound fields. The ability of this system to re...
متن کاملVirtual Reality System with Integrated Sound Field Simulation and Reproduction
A real-time audio rendering system is introduced which combines a full room-specific simulation, dynamic crosstalk cancellation, and multitrack binaural synthesis for virtual acoustical imaging. The system is applicable for any room shape (normal, long, flat, coupled), independent of the a priori assumption of a diffuse sound field. This provides the possibility of simulating indoor or outdoor ...
متن کاملRobust reproduction of sound zones with local sound orientation.
Pressure matching (PM) and planarity control (PC) methods can be used to reproduce local sound with a certain orientation at the listening zone, while suppressing the sound energy at the quiet zone. In this letter, regularized PM and PC, incorporating coarse error estimation, are introduced to increase the robustness in non-ideal reproduction scenarios. Facilitated by this, the interaction betw...
متن کاملTowards a Theory for Arbitrarily Shaped Sound Field Reproduction Systems
The simple source approach predicts that a distribution of appropriately driven loudspeakers (secondary sources) enclosing a given listening area is suitable for the physical recreation of any desired exterior virtual sound field within that listening area. A specific class of sound reproduction approaches (e.g. higher-order Ambisonics) is based upon the explicit solution of the simple source f...
متن کاملSpatial Sound Reproduction with Wave Field Synthesis
Stereophonic spatial sound reproduction systems with two, five, or more channels are designed for a certain listener position and work well in its vicinity, the so called sweet spot. For listeners at other positions, the quality of the spatial reproduction may be degraded. This contribution describes an advanced spatial reproduction technique called wave field synthesis. It is based on a physic...
