Sound field control for multiple listener virtual imaging

ViSQOL: The Virtual Speech Quality Objective Listener

A model of human speech quality perception has been developed to provide an objective measure for predicting subjective quality assessments. The Virtual Speech Quality Objective Listener (ViSQOL) model is a signal based full reference metric that uses a spectro-temporal measure of similarity between a reference and a test speech signal. This paper describes the algorithm and compares the result...

Active noise control at a virtual acoustic energy density sensor in a three-dimensional sound field

A common problem in local active noise control is that the zone of quiet centered at the physical microphone is too small to extend to the desired location of attenuation, such as an observer’s ear. The physical microphone must therefore be placed at the desired location of attenuation, which is often inconvenient. Virtual microphones overcome this by shifting the zone of quiet away from the ph...

Sound Field Control in the Automotive Environment

Local Sound Field Synthesis by Virtual Secondary Sources

Sound field synthesis techniques like Wave Field Synthesis and Higher-Order Ambisonics aim at the physical synthesis of a desired sound field over an extended listening area. However, for practical setups the accuracy up to which the desired sound field can be synthesized over an extended area is limited. For certain applications it is desirable to limit the spatial extent of the listening area...

Virtual 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 ...
