Listening room compensation for wave field synthesis
نویسندگان
چکیده
Common room compensation algorithms are capable of dereverberating the listening room at some discrete points only. Outside these equalization points the sound quality is often even worse compared to the unequalized case. As wave £eld synthesis in principle allows to control the wave £eld within the listening area it can also be used to compensate for the re¤ections caused by the listening room in the complete listening area. We present a novel approach to listening room compensation which is based upon the theory of wave £eld synthesis and that results in a large compensated area.

Efficient Active Listening Room Compensation for Wave Field Synthesis
Wave field synthesis is an auralization technique which allows to control the entire wave field within the entire listening area. However, reflections in the listening room interfere with the auralized wave field and may impair the spatial reproduction. Active listening room compensation aims at reducing these impairments by using the playback system. Due to the high number of playback channels...
متن کاملActive listening room compensation for massive multichannel sound reproduction systems using wave-domain adaptive filtering.
The acoustic theory for multichannel sound reproduction systems usually assumes free-field conditions for the listening environment. However, their performance in real-world listening environments may be impaired by reflections at the walls. This impairment can be reduced by suitable compensation measures. For systems with many channels, active compensation is an option, since the compensating ...
متن کاملEvaluation of the Circular Harmonics Decomposition for WDAF-based Active Listening Room Compensation
The underlying theory of most massive multichannel spatial sound reproduction systems assumes ideal, e. g. free-field propagation characteristics in the listening room. The effects of non-ideal listening rooms can be reduced by active listening room compensation. A very efficient realization of such a system is given by wavedomain adaptive filtering. Here spatio-temporal signal transformations ...
متن کاملSimulation and Visualization of Room Compensation for Wave Field Synthesis with the Functional Transformation Method
Active room compensation based on wave field synthesis (WFS) has been recently introduced. So far, the verification of the compensation algorithms is only possible through elaborate acoustical measurements. Therefore, a new simulation method is applied that is based on the functional transformation method (FTM). Compared with other simulation techniques, the FTM provides several advantages that...
متن کاملSound Field Synthesis
Conventional multichannel audio reproduction systems for entertainment or communication are not capable of immersing a large number of listeners in a well defined sound field. A novel technique for this purpose is the so-called wave field synthesis. It is based on the principles of wave physics and suitable for an implementation with current multichannel audio hardand software components. A mul...
