Fast Adaptive Multichannel Equalization Identification and Control –(DANCE- FAME)
This subproject involves applications of Dynamic Acoustic Sensor Networks (DASN) for local control of noise, sound zones reproduction and generalized crosstalk cancellation on changing scenarios.
New sound field control strategies adapted to the environments where control or listening points may vary with time will be implemented and tested. Different control objectives will be considered at each listening or controlled area and they can dynamically change over time. It is intended that a different target sound field effect (cancellation, equalization, localized reproduction, etc.) could be selected by the user at each listening zone.
Classical techniques to characterize static indoor environments are not suitable enough due to the lack of knowledge about acoustic characteristics of the room, or because the environment and the position of microphones (listeners) and loudspeakers (sources) can be dynamic. Consequently, alternative approaches to spatial-temporal characterization of the room are necessary for indoor multi-zone and spatial audio applications in dynamic environments. Other aspects, such as information of the location of noise sources and obstacles and the coupling between the different loudspeakers and microphones of the Acoustic Sensor Network (ASN) need also to be addressed since they have great importance in the acoustic characterization of a room.
