Spatially extended sound equalisation in rooms at low frequencies

    Research output: Book/ReportBookResearchpeer-review


    The thesis describes the results of a theoretical and experimental study of equalisation of the sound field in a room. The theoretical study is based on computer simulations, carried out both in the frequency domain and in the time domain with account taken of the causality of the control filters. The influence of the number of sources and their position, the number of error sensors and their positions, the frequency range etc. is examined. Among the conclusions can be mentioned that the size of the equalised area can be maximised and the number of loudspeakers can be minimised if the sound field that is generated is a propagating plane wave.
