Perception of Reconstructed Sound-Fields: The Dirty Little Secret

Document Thumbnail

This paper presents results of a pilot study regarding the perception of reconstructed sound-fields by a pairwise preference test between reproductions based upon perceptually versus mathematically posed objectives. These preliminary results suggest that increased calibration and accuracy, including loudspeaker signal time-alignment, was found to produce spatial imagery that is less preferred. Therefore a series of experiments have been launched to investigate the impact of reconstruction accuracy on user experience by selectively degrading spatial fidelity over the reproduction area. The dirty little secret, that higher accuracy does not produce preferred results, may well be revealed through such experimental studies.
