Perceptual Assessment of Delay Accuracy and Loudspeaker Misplacement in Wave Field Synthesis

The implementation of simple virtual source models like plane and spherical waves in wave field synthesis employs delays which are applied to the input signals. We present a formal experiment evaluating the perceptual consequences of different accuracies of these delays. Closely related to the question of delay accuracy is the accuracy of the loudspeaker positioning. The second part of the presented experiment investigates the perceptual consequences of improperly placed loudspeakers. Dynamic binaural room impulse response based simulations of a real loudspeaker array are employed and a static audio scene setup is considered.
