Perceptually Optimized Loudspeaker Selection for the Creation of Personal Sound Zones
Sound field control methods can be used to create multiple zones of audio in the same room. Separation achieved by such systems has classically been evaluated using physical metrics including acoustic contrast and target-to-interferer ratio (TIR). However, to optimise the experience for a listener it is desirable to consider perceptual factors. A search procedure was used to select 5 loudspeakers for production of 2 sound zones using acoustic contrast control. Comparisons were made between searches driven by physical (programme-independent TIR) and perceptual (distraction predictions from a statistical model) cost func- tions. Performance was evaluated on TIR and predicted distraction in addition to subjective ratings. The perceptual cost function showed some bene ts over physical optimisation, although the model used needs further work.
