Optimisation of personal audio systems for intelligibility contrast
Optimisation of personal audio systems for intelligibility contrast
Personal audio systems are designed to deliver spatially separated regions of audio to individual listeners. This paper demonstrates a method of personal audio system design which provides a level of contrast in the perceived speech intelligibility between bright and dark audio zones. Limitations in array directivity which would lead to a loss of privacy are overcome by reproducing a synthetic masking signal in the dark zone. This signal is optimised to provide effective masking whilst remaining subjectively pleasant to listeners. Results of this optimisation from a simulated personal audio system are presented.

Abstract
Personal audio systems are designed to deliver spatially separated regions of audio to individual listeners. This paper demonstrates a method of personal audio system design which provides a level of contrast in the perceived speech intelligibility between bright and dark audio zones. Limitations in array directivity which would lead to a loss of privacy are overcome by reproducing a synthetic masking signal in the dark zone. This signal is optimised to provide effective masking whilst remaining subjectively pleasant to listeners. Results of this optimisation from a simulated personal audio system are presented.
