Combining artificial and natural background noise in personal audio systems
Combining artificial and natural background noise in personal audio systems
Personal audio systems are designed to deliver spatially separated regions of audio to individual listeners. This paper presents a method for improving the privacy of such systems by predicting speech intelligibility in the bright and dark sound zones. A synthetic masking signal reproduced in the dark zone is adapted to provide sufficient privacy and reduce the potential for annoyance by responding to changes in ambient noise. Results from a simulated personal audio system show that the inclusion of artificial masking can improve the performance of an array in terms of intelligibility contrast.

Abstract
Personal audio systems are designed to deliver spatially separated regions of audio to individual listeners. This paper presents a method for improving the privacy of such systems by predicting speech intelligibility in the bright and dark sound zones. A synthetic masking signal reproduced in the dark zone is adapted to provide sufficient privacy and reduce the potential for annoyance by responding to changes in ambient noise. Results from a simulated personal audio system show that the inclusion of artificial masking can improve the performance of an array in terms of intelligibility contrast.
