Abstract
An audio system on a headset presents audio content via tissue conduction to an inner ear of a first ear of a user. The system monitors, via one or more sensors on the headset, data about the presented audio content. The one or more sensors including at least one sensor configured to capture data about the presented audio content at a second ear of the user. The system estimates array transfer functions (ATFs) associated with the data, and generates sound filters for the transducer array using the estimated ATFs. The system presents adjusted audio content based in part on the sound filters. The adjusted audio content has a damped region at the second ear such that the amplitude of the adjusted audio content at the first ear has a higher amplitude than at the second ear.
