Abstract: Calibration of a headset that uses bone conduction to provide audio content to a wearer is presented. A first tone of a plurality of tones that are at different frequencies is presented to the wearer via an air conduction transducer. A corresponding tone having a same frequency as the first tone is also presented to the wearer via a bone conduction (BC) transducer. The corresponding tone is adjusted such that a level of loudness is within a threshold range of a level of loudness of the first tone. An ear-canal sound pressure (ECSP) resulting from the first tone is recorded and a voltage applied to the BC transducer for generating the adjusted corresponding tone. An equalization filter is generated based in part on the ECSP and the voltage, the equalization filter for filtering an audio signal for presentation via the BC transducer.
