Practical Test & Measurement: The Benefits of Using Structure-Borne Sound in Headset Signal Processing

This article looks at the practical test and measurement of bone conduction technology, as used in product development for headsets and in-ear devices. It showcases new possibilities for manufacturers to better evaluate device performance, since no appropriate test equipment and methods were commercially available until now. The approach, complements a Head-and-Torso Simulator (HATS) with an actuator capable of generating structure-borne sound in the artificial ear. This way, a realistic simulation of the human structure-borne voice signal for in-ear headsets is possible.. This article was originally published in audioXpress, January 2023.
