Bone Conduction Intelligibility: Headset Comparison Study

摘要

Air conduction (AC) communication technology tends to impede situational awareness because it requires one or both ears to be covered. Bone conduction (BC) communication technology allows users to maintain radio communication without severely compromising situational awareness. This study compares four BC headsets using a military speech intelligibility test. The tests were administered within three background noise level conditions. Twenty undergraduates participated in this study. Significant performance differences between the three noise levels were found. No significant differences between the headsets or headsets-noise level interactions were identified. Usability survey data indicate the BC headsets are comfortable and easy to position.
