Evaluation of Speech Intelligibility through a Bone Conduction Stimulator

Abstract

The intelligibility of speech, delivered via a bone-conduction transducer, was measured under simulated combat vehicle noise conditions and compared with the same measurements made with a conventional, air-conduction system. The measurements were made for conditions in which the ear canals were open and in which they were occluded with protective earplugs. The use of bone- conduction system led to a 25.3-dB improvement over the conventional, air- conduction system. Keywords: Bone conduction; Speech intelligibility; Occlusion effect; Voice communications.
