Abstract

This study looked at the intelligibility of vocal signals previously recorded via bone conduction (BC) microphones. This research sought to explore the clarity of BC microphone signals transmitted through predetermined locations on the skull. The positioning of the BC microphone was distributed throughout eight different locations, where each location was deemed significant through prior studies. A total number of twelve ERAU college students were randomly selected to participate in the study. Since the study utilized a with-in subject design, each participant was exposed to recording from each of the BC microphone locations. The recording consisted of ten scripted words with each word presented to the participant using both male and female voices. The signals were transmitted to the participant through a BC vibrator headset. This study’s results will provide evidence on whether or not BC communication devices can be used as an effective means of communication.
