ARMY - Bone conduction communication: Research progress and directions

This report is a follow-on report to previous US Army Research Laboratory (ARL) work that served as a summary of bone conduction research that had been conducted to 2007

and provided a foundation for future research studies. Since then several more bone conduction communication studies—both external and by ARL—

have been conducted to investigate the various characteristics of bone conduction communication systems. Progress has been made in understanding the nature of

bone conduction hearing and speech perception, bone conduction psychophysics, and bone conduction technology. A number of bone conduction devices have been developed

around the world, mostly outside of the United States; however, state-of-the-art bone conduction systems and bone conduction literature are not easily available due to

their commercial limitations, trade restrictions, and military applications. However, there is still a scarcity of information about bone conduction in open literature and in

trade magazines. In addition, information available in popular media outlets (e.g., TV, Internet, trade magazines) about the capabilities and physiological basis of

bone conduction communication is frequently far from scientific scrutiny and leads to misinformation. This report provides a comprehensive summary of the state of the

art in bone conduction communication technology applicable to the military. In addition, the report provides a list of current commercially available bone conduction devices,

including pictures and short descriptions of their basic specifications.
