Abstract
The goal of this research is to develop a comprehensive biomechanical simulation model of a full human head which includes internal anatomical features down to the minute structure of a human cochlea for accurate representation of full sound pathways to the human cochlea, including bone conduction. Such a model will provide simulation of noise energy that gets transmitted to the basilar membrane in the cochlea, thereby providing prediction of quantities that have only been possible with psychoacoustic test approaches. This enables more accurate prediction of hearing protection device (HPD) effectiveness, thereby providing a powerful tool for research and development in this area. The full head auditory system model developed under this unique program is expected to provide answers to long-standing questions in the field of hearing protection, as well as general human auditory mechanics, thereby providing necessary theoretical foundations for the development of next-generation hearing protection programs and technologies for the military.
