Hearing Protection for High-Noise Environments. Part 1

Abstract

Report developed under STTR contract for topic AFO6-T035. The objective of our effort was to develop powerful soffware tools and to perform high fidelity simulation which would allow identification and understanding of relevant bioacoustic and psychoacoustic mechanisms responsible for the transmission of acoustic energy through non-airborne pathways to the cochlea. As the main achievements of our Phase I work we consider: - development of a set of algorithms (including non-lossy, error-controlled matrix compression techniques) for general, i.e., variable-density, volumetric equations of acoustics, and development of a solution technique overcoming ill-conditioning difficulties arising in large density contrast problems.
