Studies on a Spatialized Audio Interface for Sonar

Abstract

This report summarizes an investigation of the application of a spatialized audio interface over headphones for use in submarine sonar operations and training that was performed in the period from December 2007 through September 2010 as part of a larger ONR study led by the Johns Hopkins University Applied Research Laboratory with engineering support from the Naval Undersea Warfare Center, Newport. NSMRL, with collaborators at University of Michigan and New York University, provided applied binaural research on human auditory processing of spatialized (or 3D) audio over headphones. A comprehensive summary is presented of a series of experiments in six focus areas quantifying human listener performance as a function of variations in critical parameters of this new audio interface. Recomendations are also made for further study in four of the focus areas where significant performance improvement may be gained.
