Acoustic navigation of a large‐aperture array

Acoustic Vector-Sensor Array Performance

Classical hydrophones measure pressure only, but acoustic vector-sensors also measure particle velocity. Velocity measurements can increase array gain and resolve ambiguities, but make vector-sensor arrays more difficult to analyze. This thesis derives a new set of useful performance measures for acoustic vector-sensor arrays. It characterizes the vector-sensor array beampattern with and withou...

Acoustic vector-sensor array processing

Existing theory yields useful performance criteria and processing techniques for acoustic pressure-sensor arrays. Acoustic vector-sensor arrays, which measure particle velocity and pressure, offer significant potential but require fundamental changes to algorithms and performance assessment. This thesis develops new analysis and processing techniques for acoustic vectorsensor arrays. First, the...

A Case Study of Auditory Navigation in Virtual Acoustic Environments

ABSTRACT We report results of an auditory navigation experiment. In auditory navigation sound is employed as a navigational aid in a virtual environment. In our experiment, the test task was to find a sound source in a dynamic virtual acoustic environment. In dynamic auralization the movements of the subject are taken into account in acoustic modeling of the room. We tested the effect of three ...
