An investigation of sound radiation from the double bass using acoustical holography

Abstract

Studying radiation from musical instruments helps increase understanding and improve applications in auralizations, room acoustics, and microphone placement techniques. This work reviews a string bass's directivity measurements and demonstrates how numerical techniques such as spherical near-field acoustical holography enhance understanding of both the instrument's near-field and far-field radiation. The technique also allows calculation of the sound intensity field around the instrument, providing additional insights.
