Acoustic Calibration Tests of the 219 Projector.

Abstract

This report is intended to serve as an introduction to the 219 Moving Coil Projector and presents the measured response curves for the frequency range 50 - 200 Hz. Two different coil assemblies were tested and the measured response curves for both units are presented. Calibration of the projector's pressure sensor is also included to allow for accurate tow-depth determination. The projector's harmonic distortion was measured and its effect on a broadband signal presented. Finally, typical towing characteristics (tow-angle, tow-depth, and cable scope) are summarized for a nominal tow-speed of 3.5 knots.
