An Acoustic Monitoring System for the Vibroseis Low-Frequency Underwater Acoustic Source

Abstract

One problem normally associated with the use of Low-frequency, high- power underwater acoustic sources is the ability to accurately monitor the generated sound pressure level. The USRD was tasked by the Office of Naval Research to design, fabricate, and install an acoustic monitoring system for a large hydraulically actuated source, the VIBROSEIS system. The monitoring transducers and the associated calibration system were designed to operate in the 5- to 225-Hz frequency range and to minimize several problems associated with the particular source. the system was installed, calibrated at sea, and performed satisfactorily during the ocean exercise.
