Abstract

Accurately measuring the marine ambient noise is the premise for high resolution underwater acoustic detection, and sound pressure is a key parameter to certain the marine ambient noise spectrum. Scalar hydrophone is taken here to measure the offshore ambient noise for a long-term in certain offshore field. By taking laser interferometry technology, the accuracy of hydrophone can be achieved to the laser wavelength level. Experimental results show that this hydrophone has good measuring accuracy of sound pressure signal that up to 6.6 × 10-3 Pa, and the distribution of noise spectrum in experimental area is 88 ~ 92 dB with a good frequency response capability. Comparison results with normal mode hybrid model would further validate the accuracy of this experimental data.
