Offshore Marine Ambient Noise Measurement Study Based on Laser Interferometer Hydrophone HUA Zhili1,2,a, LI Lei1,2 and ZHOU Zhonghai1,2 1 Shandong Provincial Key Laboratory of Ocean Environmental Monitoring Technology，Qingdao, China 2 Institute of Oceanographic Instrumentation，Shandong Academy of Sciences，Qingdao, China ahua_zhili@163.com Keywords: Marine Acoustics, Marine Ambient Noise, Hydrophone, Michelson Interferometry Abstract.
Error analysis shows that the vibrating membrane is the main source of the sound pressure error, which can be eliminated to a certain extent by a vibrating membrane materials selection.
Error analysis of sound pressure measuring is present in part 3, in which proper material selection and optical path design can be taken as an effective way for the error reduction.
The work was supported by International Science & Technology Cooperation Program of China under Grant No. 2014DFR60490.

The results showed that the concentration of calcium carbonate had a great influence on metal materials, but not a major factor affecting the induction period of non-metallic materials; the average amount of dirt and the standard deviation is inversely proportional to the concentration of calcium carbonate.
