The Southeast Alaska Acoustic Measurement Facility (SEAFAC) is currently the most advanced acoustic testing field for submarines. It is also the most important acoustic testing area of the United States in Pacific Ocean. It provides the capability to perform noise monitoring, measurement and evaluation for ships, to determine the sources of radiation noise, to assess vulnerability, and to develop quieting measures. SEAFAC is also capable of supporting submarine target strength measurements. In this paper, the history, main facility and fuction of SEAFAC are introduced and studied. It may be helpful for building acoustic testing field in China.

Analysis of Facilities of Norwegian Acoustic Testing Field in Heggernes
LIU Xing-zhang;CHEN Tao
   2011, 31 (5): 161-164.   DOI: 10.3969/j.issn.1006-1355-2011.05.038

Testing of underwater radiation noise of submarines using acoustic testing field is one of the important measures for improving the submarine’s silence in some developed countries. The Norwegian acoustic testing field in Heggernes is the most important testing field for measuring underwater noise of submarines of the members of NATO such as Germany, Holland, Demark, Norway and so on. In this paper, the characters of location and main facilities of the testing field are introduced. The advantages and disadvantages of the testing field construction in bay area are analyzed. Roles of the static testing field and the dynamic ranging to the testing field construction are studied. This discussion may be helpful for construction of acoustic testing field in our country.
