A new voluntary consensus standard for the measurement of underwater noise from ships is now available from the Acoustical Society of America (ASA) and the American National Standards Institute (ANSI). The new standard will be known as ANSI/ASA S12.64-2009/Part 1, “American National Standard, Quantities and Procedures for Description and Measurement of Underwater Sound from Ships- Part 1: General Requirements”. Noise Control Engineering, Inc. of Billerica, Mass. led the effort to develop the new standard having its Vice President Michael Bahtiarian chair the committee. NCE also provided significant administrative resources to completing the effort. “We started this effort to fill a need for NCE clients designing and building quiet research vessels,” noted Chair Bahtiarian.
