Annapolis Laboratory contribution to structureborne noise measurement and analysis

Abstract

The Annapolis Laboratory of the Carderock Division of the Naval Surface Weapons Center has continually been in the forefront of the development of instrumentation and standards for the measurement and analysis of the structureborne noise generated by shipboard machinery. This effort included but was not limited to sensor mounting and calibration techniques, equipment mounting fixtures, analysis instrumentation, and criteria for permissible shipboard machinery noise levels. The Laboratory also established the Machinery Acoustic Data Information Center (MADIC), which provided the Navy’s only central source of such information for ship design and operational requirements. One of the results of this effort was MIL-STD-740, the military standard for machinery noise measurement procedures and criteria. An ASA/ANSI standard S2.16-1997, which was based upon MIL-STD-740, has recently been issued.
