Engineering Solutions to Noise and Vibration Problems

Raymond Fischer

Mr. Fischer founded and led Noise Control Engineering from 1991 until 2017. He currently has the position of Senior Consultant. Ray is a forty-four year veteran working in all areas of acoustics. His experiences include work in the design, development and diagnostics aspects of this field. Mr. Fischer's areas of expertise cover machinery noise control projects in commercial, industrial and marine fields. As a Principle Investigator, he has led NCE’s effort to support the Office of Naval Research (ONR) in its Noise Induced Hearing Loss (NIHL) program.

Mr. Fischer has published many articles on these topics in professional journals. He has also developed innovative approaches to deal with complex acoustic issues. In many cases, Ray has succeeded in balancing noise requirements with non-acoustic constraints on space, weight, maintainability and cost. Over the last twenty-two years, he has developed, maintained and upgraded computer models used to predict resulting noise from various sources and transmission paths. These are based on empirical and semi-empirical techniques that account for airborne, structureborne and fluidborne sources, paths and receiver characteristics. These models have been verified during extensive testing.

Previously Mr. Fischer worked at Bolt, Beranek and Newman (BBN) and Atlantic Applied Research Corporation. At both locations he was a Sr. Engineer in the Marine Acoustic Group, specializing in controlling noise onboard ships. At General Electric, Mr. Fischer specialized in sonar self-noise studies on the SQS-26 sonar system

He has a M.S. in Ocean Engineering from the University of Massachusetts. Mr. Fischer is a co-author of the Society of Naval Architects and Marine Engineers Technical and Research Bulletin 3-37, "Design Guide for Shipboard Airborne Noise Control." He is a member of the Institute of Noise Control Engineers, Institute of Acoustics, ASME, American Acoustical Society, SNAME and the Vibration Institute.
