Mr. Fischer received his M.S. in Ocean Engineering from the University of Massachusetts, Amherst in 1976. He was employed by Bolt, Beranek, and Newman (BBN) for 12 years and by Atlantic Applied Research for 5 years. In 1990 he started his own company, Noise Control Engineering, Inc. He retired in 2016.Mr. Fischer was extensively involved with the prediction of radiated noise, sonar self-noise, habitability noise, aural detectability, and structural vibrations on over 400 different vessels. He has also directed many shipboard noise and vibration measurements for demonstration of compliance with habitability criteria, for diagnostic testing, and to verify noise modeling techniques. His area of specialty includes design, development, and noise control engineering to solve noise and vibration problems in small high-speed craft, yachts, work boats, ice breakers, naval surface ships, and other non-conventional vessels. He was the Technical Leader for a US Navy Small Business Innovative Research (SBIR) program to provide more accurate shipboard airborne noise predictions. He co-authored the original and a Supplement to SNAME's Design Guide for Shipboard Airborne Noise Control, T&R 3-37. He has also contributed to the development acoustic goals and several design guides for the US Navy and the Canadian Navy.



Mr. Fischer was the Principle Investigator for the Office of Naval Research's (ONR) Noise Induced Hearing Loss (NIHL) program. This multi-year effort, started in 2010, provided new acoustical engineering tools and defined new management and programmatic approaches for Navy acquisitions. New acoustic modeling tools were established for composite material constructions, underwater radiated noise, and for small Marine Corps vehicles.

Mr. Fischer was the project manager for the habitability and radiated noise control effort on NOAA's Fisheries Research Vessel (under contract with VT Halter Marine), Fast Missile Craft (FMC), and the Alaska
