Mr. Fischer is a twenty-six
year veteran and has worked in all areas of acoustics.
He has a M.S in Ocean Engineering from the University
of Massachusetts. His experience includes work
in the design, development, and diagnostics aspects
of this field. Mr. Fischer's areas of expertise
covers machinery noise control projects in commercial,
industrial, and marine fields.
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 most cases,
he has succeeded in balancing noise requirements
with non-acoustic constraints on space, weight,
maintainability, and cost. Over the last twenty
years, he has developed, maintained and upgraded
computer models used to predict resulting noise
for various sources and transmission paths.

Responsibilities and Projects
Mr. Fischer is extensively involved
with the prediction of radiated noise, sonar self
noise, habitability noise, aural detectability and
structural vibrations on a large variety of vessels.
He has also directed many shipboard noise and vibration
measurements for demonstration of compliance with
habitability criteria, for diagnostics 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, submarines and other non-conventional vessels.
Mr. Fischer is involved in the
design, installation and testing of numerous isolation
systems, including single and double stage stanchion
isolation systems. He is also directing machinery
condition monitoring systems for several marine operators.
Other types of projects include industrial and construction
site noise control, environment noise evaluation abatement,
and design of acoustic test facilities.
Mr. Fischer has co-authored a technical
document for SNAME entitled “Design Guide for Shipboard
Airborne Noise Control, “TR-3 37”, January 1983 and
is currently up-dating this document at the request
of the US Navy. He has also contributed to the development
of several design guides for the US Navy and Canadian
Navy. Based on these documents, Mr. Fischer and two
other lecturers offer a short course at State College,
PA. He develops, maintains, and updates computer models,
SNAP-Ship Noise Analysis Program, prediction techniques,
accounts for both airborne and structureborne source,
path, and receiver characteristics.
Mr. Fischer has implemented four-pole
lumped and distributed parameter vibration prediction
models. He has contributed to the implementation of
SEA models that apply to habitability noise and underwater
radiated noise predictions for marine vehicles, including
the USNS HAYES. Finite Element Analysis methods have
applied to hull, mast and house vibration predictions.
Noise control treatments have been
successfully designed and installed on advised light
weight craft such as Surface Effect Ships (SESs),
helicopters (Bell Ranger), hydrofoils (PHM), and small
water craft. Diagnostic tests have been conducted
on private aircraft in support of an on-going ADE
Development Corp. program to reduce noise on these
