ATI's Computational Acoustics course
Vibro-acoustics modeling using the latest
in Computer Aided Acoustics Design
Dr. Hamid Bouhioui, Instructor
At the beginning of the 20th century acoustics
seemed still to be nothing but a field of scientific
curiosity. Since then, noise control has become a
necessity, which has led to a diversification of the
approaches, methods and techniques used to
understand and resolve various categories of
problems. Computers provide a unique tool for the
analysis and design of these problems and they
have become instrumental in achieving optimal
solutions to complex acoustical problems.
Dr. Hamid Bouhioui is the founder of BC
Acoustics, a consulting company based in Vancouver
British Columbia, Canada. He is specialized in
Acoustics, Vibrations and Noise control. He managed
various projects including for companies such as
Boeing-USA, and High Speed Train-France. He has
been Invited lecturer at: The Boeing Company,
Seattle; The Audio Engineering Society, Vancouver
BC; The Acoustical Society of America, Seattle; The
Computer Science Department, UBC; Canadair –
Bombardier, Montreal; Saint-Gobain Vitrage
Company, Paris; The Composites Group at UBC; The
Civil Engineering Department at UBC and Several
International Acoustics meetings.
