The leadoff for the technical program ...
The leadoff for the technical program is scheduled to be given on Wednesday morning at the plenary session by Dr. Ira Dyer, professor of ocean engineering at M.I.T.
The1996 Gold Medalist is Professor Ira Dyer of the Massachusetts Institute of Technology (MIT).
The award of the Gold Medal to Ira
recognizes a distinguished career in acoustics spanning close to five decades.
has had a major influence on all aspects of the Acoustical Society of America
His research has had a profound impact upon aeroacoustics, structural acoustics, and underwater acoustics; he has been a mentor for many students who are now prominent acousticians in their own right, and a leader in education for acoustics; finally, he has served the Society as President, Vice-President, and Executive Council member.
He has served on numerous committees, blue ribbon panels, and advisory boards for both the Society and many government agencies.
Ira was born in Brooklyn, New York on 15 June 1925.
After serving in the Army Air Corps he went to MIT and obtained his S.B. (1949), S.M. (1951), and Ph.D. (1954) all in physics.
They have two children, Sam and Deborah, and three grandchildren who Ira
is now training to be accomplished sailors on his
After his graduate studies Ira joined Bolt Beranek and Newman Inc. (BB&N) where he led a division which contributed to virtually all aspects of sound and vibration in complex structures involving ships, submarines, aircraft, and spacecraft, resulting in many publications in The Journal of the Acoustical Society of America (JASA).
In 1971 Ira
accepted the positions of Head of the Department of Naval Architecture and Marine Engineering and the Director of Sea Grant.
He soon led the Department into new areas in ocean engineering which emphasized learning about the ocean environment.
The character of the Department was changed profoundly and its new name and status as Department of Ocean Engineering is now known worldwide.
Those of us who have been fortunate enough to have Ira as an instructor know that he is a consummate lecturer with a clarify that makes it all but impossible not to learn in his class.
has also conducted an active research program while at MIT
Initially, it concerned the statistics of ambient noise especially as related to distant shipping, leading to fundamental new insight on the nature of acoustic fluctuations in the ocean.
In 1975 Ira
launched a program, which continues even now, on Arctic acoustics.
CANBARX, the first experiment, concerned transoceanic reverberation in the Canada Basin.
In nine major field experiments since, we have studied reverberation, propagation, and ambient noise in the Arctic, leading to hundreds of publications.
In the course of this research work Ira became the expert on ambient noise mechanics.
Whereas others gathered and summarized data, he
explored the fundamental mechanisms of the noise generation and its coupling to the ocean.
In the last few years he
has led MIT's efforts in structural acoustics.
was the organizer of a workshop at the Woods Hole which set the agenda for the Office of Naval Research's (ONR) program.
students are now making seminal contributions on the backscattering and radiating by complex objects as well as new methods for their control.
has received many awards and honors in his
long and distinguished career.
He is a Fellow of both the Acoustical Society of America and the Institute of Electrical and Electronic Engineers and a member of the National Academy of Engineering.
It is richly deserved that he
add to his
honors the Gold Medal of our Society.

We present, for a non-specialist audience, a glimpse of problems and actualities connected with use of sonars for target detection in shallow water.We use data from shallow water oceanographic and acoustics experiments conducted in 1997 in the East China Sea, and in 1998 and 1999 in the Sea of Japan, off the coast of Korea.From these data we: (1) assess the environmental complexities as they impact acoustic propagation, and thereby cause variability in its transmission loss (TL), and (2) assess the impact of TL variability on the sonar detection problem.From the data, and from other information sources, oceanography of these shallow waters entails water mass fronts, currents, and internal tides, which cause fluctuations in the background sound-speed stratification.Some of these oceanographic complexities turn out to be important in sonar detection, some not so.Data on bottom geology were not acquired in these tests.
...Ira Dyer received the SB, SM and PhD degrees in 1949,1951 and 1954 from MIT.
served in the USAF from 1944-45.He served as Vice President of Bolt Beranek and Newman, Inc from 1951-1970.In 1970 he became Professor of Ocean Engineering at MIT and has continued in that capacity.He became Emeritus in 1996 and continues working as an Independent Consultant.He was Director of the MIT Sea Grant College Program from 1973-75.He
has been elected to the National Academy of Engineering
, awarded the Gold Medal and the Lindsay Medal of the Acoustical Society of America
(ASA), awarded the Per Bruel Gold Medal for Noise Control and Acoustics by ASME International, received the Distinguished Technical Contribution Award from the IEEE Council on Oceanic Engineering
, and obtained the Meritorious Public Service Award from the U.S. Coast Guard
.He is a Fellow of the ASA, of the IEEE, and of the AAAS, and is past President of the ASA.His
principal areas of interest have been in the experimental use of sound waves to explore the ocean, measurements and theory of ambient noise in the ocean, and design and evaluation of sonar systems to detect and localize objects in the ocean.He
has published over 135 papers and book chapters on ocean acoustics, sonar systems, hydro-acoustics, aero-acoustics, and structural acoustics.The meeting will be held at the Lincoln Lab Auditorium at 4:00 PM.Refreshments will be served at 3:30 PM.Registration is in the main lobby.
