Dr. Ilene Busch-Vishniac (President, Acoustical Society
of America)
Hospital Noise Characterization and Control / State of
the ASA
Abstract: Although there have been a few focused studies
of noise in particular areas of a hospital, and some work has been done to
correlate noise to effects on people in hospital settings, there has never been
a comprehensive study of the noise in a hospital setting. We are about to embark on a study of
hospital noise focusing first on characterization of the main noise sources,
and comparisons of older and newer buildings in terms of noise. We will progress in phase 2 of our
study to methods of noise mitigation.
In this talk, we summarize work reported in the literature, and what we
have found to date. We will also
delineate the particular challenges of working in a hospital environment
compared to private homes or other businesses. The second part of this talk will
be dedicated to a few words on the state of the Acoustical Society of America
and to share my vision for the society.
Biography: Ilene Busch-Vishniac is a Professor of
Mechanical Engineering at Johns Hopkins University in Baltimore, MD where from
1998-2003 she served as the sixth dean of the Whiting School of
Engineering. Dr. Busch-Vishniac
received her undergraduate degrees in Physics and Mathematics from The
University of Rochester, and MS and PhD degrees in Mechanical Engineering from
MIT. She worked at Bell
Laboratories in the Acoustics Research Department before joining the Mechanical
Engineering faculty of The University of Texas in 1981. She remained at The University of Texas
until 1998, when she joined Johns Hopkins University as Professor and
Dean. Dr. Busch-Vishniac has
received many teaching and research awards, including the Achievement Award of
the Society of Women Engineers, the Curtis McGraw Research Award of the
American Society for Engineering Education, and the Silver Medal in Engineering
Acoustics of the Acoustical Society of America. She has served in various professional organizations
including a term as President of the Acoustical Society of America, and a term
on the Engineering Deans Council of the American Society of Engineering
Education. She has authored
roughly 60 technical articles and one book, and holds 9 US patents on
electromechanical sensors. Dr. Busch-Vishniac is married and has two teenage
daughters. Two unruly dogs
complete the family.

Dr. Kevin LePage
Computational Aspects of Reverberation Predictions for
Littoral Environments
Abstract: The prediction of mean reverberation level and
reverberation envelope statistics for littoral environments is of importance
for the prediction of active system performance. Here some recent advances in the computation of both
coherent and incoherent properties of reverberation in shallow water are
described.
Biography: Kevin LePage is a Research Physicist in the
Acoustic Systems branch at the Naval Research Laboratory. His current interests include the
calculation of propagation, scattering and reverberation in the presence of
environmental uncertainty and coherent effects in shallow water acoustics. Prior to joining NRL he was a Scientist
at Bolt, Beranek and Newman in Cambridge, MA, where he worked in the areas of
structural acoustics, arctic acoustics and active noise and vibration control,
and a Senior Scientist at SACLANT Undersea Research Centre, where he developed
the BiStaR and R-SNAP reverberation models, a sediment volume scattering module
for OASES, and a bistatic synthetic aperture algorithm for use on AUVs in the
presence of navigational uncertainty.
Dr. LePage received a BS in Marine Engineering from Webb Institute in
1983 and a MS and Ph.D. in Ocean Engineering from MIT in 1987 and 1992,
respectively.
