School Apprentice Program at the Applied Research
Laboratories at The University of Texas provides an early
taste of science and engineering for students entering
their freshman year of college.
The students get experience with research projects designed
by ARL research scientists, who are their mentors for
the summer. The projects deliver real results that the
ARL researchers will use in their work. Read the article

Ideas from Future Researchers
high school graduates "apprentice" with researchers
during the summer, learning what scientists and engineers
do in their chosen area of work. These apprentices
bring fresh approaches and new ideas to their science
and engineering project assignments. Shaun Sherman,
a graduate of Waller High School, studied light
bulbs as a source of generating sound underwater.
High School Apprenticeship Program
The High School Apprenticeship
Program is a competitive program for graduating seniors
of area high schools who plan to attend UT Austin. The
program provides the selected students with exposure
to laboratory research and development, and also provides
the young students with an idea of what scientists and
engineers do in their chosen area of work. Area high
schools are notified of the program, and students who
have an interest in engineering, computer science, physics,
and math are invited to apply. U.S. citizenship is required.
the 146th Meeting of the Acoustical Society of America
Acoustical Society of America (ASA) is primarily a voluntary
organization and attracts the interest, commitment, and
service of a large number of professionals. Their contributions
in the formation, guidance, administration, and development
of the ASA are largely responsible for its worldwide preeminence
in the field of acoustics.
146th Meeting of the Acoustical Society of America was
held in Austin, Texas from 10-14 November 2003 at the
Renaissance Austin Hotel. Applied Research Laboratories
(ARL), The University of Texas at Austin was the host
organization for the meeting. The Meeting General Chair
was ARL’s Executive Director, Dr. Clark Penrod.
Dr. Evan Westwood, a Research Scientist in ARL’s
Environmental Sciences Laboratory, was Technical Program
Chair. Other University research staff and faculty on
the Meeting Local Committee included Dr. Chester McKinney,
a former Director of ARL, ARL Research Professor Dr. David
Blackstock (E. P. Schoch Professor Emeritus in Engineering/UT
Austin Department of Mechanical Engineering), and ARL
Research Professor Dr. Mark Hamilton (Harry L. Kent, Jr.
Professor in Mechanical Engineering/UT Austin Department
of Mechanical Engineering). Many other ARL staff members
also were responsible for the planning, organization and
conduct of the meeting. Especially noteworthy was the
service of Jim Stockton, former head of the Engineering
Services Division at ARL. Jim served as Deputy Chair,
and had a major role in making the meeting a great success
through his thorough attention to detail and his ability
to find solutions to virtually every problem that occurred.
University staff members were recognized during the meeting:
Dr. Chester McKinney was named as an ASA Gold Medal
recipient. The prestigious Gold Medal is presented annually
to an individual whose contributions to the field of
acoustics and to the Acoustical Society have been unusually
distinguished. The medal will be presented to Dr. McKinney
at the 75th Anniversary meeting of ASA to be held in
New York City, NY, in May 2004.
During a plenary session of the meeting, certificates
were presented to the new College of Fellows members
that were elected at the previous meeting held in Nashville,
Tennessee in late May, 2003. Dr. Evan Westwood of ARL
received one of these certificates.
During the College of Fellows Luncheon, University of
Texas Professor Steven Weinberg, Nobel Laureate in Physics
and winner of the National Medal of Science was the
guest speaker. Professor Weinberg, author of The First
Three Minutes, discussed the early universe in the first
few hundred thousand years after the Big Bang. He described
how the entire universe existed as plasma, and that
electromagnetic radiation in the form of light could
not exist at that stage. However, acoustic waves could
and did propagate in the plasma, and he described the
evidence of those early acoustic fields that exists
today in the cosmic background radiation.
Technical tours included a tour of the University Bates
Recital Hall and Visser-Rowland Tracker Organ. Dr. Frank
Speller, Associate Professor of Organ and Harpsichord
was part of a team that provided information and explanations
of the design, construction and installation of the
organ, as well as the design and construction of the
Bates Recital Hall.
The technical sessions included a number of sessions
recognizing the contributions of University researchers:
Acoustical Oceanography and Underwater Acoustics: Aubrey
L. Anderson Memorial Session on Acoustics of Gas-Bearing
Sediments. Aubrey was a Research Engineering/Scientist
Associate V at ARL until January 1977.
Engineering Acoustics, Noise and Architectural Acoustics:
Honoring the contributions of ARL Research Professor
Dr. Elmer Hixson (Professor Emeritus/UT Austin Department
of Electrical and Computer Engineering). One of the
papers presented during this session was “Reflections
on Elmer Hixson’s contributions to architectural
acoustics” by Paul T. Calamaria (Department of
Computer Science, Princeton University).
Acoustics and Biomedical Ultrasound/Bioresponse to Vibration:
Special Session on Nonlinear Acoustics in Honor of Dr.
David Blackstock. Dr. Mark Hamilton co-chaired this
session, and presented a paper, “David Blackstock
and nonlinear acoustics at UT Austin”. ARL Research
Fellow Dr. Wayne M. Wright also presented one of the
invited papers during this session.
a research laboratory of the The University of Texas at
Austin, has a long history in the field of acoustics research.
Many ARL researchers have been and continue to be active
members of the Acoustical Society of America, along with
other researchers and faculty members of the University.
following is from ASA’s
Website and provides some history and a brief description
of the Society:
In 1931 the Acoustical Society joined with three other
scientific societies to form the American Institute of
Physics, an organization designed to unite physics-related
groups and to provide facilities for publishing and other
common activities. The Institute now has 10 member societies
covering a range of physics-related interests.
The Society has attracted members from various fields
related to sound including physics, electrical, mechanical,
and aeronautical engineering, oceanography, biology, physiology,
psychology, architecture, speech, noise and noise control,
and music. This diversity and the opportunity it provides
for interchange of knowledge and points of view has become
one of the strengths of the Society. From its beginning
the Society has tried to serve the interests of workers
in all branches of acoustics, both theoretical and applied.
Two meetings of the Society have been held each year,
except between 1942 and 1945. Papers are presented concerned
with architectural acoustics; psychological and physiological
acoustics; applied acoustics; instruments and apparatus;
music and musical instruments; noise; speech communication;
ultrasonics, radiation, and scattering; mechanical vibrations
and shock; underwater sound; aero acoustics; macrosonics;
acoustical signal processing; bioacoustics; and many more
topics. To assure adequate attention to these separate
fields and to new ones that may develop, the Society establishes
technical committees and technical groups charged with
keeping abreast of developments and needs of the membership
in their specialized fields.
There are now six categories of membership: Honorary Fellow,
Fellow, Full Member, Associate Member, Student Member,
and Emeritus Member.
Since its organization in 1929, the Society has grown
steadily in membership and stature. At this time nearly
7000 men and women who work in acoustics throughout the
U.S. and abroad belong to this prestigious Society. A
variety of fields related to sound are represented:
technologies and instrumentation
and computer sciences
(e.g., concert hall design)
and noise control
acoustics and vibration
This diversity, along with the opportunities provided
for the exchange of knowledge and points of view, has
become one of the Society's unique and strongest assets.
From the beginning, the Acoustical Society has sought
to serve the widespread interests of its members and the
acoustics community in all branches of acoustics, both
theoretical and applied.
