Acoustics in the 1930s and 1940s<\/h3>\n

Acoustics appeared as an academic field of interest at Texas as early as the 1930s. C. Paul Boner, Physics Department, studied auditoriums and sound studios, organ pipes, and other musical instruments, and Lloyd A. Jeffress, Psychology Department, began a long series of contributions on hearing. Boner and Jeffress were good friends.\u00a0 When the Physics faculty became depleted because of war work during World War II, Jeffress taught freshman physics.\u00a0 Boner, and several other Texas people, were recruited to work in the Harvard Underwater Sound Laboratory (HUSL); Boner served as Associate Director.<\/p>\n

At the end of the war HUSL closed, and about a dozen of its personnel relocated to the University of Texas, including Boner, who resumed his faculty position in Physics, and Robert B. Watson, Claude W. Horton, and (a little later) A. Wilson Nolle, who became new faculty members in Physics.<\/p>\n

In 1945 Boner established the Defense Research Laboratory (DRL) and staffed it with many who had been at HUSL during the war.\u00a0 Although DRL\u2019s early focus was on radar and aeronautics, under the leadership of Richard N. Lane an underwater acoustics program was started.\u00a0 The first contract was on acoustical mine mechanisms.\u00a0 The underwater acoustics program grew rapidly, becoming the dominant part of the Laboratory by the late 1950s.<\/p>\n

Located in some old buildings near the Texas Memorial Museum, DRL was the source of many jobs and research projects for students.\u00a0 It was funded entirely by the federal government, mainly Navy contracts.\u00a0 Although not part of any department, it maintained strong ties to Physics and Engineering.\u00a0 In 1967 DRL moved to Balcones Research Center (now Pickle Research Campus) and in 1968 changed its name to Applied Research Laboratories (ARL:UT).<\/p>\n

Acoustics in Engineering<\/h3>\n

Except for Jeffress, acoustics at Texas before the war and just after was associated with physics.\u00a0 However, development of the underwater acoustics work at DRL began to bring Engineering into the picture.\u00a0 Frank W. McBee and Marcel Gres began working at DRL when they were Mechanical Engineering graduate students and also Instructors.\u00a0 Elmer L. Hixson joined the Laboratory in 1954 at the same time he became Assistant Professor in Electrical Engineering.<\/p>\n

Although Physics faculty members Horton, Nolle, and Watson maintained an ongoing interest in acoustics, the Department\u2019s growth was in other areas and interest in acoustics declined in the 1950s and 1960s.\u00a0 Engineering picked up the slack.\u00a0 About 1960 Hixson set up an acoustics laboratory in EE and began supervising graduate students; he started teaching a transducers course (EE) in 1962.\u00a0 The availability of DRL for support for graduate students prompted ME to look for a faculty person in acoustics.\u00a0 George J. Gruber, Assistant Professor in Mechanical Engineering (1965-71), was recruited in the Mechanical Systems area.\u00a0 Hixson and Gruber soon collaborated to set up and teach two new engineering acoustics courses (ME and EE), one at the graduate level and one at the undergraduate level; these were in addition to the transducers course.\u00a0 A boon to the new program was the large underwater pool, originally intended for use by DRL, in the basement of ENS, the Electrical Engineering building.<\/p>\n

Two new acoustics faculty appeared at the beginning of the 1970s.\u00a0 After a visiting appointment 1969-70 in EE, David T. Blackstock joined ARL:UT and began teaching and supervising acoustics graduate students as Lecturer in ME.\u00a0 Architectural Engineering appointed Douglas D. Reynolds, specialist in noise control and industrial acoustics, Assistant Professor (1971-77).\u00a0 At about the same time ECJ, the new Civil Engineering building, was constructed with an anechoic chamber in its basement.\u00a0 Hixson, Blackstock, and Reynolds set up the current array of seven graduate acoustics courses in Engineering:\u00a0 Acoustics I & II, Transducers, Nonlinear Acoustics, Ultrasonics, Noise Control (now Architectural Acoustics), and Underwater Acoustics.\u00a0 The courses became cross-listed as ME 384N, EE 384N, and ARE 384N (ARE dropped its listing a few years after the departure of Reynolds).\u00a0 This marked the beginning of the current program in acoustics in Engineering.\u00a0 Although the main participating departments have been ME and EE (now ECE), faculty in other departments have also contributed.\u00a0 Physics has also continued to contribute via a small but steady stream of graduate students and the support of faculty members Austin M. Gleeson and Thomas A. Griffy.<\/p>\n

Acoustics in the 1980s and 1990s<\/h3>\n

Acoustics in ME received a big boost in the 1980s with the hiring of Ilene J. Busch-Vishniac (1982) and Mark F. Hamilton (1985).\u00a0 Seminars on acoustical topics had been given occasionally over the years.\u00a0 By 1984, however, acoustical research was so active that the weekly Acoustics Seminar series was started, both to enable faculty and students to report their work and to expose the campus acoustics community to outside speakers, international as well as domestic.\u00a0 The next dozen years were very productive.\u00a0 Hixson, Blackstock (who became full time ME faculty in 1987), Busch-Vishniac, and Hamilton constituted a stable acoustics faculty base, and the sponsored research they generated along with that ARL:UT continued to provide (financial support as well as thesis topics) made it possible for many graduate students to complete master\u2019s and doctoral degrees.\u00a0 Changes came, however, as the end of the 20th century approached.\u00a0 Busch-Vishniac departed (1998) to become Dean of Engineering at Johns Hopkins University, Hixson reached full retirement in 1998, and Blackstock began phased retirement in 1999.\u00a0 The next challenge was therefore to rebuild the acoustics faculty base.\u00a0 In the meantime Hixson and Blackstock continued to teach acoustics courses, despite being in retirement.<\/p>\n

Acoustics in the 21st<\/sup> Century<\/h3>\n

The new century has seen the appearance of new faculty faces in acoustics.\u00a0 In 2002 the new Biomedical Engineering Department hired Stanislav Y. Emelianov as Assistant Professor.\u00a0 Although research interest in medical ultrasound had been developing slowly at Texas since about 1988, Emelianov\u2019s arrival made it a full fledged specialty in the acoustics program.\u00a0 In 2003 ME recruited Preston S. Wilson, widely experienced in experimental acoustics both in air and in water.\u00a0 In 2009 ECE hired Neal A. Hall, who works on acoustic transducers and in particular MEMS (micro-electro-mechanical systems) acoustic sensors.\u00a0 Arrival of the new faculty, with new research interests, assures a continuation of the energy and excellence of the program.<\/p>\n

One measure of the productivity of UT Austin acoustics is in the number of graduates who have taken faculty positions at other universities.\u00a0 Of our graduates between 1985 and 2009, a total of eleven (eight from ME alone) have gone to academia.<\/p>\n

Acoustics at UT Austin enjoys an international as well as national reputation.\u00a0 One indication is the large number of national and international acoustics meetings that have been held in Austin.\u00a0 For example, the Acoustical Society of America began holding national meetings in Austin in 1954 (Richard N. Lane, Chair) and continued at 10-year intervals ever since: 1964 (C. Paul Boner, Chair), 1974 (Chester M. McKinney, Chair), 1984 (David T. Blackstock, Chair), 1994 (F. Michael Pestorius, Chair), and 2003 (Clark S. Penrod, Chair).\u00a0 The Institute of Noise Control Engineering (INCE) held its national meeting, NOISE-CON, in Austin in 1990 (Elmer L. Hixson, Chair).\u00a0 In recognition of Texas\u2019s international renown in nonlinear acoustics, the International Symposium on Nonlinear Acoustics was held in Austin in 1969 (Thomas G. Muir, Chair) and again in 1990 (Mark F. Hamilton and David T. Blackstock, Cochairs).\u00a0 Austin has been the site of many other national and international meetings on specialty topics in acoustics.<\/p>\n

Individual recognition and awards offer another measure of a program\u2019s stature and vigor.\u00a0 As of 2010 awards from the Acoustical Society of America to UT Austin acoustics faculty and\/or graduates include the following:<\/p>\n
