Jose C. Ortega received a B.S. degree in physics from the University of California, Los Angeles (UCLA) in 1957. Graduate work in physics with emphasis in acoustics led to an M.S. degree in 1961 from UCLA. He began his professional career in 1956 at Veneklasen Associates and its affiliate Western Electro-Acoustic Laboratory and that association continues today. His professional work has included microphone design and calibration, jet engine noise suppression, environmental noise studies, development of instrumentation and measurement methods related to acoustical scale models, managing an acoustical laboratory for testing of commercial products, and the design and evaluation of auditoria, television and recording studios. Mr. Ortega is currently Principal Emeritus at Veneklasen Associates, Inc. and an acoustical measurement consultant at Western Electro-Acoustic Laboratory, Inc.

Mr. Ortega's interests outside of his professional area include his family, reading Christian and classical books, woodworking, music, preservation of the natural environment and activities at his local church.

John J. LoVerde received his Bachelor of Science degree in Mechanical Engineering from California State Polytechnic University, Pomona in 1989. He earned a Masters Degree in Acoustics for the University of California, Los Angeles. At UCLA he worked on the link between the acoustical energy and listener reaction to sound within auditoria. John has published over 20 technical papers in acoustics, teaches and lectures internationally presenting at the last seven meetings of the Acoustical Society of America (ASA).

David Lubman is an acoustical consultant/scientist in Orange County, California specializing in architectural acoustics and noise.

He is interested in the acoustics of performance spaces for music and voice. In addition to being the past Senior Editor of

Myron Mann is a professional educator, having a long career as a professor of physics in the Los Angeles Community College District. In addition to his continued service in that capacity on a part-time basis in semi-retirement, he teaches one physics class in a private high school. While pursuing graduate studies in physics, he worked part-time in acoustics, initially in the aerospace industry and later with an acoustical consulting firm. The latter employment continued throughout his teaching career during summer breaks.

While engaged in college teaching, Mr. Mann developed and taught a very popular course in introductory acoustics. Many of his students were either professional musicians or were preparing for employment in the commercial music industry. Having had a lifetime of experience in vocal performance ranging from solo work to church choir to oratorio chorus, Mr. Mann is himself an active amateur musician.
