Igor B. Esipov is currently a Professor at Chair of Physics in the Gubkin University of Oil and Gas (Moscow, Russia). He has a part time position as head of the Nonlinear Acoustics Laboratory in the N. N. Andreyev Acoustics Institute. He is one of the sci- entists in Russia that has been con- cerned with the application of para- metric arrays for long-range ocean acoustics. In 1990, under Esipov’s supervision, researchers from the Applied Research Institute, N. Novgorod, performed a pioneering research experiment in parametric sig- nal propagation in the Pacific Ocean using acoustical paths of up to 1000 km. He is a head of the Scientific Council on Acoustics of the Russian Academy of Science, a member of the board government of the Russian Acoustical Society, and a member of the Acoustical Society of America.
The Formula 1 in Room Acoustics now handles array loudspeakers and clusters.

Konstantin Naugolnykh is a Senior Scientist at the National Oceanic and Atmospheric Administration, Earth System Research Laboratory and Zel Technologies, LLC. He received his Ph.D. in physics at the N. N. Andreev Acoustics Institute of the USSR Academy of Sciences in 1959. While at the Institute, he published papers concerning various fields of physical acoustics, including propagation of finite-amplitude acoustic waves and nonlinear acoustic phenome- na. In 1963, he worked with R. Beyer and P. Westervelt in the Department of Physics at Brown University on paramet- ric radiation studies. Dr. Naugolnykh, along with I. Esipov performed experi- ments on the use of the parametric array for long-range ocean sensing. His inter- ests also were in radiation and propaga- tion of an intense acoustic pulse that was generated by an electric discharge or a laser beam. These results were summa- rized in a monograph, Electric Discharges in Water (M., Nauka, 1971), written with N. Roy. He is a member of the Russian Acoustical Society and a fellow of the Acoustical Society of America.
Vladimir I. Timoshenko is a Professor and former head of Electro- Hydroacoustics and Medicine Technology in Taganrog Technology Institute (Taganrog, Russia). In 1965, at Taganrog, he founded a scientific school on Nonlinear Underwater Acoustics. Since then, nine Doctors of Science and about 50 Ph.D’s defended their thesis there. His original engineering research in nonlinear acoustic technology led to the development of a number of para- metric arrays for sub-bottom profiling and shallow water research. Timoshenko created an art gallery and archeology museum at Taganrog where he also manages a series of regular con- certs of musicians and choral groups. Vladimir Timoshenko was a winner of the State Prize on basic research in non- linear acoustics (1985), and is Head of the South Branch of the Russian Acoustical Society. He is also a member of the French Acoustical Society.
