Instruments used to study the structure and alteration of sound fields are designed, and their performance is determined.
Emphasis is placed on the applicaton of computer-based electronics in solving acoustical problems.
These studies have produced a specialized sound system for use in the White House, a new motion picture theater sound system for employment with a high-technology screen, and numerous successful commercial loudspeaker system designs. Another subject area of interest which is supportive of the above work is that of signal processing. Both theoretical and experimental work is carried out in this area. The theoretical studies involve data compression, spectral shaping, and encode-decode techniques. The experimental work is performed by making digital recordings of analog signals which are subsequently fast Fourier transformed in a digital computer operating in real time.
