In this thesis the fundamental problem in signal processing of controlling a sound field
within a region of space is studied. Using spherical and cylindrical harmonics, reproduc-
tion systems in both two and three dimensions have been designed. From the design of
the systems, equations are derived describing the performance of the system for arbitrary
