A Hybrid Method Combining Synthesis of a Sound Field and Control of Acoustic Contrast
Spatially confined regions with different sound field characteristics, in the following referred to as sound zones, may be desired in some situations. Recently, various sound field control methods for generating separate sound zones have been proposed in the literature. The different algorithms introduce different levels of control over the physical characteristics of the resulting sound fields. This paper introduces a hybrid of two existing methods employed for obtaining sound zones: 'Energy Difference Maximization' for control of the sound field energy distribution and 'Pressure Matching' which contributes with synthesis of a desired sound field. The hybrid method introduces a tradeoff between acoustic contrast between two sound zones and the degree to which the phase is controlled in the optimized sound fields.
