Abstract
Systems and methods for generating a controlled sound field. In one example, the system and method perform or include receiving a sound wave emitted from a sound source; determining, with an electronic processor, a pattern of at least one of an amplitude change and a phase change necessary to create a desired sound field using the sound wave; determining, with the electronic processor, a plurality of passive sound-modulating elements needed to generate the pattern of at least one of the amplitude change and the phase change; and constructing the plurality of sound-modulating elements to generate the controlled sound field.
