ABSTRACT
Ultrasound technology has been used in many fields for measurement, imaging, and even therapeutic goals. Recently ultrasound has become available as a medium to create hyper-directional sound beams, enabling the ability to manipulate sound projection in a way analogous to light. This paper presents a brief overview of ultrasound audio technology, and introduces several lines of investigation related to applications of sound beams in performance and sound art currently under development at our center.
