Sound installation and performance
Sound is generally assumed to diffuse and fill an environment and be omnidirectional. Light is assumed to travel in a straight line and be more amenable to being directed such as in a laser or even a torch or a spotlight. We may not be able to see around a corner but we can hear around a corner. Ultrasound provides one means by which sound can be more directional and behave more similarly to how we imagine light to be, allowing us almost to “see” via sound.
