Abstract: Systems and methods are provided for a visual indication of acoustic energy fields, such as with ultrasonic energy waves. At least one of a plurality of transducers may receive ultrasonic energy waves and convert the received ultrasonic energy waves into a first type of electrical power. A power converter may convert the first type of electrical power into a second type of electrical power. One or more light emitting devices may be powered with the second type of electrical power from the power converter to output light corresponding to the received ultrasonic energy waves by the at least one of the plurality of transducers to provide a visual indication of ultrasonic energy, such as a visual indication of the focus and directionality of the ultrasonic energy waves.
