Abstract
An underwater sound generation device may be used for effective control of algae and other microorganisms in ponds and lakes. The sound projector may comprise a thermoacoustic sound transducer and an electronic unit for controlling the operation of the projector. The thermoacoustic projector may include a freestanding carbon nanotube (CNT) film encapsulated between two vibrating plates. The inert gas filled thin acoustical cavity provides a piston-type displacement of the plates and supports a high-temperature operation. A power supply driver, controlling the operation of the sound radiating system, may include a pulse generator, high-power switch amplifier, and a cable, connecting the projector with an electronic driver. The sound control system may provide an omnidirectional sound pressure level in a wide frequency range to affect the algae growth ecosystem over large distances.
