Hydroacoustic Power Conversion [PDF]
The Journal of the Acoustical Society of America, 1970 Hydroacoustic power conversion is the controlled generation of acoustic or vibratory energy from hydraulic power. Basic concepts of high-power self-excited hydroacoustic vibration generators are described, the envelope of interest covering frequencies ranging from the subsonic region to the kilohertz region, and power levels extending in some instances
