Abstract: This paper deals with an investigation of a method which detects the generation of cloud cavitation by the measurement of cavitation noise. Cavitation noise consists of a pulse train with approximately 1 μs rise time and 10 μs duration and has almost ultrasonic characteristics. By utilizing these chracteristics, the pulses of cavitation noise were measured, and a chart of cumulative pulseheight frequency was obtained. On this chart, the noise pattern due to cloud cavitation on a propeller working in nonuniform flow was clearly distinguished from other cavitation patterns.
