METHOD FOR MEASURING NOISE OF CAVINATION THROUGH ELECTROMAGNETIC WAVE DETECTION

摘要

PURPOSE: A method for measuring noise of cavination through electromagnetic wave detection is provided to measure only noise generated and transformed by a pressure change of cavination generated by the movement of a mechanical object in the water. CONSTITUTION: A method for measuring noise of cavination through electromagnetic wave detection includes the steps of receiving electromagnetic wave, which is emitted by the deformation of cavination(110) generated from a mechanical object moving in the water, into an electromagnetic wave receiver(120), grasping intensity of the wave, comparing the wave with data, and measuring a level of noise of cavination. The cavination has an electromagnetic field property.
