Detection and calibration of focus sound field characteristics in EWSL
摘要
Abstract
To test the sound field characteristics of the focal position of EWSL and to determine whether the standard is in compliance with relevant national standards, the needle hydrophone was used to scan the layers in the time and space domain so as to find the position of the focus and to measure the sound pressure intensity at the focal position.The energy distribution of the focal position was displayed by the energy chart.Through the measurement, the sound field intensity, the rise time and the pulse width of the 10 shock waves were collected.The results show the EWSL focus sound field characteristics meet the national standards.关键词
