Iyo unit of sound pressure is Pa (Pa), uye saizi yayo inoratidza simba reizwi wave, ndiko kuti, simba reiyo wave simba rekuparadzira. Iyo yakakura kudzvinyirira kwenzwi, iyo yakakura kusimba kweiyo ultrasound uye kusimba kwesimba rinopfuudzwa. Parizvino ndeimwe yehuwandu hwakakosha hwemuviri hunowanzo shandiswa kutsanangura maitiro emafungu eruzha. Kuburikidza nekuyerwa kwekumanikidza kwenzwi, humwe huwandu hwemuviri hwakadai senge particle velocity hunogona kuwanikwa zvisina kunanga.
Munguva yekupararira kwemafungu enguva refu mune elastic medium, kudzvanywa kwemadotsi epakati kunoshanduka nekufamba kwenguva, uye kuwanda kwemadotsi epakati kwakakora uye kushoma. Zvinoenderana nemusimboti wekubatanidza, isu tinogona kufunga nezve inoenderera svikiro seyakaumbwa nezvakawanda zvakabatana zvakabatana zvidiki vhoriyamu zvinhu dV. Iyo yepakati mune yakadai vhoriyamu element dV inogona kutariswazve senge hombe ine huremu hwe ρdV. ρ ndiyo density yepakati, inova chiyero chinoshanduka nenguva uye chinzvimbo pasi pekuita kwemafungu eruzha. Mushure mekunge vhoriyamu element dV yakanganiswa nemasaisai eruzha, kudzvanywa kunoshanduka kubva p0 kusvika p1, ipapo iyo yakawandisa kumanikidza p kunokonzerwa nekukanganiswa kwemafungu ezwi kunonzi kumanikidza kwenzwi: p = p1- p0
Nekuda kwehupfupi wavelength uye yakakwira frequency yemafungu e ultrasonic, simba rainaro rakakura kwazvo, izvo zvinogona kukonzera yakakosha kudzvanywa kwenzwi pazvikamu zvepakati.
Kushandisa: Ultrasonic application muchikafu: ultrasonic blade, ultrasonic cutting machine
