Tsanangudzo
Ultrasound inoreva chero masaisai eruzha kana kuzunguzika uko kuwanda kwacho kunodarika chikumbaridzo chepamusoro che20kHz (kHz) chinogona kunzwikwa nenzeve yemunhu. Iyo iwizha inonzwika ine frequency yakakwirira kupfuura 20000 Hz. Iyo ine yakanaka kutungamira, yakasimba yekuratidzira kugona, uye zviri nyore kuwana yakawedzera yakadzika acoustic simba. Inoenda kure mumvura kupfuura mhepo, uye inogona kushandiswa kuyera daro, kuyerwa kwekumhanya, kuchenesa, kukweshesa, uye kupwanya. Dombo, sterilization, etc. Ultrasound inoshandiswa zvakanyanya munzvimbo dzakawanda dzakadai semishonga, mauto, indasitiri, zvekurima, njere, nezvimwewo nekuda kwehuwandu hwehuwandu hwemaitiro. Ultrasound inodaidzwa nekuti yakaderera frequency muganho unodarika muganho wepamusoro wekunzwa kwevanhu.
Ultrasonic frequency
Masayendisiti anodana nhamba yekuzunguzika pasekondi kuti frequency yekurira, uye chikamu chayo iHertz (Hz). Ruzha rwemasaisai eruzha rwunonzwa nenzeve dzedu dzevanhu 20Hz-20000Hz. Mafungu eruzha ane frequency yakakwira kupfuura 20,000 Hz anonzi "ultrasonic waves". Iyo frequency yemafungu e ultrasonic anowanzo shandiswa mukuongororwa kwekurapa ndeye 1 MHz kusvika 30 MHz.
Dzimwe mhuka, dzakaita sembwa, ma dolphin, uye zviremwaremwa, dzine nzeve dzinopfuura dzevanhu, nokudaro dzinogona kunzwa masaisai eultrasound. Vamwe vakashandisa chimiro ichi kugadzira nyere dzembwa dzinogona kugadzira masaisai e ultrasonic kudaidza imbwa.
Iyo inonzi ultrasonic waves inongopfuura nepakati uye inertial media, yakadai semhepo. Kana mhepo pachayo ichiwedzera kana kumanikidza, kune wave kupararira kuburikidza nekufamba kwemamorekuru ayo. Naizvozvo, masaisai eruzha haakwanisi kupararira pasina chinhu. Kunzwa kwevanhu kunogona kuona kuchinja uye kudana kuti inzwi. Panguva ino, masaisai eruzha anonzi masaisai anonzwika.
