Tanthauzo
Ultrasound imatanthawuza mafunde aliwonse a phokoso kapena kugwedezeka komwe ma frequency amaposa 20kHz (kHz) yomwe imamveka ndi khutu la munthu. Ndi mafunde amawu okhala ndi ma frequency apamwamba kuposa 20000 Hz. Ili ndi chiwongolero chabwino, luso lowonetsera mwamphamvu, ndipo ndiyosavuta kupeza mphamvu zambiri zamayimbidwe. Imayenda kutali kwambiri m’madzi kuposa mpweya, ndipo ingagwiritsidwe ntchito poyezera mtunda, kuyeza liwiro, kuyeretsa, kuwotcherera, ndi kuswa. Mwala, kutsekereza, etc. Ultrasound imagwiritsidwa ntchito kwambiri m'madera ambiri monga mankhwala, asilikali, mafakitale, ulimi, nzeru, etc. chifukwa cha makhalidwe ake apamwamba. Ultrasound imatchedwa chifukwa chakuti malire ake otsika amaposa malire apamwamba akumva kwa anthu.
Akupanga pafupipafupi
Asayansi amatcha kuchuluka kwa kugwedezeka pa sekondi iliyonse kuchuluka kwa mawu, ndipo gawo lake ndi Hertz (Hz). Kuchuluka kwa mafunde amawu omwe makutu athu amunthu amatha kumva ndi 20Hz-20000Hz. Mafunde amawu okhala ndi ma frequency apamwamba kuposa 20,000 Hz amatchedwa "mafunde akupanga". Mafupipafupi a mafunde akupanga omwe amagwiritsidwa ntchito kwambiri pozindikira zachipatala ndi 1 MHz mpaka 30 MHz.
Nyama zina, monga agalu, ma dolphin, ndi mileme, zili ndi makutu kuposa anthu, choncho zimatha kumva mafunde a ultrasound. Ena agwiritsa ntchito izi kupanga zitoliro za agalu zomwe zimatha kupanga mafunde akupanga kuti aziyitanira agalu.
Zomwe zimatchedwa mafunde akupanga zimangodutsa zotanuka komanso zosagwira ntchito, monga mpweya. Mpweya wokhawo ukakula kapena kuponderezedwa, pamakhala kufalikira kwa mafunde kudzera mukuyenda kwa mamolekyu ake. Choncho, mafunde a phokoso sangathe kufalikira m'malo opanda kanthu. Kumva kwa anthu kumatha kuzindikira kusinthasintha ndikukutcha kuti kumveka. Panthawi imeneyi, mafunde a phokoso amatchedwa mafunde omveka.
