I-Stethoscope yeMakrofoni yodonga yokumamela ngokufihlakeleyo kwiindonga
Ukusetyenziswa kweMveliso
Inkcazo
Ezi transducer zimbini zinamandla ziphulaphula ngesixhobo sodonga sesona sihlaziyiweyo kwiimveliso ezifanayo kule mihla, nto leyo enokunika umphulaphuli ulwazi olucacileyo lwesandi abaya kulwazi. Esi sisandisi-lizwi esikhethekileyo esiya kuthatha ingxolo encinci kwizinto eziqinileyo ezifana nodonga, ukuze ukwazi ukumamela okwenzekayo kwelinye icala. Imakrofoni yoqhagamshelwano yipini yeseramikhi eyenzelwe ngokukodwa ukuguqula ukungcangcazela kube yingxolo evakalayo. Ine transducers ezimbini ezinamandla kunye eziquka isixhobo sokujonga esikhethekileyo ukuvumela amapolisa, amabanjwa njalo njalo.
