I-LMEC-28 isiXhobo soMlinganiso weNtetho yokuVimba kunye noMfanekiso oManyeziweyo

I-LMEC-28 isiXhobo soMlinganiso weNtetho yokuMamela kunye nokuMamela

Inkcazelo emfutshane:

Esi sixhobo sifanelekile kubafundi bezonyango kunye nabafundi be-postgraduates ukulinganisa i-threshold curve.Ngokuqhelekileyo, inkcazo yentlungu yentlungu kufuneka ifikelele kwiintlungu zendlebe, kodwa abafundi kufuneka baqonde kuphela umgaqo wovavanyo, kwaye xa belinganisa intlungu yentlungu, kufuneka kuphela ukulungelelanisa inqanaba loxinzelelo lwesandi kwindlebe kwaye bazive benganyamezeleki.Ngovavanyo, abafundi banokuqonda ulwazi lomzimba lokuqina kwesandi, inqanaba lokuqina kwesandi, isandi, inqanaba lesandi kunye negophe lokuva, kwaye babeke isiseko esihle sokusetyenziswa kwe-audiometry yeklinikhi kwixesha elizayo.
