Izixhobo ze-LMEC-28 zokulinganisa ukuva kunye nomlinganiselo wokuva

Inkcazo emfutshane:

Esi sixhobo sifaneleke kakhulu kubafundi bezonyango abangaphantsi kwe-undergraduate kunye nabafundi abangaphezulu kwe-postgraduate ukulinganisa i-threshold curve. Ngokubanzi, inkcazo ye-threshold threshold kufuneka ifikelele kwintlungu yendlebe, kodwa abafundi kufuneka baqonde kuphela umgaqo wovavanyo, kwaye xa belinganisa i-threshold threshold, kufuneka balungise inqanaba loxinzelelo lwesandi kwindlebe baze bazive benganyamezeleki. Ngovavanyo, abafundi banokuqonda ulwazi oluphathekayo lobunzulu besandi, inqanaba lobunzulu besandi, isandi, inqanaba lobukhulu kunye ne-auditory curve, kwaye babeke isiseko esihle sokusetyenziswa kwe-audiometry yeklinikhi kwixesha elizayo.
