I-LMEC-28 I-Apparatus Yokulinganisa Ukuzwa Nokuzwa

Incazelo emfushane:

Leli thuluzi lifanele abafundi abangaphansi kweziqu zobudokotela kanye nabaphumelele ukuze balinganise ijika le-threshold.Ngokuvamile, incazelo yomkhawulo wobuhlungu kufanele ifinyelele ubuhlungu bezindlebe, kodwa abafundi badinga kuphela ukuqonda isimiso sokuhlola, futhi lapho belinganisa umkhawulo wobuhlungu, badinga kuphela ukulungisa izinga lokucindezela komsindo endlebeni futhi bazizwe bengabekezeleleki.Ngokuhlolwa, abafundi bangaqonda ulwazi oluphathekayo lokuqina komsindo, izinga lokuqina komsindo, ukuphakama, izinga lomsindo omkhulu kanye nejika lokuzwa, futhi babeke isisekelo esihle sokusetshenziswa kwe-audiometry yomtholampilo esikhathini esizayo.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Imisebenzi

1. Ibambise indlela yokulinganisa yokuzwa nokuzwa;

2. Thola ijika lokuzwa lendlebe yomuntu.
