Imishini ye-LMEC-28 Yokulinganisa Ukuzwa Nomkhawulo Wokuzwa

Incazelo emfushane:

Leli thuluzi lifanelekela abafundi bezokwelapha abangaphansi kweziqu kanye nabafundi abaphothule ukukala ijika lomkhawulo. Ngokuvamile, incazelo yomkhawulo wobuhlungu kufanele ifinyelele ebuhlungwini bendlebe, kodwa abafundi badinga ukuqonda isimiso sokuhlolwa, futhi lapho belinganisa umkhawulo wobuhlungu, badinga kuphela ukulungisa izinga lokucindezela komsindo endlebeni futhi bazizwe bengabekezeleleki. Ngokuhlola, abafundi bangaqonda ulwazi olungokoqobo lokuqina komsindo, izinga lokuqina komsindo, umsindo, izinga lomsindo kanye nejika lokuzwa, futhi babeke isisekelo esihle sokusetshenziswa kwe-audiometry yezokwelapha esikhathini esizayo.

Imisebenzi

1. Yazi indlela yokulinganisa yokuzwa kanye nomkhawulo wokuzwa;

2. Nquma ijika lomkhawulo wokuzwa wendlebe yomuntu.
