THEimpedancemetry luhlolo oluyingxenye yebhalansi uma kwenzeka ukukhubazeka kokuzwa. Iqukethe ngendlela yokuhlola ukuqina kwe i-membrane tympanique ngakho-ke ikhono layo lokudlulisa ukudlidliza kwemisindo.

Ukuhlolwa kusetshenziselwa ukuhlola isimo somshini wesistimu yokudlulisa umsindo, kodwa futhi ukubekezelela imisindo ephezulu. 

Udokotela angakwazi ukuthola a isithulu, ukuphazamiseka kokuzwa, ukubona ukuba khona kwe-otitis noma ukuphuka noma ukuchithwa kwamathambo.

Ake sikhumbule, ukuze siqonde kangcono, indlela umsindo osakazwa ngayo:

• ngokuqhutshwa komoya: umsindo okhishwayo udala ukundindizela emoyeni okuthathwa yi-pinna kanye nomsele wokuzwa wendlebe (indlebe yangaphandle). Ayadlidliza i indlebe-isigubhu edlulisela umlayezo ochungechungeni lwama-ossicles (isando, i-anvil kanye ne-stirrup, indlebe ephakathi) ku-cochlea (indlebe yangaphakathi). Lokhu kuguqula imisindo ibe yimiyalezo yezinzwa ubuchopho obungayichaza.

• ngokuqhutshwa kwethambo: kulokhu, ukudlidliza okufakwa kugebhezi kusakazwa ethanjeni ngaphandle kokudlula kumshini wokudlulisela indlebe emaphakathi.
