I-audiometry luvavanyo lokuva olunceda ukuvavanya amandla okuva omntu ekutolikeni izandi namagama, ukuvumela ukufunyanwa kotshintsho olubalulekileyo lokuva, ngakumbi kubantu abasebenza kwiindawo ezinengxolo kakhulu.

Zimbini iintlobo eziphambili zovavanyo lwee-audiometry: itoni kunye nelizwi. I-tonal ikuvumela ukuba wazi uluhlu lwamaxesha anokuva umntu, ngelixa ilizwi ligxile ngakumbi kumandla okuqonda amagama athile.

Olu viwo kufuneka lwenziwe kwindlwana ekhethekileyo, eyedwa nengxolo, ihlala malunga nemizuzu engama-30, ayibangeli zintlungu kwaye iqhele ukwenziwa yingcali yokuthetha.

Ezona ntlobo ziphambili ze audiometry

Zimbini iintlobo eziphambili ze audiometry, eziyi:

1. IiToniometry zeToni

I-audiometry yeethoni luvavanyo oluvavanya amandla endlebe omntu, emvumela ukuba abeke umqobo wakhe wokuva, ezantsi nangaphezulu, kumaza aqhelekileyo ahluka phakathi kwe-125 kunye ne-8000 Hz.

Umyinge ophicothwayo lelona nqanaba lisezantsi lokuqina kwesandi esifunekayo ukuze ithoni emsulwa ibonakale isiqingatha samaxesha apho kuboniswa khona, rhoqo rhoqo.

2. Vocal audiometry

I-audiometry yeVocal ivavanya amandla omntu okuqonda amagama athile, ukwahlula izandi ezithile, ezikhutshwa ngee-headphone, ezinamandla ahlukeneyo esandi. Ngale ndlela, umntu makaphinde amagama athethwe ngumvavanyi.

Luqhutywa njani uviwo

Uvavanyo lwe-audiometry lwenziwa ngaphakathi komnquba ohlukaniswe nezinye iingxolo ezinokuthi ziphazamise uviwo. Umntu unxiba ii-headphone ezikhethekileyo kwaye kufuneka abonakalise kwintetho yezonyango, aphakamise isandla, umzekelo, xa esiva izandi, ezinokukhutshwa kumaza ahlukeneyo kwaye ngokuthe ngqo kwindlebe nganye.

Olu vavanyo alubangeli nantlungu kwaye luhlala malunga nesiqingatha seyure.

Ungazilungiselela njani iimviwo

Akukho lungiselelo lukhethekileyo luyafuneka ukuze kwenziwe olu viwo. Nangona kunjalo, kwezinye iimeko, kunokucetyiswa ukuba umntu aphephe ukuvezwa kwingxolo ephezulu nengapheliyo ngexesha leeyure ezili-14 ngaphambili.
