Litaba

• Mefuta e meholo ea audiometry
• 1. Li-audiometry tsa Tonal
• 2. Li-audiometry tsa mantsoe
• Tlhahlobo e etsoa joang
• Mokhoa oa ho itokisetsa tlhatlhobo

Audiometry ke tlhatlhobo ea kutlo e sebeletsang ho lekola bokhoni ba motho ba ho utloa ha ho tolokoa melumo le mantsoe, ho lumella ho fumanoa ha liphetoho tsa bohlokoa tsa litsebe, haholo-holo ho batho ba sebetsang libakeng tse lerata haholo.

Ho na le mefuta e 'meli e meholo ea tlhatlhobo ea audiometry: tonal le lentsoe. Tonal eu lumella ho tseba mefuta ea maqhubu ao motho a ka a utloang, ha lentsoe le shebile haholo ho bokhoni ba ho utloisisa mantsoe a itseng.

Tlhatlhobo ena e tlameha ho etsoa ka lephephe le ikhethang, le kathoko ho lerata, le nka metsotso e ka bang 30, ha le bake bohloko mme hangata le etsoa ke setsebi sa puo.

Mefuta e meholo ea audiometry

Ho na le mefuta e 'meli ea mantlha ea audiometry, e leng:

1. Li-audiometry tsa Tonal

Tonal audiometry ke tlhatlhobo e lekanyang matla a motho a ho utloa, e mo lumellang ho tseba moeli oa hae oa kutlo, tlase le holimo, ka bongata bo fapaneng bo fapaneng lipakeng tsa 125 le 8000 Hz.

Sekhahla sa kutlo ke bonyane ba boemo ba molumo bo hlokahalang e le hore molumo o hloekileng o ka lemohuoa halofo ea linako tseo e hlahisoang ka tsona, bakeng sa maqhubu a mang le a mang.

2. Li-audiometry tsa mantsoe

Audiometry ea lentsoe e lekola bokhoni ba motho ba ho utloisisa mantsoe a itseng, ho khetholla melumo e meng, e hlahisoang ka li-headphone, ka matla a fapaneng a molumo. Ka tsela ena, motho o tlameha ho pheta mantsoe a builoeng ke mohlahlobi.

Tlhahlobo e etsoa joang

Tlhahlobo ea audiometry e etsoa kahare ho lephephe le arohaneng le melumo e meng e ka sitisang tlhahlobo. Motho o roala li-headphone tse khethehileng mme o tlameha ho bonts'a setsebi sa puo, ho phahamisa letsoho, ho etsa mohlala, ha a utloa melumo, e ka hlahisoang ka maqhubu a fapaneng le ka ho fapana tsebeng e 'ngoe le e' ngoe.

Teko ena ha e bake bohloko mme e nka hoo e ka bang halofo ea hora.

Mokhoa oa ho itokisetsa tlhatlhobo

Ha ho boitokisetso bo khethehileng bo hlokehang ho ngola tlhahlobo ena. Leha ho le joalo, maemong a mang, ho ka khothaletsoa hore motho eo a qobe ho pepesetsoa lerata le phahameng le le sa feleng nakong ea lihora tse 14 tse fetileng.
