Gwajin gwajin jiyo sauti yana gwada ikon jin sautina. Sauti ya banbanta, gwargwadon ƙarfin su (ƙarfin su) da saurin sautin motsi da sautin (sautin).

Jin yana faruwa yayin da igiyar sauti ke motsa jijiyoyin kunnen ciki. Sautin sannan yana tafiya tare da hanyoyin jijiyoyi zuwa kwakwalwa.

Sautin raƙuman ruwa na iya tafiya zuwa cikin kunnen ciki ta cikin bututun kunne, kunnen kunne, da ƙasusuwa na tsakiyar kunne (isarwar iska) Hakanan zasu iya wucewa ta ƙasusuwan da ke kusa da bayan kunne (gudanarwar kashi).

An auna GASKIYAR sauti a cikin decibels (dB):

  • Waswasi kusan 20 dB ne.
  • Kiɗa mai ƙarfi (wasu kide kide) yana kusan 80 zuwa 120 dB.
  • Injin jet yana da kimanin 140 zuwa 180 dB.

Sauti sama da 85 dB na iya haifar da rashin jin magana bayan afteran awanni. Sauti mai ƙarfi na iya haifar da ciwo nan take, kuma rashin jin magana na iya haɓaka cikin ɗan gajeren lokaci.

Ana auna Sautin sauti a cikin zagaye na dakika (cps) ko Hertz:

  • Onesananan sautunan bass suna kewaye da 50 zuwa 60 Hz.
  • Shrill, sautunan da aka ɗaga sama sunkai 10,000 Hz ko mafi girma.

Matsakaicin yanayin jin ɗan adam kusan 20 zuwa 20,000 Hz. Wasu dabbobin zasu iya jin har zuwa Hz 50,000. Jawabin mutum yawanci 500 zuwa 3,000 Hz.


Mai kula da lafiyar ku na iya gwada jin ku tare da gwaje-gwaje masu sauƙi waɗanda za a iya yi a ofis. Waɗannan na iya haɗawa da kammala tambayoyin da sauraron raɗaɗin muryoyi, kunna cokula masu yatsu, ko sautuna daga yanayin gwajin kunne.

Gwajin fork na musamman da aka gyara zai iya taimakawa wajen tantance nau'in rashin ji.

Babu rashin jin daɗi. Tsawon lokacin ya bambanta. Binciken farko na iya ɗaukar minti 5 zuwa 10. Cikakken tsarin jiyo sauti na iya ɗaukar awa 1.

Wannan gwajin zai iya gano matsalar rashin sauraro a matakin farko. Hakanan za'a iya amfani dashi lokacin da kake samun matsalolin ji daga kowane dalili.

Sakamako na al'ada sun haɗa da:

  • Toarfin jin raɗa, magana ta yau da kullun, da agogo mai ƙwanƙwasa al'ada ce.
