Uma ubonile isitshalo se- cochlear , ungase uzibuze ukuthi idivayisi enjalo yaba kanjani. Umlando kanye nokuthuthukiswa kwesitshalo se-cochlear, ithuluzi lwanamuhla lokuzwa , empeleni lisho amakhulu eminyaka.
Ama-pre-Modern Times
Cishe ngo-1790, umcwaningi okuthiwa uVolta wabeka izinduku zensimbi ezindlebeni zakhe futhi wawaxhuma esifundeni. Lona ngumzamo wokuqala owaziwayo wokusebenzisa ugesi ukuzwa.
Kamuva ngo-1855, kwaqalwa umzamo wokugqugquzela indlebe ngekhompyutha. Kwakukhona nezinye izivivinyo zokusebenzisa ukwelashwa kagesi ngezinkinga zezindlebe.
Isiliva Sesiliva
Esikhathini sokucindezeleka kweminyaka ye-thirties, abacwaningi bathola ukuthi ukubeka i-current eduze kwendlebe kungadala ukuzwa okucatshangelwayo. Umphakathi wesayensi uye wafunda kabanzi mayelana nokuthi i-cochlea isebenza kanjani. Kwabaluleka okubalulekile lapho abacwaningi bethola ukuthi amandla kagesi angaguqulwa abe umsindo ngaphambi kokufinyelela indlebe yangaphakathi.
Unyaka ka-1957 walethe ukuvuselela kokuqala kwe-acoustic ne-electrode, ngabososayensi uDjourno no-Eyries. Kulolu cwaningo, umuntu onesifo sakhe esashukumiselekayo angazwa umsindo wangemuva.
Ucwaningo lwanyuka ngokushesha eminyakeni engamashumi ayisithupha. Kube nokucwaninga okuqhubekayo ekugqugquzelweni kagesi kwe-acoustic nererve. Kwasungulwa okukhulu lapho abacwaningi bezwa ukuthi izinzwa ezithile zokucwaninga kufanele zivuselelwe ngama-electrode ku-cochlea ukuze zikhiqize umsindo.
UDkt. William House wakha iziguli ezintathu ngo-1961. Bonke abathathu bathola ukuthi bangazuza kulokhu okufakiwe. Eminyakeni embalwa kamuva, ngo-1964 kuya ku-1966, kwafakwa ama-electrode amaningi e-cochleas, ngemiphumela eyanelisayo. Abacwaningi bafunda kabanzi mayelana nokubeka ama-electrode kanye nemiphumela yalokho kubeka.
Times Yanamuhla
Ubuchwepheshe bokusetha buqhubekele phambili eminyakeni engamashumi ayisikhombisa kuya kwezi-90. Ama-seventies abona abantu abaningi bethola ukufakwa, ukucwaninga okuqhubekayo, nokuthuthukiswa kwedivayisi eminingi.
Ngo-December 1984, ukufakelwa kwe-cochlear kwakungazange kubhekwe ukuhlolwa futhi kunikezwe isitembu sokugunyazwa kwe-FDA sokufakwa kubantu abadala.
Kuwo wonke ama-nineties, ezinye izinto zithuthukisiwe ekusetshenzisweni kwenkulumo nakwezinye izinto zobuchwepheshe bokufakelwa, ikakhulukazi ukusungulwa kwenqubo yokukhulumisana ukuze kuhlanganiswe kudivayisi efana nosizo lwe-BTE.
