Ngokuthuthuka kobuchwepheshe bolwazi, umphakathi uya ukhathazeka ngomthelela wemisebe kagesi evela ezikhumulweni zokuxhumana ezingenazintambo empilweni yabantu, ngoba omakhalekhukhwini namaphilisi sekuyingxenye ebalulekile yokuphila kwethu kwansuku zonke, kungakhathaliseki ukuthi ukuxhumana nabantu esibathandayo. labo, hlala uthintana nomsebenzi, noma ujabulele nje ukuzijabulisa emgwaqweni, lezi zixhobo ziye zayishintsha ngempela indlela yethu yokuphila. Ngakho-ke kubalulekile ukwenza isiqiniseko sokuthi lawa madivayisi asebenziseka kalula futhi aphephile ukuwasebenzisa. Yilapho kuqala khona ilebhu yokuhlola ye-BTF nobungcweti bayo ekuhloleni i-SAR, RF, T-Coil kanye neVolume control.
Ukuhlola i-SAR (isilinganiso esithile sokumunca) okwenzelwe izinto eziphathwayo, ezifana nomakhalekhukhwini, amathebulethi, amawashi namakhompyutha aphathekayo, njll. Ukuhlola i-SAR incazelo yamandla kazibuthe kagesi amuncwa noma adliwe ngeyunithi ngayinye yesisindo samaseli omuntu. Ilabhorethri yethu yokuhlola ye-BTF igxile kakhulu ekuhloleni i-SAR futhi ihlome ngokugcwele ukuhlangabezana nezimfuneko zendawo yokuhlola, kanye nokuqinisekisa ukuthi okokusebenza kuyahambisana nemikhawulo yokuphepha ebekwe iziphathimandla ezilawulayo. Ngokwenza ukuhlolwa kwe-SAR, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ayibeki ubungozi bezempilo kubasebenzisi.
| Ukuma komzimba | Inani le-SAR (W/Kg) | |
| Abantu Okuvamile/Ukuchayeka okungalawuleki | Ukuchayeka emsebenzini/okulawulwayo | |
| I-SAR Yomzimba Wonke (isilinganiso kuwo wonke umzimba) | 0.08 | 0.4 |
| I-SAR Yomzimba Oyingxenye (isilinganiso ngaphezu kwanoma iyiphi igremu engu-1 yethishu) | 2.0 | 10.0 |
| I-SAR yezandla, izihlakala, izinyawo namaqakala(isilinganiso esingaphezu kwanoma yimaphi amagremu ayi-10 esithishu) | 4.0 | 20.0 |
| QAPHELA:Isibalo Sabantu Okujwayelekile/Ukuchayeka okungalawulwa: Izindawo lapho kunokuchayeka khona kwabantu abangenalo ulwazi noma ukulawula ukuchayeka kwabo. Imikhawulo evamile yabantu/ukuchayeka okungalawuleki iyasebenza ezimeni lapho umphakathi jikelele ungadalulwa noma lapho abantu abavezwe ngenxa yokuqashwa kwabo bengeke baqashwe ngokugcwele ngamathuba okuchayeka noma bangakwazi ukulawula ukuchayeka kwabo. Amalungu omphakathi jikelele angangena ngaphansi kwalesi sigaba uma ukuvezwa kungahlobene nokuqashwa; isibonelo, endabeni yesidluliseli esingenantambo esidalula abantu abaseduze naso.Ukuchayeka emsebenzini/okulawulwayo: Izindawo lapho kunokuchayeka okungase kwenziwe abantu abaqaphelayo amathuba okuchayeka, Ngokuvamile, imikhawulo yokuchayeka emsebenzini/okulawulwayo. zisebenza ezimeni lapho abantu bevezwa khona ngenxa yokuqashwa kwabo, abenziwe baqaphela ngokugcwele amathuba okuchayeka futhi abakwazi ukulawula ukuchayeka kwabo. Lesi sigaba sokuchayeka siyasebenza futhi uma ukuchayeka kungokwemvelo yesikhashana ngenxa yokudlula ngengozi endaweni lapho amazinga okuchayeka engase abe ngaphezu kwenani elivamile labantu/imikhawulo engalawuleki, kodwa umuntu oveziwe uwazi ngokugcwele amandla okuchayeka futhi angakwazi. ukulawula ukuchayeka kwakhe ngokushiya indawo noma ngezinye izindlela ezifanele. | ||
Ishadi lokuhlola le-SAR
I-Hearing Aid Compatibility (HAC) Lesi yisitifiketi sokuthi omakhalekhukhwini bedijithali ngeke baphazamise ukuzwa ingculazi eseduze ngaphambi kokuxhumana, okungukuthi, ukuhlola ukuhambisana kozibuthe kagesi komakhalekhukhwini kanye ne-AIDS yokuzwa, ehlukaniswe izingxenye ezintathu: RF, T- Ikhoyili kanye neVolume control test. Kudingeka sihlole futhi sihlole amanani amathathu, inani lokuqala ukuminyana kukazibuthe kwesiginali yamabomu (isignali yesistimu) kumafrikhwensi amaphakathi ebhendi yefrikhwensi yomsindo, inani lesibili ukuphendula kwemvamisa yesiginali yamabomu kuwo wonke umsindo. ibhendi yefrikhwensi, futhi inani lesithathu umehluko phakathi kwamandla kazibuthe wesignali yamabomu (isignali yesistimu) kanye nesignali engahlosiwe (isignali yokuphazamiseka). Izinga eliyisethenjwa le-HAC yi-ANSI C63.19 (Indlela Kazwelonke Yezinga Yokulinganisa ukuhambisana kwemishini yokuxhumana okungenazintambo kanye nengculaza yokuzwa e-United States), ngokuya ngokuthi umsebenzisi achaza ukuhambisana kohlobo oluthile lwensiza yokuzwa neselula. Ifoni ngokusebenzisa izinga lokulwa nokuphazamiseka lensiza yokuzwa kanye nezinga lokukhishwa kwesignali yeselula ehambisanayo.
Yonke inqubo yokuhlola yenziwa ngokuqala ukulinganisa amandla kazibuthe ebhendini yefrikhwensi yomsindo ewusizo ku-T-coil yokusiza ukuzwa. Isinyathelo sesibili sikala ingxenye yakazibuthe yesiginali engenantambo ukuze kutholwe umthelela wamasiginali wamabomu kubhendi yefrikhwensi yomsindo, njengesibonisi sedivayisi yokuxhumana engenantambo kanye nendlela yamanje yebhethri. Ukuhlolwa kwe-HAC kudinga ukuthi umkhawulo wocingo oluphathwayo oluhloliwe ube ngu-M3 (umphumela wokuhlolwa uhlukaniswe waba yi-M1~M4). Ukwengeza ku-HAC, i-T-coil (ukuhlolwa komsindo) kufanele futhi kudinge umkhawulo ku-T3 (imiphumela yokuhlola ihlukaniswe ngebanga le-T1 kuya ku-T4).
Izigaba zezinga lokuphazanyiswa komsindo we-RFWD RF kumayunithi we-logarithmic

| Isigaba T2 | 10 dB kuya ku-20 dB |
| Isigaba T3 | 20 dB kuya ku-30 dB |

Ishadi lokuhlola le-RF kanye ne-T-coil
Ngokuhlanganisa ubuchwepheshe belebhu yethu yokuhlola ye-BTF nenqubekelaphambili kumakhalekhukhwini kanye nobuchwepheshe bethebhulethi, abakhiqizi bangakhiqiza amadivayisi anganikezi nje kuphela ulwazi olungenazihibe lomsebenzisi kodwa futhi ahlangabezane nazo zonke izindinganiso zokuphepha. Ukusebenzisana phakathi kwelebhu yokuhlola ye-BTF nomkhiqizi kuqinisekisa ukuthi idivayisi ihlolelwa i-SAR, i-RF, i-T-Coil nokuthobelana nokulawulwa kwevolumu.
