Hearing Aid Compatibility (HAC) imatanthawuza kugwirizana pakati pa foni yam'manja ndi chothandizira kumva ikagwiritsidwa ntchito nthawi imodzi. Kwa anthu ambiri omwe ali ndi vuto lakumva, zothandizira kumva ndi zida zofunika kwambiri pamoyo wawo watsiku ndi tsiku. Komabe, akamagwiritsa ntchito mafoni awo, nthawi zambiri amasokonezedwa ndi ma electromagnetic, zomwe zimapangitsa kuti anthu asamve bwino kapena phokoso. Pofuna kuthana ndi vutoli, bungwe la American National Standards Institute (ANSI) lapanga miyezo yoyenera yoyesera ndi zofunikira zotsatiridwa kuti zigwirizane ndi HAC pazithandizo zamakutu.
Ku United States, anthu oposa 37.5 miliyoni ali ndi vuto la kumva. Pakati pawo, pafupifupi 25% ya anthu azaka zapakati pa 65 ndi 74 ali ndi vuto lakumva, ndipo pafupifupi 50% ya okalamba azaka 75 ndi kupitilira apo amavutika ndi vuto lakumva. Pofuna kuwonetsetsa kuti anthuwa ali ndi mwayi wolumikizana nawo mofanana ndipo amatha kugwiritsa ntchito mafoni am'manja pamsika, bungwe la Federal Communications Commission ku United States latulutsa chikalata chokambirana, chokonzekera kukwaniritsa 100% yogwirizana ndi zothandizira kumva. (HAC) pa mafoni.
HAC ndi nthawi yamakampani yomwe idawonekera koyamba kumapeto kwa zaka za m'ma 1970. Imodzi mwa njira zogwirira ntchito zothandizira kumva zimadalira izi, zomwe ndizoti kusinthana kwa maginito pazigawo zomveka za foni kumapangitsa kuti zida zomvetsera zipange magetsi opangidwa. Izi zidayambitsa njira yoyesera ya HAC. Mayeso a HAC amafotokoza mayendedwe oyambira amagetsi opangidwa ndi zinthu zomwe zili pafoni yam'manja. Ngati mpenderoyo sikwanira m’bokosilo, zimasonyeza kuti foniyo si yoyenera kwa anthu amene ali ndi vuto lakumva.
Pofika pakati pa zaka za m'ma 1990, zinadziwika kuti mawailesi amtundu wa wailesi pa mafoni a m'manja anali amphamvu, omwe amatha kulepheretsa chizindikiro chomwe chimaperekedwa ndi chipangizo chomveka chothandizira kumva. Chifukwa chake, gulu la maphwando atatu (opanga mafoni opanda mawaya, opanga zothandizira kumva, ndi anthu omwe amamva pang'ono) adakhala pamodzi ndikulemba limodzi ndikupanga IEEE C63.19, yomwe imafotokoza mwatsatanetsatane kuyezetsa kwa ma frequency a radio, kuyesa kwa ma electromagnetic pazida zopanda zingwe. pamenepa, mafoni a m'manja), ndi zina zotero, kuphatikizapo zizindikiro, malingaliro a hardware, masitepe oyesera, mawaya, mfundo zoyesera, etc.
1. Zofunikira za FCC pazida zonse zapamanja ku United States:
Bungwe la Federal Communications Commission (FCC) ku United States likufuna kuti kuyambira pa Disembala 5, 2023, zida zonse zogwira pamanja ziyenera kukwaniritsa zofunikira za ANSI C63.19-2019 muyezo (ie muyezo wa HAC 2019).
Poyerekeza ndi mtundu wakale wa ANSI C63.19-2011 (HAC 2011), kusiyana kwakukulu pakati paziwirizi kwagona pakuwonjezera zofunikira zoyezera voliyumu mu muyezo wa HAC 2019. Zinthu zoyezera voliyumu zimaphatikizanso kupotoza, kuyankha pafupipafupi, komanso kupindula kwa gawo. Zofunikira zoyenera ndi njira zoyesera ziyenera kutsata muyezo wa ANSI/TIA-5050-2018
2.Kodi ndi zinthu ziti zomwe zikuphatikizidwa mu mayeso a HAC kuti zigwirizane ndi zothandizira kumva?
Kuyesa kwa HAC kuti igwirizane ndi zothandizira kumva nthawi zambiri kumaphatikizapo kuyesa kwa RF Rating ndi kuyesa kwa T-Coil. Mayeserowa amafuna kuwunika kuchuluka kwa kusokoneza kwa mafoni a m'manja pazithandizo zamakutu kuti awonetsetse kuti ogwiritsa ntchito zothandizira kumva atha kupeza chidziwitso chomveka bwino komanso chosasokoneza poyankha mafoni kapena kugwiritsa ntchito zida zina zomvera.
Chiphaso cha FCC
Malinga ndi zofunikira zaposachedwa za ANSI C63.19-2019, zofunika pa Volume Control zawonjezedwa. Izi zikutanthauza kuti opanga akuyenera kuwonetsetsa kuti foniyo ikupereka mphamvu zowongolera voliyumu yoyenera mkati mwaogwiritsa ntchito othandizira kumva kuti awonetsetse kuti akumva kuyimba komveka bwino. Zofunikira zapadziko lonse pazoyeserera za HAC:
United States (FCC): FCC eCR Gawo 20.19 HAC
Canada (ISED): RSS-HAC
China: YD/T 1643-2015
3.Pa Epulo 17, 2024, semina ya TCB idasintha zofunikira za HAC:
1) Chipangizocho chiyenera kukhalabe ndi mphamvu yotumizira kwambiri m'makutu mpaka kumakutu.
2) U-NII-5 imafuna kuyesa bandi imodzi kapena zingapo pafupipafupi pa 5.925GHz-6GHz.
3)Kuwongolera kwakanthawi pa 5GNR FR1 frequency band mu KDB 285076 D03 kuchotsedwa mkati mwa masiku 90; Pambuyo pochotsa, ndikofunikira kugwirizana ndi malo oyambira (omwe amafunikira kuthandizira ntchito ya VONR) poyesa kutsimikizira kutsata kwa HAC kwa 5GNR, kuphatikiza zofunikira zowongolera voliyumu.
4) Mafoni onse a HAC akuyenera kulengeza ndikukhazikitsa Waiver PAG molingana ndi chikalata chochotsa Waiver DA 23-914.
BTF Testing Lab, kampani yathu ili ndi ma electromagnetic compatibility laboratories, ma labotale achitetezo, Laboratory yopanda zingwe, Laboratory ya batri, Laboratory ya Chemical, SAR Laboratory, HAC Laboratory, ndi zina zambiri. Tapeza ziyeneretso ndi zilolezo monga CMA, CNAS, CPSC, A2LA, VCCI, ndi zina zotero. Kampani yathu ili ndi gulu lodziwa bwino ntchito zaukadaulo, lomwe lingathandize mabizinesi kuthetsa vutoli. Ngati muli ndi zofunikira zoyezetsa komanso zotsimikizira, mutha kulumikizana mwachindunji ndi ogwira ntchito athu Oyesa kuti mupeze zambiri zamtengo wapatali komanso zambiri zozungulira!
