I-Hearing Aid Compatibility (i-HAC) ibhekiselele ekusebenzisaneni phakathi kwefowuni ephathwayo kunye nesixhobo sokuva xa sisetyenziswa ngaxeshanye. Kubantu abaninzi abangeva kakuhle, izixhobo zokuva zizixhobo ezibalulekileyo kubomi babo bemihla ngemihla. Nangona kunjalo, xa besebenzisa iifowuni zabo, bahlala bephantsi kokuphazamiseka kwe-electromagnetic, okukhokelela ekungeveni okanye kwingxolo engacacanga. Ukujongana nalo mbandela, i-American National Standards Institute (ANSI) iphuhlise imigangatho yokuvavanya efanelekileyo kunye neemfuno zokuthotyelwa kwe-HAC ehambelanayo yokuncedisa ukuva.
EUnited States, abantu abangaphezu kwezigidi ezingama-37.5 banengxaki yokungeva kakuhle. Phakathi kwabo, malunga ne-25% yabantu abaneminyaka engama-65 ukuya kuma-74 banengxaki yokungeva kakuhle, kwaye malunga ne-50% yabantu abadala abaneminyaka engama-75 nangaphezulu bathwaxwa kukungakwazi ukuva. Ukuze kuqinisekiswe ukuba aba bantu banokufikelela kwiinkonzo zonxibelelwano ngokulinganayo kwaye bayakwazi ukusebenzisa iifowuni eziphathwayo kwiimarike, i-Federal Communications Commission yase-United States ikhuphe idrafti yokubonisana, icwangcisa ukufezekisa i-100% yokuncedisa ukuva. (HAC) kwiifowuni eziphathwayo.
I-HAC ligama leshishini elaqala ukuvela ekupheleni kweminyaka yoo-1970. Enye yeendlela zokusebenza zokuncedisa ukuva zixhomekeke kule nto, kukuba i-magnetic field yezixhobo zesandi zefowuni iya kubangela ukuba izixhobo zokuva zivelise amandla ombane. Oku kubangele indlela yokuvavanya i-HAC. Uvavanyo lwe-HAC luchaza ijiko lempendulo ye-electromagnetic esisiseko eyenziwe ngamalungu kwifowuni ephathwayo. Ukuba ijika alingeni ngaphakathi kwebhokisi, libonisa ukuba ifowuni ayifanelekanga kubantu abangeva kakuhle.
Phakathi kwiminyaka yoo-1990, kwafunyaniswa ukuba umqondiso wefrikhwensi kanomathotholo kwiifowuni eziphathwayo wawunamandla, nto leyo eya kuthi ithintele isignali esenziweyo esondliwa sisixhobo sesandi kwisixhobo sokuva. Ke ngoko, iqela lamaqela amathathu (abavelisi beefowuni abangenazingcingo, abavelisi boncedo lokuva, kunye nabantu abangeva kakuhle) bahlala kunye kwaye bayila ngokudibeneyo kwaye baqulunqa i-IEEE C63.19, echaza iinkcukacha zovavanyo lweeyunithi zamaza kanomathotholo, uvavanyo lwe-electromagnetic yezixhobo ezingenazingcingo. kule meko, iifowuni eziphathwayo), njl., Kubandakanya izibonakaliso, iingcebiso ze-hardware, amanyathelo okuvavanya, i-wiring, imigaqo yokuvavanya, njl.
1. Iimfuno zeFCC kuzo zonke izixhobo zetheminali eziphathwa ngesandla eMelika:
I-Federal Communications Commission (FCC) e-United States idinga ukuba ukususela ngoDisemba 5, 2023, zonke izixhobo ze-terminal terminal kufuneka zihlangabezane neemfuno zomgangatho we-ANSI C63.19-2019 (okt umgangatho we-HAC 2019).
Xa kuthelekiswa nohlobo oludala lwe-ANSI C63.19-2011 (HAC 2011), umahluko omkhulu phakathi kwezi zibini zilele ukongezwa kweemfuno zovavanyo lokulawula umthamo kwi-HAC 2019 standard. Izinto zovavanyo lolawulo lwevolumu ikakhulu zibandakanya ukuphazamiseka, ukuphendula rhoqo, kunye nokuzuza kweseshoni. Iimfuno ezifanelekileyo kunye neendlela zokuvavanya kufuneka zibhekiselele kumgangatho we-ANSI/TIA-5050-2018.
2.Ziziphi izinto ezibandakanyiweyo kuvavanyo lwe-HAC lokuhambelana noncedo lokuva?
Uvavanyo lwe-HAC lokuhambelana koncedo lokuva lubandakanya uvavanyo lwe-RF yokuHlola kunye novavanyo lwe-T-Coil. Ezi mvavanyo zijolise ekuvavanyeni iqondo lokuphazamiseka kweefowuni eziphathwayo kwizixhobo zokuva ukuze kuqinisekiswe ukuba abasebenzisi bokuncedisa ukuva banokufumana amava acacileyo kunye nokuphazamiseka kokuva xa bephendula iifowuni okanye besebenzisa eminye imisebenzi yomsindo.
Isiqinisekiso seFCC
Ngokweemfuno zamva nje ze-ANSI C63.19-2019, iimfuno zoLawulo loMqulu ziye zongezwa. Oku kuthetha ukuba abavelisi kufuneka baqinisekise ukuba ifowuni ibonelela ngokulawula umthamo ofanelekileyo ngaphakathi kwendawo yokuva yabasebenzisi bokuncedisa ukuva ukuqinisekisa ukuba banokuva izandi ezicacileyo zokufowuna. Iimfuno zeSizwe zemigangatho yovavanyo lwe-HAC:
eUnited States (FCC): FCC eCR Icandelo 20.19 HAC
EKhanada (IED): RSS-HAC
China: YD/T 1643-2015
3.Ngomhla we-17 ku-Epreli, 2024, isemina ye-TCB yahlaziywa iimfuno ze-HAC:
1) Isixhobo kufuneka sigcine amandla aphezulu okuhambisa kwimowudi yendlebe ukuya kwindlebe.
2) U-NII-5 ifuna ukuvavanya enye okanye ngaphezulu band frequency kwi 5.925GHz-6GHz.
3)Isikhokelo sexeshana kwi-5GNR FR1 band frequency kwi-KDB 285076 D03 iya kususwa phakathi kweentsuku ezingama-90; Emva kokususwa, kuyimfuneko ukusebenzisana nesikhululo sesiseko (esidinga ukuxhasa umsebenzi we-VONR) ukuvavanya ukubonisa ubungqina bokuthotyelwa kwe-HAC ye-5GNR, kubandakanywa neemfuno zokulawula umthamo.
4)Zonke iifowuni ze-HAC kufuneka zibhengeze kwaye ziqhube i-Waiver PAG ngokuhambelana noxwebhu loxolelo lwe-Waiver DA 23-914.
ILebhu yoVavanyo lwe-BTF, inkampani yethu ineelabhoratri ezihambelanayo ne-electromagnetic, imimiselo yokhuseleko ILabhoratri, iLebhu yerediyo engenazingcingo, iLebhu yebhetri, iLebhu yeekhemikhali, iLabhoratri yeSAR, iLabhoratri ye-HAC, njl.
