Hearing Aid Compatibility (HAC) inoreva kugarisana pakati penhare mbozha uye yekubatsira kunzwa kana ichishandiswa panguva imwe chete. Kune vanhu vazhinji vane hurema hwekunzwa, zvinoyamura kunzwa zvishandiso zvakakosha muhupenyu hwavo hwezuva nezuva. Nekudaro, pavanoshandisa mafoni avo, vanowanzo vhiringwa nemagetsi, zvichikonzera kunzwa kusinganzwisisike kana ruzha. Kugadzirisa nyaya iyi, American National Standards Institute (ANSI) yakagadzira mazinga akakodzera ekuyedza uye zvinodiwa zvekuteedzera HAC kuenderana kwezviyamuro zvekunzwa.
MuUnited States, vanhu vanopfuura mamiriyoni 37,5 vanotambura nokusanzwa zvakanaka. Pakati pavo, chikamu che25% chevanhu vane makore makumi matanhatu nemashanu kusvika makumi manomwe nemana vanotambura nekusanzwa zvakanaka, uye chikamu che50% chevakweguru vane makore makumi manomwe nemashanu zvichikwira vanotambura nekuremara kwekunzwa. Kuti ive nechokwadi chekuti vanhu ava vawana masevhisi ekutaurirana zvakaenzana uye vanokwanisa kushandisa nharembozha pamusika, Federal Communications Commission yekuUnited States yakaburitsa gwaro rekubvunzana, kuronga kuwana 100% inoenderana nerubatsiro rwekunzwa. (HAC) panharembozha.
HAC ishoko reindasitiri rakatanga kuoneka mukupera kwema1970. Imwe yemaitiro ekushanda ezviyamuro zvekunzwa inotsamira pane izvi, zvinova zvekuti kuchinjisa magineti ezviridzwa zvefoni zvinokonzeresa zvinoyamura kunzwa kuburitsa induced voltage. Izvi zvakapa nzira yekuyedza yeHAC. Iyo HAC bvunzo inotsanangura yakakosha electromagnetic mhinduro curve inogadzirwa nezvikamu zviri pafoni mbozha. Kana iyo curve isingakwane mukati mebhokisi, inoratidza kuti foni haina kukodzera kune vanhu vane hurema hwekunzwa.
Pakazosvika pakati pemakore ekuma1990, zvakaonekwa kuti nhepfenyuro yeredhiyo panhare mbozha yakanga yakasimba, iyo yaizovhara chiratidzo chakakonzerwa chinodyiswa nemudziyo wezwi kune yamuro yekunzwa. Naizvozvo, boka remapato matatu (vagadziri vemafoni vasina waya, vagadziri vezviyamuro zvekunzwa, uye vanhu vane kunzwa kushoma) vakagara pamwechete uye vakanyora pamwe chete uye vakagadzira IEEE C63.19, iyo yakatsanangudza kuyedzwa kwemaitiro eredhiyo frequency unit, electromagnetic kuyedzwa kwewireless zvishandiso. mune iyi kesi, nharembozha), nezvimwewo, kusanganisira masaini, kurudziro yehardware, matanho ekuyedza, wiring, misimboti yekuyedza, nezvimwe.
1. FCC zvinodiwa pamidziyo yese inobatwa nemaoko muUnited States:
Iyo Federal Communications Commission (FCC) iri muUnited States inoda kuti kutanga kubva Zvita 5, 2023, zvese zvinobatwa nemaoko zvigadziriso zvinofanirwa kuzadzisa zvinodiwa zve ANSI C63.19-2019 standard (kureva iyo HAC 2019 standard).
Kuenzaniswa neiyo yekare vhezheni yeANSI C63.19-2011 (HAC 2011), mutsauko mukuru pakati pezviviri zviri mukuwedzera kwevhoriyamu yekudzora bvunzo zvinodiwa muHAC 2019 standard. Iyo vhoriyamu yekudzora kuyedza zvinhu zvinonyanya zvinosanganisira kukanganisa, frequency mhinduro, uye chikamu kuwana. Zvinodiwa zvinodikanwa uye nzira dzekuyedza dzinoda kureva kune yakajairwa ANSI/TIA-5050-2018.
2.Ndezvipi zvinhu zvinosanganisirwa muyedzo yeHAC yekuenderana nerubatsiro rwekunzwa?
HAC kuyedza kuenderana kwekubatsira kunzwa kunowanzo sanganisira RF Rating kuyedzwa uye T-Coil kuyedzwa. Miedzo iyi ine chinangwa chekuongorora dhigirii rekupindira kwenharembozha pazviyamuro zvekunzwa kuti vaone kuti vashandisi verubatsiro rwekunzwa vanogona kuwana ruzivo rwakajeka uye rwusina kukanganiswa rwekunzwa pakupindura nhare kana kushandisa mamwe mabasa ekuteerera.

Zvinoenderana nezvazvino zvinodiwa zve ANSI C63.19-2019, zvinodiwa zveVolume Control zvawedzerwa. Izvi zvinoreva kuti vagadziri vanofanirwa kuve nechokwadi chekuti foni inopa kudzora vhoriyamu kwakakodzera mukati mekunzwa kwevashandisi vekubatsira kunzwa kuti vaone kuti vanogona kunzwa ruzha rwekufona rwakajeka. Zvinodiwa zvenyika kune HAC yekuyedza zviyero:

3.Musi waKubvumbi 17, 2024, musangano weTCB wakagadziridza zvinodikanwa zveHAC:
1) Chishandiso chinoda kuchengetedza yakanyanya kutapurirana simba munzeve kuenda kune nzeve modhi.
2) U-NII-5 inoda kuyedza rimwe kana kupfuura frequency bhendi pa5.925GHz-6GHz.
3)Nhungamiro yenguva pfupi pa5GNR FR1 frequency bhendi muKDB 285076 D03 ichabviswa mukati memazuva makumi mapfumbamwe; Mushure mekubviswa, zvinodikanwa kushandira pamwe neiyo base station (inoda kutsigira VONR basa) yekuyedza kuratidza kutevedza kweHAC kwe5GNR, kusanganisira kudzora vhoriyamu zvinodiwa.
4) Mafoni ese eHAC anoda kuzivisa uye kuita Waiver PAG zvinoenderana negwaro rekuregererwa Waiver DA 23-914.
BTF Testing Lab, kambani yedu ine electromagnetic inoenderana marabhoritari, kuchengetedza mirau Laboratory, isina waya radio frequency Laboratory, bhatiri Laboratory, Chemical Laboratory, SAR Laboratory, HAC Laboratory, nezvimwewo. VCCI, nezvimwewo Kana iwe uine yakakodzera kuyedzwa uye zvitupa zvinodiwa, unogona kubata zvakananga vashandi vedu Vekuyedza kuti uwane yakadzama mutengo makotesheni uye kutenderera ruzivo!
