Ngophuhliso lwetekhnoloji yolwazi, uluntu luya luxhalaba malunga nefuthe lemitha ye-electromagnetic evela kwiitheminali zonxibelelwano ezingenazingcingo kwimpilo yabantu, kuba iiselfowuni kunye neetafile ziye zaba yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, nokuba kukugcina ukunxibelelana nabantu esibathandayo. abo, hlala unxibelelana nomsebenzi, okanye ukuzonwabisa nje endleleni, ezi zixhobo ziye zayiguqula ngokwenene indlela yethu yokuphila. Ngoko ke kubalulekile ukuqiniseka ukuba ezi zixhobo zisebenziseka lula kwaye zikhuselekile ukuzisebenzisa. Kulapho i-lab yovavanyo ye-BTF kunye nobuchule bayo kwi-SAR, i-RF, i-T-Coil kunye ne-Volume control test idlala.
Uvavanyo lwe-SAR (izinga elithile lokufunxa) lenzelwe ikakhulu izixhobo eziphathwayo, ezinjengeefowuni eziphathwayo, iitafile, iiwotshi kunye neelaptops, njl. njl. Ilebhu yethu yovavanyo lwe-BTF igxile kuvavanyo lwe-SAR kwaye ixhotyiswe ngokupheleleyo ukuhlangabezana neemfuno zendawo yovavanyo, kunye nokuqinisekisa ukuba isixhobo siyayithobela imida yokhuseleko ebekwe ngabasemagunyeni abalawulayo. Ngokuqhuba uvavanyo lwe-SAR, abavelisi banokuqinisekisa ukuba iimveliso zabo azibeki mngcipheko wezempilo kubasebenzisi.
| Isikhundla somzimba | Ixabiso le-SAR (W/Kg) | |
| Inani labemi ngokubanzi/Ukutyhileka okungalawulwayo | Ukutyhileka koMsebenzi/okulawulwayo | |
| Umzimba wonke we-SAR (umndilili womzimba wonke) | 0.08 | 0.4 |
| I-SAR yoMzimba ongaQekanga (umndilili we-1 gram yethishu) | 2.0 | 10.0 |
| I-SAR yezandla, izihlahla, iinyawo kunye namaqatha (i-avareji ngaphezu kwayo nayiphi na i-10 grams yethishu) | 4.0 | 20.0 |
| QAPHELA:Abemi Jikelele/UMtyhilelo olungaLawulwayo: Iindawo apho kukho ukuvezwa kwabantu abangenalwazi okanye ulawulo lokuvezwa kwabo. Imida yokuvezwa kwabantu ngokubanzi/ engalawulwayo isetyenziswa kwiimeko apho uluntu ngokubanzi lunokuthi lube sesichengeni okanye apho abantu abavezwe ngenxa yengqesho yabo banokuthi bangabi nalwazi ngokupheleleyo malunga nokuba sesichengeni okanye bangakwazi ukulawula ukuba sesichengeni kwabo. Amalungu oluntu ngokubanzi angangena phantsi kolu didi xa ukuvezwa kunganxulumenanga nengqesho; umzekelo, kwimeko yesisasazo esingenazingcingo esiveza abantu abakummandla waso.Ukutyhileka okuLawulwayo emsebenzini/okulawulwayo: Iindawo apho utyhileko olunokuthi lwenziwe ngabantu abawaziyo amathuba okuba sesichengeni, Ngokubanzi, imida yokuvezwa emsebenzini/elawulwayo. zisebenza kwiimeko apho abantu bavezwa khona ngenxa yengqesho yabo, abaye benziwa ukuba baqonde ngokupheleleyo ukuba sesichengeni okunokwenzeka kwaye banokulawula ukuba sesichengeni sabo. Olu didi lokuvezwa lukwasebenza xa ukutyhileka kuyindalo yexeshana ngenxa yokudlula ngendlela engalindelekanga kwindawo apho amanqanaba okuvezwa anokuba phezulu kunoluntu ngokubanzi/imida engalawulekiyo, kodwa umntu obhengeziweyo uyazi ngokupheleleyo ukubanakho ukutyhileka kwaye unako. sebenzisa ukulawula ukuvezwa kwakhe ngokushiya indawo okanye ngezinye iindlela ezifanelekileyo. | ||
Itshathi yovavanyo lweSAR
I-Hearing Aid Compatibility (HAC) Esi sisiqinisekiso sokuba iiselfowuni zedijithali aziyi kuphazamisa ukuva okukufutshane kwe-AIDS phambi konxibelelwano, oko kukuthi, ukuvavanya ukuhambelana kwe-electromagnetic yeefowuni eziphathwayo kunye nokuva i-AIDS, eyahlulahlulwe yangamacandelo amathathu: RF, T- coil kunye Volume uvavanyo lolawulo. Kufuneka sivavanye kwaye sivavanye amaxabiso amathathu, ixabiso lokuqala kukuxinana kwemagnethi yesiginali yenjongo (isiginali yenkqubo) kumbindi wokuphindaphindeka kwebhendi yefrikhwensi yomsindo, ixabiso lesibini kukuphendula okuphindaphindiweyo kophawu lwangabom phezu komsindo wonke. i-frequency band, kunye nexabiso lesithathu ngumahluko phakathi kwamandla kazibuthe yesiginali yenjongo (uphawu lwenkqubo) kunye nomqondiso ongeyonjongo (uphawu lokuphazamiseka). Umgangatho wesalathiso we-HAC yi-ANSI C63.19 (iNdlela yoMgangatho weSizwe wokulinganisa ukuhambelana kwezixhobo zonxibelelwano ezingenazintambo kunye ne-AIDS yokuva e-United States), ngokubhekiselele apho umsebenzisi achaza ukuhambelana kohlobo oluthile lokuncedisa ukuva kunye neselula. ifowuni ngokusebenzisa inqanaba lokuchasana nokuphazamiseka kokuncedisa ukuva kunye nenqanaba lokukhutshwa kwesignali yeselula ehambelanayo.
Yonke inkqubo yovavanyo lwenziwa ngokulinganisa kuqala amandla emagnethi kwibhanti yefrikhwensi yomsindo eluncedo kwi-T-coil yokuncedisa ukuva. Inyathelo lesibini lilinganisa icandelo lemagnethi yesignali engenazingcingo ukumisela isiphumo semiqondiso engabom kwibhendi yefrikhwensi yomsindo, njengokuboniswa kwesixhobo sonxibelelwano esingenazingcingo kunye nendlela yangoku yebhetri. Uvavanyo lwe-HAC lufuna ukuba umda wefowuni ephathwayo evavanyiweyo yi-M3 (isiphumo sovavanyo sahlulwe sibe yi-M1~M4). Ukongeza kwi-HAC, i-T-coil (uvavanyo lomsindo) kufuneka kwakhona ifune umda kwi-T3 (iziphumo zovavanyo zihlulwe zibe yi-T1 ukuya kwi-T4).

Itshathi yovavanyo lweRF kunye neT-coil
Ngokudibanisa ubuchule belebhu yethu yovavanyo lwe-BTF kunye nenkqubela phambili kwitekhnoloji yefowuni ephathwayo kunye nethebhulethi, abavelisi banokuvelisa izixhobo ezingaboneleli nje ngamava angenamthungo omsebenzisi kodwa ezihlangabezana nayo yonke imigangatho yokhuseleko. Intsebenziswano phakathi kwelebhu yovavanyo ye-BTF kunye nomenzi iqinisekisa ukuba isixhobo sivavanyelwe i-SAR, i-RF, i-T-Coil kunye nokuthotyelwa kokulawula umthamo.
