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. Yilapho i-lab yokuhlola i-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) | |
| Abemi ngokubanzi/ Ukutyhileka okungalawulwayo | Umsebenzi/ Ukutyhileka okulawulwayo | |
| Umzimba wonke we-SAR (i-avareji emzimbeni wonke) | 0.08 | 0.4 |
| Inxalenye yoMzimba weSAR (umndilili phezu kwayo nayiphi na igram e-1 yethishu) | 2.0 | 10.0 |
| I-SAR yezandla, izihlahla, iinyawo kunye namaqatha (umndilili we-10 grams yethishu) | 4.0 | 20.0 |
| PHAWULA: Inani labemi ngokubanzi/Ukutyhileka okungalawulwayo: 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 yesithuthi esingenazingcingo esiveza abantu abakummandla waso.
Ukutyhileka eMsebenzini/okulawulwayo: Iindawo apho kukho ukutyhileka okunokuthi kwenzeke ngabantu abanolwazi ngamathuba okuba sesichengeni, Ngokubanzi, imida yokutyhileka emsebenzini/elawulwayo isetyenziswa kwiimeko apho abantu bavezwa khona ngenxa yengqesho yabo, aba baye benziwa ukuba baqonde ngokupheleleyo ukubanakho ukuvezwa 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. | ||
Uvavanyo lwe-HAC Imida yoVavanyo
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.
Itshathi yovavanyo lweSAR
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).

| M1 | 50 ukuya ku-55 dB (V/m) | 40 ukuya ku-45 dB (V/m) |
| M2 | 45 ukuya ku-50 dB (V/m) | 35 ukuya ku-40 dB (V/m) |
| M3 | 40 ukuya ku-45 dB (V/m) | 30 ukuya ku-35 dB (V/m) |
| M4 | < 40 dB (V/m) | < 30 dB (V/m) |
Iindidi zenqanaba lophazamiseko lwe-RFWD RF kwiiyunithi zelogarithmic
| Udidi | Iiparamitha zomnxeba umgangatho wophawu lweWD [(umqondiso + ingxolo) – ukuya – umlinganiselo wengxolo kwiidecibels] |
| Udidi T1 | 0 dB ukuya 10 dB |
| Udidi T2 | 10 dB ukuya ku-20 dB |
| Udidi T3 | 20 dB ukuya 30 dB |
| Udidi T4 | > 30 dB |
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 zihlangabezana nayo yonke imigangatho yokhuseleko. Intsebenziswano phakathi kwelebhu yovavanyo lwe-BTF kunye nomenzi iqinisekisa ukuba isixhobo sivavanyelwe i-SAR, i-RF, i-T-Coil kunye nokuthotyelwa kokulawula umthamo.
