Mu buku lathu lolembamo zinthu zakale, anthu ambiri amakayikira kuti: KodiMahedifoni ang'onoang'ono a TWSKodi ma earbuds opanda zingwe ndi oopsa? Monga momwe adapezera kuchokera ku ma router a Wi-Fi, zida zam'manja, kapena ma baby monitors. Kuchulukana kwa zinthu zonse zomwe zili mkati mwathu ndi komwe kumawonjezera chiopsezo cha thanzi la anthu kuposa chipangizo chilichonse.
Kubwerera kumahedifoni opanda zingwe a twsPalibe umboni wotsimikizika wakuti ndi owopsa kwa anthu chifukwa palibe kafukufuku wokhudza zotsatira za mahedifoni opanda zingwe zomwe zachitika kwa nthawi yayitali. Pali kusagwirizana pakati pa akatswiri pankhani ya kuchuluka kwa zotsatira zake zoyipa. Ngakhale ena akupempha malamulo okhwima, ena akuganiza kuti nkhawazo ndi zokokomeza ndipo EMF yachokera kumakutundi yofooka kwambiri moti singakhudze thupi la munthu, zomwe zikutanthauza kuti mutha kunyalanyaza mphamvu zake. Iyi ndi lingaliro lofala masiku ano.
Pakadali pano, izi ndi zomwe bungwe la United States Federal Communications Commission (FCC) likunena zokhudza zipangizo zopanda zingwe ndi thanzi lanu: “Pakadali pano palibe umboni wa sayansi womwe umatsimikizira mgwirizano pakati pa kugwiritsa ntchito zipangizo zopanda zingwe ndi khansa kapena matenda ena.
Tili ndi nkhani zomwe zimakuwonetsani:Kodi kugwiritsa ntchito TWS n'chiyani?ndi kufotokoza Kodi ukadaulo wa TWS (kwenikweni stereo yopanda zingwe) ndi chiyani?
Ndipotu, popeza ndi mtundu wa EMF yosapanga ma ion, Bluetooth nthawi zambiri imakhala yotetezeka kwa anthu, ndipo sidzakhudza thanzi lathu. Ndipotu, Bluetooth ili ndi kuchuluka kochepa kwa ma absorption rate (SAR), zomwe zimatsimikiziranso kuti si yoopsa kwa anthu. Kupatula apo, radiation imayambitsa khansa koma si mitundu yonse ya ma radiation yomwe ingachite izi, makamaka yomwe imachokera ku mahedifoni kapena ma earbuds. Chifukwa china chodziwika bwino cha kuwonongeka kwa ma EMR osapanga ma ion mu mahedifoni ndi kutentha kokha, komwe kungakhale koopsa pamlingo wapamwamba.
Kodi EMF ndi RF ndi chiyani?
EMF imayimira ElectroMagnetic Field ndipo RF imayimira Radio Frequency. Ma EMF ndi mafunde apafupi (osati amphamvu kwambiri) omwe amachokera ku zipangizo monga foni yam'manja yomwe ili m'thumba mwanu kapena mahedifoni opanda zingwe. Amatha kuyezedwa ndi gauss meter ndi muyeso wake.
Kumbali inayi, ma RF ndi mafunde amagetsi okhala ndi kutalika kwa nthawi yayitali kuposa ma radiation a microwave ndipo nthawi zambiri amachokera ku zida zamagetsi monga ma TV, ndi ma microwave kungotchula zitsanzo ziwiri zokha koma mahedifoni opanda zingwe amawatulutsa.
Mwachidule, kugwiritsa ntchito sipika kapena ma Bluetooth opanda zingwe m'malo moyankha foni yanu mwachindunji ndikotetezeka kwambiri kuposa kugwiritsa ntchito antenna ya foni yam'manja.
Ngakhale mungamve mabungwe ena odziwika bwino akunena kuti mafunde a Bluetooth ndi oyambitsa khansa, muyeneranso kuganizira mitundu yosiyanasiyana ya Bluetooth kuti muwone ngati mafundewa ali ndi mphamvu yosintha DNA.
Bluetooth ikhoza kugawidwa m'magulu atatu —
Gulu 1 - zida zamphamvu kwambiri za Bluetooth zili pansi pa gulu ili. Zipangizozi zimatha kukhala ndi mtunda woposa mamita 100 ndipo zimagwira ntchito pa mphamvu yoposa 100 mW.
Gulu lachiwiri - limodzi mwa magulu odziwika bwino a Bluetooth omwe amapezeka pazida zosiyanasiyana. Limatha kutumiza deta pa 2.5 mW pamtunda wa pafupifupi mamita 10.
Gulu 3 - zipangizo zaukadaulo za Bluetooth zomwe ndi zamphamvu kwambiri ndi za gulu ili. Zipangizo zoterezi zimakhala ndi kutalika kwa mamita pafupifupi 1 ndipo zimagwira ntchito pa 1 mW.
Pakati pa makalasi osiyanasiyana a Bluetooth, zipangizo za Bluetooth za kalasi 3 ndizo zovuta kwambiri masiku ano. Kumbali ina, mutha kuwona mosavuta zida zambiri za kalasi 2 komanso zida zambiri za kalasi 1.
Bluetooth ndi SAR
Kupatula magulu atatu a Bluetooth ndi ma frequency ndi mphamvu zawo zosiyanasiyana, chinthu china chomwe chiyenera kuganiziridwanso ndi mtengo wa SAR. SAR kapena Specific Absorption Rate ndi muyeso wa liwiro lomwe mphamvu imayamwa ndi thupi la munthu likakumana ndi EMF (RF). Mtengowu umathandiza kudziwa kuchuluka kwa mphamvu yomwe imayamwa ndi thupi (ndi mutu) pa unyinji wa minofu. Kawirikawiri, mtengo wa SAR wa mahedifoni a Bluetooth wamba ndi pafupifupi 0.30 watts pa kilogalamu, zomwe zimagwirizana bwino ndi malangizo a FCC (Federal Communications Commission) omwe akusonyeza kuti chipangizocho sichiyenera kukhala ndi mtengo woposa 1.6 watts pa kilogalamu. Mwachitsanzo, imodzi mwa mahedifoni otchuka opanda zingwe, Apple AirPods, ili ndi mtengo wa SAR wa 0.466 watts pa kilogalamu, womwe uli pansi pa malire omwe FCC imanena.
Chenjezo mukamagwiritsa ntchito ma waya a TWS earbuds:
Nazi zinthu zingapo zomwe mungachite kuti muchepetse chiopsezo mukamagwiritsa ntchito mahedifoni:
-Musagwiritse ntchito mahedifoni opanda zingwe kwa nthawi yayitali.
-Chepetsani kugwiritsa ntchito foni yanu yam'manja ndikuyiyika patali/plane mode pamene simukugwiritsa ntchito kapena pa sipika mode kuti muchepetse kuwonekera kwa EMF radiation.
-Ngati mukufuna mahedifoni a Bluetooth opanda zingwe, onetsetsani kuti ali mkati mwa malire a FCC.
-Mukamagwiritsa ntchito mahedifoni opanda zingwe, zimitsani Bluetooth ngati sikugwiritsidwa ntchito. Musalole kuti agwire ntchito.
Pomaliza ndikuyankha funso lakuti —kodi Bluetooth ndi yotetezeka kapena ayi — chinthu chimodzi chomwe chiyenera kukumbukiridwa ndichakuti, popeza palibe maphunziro okwanira otsimikizira kuti kuwala kwa Bluetooth kungayambitse kuwonongeka kwa DNA (ndipo, kumayambitsa mavuto aakulu azaumoyo), munthu ayenera kupewa kukhala wozunguliridwa ndi zipangizo za Bluetooth nthawi zonse. Nthawi yomweyo, sayenera kuda nkhawa kuti agwiritse ntchito zipangizozi mpaka zitathetsedwa. Masiku ano, sizingatheke kuti anthu ena asiye zipangizozi kwathunthu. Kupatula apo, iwo omwe angasankhe kusadalira/kugwiritsa ntchito zipangizo za Bluetooth (monga mahedifoni), akhoza kuyesa mahedifoni a air tube m'malo mwake kuti achepetse kukhudzidwa ndi kuwala kwa Bluetooth.
Sitikudziwabe zomwe zingachitike koma tapita patsogolo kwambiri ndi sayansi ndipo tikuphunzira zinthu zatsopano nthawi zonse. Zinthu zingapo zodzitetezera zingathandize kwambiri kuchepetsa kukhudzana ndi kuwala kwa dzuwa kuchokera ku zipangizo zopanda zingwe, choncho ndikofunikira kukumbukira izi mukamagwiritsa ntchito ukadaulo.
