M'nkhani yathu yokweza, anthu ambiri amakayikira: KodiZithunzi za TWSotetezeka?Kodi zomverera m'makutu zopanda zingwe ndizowopsa?Monga adapeza kuti kuchokera ku ma router a Wi-Fi, zida zam'manja, kapena zowunikira ana.Kuchulukana kochokera ku zonse zomwe zatizungulira ndizomwe zimawonjezera chiwopsezo cha thanzi la munthu kuposa chida chilichonse.
Bwererani kumakutu opanda zingwe.Palibe umboni wotsimikizirika woti iwo ndi owopsa kwa anthu popeza palibe kafukufuku wokhudzana ndi nthawi yayitali ya mahedifoni opanda zingwe omwe apangidwa.Pali kusagwirizana pakati pa akatswiri ponena za kukula kwa zotsatira zake zoipa.Ngakhale ena akufuna kuti malamulo okhwima akhazikike, ena amaganiza kuti zodetsa nkhawa ndizokokomeza ndipo EMF yochokera m'makutu ndi yofooka kwambiri kuti isakhudze thupi la munthu, kutanthauza kuti mutha kunyalanyaza kukopa kwawo.Izi ndi zomwe anthu ambiri amaganiza.
Pakalipano, izi ndi zimene United States Federal Communications Commission (FCC) ikunena ponena za zipangizo zamawaya ndi thanzi lanu: “Pakadali pano palibe umboni wa sayansi umene umasonyeza kugwirizana pakati pa kugwiritsa ntchito zipangizo zamawaya ndi khansa kapena matenda ena.
Tili ndi nkhani zomwe zimakuwonetsani:Kodi kugwiritsa ntchito TWS ndi chiyani?ndi kufotokoza Kodi TWS (zoona stereo) yopanda zingwe ndi chiyani.
Kwenikweni, popeza ndi mtundu wa EMF wopanda ionizing, Bluetooth nthawi zambiri imakhala yotetezeka kwa anthu, ndipo siyikhudza thanzi lathu.M'malo mwake, Bluetooth ili ndi milingo yotsika kwambiri (SAR), kutsimikiziranso kuti sizowopsa kwa anthu.Kupatula apo, Radiation imayambitsa khansa koma si mitundu yonse ya ma radiation yomwe ingathe kutero, makamaka omwe amachokera ku mahedifoni kapena m'makutu.Chomwe chimathandizidwa kwambiri chowononga kuchokera ku EMR yopanda ionizing m'makutu ndikutentha chabe, komwe kumatha kukhala kowopsa pamilingo yayikulu.
Kodi EMF ndi RF ndi chiyani?
EMF imayimira ElectroMagnetic Field ndipo RF imayimira Radio Frequency.EMFs ndi mafunde apafupi (osati amphamvu) omwe amatuluka kuchokera kuzipangizo monga foni yam'manja yomwe ili m'thumba mwanu kapena mahedifoni opanda zingwe.Amatha kuyezedwa ndi mita ya gauss ndi muyeso wake.
Ma RF, kumbali ina, ndi mafunde a electromagnetic okhala ndi utali wautali kuposa ma radiation ya microwave ndipo nthawi zambiri amachokera ku zida zamagetsi monga ma TV, ndi ma microwave kutchula zitsanzo ziwiri zokha komanso mahedifoni opanda zingwe amawatulutsa.
M'malingaliro mwake, kugwiritsa ntchito ma speaker kapena ma Bluetooth m'makutu opanda zingwe m'malo moyankha foni yanu mwachindunji ndikotetezeka kuposa kugwiritsa ntchito mlongoti wa foni yam'manja.
Ngakhale mungamve mabungwe ena olemekezeka akunena kuti mafunde a Bluetooth ndi owopsa, muyenera kuganiziranso magulu osiyanasiyana a Bluetooth kuti muwone ngati mafundewa ali ndi kuthekera kosintha DNA.
Bluetooth ikhoza kugawidwa m'magulu atatu -
Kalasi 1 - zida zamphamvu kwambiri za Bluetooth zimagwera pansi pa kalasi iyi.Zidazi zimatha kukhala ndi kutalika kwa 300 mapazi (~ 100 metres) ndipo zimagwira ntchito mwamphamvu kwambiri 100 mW.
Kalasi 2 - imodzi mwamagulu wamba a Bluetooth omwe amapezeka pazida zosiyanasiyana.Imatha kutumiza deta pa 2.5 mW pamtunda wa 33 mapazi (~ 10 metres).
Kalasi 3 -zida zocheperako zaukadaulo za Bluetooth zili m'gululi.Zida zotere zimakhala ndi kutalika kwa 3 mapazi (~ 1 mita) ndipo zimagwira ntchito pa 1 mW.
Pakati pa magulu osiyanasiyana a Bluetooth awa, zida zamtundu wa 3 za Bluetooth ndizovuta kwambiri kuzipeza masiku ano.Kumbali inayi, mutha kuwona mosavuta zida zambiri zamtundu wa 2 komanso kuchuluka kwa zida za kalasi 1 kuzungulira.
Bluetooth ndi SAR
Kupatula magulu atatu a Bluetooth ndi ma frequency ndi mphamvu zake zosiyanasiyana, chinthu chinanso chomwe chiyenera kuganiziridwanso ndi mtengo wa SAR.SAR kapena Specific Absorption Rate ndi muyeso wa kuchuluka kwa mphamvu zomwe thupi la munthu limatengera ndi EMF (RF).Mtengowu umathandizira kudziwa kuchuluka kwa mphamvu zomwe zimatengedwa ndi thupi (ndi mutu) pa unyinji wa minofu.Nthawi zambiri, mtengo wa SAR pa mahedifoni am'manja a Bluetooth ndi pafupifupi 0.30 watts pa kilogalamu, zomwe zimagwera pansi pa malangizo a FCC (Federal Communications Commission) omwe amalimbikitsa kuti chipangizo chisakhale ndi mtengo wopitilira 1.6 watts pa kilogalamu.Kuti ndikupatseni chitsanzo, imodzi mwamakutu otchuka opanda mawaya, Apple AirPods, ili ndi mtengo wa SAR wa 0.466 watts pa kilogalamu, zomwe zili pansi pa malire omwe aperekedwa ndi FCC.
Kusamala mukamagwiritsa ntchito makutu a TWS opanda zingwe:
-Nazi zingapo zomwe mungachite kuti muchepetse ngozi mukamagwiritsa ntchito zomvera m'makutu:
-Osagwiritsa ntchito mahedifoni opanda zingwe kwa nthawi yayitali.
- Chepetsani kugwiritsa ntchito foni yam'manja ndikuyiyika kutali / ndege ikakhala yosagwiritsidwa ntchito kapena pa speaker mode kuti muchepetse kuwonekera kwa radiation ya EMF.
-Ngati mukufuna mahedifoni opanda zingwe a Bluetooth, onetsetsani kuti ali m'malire a FCC.
-Mukamagwiritsa ntchito mahedifoni opanda zingwe, zimitsani Bluetooth pomwe siyikugwira ntchito.Osawalola kukhala opanda pake.
Kumaliza ndi kuyankha funso - kodi Bluetooth ndi yotetezeka kapena ayi - chinthu chimodzi chomwe chiyenera kukumbukiridwa ndi chakuti, popeza palibe maphunziro okwanira otsimikizira kuti kuwala kwa Bluetooth kungayambitse kuwonongeka kwa DNA (ndipo, kumayambitsa mavuto aakulu a thanzi). ), munthu ayenera kupewa kuzunguliridwa mwakhungu ndi zida za Bluetooth nthawi zonse.Panthawi imodzimodziyo, sayenera kuda nkhawa kuti agwiritse ntchito zipangizozi mpaka atayang'aniridwa.Masiku ano, sizingatheke kuti anthu ena asiye zipangizozi kwathunthu.Kupatula apo, omwe atha kutengera kusadalira / kugwiritsa ntchito zida za Bluetooth (zomvera m'makutu, mwachitsanzo), atha kuyesa mahedifoni apamutu m'malo mwake kuti achepetse kukhudzidwa kwawo ndi ma radiation a Bluetooth.
Tilibebe chidziwitso chotsimikizika kuti timvetsetse zoopsa zomwe zingachitike koma tachokera kutali ndi sayansi ndipo tikuphunzira zatsopano nthawi zonse.Njira zingapo zodzitetezera zitha kuthandizira kwambiri kuchepetsa kukhudzidwa kwa ma radiation kuchokera pazida zopanda zingwe kotero ndikofunikira kukumbukira izi mukamagwiritsa ntchito ukadaulo.
Wellepmonga akatswiri ogulitsa makutu am'makutu, ngati muli ndi mafunso enanso okhudza ma tws earbuds, chonde khalani omasukaLumikizanani nafe.Zikomo!
