Hauv peb qhov chaw khaws cia, cov neeg feem coob muaj qhov tsis ntseeg: YogTWS earbudsnyab xeeb?Puas yog lub mloog pob ntseg wireless puas tsim kev puas tsuaj?Raws li lawv pom tias los ntawm Wi-Fi routers, mobile devices, lossis tus menyuam saib xyuas.Qhov cuam tshuam los ntawm txhua yam uas nyob ib puag ncig peb yog qhov ua rau muaj kev pheej hmoo rau tib neeg kev noj qab haus huv ntau dua li ib qho khoom siv.
Rov qab mus rau lub wireless earbuds.Tsis muaj pov thawj tseeb tias lawv ua rau tib neeg muaj kev phom sij vim tsis muaj kev tshawb fawb txog kev cuam tshuam ntev ntawm lub mloog pob ntseg wireless tau ua.Muaj kev tsis sib haum xeeb ntawm cov kws tshaj lij txog qhov ntawm lawv qhov tsis zoo.Txawm hais tias qee tus tau thov rau cov cai nruj dua, lwm tus xav tias qhov kev txhawj xeeb yog exaggerated thiab EMF los ntawm pob ntseg tsis muaj zog heev kom muaj kev cuam tshuam rau tib neeg lub cev, txhais tau tias koj tuaj yeem tsis quav ntsej lawv lub zog.Qhov no yog tam sim no txoj kev xav.
Txog tam sim no, ntawm no yog qhov United States Federal Communications Commission (FCC) hais txog cov khoom siv wireless thiab koj txoj kev noj qab haus huv: "Tam sim no tsis muaj pov thawj kev tshawb fawb tsim kom muaj kev sib txuas ntawm kev siv wireless thiab mob qog noj ntshav lossis lwm yam mob.
Peb muaj xov xwm uas qhia rau koj:Qhov twg siv TWS?thiab piav qhia Dab tsi yog TWS (tseeb wireless stereo) thev naus laus zis.
Qhov tseeb, txij li nws yog hom tsis-ionizing EMF, Bluetooth feem ntau muaj kev nyab xeeb rau tib neeg, thiab yuav tsis cuam tshuam rau peb txoj kev noj qab haus huv.Qhov tseeb, Bluetooth muaj qhov tshwj xeeb nqus tus nqi (SAR) qib, ua pov thawj ntxiv tias nws tsis txaus ntshai rau tib neeg.Tsis tas li ntawd, Radiation ua rau mob qog noj ntshav tab sis tsis yog txhua hom hluav taws xob tuaj yeem ua tau, tshwj xeeb tshaj yog cov uas tuaj ntawm lub mloog pob ntseg lossis pob ntseg.Ib qho kev txhawb nqa ntau ntxiv ntawm kev puas tsuaj los ntawm tsis-ionizing EMR hauv lub mloog pob ntseg tsuas yog cua sov, uas tuaj yeem ua rau muaj kev phom sij ntawm qib siab.
EMF thiab RF yog dab tsi?
EMF sawv cev rau ElectroMagnetic Field thiab RF stands rau Xov Tooj Cua Frequency.EMFs yog nyob ze-tsawg (tsis muaj zog) nthwv dej uas tawm ntawm cov khoom siv xws li xov tooj ntawm tes hauv koj lub hnab tshos lossis lub mloog pob ntseg wireless.Lawv tuaj yeem ntsuas los ntawm gauss meter thiab nws chav ntsuas.
RFs, ntawm qhov tod tes, yog lub tshuab hluav taws xob nrog lub wavelength ntev dua li cov hluav taws xob microwave thiab lawv feem ntau tawm ntawm cov khoom siv hluav taws xob xws li TVs, thiab microwaves rau npe tsuas yog ob qho piv txwv tab sis kuj wireless headphones emit lawv.
Hauv txoj kev xav, siv hom hais lus lossis Bluetooth wireless earbuds es tsis txhob teb koj lub xov tooj ncaj qha yog txoj kev nyab xeeb dua li siv lub xov tooj ntawm tes.
Txawm hais tias koj tuaj yeem hnov ib lub koom haum saib xyuas hais tias Bluetooth nthwv dej yog carcinogenic, koj yuav tsum tau ua tib zoo xav txog cov chav sib txawv ntawm Bluetooth kom pom tias cov nthwv dej no puas muaj peev xwm hloov DNA.
Bluetooth tuaj yeem muab faib ua peb chav kawm -
Chav Kawm 1 - cov khoom siv Bluetooth muaj zog tshaj plaws poob rau hauv chav kawm no.Cov cuab yeej no tuaj yeem muaj ntau tshaj 300 ko taw (~ 100 meters) thiab ua haujlwm ntawm lub zog siab tshaj plaws ntawm 100 mW.
Chav Kawm 2 - ib qho ntawm cov chav kawm ntawm Bluetooth pom nyob thoob plaws ntau yam khoom siv.Nws muaj peev xwm xa cov ntaub ntawv ntawm 2.5 mW tshaj li ntawm ib ncig ntawm 33 ko taw (~ 10 meters).
Chav Kawm 3 - cov cuab yeej siv Bluetooth uas muaj zog tshaj plaws yog nyob rau hauv chav kawm no.Cov khoom siv no muaj qhov ntev ntawm 3 ko taw (~ 1 meter) thiab ua haujlwm ntawm 1 mW.
Ntawm cov chav kawm Bluetooth sib txawv no, chav kawm 3 Bluetooth li yog qhov nyuaj tshaj plaws los nrhiav hnub no.Ntawm qhov tod tes, koj tuaj yeem pom tau yooj yim ntau ntawm cov khoom siv hauv chav kawm 2 thiab kuj muaj qhov ncaj ncees ntawm chav kawm 1 cov khoom siv nyob ib puag ncig.
Bluetooth thiab SAR
Dhau li ntawm peb chav kawm Bluetooth thiab lawv qhov sib txawv ntawm kev khiav hauj lwm zaus thiab lub zog, lwm qhov tseem ceeb uas yuav tsum tau muab rau hauv kev txiav txim siab yog tus nqi SAR.SAR lossis Specific Absorption Rate yog qhov ntsuas ntawm tus nqi uas lub zog nqus los ntawm tib neeg lub cev thaum raug. EMF (RF).Tus nqi pab txiav txim siab npaum li cas ntawm lub zog nqus los ntawm lub cev (thiab lub taub hau) ib qho ntawm cov ntaub so ntswg.Feem ntau, SAR tus nqi rau ib khub ntawm Bluetooth lub mloog pob ntseg yog nyob ib ncig ntawm 0.30 watts ib kilogram, uas poob zoo raws li FCC (Tsoomfwv Teb Chaws Kev Sib Txuas Lus Commission) cov lus qhia uas qhia tias lub cuab yeej tsis muaj nqi siab dua 1.6 watts ib kilogram.Txhawm rau muab piv txwv rau koj, ib qho ntawm lub mloog pob ntseg wireless tiag tiag, Apple AirPods, muaj tus nqi SAR ntawm 0.466 watts ib kilogram, uas yog nyob rau hauv qhov txwv tau teev tseg los ntawm FCC.
Kev ceev faj thaum siv wireless TWS earbuds:
-Nov yog ob peb yam uas koj tuaj yeem ua kom txo tau qhov kev pheej hmoo thaum siv pob ntseg:
-Tsis txhob siv lub mloog pob ntseg wireless rau lub sijhawm ntev.
-Txo koj lub xov tooj ntawm tes siv thiab muab tso tseg / hom dav hlau thaum tsis siv lossis ntawm hom hais lus kom txo tau EMF hluav taws xob raug.
-Yog tias koj xav tau ob lub wireless Bluetooth headphones, xyuas kom tseeb tias lawv nyob hauv FCC txwv.
-Thaum siv lub mloog pob ntseg wireless, tua Bluetooth thaum nws tsis siv.Tsis txhob cia lawv nyob twj ywm.
Txhawm rau xaus thiab teb cov lus nug - yog Bluetooth muaj kev nyab xeeb lossis tsis yog - ib yam uas yuav tsum nco ntsoov yog vim tias tsis muaj kev tshawb fawb txaus los ua pov thawj tias Bluetooth hluav taws xob tuaj yeem ua rau puas tsuaj rau DNA (thiab ua rau, ua rau muaj teeb meem kev noj qab haus huv. ), ib qho yuav tsum tsis txhob ua qhov muag tsis pom nrog cov khoom siv Bluetooth txhua lub sijhawm.Nyob rau tib lub sijhawm, lawv yuav tsum tsis txhob txhawj xeeb siv cov cuab yeej no kom txog thaum nws raug kuaj xyuas.Nyob rau niaj hnub no, nws tsis yog tag nrho rau qee cov neeg tso tseg cov cuab yeej no kiag li.Tsis tas li ntawd, cov neeg tuaj yeem tuaj yeem tsis tso siab rau / siv cov cuab yeej Bluetooth (piv txwv li lub mloog pob ntseg), tuaj yeem sim lub raj cua lub mloog pob ntseg es tsis txhob txo lawv cov hluav taws xob Bluetooth.
Peb tseem tsis tau muaj cov ntaub ntawv meej kom nkag siab txog cov kev pheej hmoo tab sis peb tau los ntev nrog kev tshawb fawb thiab tab tom kawm yam tshiab tas li.Ob peb qhov kev ceev faj tuaj yeem mus ntev hauv kev txo koj cov hluav taws xob raug hluav taws xob los ntawm cov khoom siv wireless yog li nws tseem ceeb uas yuav tsum nco ntsoov thaum siv thev naus laus zis.
Wellypraws li tus kws tshaj lij earbuds wholesaler, yog tias muaj lus nug ntxiv txog tws earbuds, thov koj xav dawb rautiv tauj peb. Ua tsaug!
