WEBVTT 00:00.560 --> 00:07.360 Namhlanje, ungababona phantse kuyo yonke indawo ezindlebeni zabantu emsebenzini, xa behamba nangexesha lomthambo. 00:07.360 --> 00:15.019 Sithetha nge-headphones zeBluetooth ezingenazingcingo ezifana nee-headphones ezifakwayo ezithandwayo, ii-"AirPods" ze-Apple. 00:15.019 --> 00:22.118 Umgangatho weBluetooth ongenantambo wenza ukuba idatha, umculo, iividiyo okanye imifanekiso zidluliselwe 00:22.118 --> 00:26.489 kumgama omfutshane, usebenza ngendlela efanayo neWi-Fi. 00:26.489 --> 00:31.797 Ngokuvelisa inkangu ye-electromagnetic enomtsi ophezulu, itekhnoloji yenza ukuba imodeli 00:31.797 --> 00:35.303 yesidluliseli nemodeli yesamkeli zidityaniswe. 00:35.303 --> 00:41.015 Umgama ophezulu wokusebenza wahluka phakathi kweemitha ezili-10 nezili-100, kuxhomekeke kwisixhobo. 00:41.015 --> 00:46.563 Ishishini lee-headphone ezifakwa endlebeni liyachuma kwaye itekhnoloji yazo isetyenziswa kakhulu. 00:46.563 --> 00:51.783 Oku kuyayityeshela umbuzo wokuba ukukhanya okunobungozi okunzulu kangaka endlebeni – kanye ecaleni 00:51.783 --> 00:56.893 kwengqondo – kunegalelo elithini emzimbeni womntu. 00:56.893 --> 01:05.416 Kwisibheno kwi-WHO nakwiZizwe eziManyeneyo esapapashwa ngo-2019, izazinzulu ezingama-250 ezivela kumazwe angaphezu kwama-40 01:05.416 --> 01:14.626 zalumkisa ngeengozi ezinzulu zempilo ezibangelwa ziihedfoni ezifana nee-Apple AirPods nezinye iitekhnoloji ezingenantambo. 01:14.626 --> 01:21.446 Kukho ubungqina besayensi obukhulayo ngokukhawuleza obubonisa ukuba imimandla ye-electromagnetic eveliswa zizixhobo 01:21.446 --> 01:27.495 ezingenazingcingo neze-elektroniki ezifana neefowuni eziphathwayo, iimasti zefowuni, i-Wi-Fi, izixhobo 01:27.495 --> 01:35.676 zokubeka iliso kumntwana kunye nee-headphone zeBluetooth ziyingozi kubantu, kwizityalo, kwizilwanyana nakwintsholongwane. 01:35.676 --> 01:43.673 Iziphumo ezibi kwimpilo yamabala ombane-magnethi ziquka: umngcipheko onyukileyo womhlaza, uxinzelelo lweeseli, umonakalo 01:43.673 --> 01:51.003 kwizifo zofuzo, utshintsho olusemalungiselelweni nasekusebenzeni kwenkqubo yokuzala, ukuphazamiseka ekufundeni 01:51.003 --> 01:58.799 nakwinkumbulo, iziphazamiso zenkqubo yomthwalo-mqondweni, kunye ne- iziphumo ezibi kwimpilo-ntle. 01:58.799 --> 02:08.458 Isibheno samazwe ngamazwe siqhubeka sisithi: "Iigunya ezininzi ezinoxanduva lokubeka imida zisilele kumsebenzi wazo wokumisela 02:08.458 --> 02:14.820 izikhokelo ezifanelekileyo zokukhusela uluntu, ingakumbi abantwana, abasesichengeni 02:14.820 --> 02:19.098 ngakumbi kwiziphumo zamasimi ombane-magnethi." 02:19.098 --> 02:26.515 Olu buno, bokuba itekhnoloji yeBluetooth ayifumani ngqwalasela yaneleyo, ingakumbi kwizinto zokudlala zabantwana, 02:26.515 --> 02:30.961 luxelwe ngumama okhathazekileyo oqhagamshelane neKla.TV. 02:30.961 --> 02:35.877 Unyana wakhe oneminyaka emi-5 ubudala uye wavuka ngequbuliso iingcambu zakhe zomthwalo entanyeni. 02:35.877 --> 02:42.455 Oku kwenza usapho lwacinga ukulinganisa ixabiso le-radiation 'lepeni' ethandwayo yonyana wabo, i-"BOOKii pen" – 02:42.455 --> 02:49.593 ipeni yedijithali eshukumisa ilizwi enokuthi, umzekelo, yenze umfanekiso okwincwadi yabantwana uthethe. 02:49.593 --> 02:56.397 Yakhupha umqondiso oqhubekayo kumlinganiselo wama-200,000 ukuya kuma-300,000 microwatts. Uphando 02:56.397 --> 03:04.848 kwi-intanethi lubonise ukuba, ngokutsho komvelisi, akunakwenzeka ukucima umsebenzi weBluetooth yepeni. 03:04.848 --> 03:12.769 Ngenxa yamava akhe, lo mama okhathazekileyo wamangaliswa kukuba umenzi akazange anyanzelwe ukuba azise abazali ukuba 03:12.769 --> 03:21.393 ukusetyenziswa kwepeni ye-BOOKii kubeka abantwana babo kuloo mitha kunye neengozi zempilo ezihambelana nayo. 03:21.393 --> 03:27.643 Isazi ngengqondo esidumileyo uNjingalwazi Andrew Huberman waseStanford University School of Medicine 03:27.643 --> 03:35.130 ubonakalisile ukuba ayizozana abantwana kuphela kodwa nabantu abadala bayachaphazeleka kubuchwepheshe beBluetooth. 03:35.130 --> 03:44.136 Uphande ngokunzulu ngokusetyenziswa kwee-headphone zeBluetooth kwaye ukwabuleka ngeengozi zempilo ezinokubakho. 03:44.136 --> 03:49.345 Wayeneengcambu ze-lymph ezidumbileyo ngasemva kweendlebe zakhe kunye nokushisa okukhawulezileyo komzimba, 03:49.345 --> 03:53.222 into awayeyibeka kusetyenziso lwee-headphone zeBluetooth. 03:53.222 --> 03:58.839 Yiloo nto watshintshela kwi-headphone enocingo. 03:58.839 --> 04:02.773 NgokukaHuberman, "ubushushu nezihlunu zemithambo-luvo abangabahlobo." 04:02.773 --> 04:11.996 Ngesi sizathu, unexhala ngeengozi ezinokubakho ezinokuvela xa iindawo ezibuthathaka kangaka zibekwa kubushushu obungapheliyo. 04:11.996 --> 04:20.066 Abavelisi, abathengisi kunye namagunya olawulo ezixhobo zesandi ezingenazingcingo bayazityeshela izilumkiso. 04:20.066 --> 04:23.218 Ingaba oku kunokuba kungenxa yezinto eziphathelele koqoqosho? 04:23.218 --> 04:31.089 Imakethi yezixhobo zesandi ezingenazingcingo iqikelelwe kwiidola ezizibhiliyoni ezingama-64.76 ngo-2024, kwaye 04:31.089 --> 04:39.635 ukukhula kwihlabathi jikelele kulindeleke ukuba kufikelele kwiidola ezizibhiliyoni ezingama-206.84 ngo-2032. 04:39.635 --> 04:45.862 UJames Russell uqaqambisa ezinye iingxabano zomdla phakathi kweshishini leefowuni eziphathwayo kunye nophando kwicandelo 04:45.862 --> 04:49.749 lobuchwepheshe kanomathotholo kwifilimu yakhe yobungqina. 04:49.749 --> 04:55.096 Le filimu inika ilizwi kwiingcali zenzululwazi ezahlukeneyo, kubameli bamashishini, nakugqirha. 04:55.096 --> 05:01.206 Phakathi kwezinye izinto, ikhankanya ukuba ngokuqinisekileyo kukho ungquzulwano lwezinto ezuncedo ngokumalunga 05:01.206 --> 05:05.490 nokuxhaswa ngemali kwezifundo kwishishini likamaradio. 05:05.490 --> 05:11.689 Xa kuqwalaselwa isifundo, ngoko ke kufanelekile ukuthathela ingqalelo ukuba ngubani owasixhasayo ngemali. 05:11.689 --> 05:19.227 Imigangatho yerediyo kuluhlu lwe-high-frequency iyinxalenye yobomi bethu bemihla ngemihla, kwaye kuyothusa ukuba 05:19.227 --> 05:26.916 okwangoku akukho zalathiso zamazwe ngamazwe kwaphela ezinxulumene nomonakalo wezempilo oqhubekayo okanye umhlaza. 05:26.916 --> 05:31.649 Ezi zikhokelo zisekelwe kuphela kwiziphumo zokushisa okanye kwiziphumo ezikhawulezileyo ezifana 05:31.649 --> 05:34.857 nokurhawuzelela kolusu okanye ukudumba kwamaqhina. 05:34.857 --> 05:39.223 Akukabikho mgangatho usisiseko osamiselweyo wokumisela iingozi zempilo zexesha elide. 05:39.223 --> 05:46.692 Oku kuthetha ukuba ngokungenakuphepheka akukho njongo kwishishini okanye kwiingcali zenzululwazi elizithengileyo 05:46.692 --> 05:52.442 yokukhusela uluntu kumonakalo wezempilo wexesha elide. 05:52.442 --> 05:57.102 Wonke umntu unokunceda ukukhusela okusingqongileyo kwimingcipheko yezempilo: 05:57.102 --> 06:03.243 Ngokunika ulwazi olupheleleyo malunga neengozi ezibangelwa yitekhnoloji yeBluetooth neyeefowuni 06:03.243 --> 06:08.649 eziphathwayo, nangokungazisebenzisi apho kunokwenzeka khona. 06:08.649 --> 06:11.256 Hlala unolwazi – phinda ungene kwakhona ngomso.
