Ngisho nososayensi sebevele bahlaba umkhosi - ebudaleni abantu abayizigidi eziyizinkulungwane eziyi-1 bazoba izithulu
Kuyacaca ukuthi abazali bavame ukwenza ihaba lapho betshela izingane zabo ngezinkinga zempilo ezingase zibe khona ngenxa yokusebenzisa izinto zobuchwepheshe. Kodwa ubungozi bokulahlekelwa ukuzwa ngenxa yomculo onomsindo abukho kude nephupho. Bheka nje abantu abangaphezu kuka-40 abasebenza emafemini noma ezinkundleni zezindiza. Emazingeni omsindo angaphezu kuka-100 dB, ukuzwa akuzwakali. Ngisho nokweqisa okukodwa kuthinta izitho zokuzwa. Futhi kwenzekani ngezigubhu zendlebe lapho zinikezwa umsindo omkhulu nsuku zonke?
Inqubomgomo "yokulalela ngokuphephile" yinto entsha emhlabeni wamagajethi
I-WHO (World Health Organization) ilinganisela ukuthi cishe abantu abayizigidi ezingu-400 abaneminyaka engaphezu kuka-40 emhlabeni wonke kakade banezinkinga zokuzwa. Ucwaningo luye lwabonisa ukuthi ama-headphones ajwayelekile abe umthombo wokukhubazeka. Kutholwe ukuthi ngevolumu ephakathi, ama-headphone avaliwe nama-earbud akhipha i-102-108 dB. Ngevolumu ephezulu - 112 dB nangaphezulu. Imvamisa kubantu abadala ivolumu ifinyelela ku-80 dB, ezinganeni - kufika ku-75 dB.
Sekukonke, ososayensi benza izifundo ezingama-35 emazweni ahlukahlukene omhlaba. Bebehanjelwe abantu abangu-20 000 abaneminyaka engu-12 kuya ku-35. Ngaphezu kokulalela umculo ngama-headphone, "iziguli" zivakashele izindawo zokuzijabulisa lapho umculo ubudlalwa phezulu. Ikakhulukazi, amakilabhu okudansa. Bonke abahlanganyeli, ngamunye ngendlela yakhe, bathole ukulimala kokuzwa.
Ngokusekelwe ocwaningweni, ososayensi baye ku-WHO ngezincomo zokwethula inqubomgomo "yokulalela okuphephile". Kubandakanya ukukhawulela amandla ama-headphone. Ngokwemvelo, lokhu kuhloswe kakhulu ezidingweni zabakhiqizi.
Ngokusho kochwepheshe abasebenza emkhakheni wezobuchwepheshe be-IT, isikhalazo esinjalo cishe ngeke sithole ukwesekwa phakathi kweziphathimandla noma abakhiqizi. Phela, kuthinta izintshisekelo zezezimali ezimbalwa ngesikhathi esisodwa:
- Ukuncipha kokukhanga komkhiqizo ngenxa yamandla alinganiselwe.
- Izindleko zokuhlela amalabhorethri ukuze kuqinisekiswe izici ezimenyezelwe zama-headphone.
- Ukulahlekelwa imali engenayo yezikhungo zezokwelapha (odokotela nabakhiqizi bezinsiza zokuzwa).
Kuvela ukuthi "ukusindiswa kwabacwilayo kuwumsebenzi wokucwila ngokwabo." Okusho ukuthi, umuntu ngamunye kufanele aqonde umphumela wesimo samanje. Futhi uthathe isinyathelo ngokwakho. Kodwa mancane amathuba okuthi intsha ilalele umculo ngevolumu ephansi. Futhi iseluleko sabazali sesivele sesikhulile, lapho lezi zinkinga sezivele sezivele. Ngakho-ke sifika emthonjeni wehaba lezinkinga zabazali abazama ukubonisana nezingane zabo.
