Nangona izazinzulu sele zikhalisa i-alamu - ebudaleni abantu be-1 billion baya kuba zizithulu
Kucacile ukuba abazali badla ngokubaxa izinto xa bexelela abantwana babo ngeengxaki zempilo ezinokwenzeka ngenxa yokusetyenziswa kwezixhobo zombane. Kodwa umngcipheko wokungeva ngenxa yomculo ongxolayo awukude nentelekelelo. Jonga nje abantu abangaphezu kwama-40 abasebenza kwiifektri okanye kumabala eenqwelomoya. Kumanqanaba esandi angaphezulu kwe-100 dB, ukungeva akwenzeki. Kwanokugqithisa nje okukodwa kuchaphazela amalungu okuva. Yaye kwenzeka ntoni kumagubu endlebe xa eva isandi esikhulu yonke imihla?
Umgaqo-nkqubo "wokuphulaphula ngokukhuselekileyo" yinto entsha kwihlabathi lezixhobo
I-WHO (World Health Organization) iqikelela ukuba malunga nama-400 ezigidi zabantu abangaphezu kweminyaka engama-40 ehlabathini lonke sele benengxaki yokuva. Uphononongo lubonise ukuba ii-headphones eziqhelekileyo zaba ngumthombo wokukhubazeka. Kwafunyaniswa ukuba kwivolumu ephakathi, i-headphones evaliweyo kunye nee-earbuds zikhupha i-102-108 dB. Ngomthamo omkhulu - 112 dB nangaphezulu. Isiqhelo kubantu abadala ngumthamo ukuya kwi-80 dB, kubantwana - ukuya kuma-75 dB.
Lilonke, izazinzulu zenze izifundo ezingama-35 kumazwe ahlukeneyo ehlabathi. Bazinyaswe ngabantu abangama-20 abaneminyaka eli-000 ukuya kuma-12 ubudala. Ukongeza ekuphulaphuleni umculo kwii-headphones, "izigulane" zatyelela iindawo zokuzonwabisa apho umculo wawudlalwa ngokuvakalayo. Ngokukodwa, iiklabhu zomdaniso. Bonke abathathi-nxaxheba, ngamnye ngendlela yakhe, bafumana amanxeba okuva.
Ngokusekelwe kuphando, izazinzulu zaya kwi-WHO ngengcebiso yokwazisa umgaqo-nkqubo "wokuphulaphula ngokukhuselekileyo". Ibandakanya ukunciphisa amandla ee-headphones. Ngokwemvelo, oku kujoliswe ngakumbi kwiimfuno zabavelisi.
Ngokutsho kweengcali ezisebenza kwintsimi ye-IT teknoloji, isibheno esinjalo asinakwenzeka ukufumana inkxaso phakathi kwabasemagunyeni okanye abavelisi. Emva kwayo yonke loo nto, ichaphazela umdla wemali oliqela ngaxeshanye:
- Ukunciphisa umtsalane wemveliso ngenxa yamandla angaphantsi.
- Iindleko zokuququzelela iilebhu zokuqinisekisa iimpawu ezibhengeziweyo zee-headphones.
- Ilahleko yengeniso yamaziko ezonyango (oogqirha kunye nabavelisi bezixhobo zokuva).
Kuvela ukuba "usindiso lokutshona ngumsebenzi wabo batshona." Oko kukuthi, umntu ngamnye kufuneka aqonde umphumo wemeko yangoku. Kwaye uthathe inyathelo ngokwakho. Kodwa akunakwenzeka ukuba abakwishumi elivisayo baphulaphule umculo ngesandi esiphantsi. Kwaye iingcebiso zabazali sele zikhulile, xa ezi ngxaki sele zivele. Kwaye ke sifika kumthombo wokubaxa iingxaki zabazali abazama ukuqiqa nabantwana babo.
