Kutshanje, kuye kwakho ukwanda kokulahleka kwabantu bokuva ngaphezulu kweminyaka ye-60. Indoda endala ekhaya sele ithethile kakhulu, kulula ukuyilwa, kwaye iphinde ibe nomsindo? Ukuba intsebenzo enjalo ithathelwa ingqalelo kakhulu, kunokuba oko kuthetha ukuba ukuva kwabantu abadala kuyancipha.

Ngomhla ka-Matshi 3rd, "usuku lwendlebe yothando" lukwayindawo yemihla ngemihla yothando. Masithethe ngokulahleka kwendlebe okuhambelana nobudala kunye nokuguga kwezitho. Benza ntoni abantu abalupheleyo xa bengavumi ukusebenzisa izixhobo zokuva?

Ngokwemigangatho yelizwe, inqanaba lokulahleka kwendlebe lahlulwe ngokwezigaba ezithandathu ezilandelayo.

1. Ukuva okuqhelekileyo: ngaphantsi kwe25dB (decibel). Kukudidi oluqhelekileyo lokuva.

2. Ukulahleka kwendlebe okuthambileyo: 25 ukuya kwi-40 dB. Isigulana asisiva okanye siphulukana nokuva nje okuncinci kwaye ngokubanzi asichaphazeli ubuchule bokuthetha ngomlomo.

3. Ukulahleka kokuva okuphakathi: I-41 ukuya kwi-55 dB. Kwindawo ekumgama omncinci, ingxolo yangemuva, kunye nengxoxo edibeneyo, uya kufumanisa ukuba awukwazi ukuva ngokucacileyo; umthamo weTV uphakame kakhulu; kwenzeka into evelayo, kwaye isindululo sendlebe siqala ukwehla.

4. Ukumodareyitha ukuya ekulahlekelweni kokuva okunzima: I-56 ukuya kwi-70 dB. Ukuva iincoko ezinkulu kunye nezandi zemoto.

5. Ukulahleka kakhulu kwendlebe: I-71 ukuya kwi-90 dB. Izigulana zinokuva amazwi amakhulu okanye iincoko ezikudidi olusondeleyo zize ziyiqonde ingxolo eqhubayo okanye iikhamisa, kodwa ingeyiyo i-consonants.

6. Ukulahleka kakhulu kokuva: okukhulu kune-90dB. Izigulana azikwazi ukuthembela kwindlebe kuphela ekunxibelelaneni nabanye, kwaye bafuna ukufundwa kwemilebe kunye noncedo lolwimi lomzimba.

Abantu abadala abanengxaki yokuva banokucinga okungendawo kunye nememori kunaleyo babeva ngokuqhelekileyo. Ukuva ilahleko, ukukhuthaza kwengqondo yesandi kuncitshisiwe, kwaye kuthatha amandla amaninzi ukuqhubekisa isandi, ngaloo ndlela sinikezela ngamanye amandla asetyenzisiweyo ukujongana nememori nokucinga. Ethubeni, amandla okucinga kunye neenkumbulo zabantu abasele bekhulile ziya kuncipha. Ebomini, abantu abadala baya kuba nobunzima kunxibelelwano, banciphise unxibelelwano, njl, de baphulukane nomdla wabo wentlalontle, ngokuthe ngcembe bazihlukanise nomhlaba wangaphandle, babe zizidenge kwaye babe phantsi.

Ke ngoko, xa ukufunyanwa kokulahleka kwabadala kufunyenwe, usapho kufuneka luthathe abantu abadala baluse esibhedlele ukuze lufumane i-otolaryngology, intloko nentamo utyando ngexesha (inkqubo yonyango eqhelekileyo, uvavanyo lwendlebe, kunye novavanyo oluvavayo lwethoni yokumamela) ukufumanisa unobangela. ilahleko yokuva.
