Yendalo
"Ukwamkela" kuzo zonke iindalo ezivakalayo zehlabathi zinikezelwa ngamalungu amathathu kwilungu lokuphulaphula: intloko yangaphakathi, ephakathi nephakathi. Iyokuqala, equlethwe ngumbonakaliso we-auricle kunye wangaphandle, uthabatha ukutshukunyiswa kwomoya kwaye uyiglulisele kwi-eardrum (leyo eyahlula "ukudumala" kwama-molecule!). Iyakhulisa isandi, siyiqondise kwindlebe ephakathi, apho amathambo amancinci emzimbeni atholakala khona: i-hammer, i-anvil kunye ne-stapes (imisipha edibanisa nayo ibangela into efana ne-tampon eyanciphisa ubunzima bokudanduluka kwezandi). Icandelo elibalulekileyo kwindlebe ephakathi yile tube yophicotho (eustachian), eyenza sikwazi ukulinganisela uxinzelelo lomoya kwi tympanum nexinzelelo lwangaphakathi. Ihlala ikhutshwe kuyo i-wax (i-earwax) inezakhiwo ezichasayo, ukukhusela indlebe kwiibhaktheriya ezinobungozi kunye nezinambuzane. Kwindlebe yangaphakathi yinxalenye ebaluleke kakhulu kwinkqubo yokuphicotha - inxalenye yeCorti (yokuvuthwa), efihliweyo kwikhonkco eyenziwe nge-shell egcwele i-fluid (perilymph) kwaye igqitywe ngezakhiwo ezinomsoco (steroids). Ilungiselela ukuguqulwa kwesignali efunyenwe ngaphandle ngaphandle kwentsholongwane yesibindi, ebonwe yingqondo. "I-Culprit" inokuthi ibe yi-banal sulfuric coork, kunye ne-otitis. Uhlobo lwesibini lwesithulu luhlala lubandakanywa neengxaki zemizimba, ukusetyenziswa kwezidakamizwa ze-phototoxic (ezinye iindidi ze-antibiotics), iziphumo zezifo ezithathelwanayo, ukulimala kwentloko kunye neenguqu ezinxulumene neminyaka. Nangona kunjalo, akufanele siphumelele impembelelo eninzi yomsindo, oqhelekileyo kumaxesha anamhlanje. Imvelaphi yokugquma kwemigwaqo yeedolophu ezinkulu, inzondelelo yama-discotheques, iifowuni zee-mobile kunye nabadlali be-MP3 zikhokelela ekuthatheni abahlala phantsi; ayilona liqela elona maninzi kwiinkalo zobunzima bokuphulaphula. Oogqirha bathi - namhlanje umntu uva kakhulu kunabo okhokho iminyaka emininzi edlulileyo: sele sele uneminyaka engama-40 abantu abaninzi beedolophu abakwazi ukwenza i-whisper emgama wamitha amathathu!
Musa ukumemeza kumyeni wakho
Amakhono ophicotho-zincwadi ahlukeneyo kubantu namabhinqa. Umgangatho oqinileyo uva ngakumbi (ngakumbi ingxoxo kwiitoni eziphakamileyo), kodwa uyaqonda ngokucacileyo isiqulatho sesandi kunye nomgama kumthombo wayo. Ladies baqonda ngokugqithiseleyo ukuphakama kwamanzi kunye nokubamba imisindo emnandi (sele isiswini esisodwa, ukuqonda, ngomoya wokuba unxibelelwano), ube neendlebe zomculo ophuculweyo. Ukubethelela ingoma elula kwindawo yokuhlambela, ibhinqa likhohliswa ngokuphindaphindiweyo kathathu!
Ikhuseleko imithetho
Ukugcina "ukuvakala" kumdala kakhulu, oogqirha bacebisa: Ukunciphisa i-headphones (kwaye ukuba ungazibekezelele - khetha i-large, ayiyi-earbuds, enobudlova kwi-nervitive auditory). Nciphisa ixesha lokunxibelelana kwifowuni, jonga ukubukela kwe-TV (ngokukodwa kwi-volume epheleleyo). Lungisa umthwalo ozwakalayo: ukuba emva kokuhlala kwikontoni ye-rock ezindlebeni kwiindandatho ezinde ixesha elide - iinwele zeenwele ze-cochlea zonakaliswe (amandla okududuza awaphule, kwaye awona amasha akhula!). Ukuthintela ingress yamagumbi angaphandle kunye namanzi kwi-canal endle (usebenzisa i-earplugs ezikhethekileyo xa udiza), ukunciphisa ukusebenzisa i-cotton buds (banokutshiza i-sulphur deep in the earal ear), ugweme izifo ze-catarrhal (ezinokuba nzima ukuba zithinteke kwi-otitis media). Emva kwekhefu, sebenzisa isomisi seenwele - isilungiso kunye nesimo esingumanzi sikhupha ukuvuvukala. Ukuqaphela ukwehla kwintetho, kha wuleza ugqirha: kuphela unokufumanisa izizathu kwaye unikwe unyango.
Qaphela, bantwana!
Kubalulekile ukuxilonga ukukhubazeka kweendlebe ngexesha - banokunciphisa intuthuko yengqondo yomntwana kwaye banciphise ukuphuhliswa kwentetho. Ukuba kwinyanga enye umntwana akayi kuvutha kwizandi ezivakalayo, ngomnyaka wesigxina - akayi kuhlaziya, ngonyaka - akayi kuthetha amagama okuqala, kubalulekile ukuvakala i-alamu. Ingaba uhlolo "luqala" ngokulandelelana? Qaphela imeko yomsindo - abantwana banomdla kakhulu kwimiphumo yalo (kubonakalisa ama-receiver sensory atholakala entendeni yangaphakathi, kwaye ukulahlekelwa kwindlebe kwenzeka ngokungaqondakaliyo kwaye ayinakuphikiswa). Imvelaphi yesandi esivumelekileyo yomntu ukusuka kwi-45 ukuya kwi-50 decibels (ehambelana nengxoxo ecebileyo). Ngezwi elikhulu lama-pulse lihamba ngokukhawuleza, i-90 - tachycardia iqala. Kwizandi zowamaxesha amaninzi umzimba uphendule ngokucacileyo, kodwa uvuselela ukuvakalelwa kwengxaki engaqondakaliyo. Ingxolo eyingozi: umzila (85), umdlali ngokuphakamisa umsindo (110), amathoyizi aphezulu omculo (125), izixhobo zomlilo kunye nezixhobo zokucima umlilo (135), ukubola (140).
Ipale yezandi
Ubukho beendlebe zomculo kuxhomekeke ngqo kulwimi olukhulunywe ngumntu. Ngokomzekelo, amaKorea abo ulwimi lwabo luhluke ngokungafani (ukuhluka kwendlela yokubiza igama elifanayo kungatshintsha intsingiselo yalo), ngokuqinisekileyo yonke into ingumculo ukusuka ekuzalweni. Ezinye iitalente ziyakwazi ukubona umsindo wembala kunye nombala wezandi.
