Ukulahleka kokuzwa kwemvamisa ephezulu kudala izinkinga ngokuzwa imisindo ephezulu. Kungabuye kuholele ku-. Ukulimala kwezakhiwo ezinjengezinwele endlebeni yakho yangaphakathi kungadala lolu hlobo oluthile lokulahleka kokuzwa.

Imvamisa isilinganiso senani lokudlidliza okwenziwa yigagasi lomzuzwana ngomzuzwana. Isibonelo, umsindo olinganiswa ngo-4,000 Hz udlidliza izikhathi ezingama-4,000 ngomzuzwana. Imvamisa, okuwukuphakama komsindo, yehlukile kumfutho, okuyindlela umsindo ozwakala kakhulu ngayo.

Isibonelo, inothi maphakathi no-C kukhibhodi inemvamisa engaphansi nje kuka-262 Hz. Uma uthepha ukhiye kancane, ungakhipha umsindo onamandla aphansi ongazwakali kangako. Uma ushaya ukhiye kanzima, ungakhiqiza umsindo ozwakala kakhulu enkundleni efanayo.

Noma ngubani angaba nokulahleka kokuzwa okuvama kakhulu, kepha kuya kuvame kakhulu ngeminyaka. Ukuvezwa kwemisindo ephakeme noma imisindo ephakeme kakhulu yizimbangela ezivamile zokulimala kwezindlebe kubantu abasha.

Kule ndatshana, sizobheka izimpawu nezimbangela zokulahleka kwemvamisa ephezulu. Sizokutshela nokuthi ungazithatha kanjani izinyathelo zokuvikela izindlebe zakho.

Izimpawu zokulahlekelwa okuphezulu kokuzwa kwe-pitch

Uma unokulahlekelwa okuphezulu kokuzwa kwe-pitch, ungaba nenkinga yokuzwa imisindo efana nale:

• izinsimbi zomnyango
• ifoni nemishini yokusebenza
• amazwi abesifazane kanye nezingane
• izinyoni nemisindo yezilwane

Ungase futhi ube nenkinga yokubandlulula phakathi kwemisindo ehlukile lapho kunomsindo wangemuva okhona.

Ingabe ingunaphakade?

Ukuzwa ukulahleka kuvame kakhulu e-United States. Cishe bavezwa amazinga ayingozi omsindo emsebenzini. Lapho nje izinto ezisendlebeni yakho yangaphakathi sezonakele, imvamisa akunakwenzeka ukubuyisela emuva ukulahleka kokuzwa.

Ukulimala kokuzwa kungahlukaniswa njengokulahlekelwa kokuzwa kwe-sensorineural, ukulahleka kokuzwa okusebenzayo, noma ukuhlanganiswa kwalokhu okubili.

Ukulahleka kokuzwa kwe-sensorineural luhlobo oluvame kakhulu. Kwenzeka lapho izinzwa zakho zokuzwa noma amaseli ezinwele angaphakathi kwe-cochlea yendlebe yakho yonakele. Ukulahlekelwa kokuzwa kwe-sensorineural kuvame ukuhlala unomphela kepha kungathuthukiswa ngezinsiza zokuzwa noma okufakwa kwe-cochlear.

Ukulahleka kokuzwa okusebenzayo akuvamile kakhulu. Lolu hlobo lokulahlekelwa kwezindlebe lubandakanya ukuvimba noma ukulimala kwendlebe yakho ephakathi noma izakhiwo zendlebe ezingaphandle. Kungabangelwa i-wax eyakhiwe yendlebe noma ithambo lendlebe eliphukile. Kwezinye izimo, lolu hlobo lokulahlekelwa kokuzwa lungaguqulwa.

Uma ulahlekelwe ukuzwa, kufanele uvakashele udokotela ukuthola ukuxilongwa okufanele.

Yini ebangela ukulahleka kokuzwa kwemvamisa ephezulu

Izindlebe zakho zangaphandle zizwakala zibheke emgodini wakho wezindlebe kanye nesigubhu sendlebe. Amathambo amathathu asendlebeni yakho emaphakathi abizwa ngokuthi yi-malleus, incus, kanye ne-stapes athwala ukudlidliza okusuka esigubhini sakho sendlebe kuya kusitho esivuthayo endlebeni yakho yangaphakathi ebizwa ngokuthi i-cochlea.

I-cochlea yakho iqukethe amaseli wezinwele anokuqagela okuncane okufana nezinwele okubizwa nge-stereocilia. Lezi zakhiwo ziguqula ukunyakaza kwemisindo kube yimizwa ye-neural.

Lapho lezi zinwele zilimala, ungahle uzwe ukulahleka kwezindlebe okuphezulu. Unamaseli wezinwele ku-cochlea yakho lapho uzalwa. Ukuzwa umonakalo kungenzeka kungatholakali kuze kube yilapho amaphesenti angama-30 kuya kwangu-50 amangqamuzana ezinwele elimele.

Izici ezilandelayo zingaholela ekulimaleni kwe-stereocilia yakho.

Ukuguga

Ukulahleka kokuzwa okuhlobene nobudala kuvamile kubantu abadala asebekhulile. Cishe umuntu oyedwa kwabathathu oneminyaka ephakathi kuka-65 no-74 unezindlebe. Ithinta isigamu sabantu abadala abaneminyaka engaphezu kwengama-75.

Umonakalo womsindo

Ungathola ukulimala kokuzwa kusuka kumisindo yomsindo ophakeme kakhulu nemisindo ephakeme ngokweqile. Ngokuvamile ukusebenzisa amahedfoni ngezwi elikhulu kungadala ukulahlekelwa unomphela kokuzwa.

Omunye uhlole ubudlelwano phakathi kwezidlali zomculo eziphathwayo nokulahleka kokuzwa ezinganeni. Abaphenyi babheka izingane ezingaphezu kwezingu-3 000 ezineminyaka ephakathi kwengu-9 nengu-11 ubudala. Bathola ukuthi amaphesenti ayi-14 ezingane anezinga elithile lokulahlekelwa imvamisa ephezulu. Izingane ezisebenzisa izidlali zomculo eziphathekayo kanye kanye noma kabili ngesonto zazinamathuba aphindwe kabili okuba nokulahleka kokuzwa ukuthi lezo ezingazisebenzisi nhlobo izidlali zomculo.

Ukutheleleka endlebeni okuphakathi

Izimila

Izicubu ezibizwa ngokuthi i-acoustic neuromas zingacindezela emthanjeni wakho wokuzwa futhi zibangele ukulahleka kwezindlebe namathinki ngakolunye uhlangothi.

Izakhi zofuzo

Ukulahlekelwa kokuzwa kungahle kube ingxenye yofuzo. Uma othile emndenini wakho enokulahlekelwa ukuzwa, nawe uthambekele ekukuthuthukiseni.

Imithi

Imithi engadala ukukhubazeka kokuzwa ngokulimaza indlebe yangaphakathi noma imizwa yezinzwa ibizwa ngokuthi yi-ototoxic. Izidakamizwa ezingezona ukuvuvukala (ama-NSAID), amanye ama-antibiotic, kanye neminye imithi yokwelashwa komdlavuza iphakathi kwemithi engaba yi-ototoxic.

Isifo sikaMeniere

Isifo sikaMeniere sibhekise endlebeni yakho yangaphakathi futhi sidale ukushintshashintsha kokuzwa, i-tinnitus, ne-vertigo. Kubangelwa ukwakheka koketshezi endlebeni engaphakathi okungabangelwa ukutheleleka ngegciwane, ukuphendula komzimba, ukuvinjelwa, noma ukuthambekela kofuzo. Isifo sikaMeniere ngokuvamile sithinta indlebe eyodwa.

Ukulahleka kokuzwa kwemvamisa ephezulu eceleni kwe-tinnitus

Ukuvimbela ukulahlekelwa kwemvamisa ephezulu

Ungathatha izinyathelo ukuvimbela ukulahleka kwezindlebe eziphakeme ngokugwema imisindo enephimbo eliphakeme noma imvamisa. Ngisho nokuchayeka kanye emisindweni ephezulu ngaphezu kwama-decibel angama-85 kungadala ukulahlekelwa kokuzwa okungalungiseki.

Nazi ezinye izindlela zokuvikela ukuzwa kwakho.

• Nciphisa ukuvezwa kwakho emisindweni ephezulu.
• Sebenzisa ama-earplugs noma ama-earmuffs lapho uvezwa emisindweni enkulu.
• Gcina ivolumu yakho ye-earbud nehedfoni ohlangothini oluphansi.
• Thatha amakhefu kude ne-TV noma umsakazo.
• Thola izivivinyo zokuzwa njalo ukuze ubambe izinkinga zokuzwa kusenesikhathi.

Ukubonana nodokotela nini

Ububanzi bakho bokuzwa buyancipha njengoba ukhula. Izingane zivame ukuzwa imisindo umuntu omdala ojwayelekile angazinaki. Kodwa-ke, uma ubona ukulahleka okungazelelwe noma ushintsho ezindlebeni zakho, kuwumqondo omuhle ukuthi ukuzwa kwakho kuhlolwe ngokushesha.

Ukulahleka kokuzwa kwezinzwa okungazelelwe okwenzeka ngokujwayelekile endlebeni eyodwa nje kwaziwa njengokungezwa okungazelelwe kokuzwa. Uma uhlangabezana nalokhu kufanele ubone udokotela ngokushesha.

Luyini uhla lokuzwa komuntu?

Abantu bangayizwa imisindo ebangeni lokuvama eliphakathi cishe. Izingane zingakwazi ukuzwa amaza ngaphezu kwaleli banga. Kubantu abaningi abadala, umkhawulo webanga eliphezulu lokuzwa uzungeze i-15,000 kuye ku-17,000 Hz.

Ukubheka, ezinye izinhlobo zamalulwane zingezwa imisindo ephakeme njengama-200,000 Hz, noma cishe izikhathi eziphindwe kalishumi kunomkhawulo womuntu.

Ukudla okudlela endlini

Ezimweni eziningi, ukulahleka kwemvamisa ephezulu akunakuphikwa. Ngokuvamile kubangelwa inqubo yokuguga yemvelo noma kusuka ekuchayekeni emisindweni ephezulu.

Ungawanciphisa amathuba akho okuthuthukisa ukulahlekelwa kokuzwa kwemvamisa ephezulu ngokudayela ivolumu uma usebenzisa ama-headphone, usebenzisa ama-earplugs lapho uvezwa yimisindo ephezulu, futhi uphila impilo ephelele.
