Iingcaciso zixhomekeke kuBani Ocelayo
Kuthetha ukuthini ukuba sisithulu kwaye njani ukuhlukana nokuba nzima ukuva (HOH)? Impendulo ixhomekeke kubani owubuzayo kwaye yiyiphi imbono okhangele kuyo. Uluntu lwezonyango, ngokomzekelo, lunentsingiselo eqinileyo, kodwa abantu abasemaphandleni okanye kwi-HOH kuluntu banokucinga ngokuthe ngqo.
Inkcazo yezoNyango
NgokweMveli, ukulahlekelwa kwintetho kuchazwe ziziphumo zovavanyo lokuvavanya.
Kukho iiparameters ezibekwe ukubeka umntu njengesisithulu okanye unzima ukuva. Uvavanyo oluvakalayo lokuvavanya luvavanya indlela izandi ezivakalayo kwibala lobubanzi kufuneka zibe yintoni ukuze uzifumane. Kwakhona ulinganisa indlela okwazi ngayo ukuthetha intetho.
Ukuba awukwazi ukufumana izandi ezithembekileyo kunezi-90dB HL (i-Decibels Level Hearing), kuthathwa njengento elahlekileyo yokuvalelwa kweendlebe kwezo zihlandlo. Ukuba umyinge wama-frequency kwi-500Hz, 1000Hz, no-2000Hz ungama-90dB okanye ngaphezulu, umntu uthathwa njengesithulu.
Umntu onzima ukuphulaphula unokufumana uluhlu lokulahlekelwa kwindlebe ukususela kumncinci ukuya kunzima. Kufuneka kuqatshelwe ukuba iteknoloji yokukhulisa ifumaneka kubantu abanokulahlekelwa kwindlebe ephantsi.
Inkcazo yeNkcazo
Inkcazo yenkcubeko ihluke kakhulu kunenkcazo yezokwelapha. Ngokweenkcazo zenkcubeko, isisithulu okanye unzima ukuva akukho nto inokuyenza malunga nokuba ungayiva kangakanani.
Endaweni yoko, kuhambelana nendlela ozichaza ngayo. Ingaba ubalisa ngokuthe ngqo ukuva abantu okanye abantu abazizithulu? Uninzi oluninzi lwezentetho zabantu abanokuziva luzibona njengezizithulu.
Ngamanye amaxesha, lo mmahluko phakathi kwezithulu zentlanga kunye nalabo abanokulahlekelwa kwindlebe enzulu kunokuboniswa ngendlela igama elithi "izithulu" libhaliwe.
Ngokomzekelo, ukuba ubona "abazizithulu" kunye nenkunzi enkulu D , ngokuqhelekileyo ibonisa inkcubeko yesithulu . Ngakolunye uhlangothi "isisithulu" sipelo esincinci d sibonisa ukulahlekelwa kwindlebe kwaye umntu angenakuzijonga njengenxalenye yenkcubeko yezithulu.
Iingcali zengqondo
Kukho nabo abanezonyango kunye nabasebenzi abazizithulu abafuna ukuba, "andisithulu, andinzima ukuva." Le nkcazo isoloko eyenziwa ngabantu abanokulahlekelwa kwindlebe abaphikayo malunga neqondo lokulahlekelwa kweendlebe. Bengahle balungele ukuvuma ubunzima bokulahlekelwa kwintetho.
Ukongezelela, intuthuko kwezobuchwephesha zezimpembelelo ze-cochlear ziphazamisa imigca ngakumbi. Abantu abaninzi abanokulahlekelwa kwindlebe ngoku, banokukwazi ukuthetha ngomlomo baze bathathe inxaxheba njengomntu ovayo.
Ngenxa yezi zizathu, indlela umntu azichazela ngayo ngokwabo ukulahlekelwa kwindlebe kaninzi ngokubhekiselele kwimbono okanye ukhetho kunoma yini enye.
Inkcazo yesiBini
Ingaba abantu abaneemplantshi ezinobungakanani abalahlekelwa yindlebe zancitshiswa zibe ziincinci ezingama-20 dB ezivakalayo zokuva okanye izithulu? Kwimbono yobubhali bombhali, impendulo, "bobabini."
Xa umntu onomfakeko we-cochlear uye wafaka kwaye uyayiva kakuhle, banzima ukuva.
Xa ukufakelwa kuphelile kwaye abanakuva nantoni na, abayizithulu. Kuyafana nokuncediswa kwezixhobo zokuva. Esidlulileyo, umbhali wayeza kuthi "usemoyeni" xa egqoba ukuva uncedo kunye nokusebenza njengomntu onokulahlekelwa kwindlebe, kodwa "ngaphandle emoyeni" xa engagqoki iindlebe zengxoxo kwaye akakwazi ukuva nantoni na.
ILizwi
Njengoko ubona, akukho ncazelo eyingqinileyo esitshela ukuba umntu uyisithulu okanye unzima ukuva. Nangona inkcazo yezokwelapha ingabhekisela kuwo wonke umntu, ukuqonda komntu ngamnye ukulahlekelwa kwindlebe kunye nendlela abafanelwe ngayo (okanye bengenzi) kwisithethe esingasisityebi kubaluleke kakhulu ukuba baqwalasele.
Enyanisweni, akukho mpendulo echanekileyo okanye engalunganga ehambelana nawo wonke umntu. Ngokuqhelekileyo kukubuza ukuba yeyiphi umntu ekhethayo ngaphambi kokuba enze izigqibo.
