Mayelana nalolu hlelo lokusebenza

Uhlelo lokusebenza luhlinzeka (1) ukuhlolwa kokuhlola okuphezulu kokuxazulula kwamafrikhwithi angama-56 ebangeni eliphakathi kwama-55-7,040 Hz okungenziwa kwimvelo yasekhaya yabasebenzisi; kanye (2) nezikhathi zokuqeqeshwa ezikhethekile zokulahleka kokuzwa ezihlelwe ngandlela-thile ezisiza ukuthuthukisa ukubalwa kwezimpawu zokuqonda nokuqonda ukukhuluma (izilimi ezisekelwayo: isiNgisi, isiFulentshi, isiJalimane, iSpanishi).

Izilingo Ezingashadile
«Izilingo Ezingashintshiwe» zisetshenziselwa ukunquma umkhawulo wokuzwa kwabasebenzisi wefrikhwensi enikeziwe (ithoni) yendawo eyodwa yangakwesobunxele, indlebe yangakwesokunene, noma zombili izindlebe ndawonye. Ukuhlolwa okukodwa kwenziwa ngokuletha ithoni yemvamisa ekhethiwe kaninginingi ngenkathi kulungiswa ngempumelelo ukuqina (ukuphakama). Indlela ejwayelekile iqala ngomsindo wokuqala ochazwe umsebenzisi (isb., -25.5db) futhi inciphisa umsindo ngezinyathelo ze -1.1.db kuze kube yilapho umsebenzisi engakwazi ukuthola noma yimuphi umsindo.

Ukuhlolwa Okugcwele
«Ukuhlolwa Okugcwele» kusetshenziselwa ukunquma umkhawulo wokuzwa kwabasebenzisi wamamayela angama-56 ebangeni eliphakathi kwama-55-7,040 Hz (ama-octave angu-7; amathoni ayi-8 nge-octave), aqala ngendlebe yangakwesobunxele futhi, lapho eseqedile, aqhubeke ngendlebe yangakwesokudla. Kumvamisa ngamunye, ubukhulu (ukumemeza) kukhuphuka ngokulandelana ezitebhisini ze- + 1.5db (kuqala ngenani elichazwe umsebenzisi) kuze umsebenzisi avume ukubonwa kwezwi. Umphumela uboniswa ngendlela yamashadi we-bar "ukulahleka kokuzwa njengomsebenzi wemvamisa".

Ukuqeqeshwa 1: Ukusebenza emikhondweni yezincwadi ezinamaphepha
«Training1» isula ngokusebenzisa amaza angama-56 phakathi kwama-55-7,040 Hz (ama-octave ayi-7; amathoni ayi-8 nge-octave); ubude bethoni yimizuzwana engu-8 ngokuqina okuchaziwe kwangaphambili (ukukhala okukhulu) nezindlebe (noma) ezikhethiwe. Uyacelwa ukuthi uqaphele ukuthi noma yikuphi ukuqeqeshwa okubhaliwe kuzokhombisa umphumela ofiselekayo kuphela uma izikhathi zokuqeqesha ziphindwa kaningi (isb., Kabili ngosuku imizuzu engu-15).

Ukuqeqeshwa 2: Ukusebenza ukuze ukwazi ukukhuluma
«Ukuqeqeshwa 2» kuveza umbhalo ojwayelekile wesikhathi semizuzwana engama-60 ngasikhathi esichaziwe (ubukhulu) kanye nezindlebe ezikhethiwe. Ukugxila kugxilwe ekuqondeni amandla enkulumo: abasebenzisi baqala ngamandla amakhulu futhi bagxile ekuqondeni igama ngalinye. Kamuva, abasebenzisi banganciphisa ukuqina futhi baphinde ukuqeqeshwa kabili ngosuku imizuzu engu-15, babheke isikhathi sokuqeqesha namandla asetshenzisiwe. Izilimi zingamaNgisi, isiFulentshi, isiJalimane neSpanishi.

Isizinda Sesayensi
Ukulahleka kokuzwa: Ukulahleka kokuzwa kuyisimo sempilo esivamile kubantu abadala asebekhulile abane-50% yabantu abaneminyaka engama-60 noma ngaphezulu. Kwenza abagulayo banciphise amandla okuxhumana kahle nomndeni, iqembu lontanga, nendawo yokusebenza. Kuholela ekucindezelekeni okungapheli futhi kuhlotshaniswa nokuqina kokuqina kwengqondo nokwelashwa, njengokuhlukaniswa komphakathi, ukwehla kwengqondo, kanye nokudangala.

I-Etiology: Ukulahleka kokuzwa kuyisimo esiyinkimbinkimbi, esibonisa ukuhlukahluka kwezempilo lapho kuthinteka khona izici eziningi zofuzo nezemvelo. Izici zezemvelo zibandakanya ukuvezwa komsindo, ukuvezwa kwe-ototoxin, izifo, ukubhema kanye nama-comorbidities afana ne-hypertension noma isifo sikashukela. Kunokwehluka okuhlukile phakathi kwesifundo ngokuya ngokuqala, i-pathology, kanye nendlela yokonakala. Okubaluleke kakhulu ukuze ukwazi ukukhuluma kahle imvamisa ethintekayo ebangeni eliphakathi kwama-55-7,040 Hz (ama-octave ayi-7).

Izinsizakuzwa: Iziguli zivame ukubika impilo ephuculiwe ngokusebenzisa izinsiza zokuzwa kepha zivame ukukhala ngokuthi azikuqondi ukukhuluma, ikakhulukazi lapho kukhona umsindo wasemuva. Yize kusetshenziswe amasu wokwehlisa umsindo nama-microphone aqondile, ukuxhumana kwansuku zonke ngezinsizakalo zokuzwa namanje kusabeka imingcele ekhathazayo njengamanje.

Ongakwenza ngakho: Kwabadala abalahlekelwe izindlebe, ukuqeqeshwa okuqondile kwamazwibela kungenza ukuxhumana kwezimo ezinomsindo ngoba cishe njalo kuthuthukisa ukuzwela ukukhuluma. Ngaphezu kwalokho, ukuqeqeshwa kwamacontent ejwayelekile kwenza imisebenzi engasebenzi futhi kwehle ngokwengqondo kakhulu - ukubamba iqhaza nokwenza okuthile ngakho kuyisinyathelo esibaluleke kakhulu sokubhekana ngokuphumelelayo nokulalelwa kwezindlebe.
