Ngokucacileyo ukudlulisela yonke imbono yezemfundo yeyona ntlonipho isisiseko kulwazi

Kwiiholo zezifundo ezinokwamkela amakhulukhulu abantu, iinkqubo zesandi zomthombo wesithethe zihlala zijongana neemeko ezingaqhelekanga: abaphulaphuli abakumqolo ongaphambili baziva bengeva, kodwa abaphulaphuli abakumqolo ongemva bafumana kunzima ukuva kakuhle. Ingxaki yentsimi yesandi esingalinganiyo ichaphazela kakhulu ukusebenza konxibelelwano lwezemfundo, kwaye isithethi somgca womgca kwintsimi ye-audio yobugcisa sesona sisombululo silungileyo sokusombulula le ngxaki.

Isithethi somgca welayini iye yaba yinto ekhethwayo kwiiholo ezinkulu ngenxa yenzuzo yolawulo oluthe nkqo. Ngokubala ngokuchanekileyo ukulungelelaniswa okuthe nkqo kweeyunithi ezininzi, amaza omsindo aqondiswe kwaye aqikelelwe njenge-flash light, egubungela ngokufanelekileyo iindawo ezikude kunokuba asasazeke kuwo onke amacala kunye nokuchitha amandla. Oku kuthetha ukuba nabaphulaphuli abahleli kumqolo ongasemva banokonwabela phantse inqanaba elifanayo loxinzelelo lwesandi kunye nokucaca kwelizwi njengakumqolo ongaphambili, baphumeze ngokwenene ukuvakala kwesandi esikumgangatho ophezulu kuyo yonke indawo.

Ukucaca okugqwesileyo kolwimi yeyona mfuno iphambili yeeholo zemfundo. Isisombululo somgca kwiinkqubo zeaudio zezobugcisa ziphucula kakhulu i-Speech Transmission Index (STIPA) ngokunciphisa izibonakaliso ezinobungozi ukusuka kwiisilingi kunye neendonga, ukuqinisekisa unxibelelwano oluchanekileyo lwexesha ngalinye lobuchwephesha kunye neenkcukacha zedatha, kunye nokuphepha ukuphazamiseka kolwazi lwezemfundo ngexesha lokudluliselwa.

Ubuhle kunye nokuguquguquka kwendawo zibaluleke ngokulinganayo. Inkqubo yesandi yoluhlu lwangoku inokwamkela uyilo lokuphakamisa olufihliweyo, olungagcini nje ngokugcina indawo ecocekileyo kunye nenhle yeholo, kodwa kwakhona ayihlali kwindawo yexabiso. Le nkqubo yeaudio ekumgangatho ophezulu inokulinganisa okugqwesileyo kwaye inokulungelelaniswa ngokuguquguqukayo ngokwesakhiwo esithile kunye neempawu ze-acoustic zeholo.

Isishwankathelo

ukukhetha isixokelelwano somgca wesandi kwiiholo zemfundo kukuzibophelela kumgangatho wokusasazwa kolwazi. Le nkqubo yeaudio yobuchwephesha iqinisekisa ukuba isihlalo ngasinye sinesandi esilungileyo sokumamela, sivumela wonke umphulaphuli ukuba onwabele itheko lezemfundo ngokulinganayo kwaye aphumelele ngokwenene amava akumgangatho ophezulu wokutshintshiselana kwezemfundo "wokulingana phambi kwesandi". Oku akukona nje ukhetho lobugcisa, kodwa kunye nokuqonda okunzulu kunye nentlonipho yexabiso lokutshintshiselana kwezemfundo.
