Idatha ibonisa ukuba iinkqubo zesandi ezisemgangathweni ophezulu zinokunyusa ukuhamba kwabathengi kwiindawo zokuthenga ngama-40% kwaye zandise ixesha lokuhlala kwabathengi ngama-35%

Kwindawo ephithizelayo yevenkile enkulu, kwakusenziwa umboniso omhle kakhulu, kodwa ngenxa yezandi ezingalunganga, abaphulaphuli bafinge iintshiyi baza bemka omnye emva komnye – umboniso ophindaphindwayo yonke imihla kwiindawo ezinkulu zokuthenga. Enyanisweni, inkqubo yesandi esisemgangathweni ophezulu ayisiyonkxaso yobugcisa kwimicimbi kuphela, kodwa ikwayinto ephambili ekuphuculeni umfanekiso wentengiso yevenkile enkulu kunye nokutsala abathengi. 

Imingeni yesandi kwindawo yeevenkile ezinkulu inzima kakhulu: ii-echoes ezinzima eziveliswa zii-silings eziphakamileyo, ingxolo yendalo ebangelwa zizihlwele ezingxolayo, i-reflection yesandi ebangelwa ziindonga zekhethini zeglasi kunye nemigangatho yemabula... zonke ezifuna iinkqubo zesandi zobuchwephesha ukuze zijongane nazo. Izithethi ze-linear, ezinobuchule bazo bokulawula indlela, zinokuthumela ngokuchanekileyo amandla esandi kwindawo ekujoliswe kuyo, zinciphise i-reflection yendalo kwaye ziqinisekise ukuba nakwiindawo zeevenkile ezinkulu ezinengxolo, yonke inqaku inokudluliselwa ngokucacileyo.

Ukukhetha inkqubo yemakrofoni kubaluleke ngokulinganayo. Imiboniso yeevenkile ezinkulu ifuna iimakrofoni zobungcali ezinokucinezela ingxolo yokusingqongileyo kwaye zithintele ukubethela umlozi. Iimakrofoni ezingenazingcingo ze-UHF zinamandla okudlulisa isignali azinzileyo kunye neempawu ezibalaseleyo zokulwa nokuphazamiseka, ziqinisekisa amazwi acacileyo nazinzileyo kubabuki kunye nabadlali. Imakrofoni exhonywe entloko ikhulula izandla zabadlali, iyenza ifaneleke ngokukodwa kwimiboniso yengoma nomdaniso kunye nemisebenzi yokusebenzisana.

Iprosesa yedijithali 'yingqondo ekrelekrele' yenkqubo yonke. Inkqubo yesandi yevenkile enkulu kufuneka iphathe iindlela ezahlukeneyo zokusebenza: isenokuba yipiyano ethule yodwa okanye ukusebenza kwebhendi ephilayo. Iprosesa ekrelekrele inokugcina iindlela ezininzi ezicwangcisiweyo kwaye itshintshe iiparameter ze-acoustic kwiindawo ezahlukeneyo zokusebenza ngokucofa kube kanye. Okubaluleke ngakumbi, iprosesa inokujonga imeko yendawo yesandi ngexesha langempela, ilungise ngokuzenzekelayo iiparameter zokulinganisa, kwaye ibuyisele iziphene ze-acoustic ezibangelwa zizakhiwo ezikhethekileyo kwiindawo zokuthenga ezinkulu.

Inkqubo yesandi yokusebenza kwevenkile enkulu yokuthenga ikwafanele iqwalasele iimfuno zokufakwa ngokukhawuleza kunye nokufakelwa okufihliweyo. Inkqubo yesandi yemigca efihliweyo inokufihlakala ngokupheleleyo ngexesha lokungasebenzi, igcina ubuhle bevenkile enkulu yokuthenga; Inkqubo yokudibanisa ngokukhawuleza inciphisa ixesha lokuseta isixhobo ngama-50% kwaye iphucula kakhulu ukusebenza kakuhle kokulungiselela iziganeko.

Ngamafutshane, ukutyala imali kwinkqubo yesandi sokusebenza sevenkile yokuthenga enobuchule kungaphezulu kakhulu kokuthenga izixhobo. Sisisombululo esipheleleyo esidibanisa ukuqikelelwa ngokuchanekileyo kwezithethi ezicwangcisiweyo, ukuchongwa okucacileyo kweemakrofoni zobungcali, kunye nolawulo oluchanekileyo lweeprosesa ezikrelekrele. Le nkqubo yesandi ekumgangatho ophezulu ayiqinisekisi nje kuphela ukubonakaliswa okugqibeleleyo kwayo yonke imisebenzi, kodwa ikwanyusa ngokufanelekileyo ukuhamba kwabathengi kunye nexesha labo lokuhlala kwivenkile, idala ixabiso elikhulu kwiindawo zorhwebo. Ngexesha loqoqosho lwamava, inkqubo yesandi sokusebenza yobungcali iba sisixhobo esibalulekileyo kwiivenkile zokuthenga zanamhlanje ukuphucula ukhuphiswano.
