Idatha yovavanyo lobuchwephesha ibonisa ukubainkqubo yesandi yoluhlu lwemigcainokulawula ukufana kwentsimi yesandi kwiindawo ezinkulu ngaphakathi kwe-± 3 decibels, kwaye isalathisi sokudlulisa ilizwi sifikelela kwinqanaba eliphezulu le-0.75

Eyona nto ibuhlungu kakhulu yemveliiinkqubo zesandikwiindawo zemidlalo ezinabantu abaninzi okanye kwiindawo ezivulekileyo kukubaisandiibola ngokukhawuleza xa umgama usiya kumgama – ngokomthetho wesikwere esichaseneyo, inqanaba loxinzelelo lwesandi liyancipha ngee-decibels ezi-6 kumgama ngamnye ophindwe kabini, oko kuthetha ukuba ivolumu eviwa ngabaphulaphuli abangasemva inokuba yikota kuphela yeyomgca ongaphambili. Kule mihla, iinkqubo zesandi ezisekwe kubuchwepheshe bokwenza imisebe ziyayitshintsha ngokupheleleyo le meko, zifezekisa “intando yesininzi yokuva” ngokusebenzisaindawo yesandi echanekileyoulawulo.

Impumelelo yeiinkqubo zesandi zobungcalikuxhomekeke ekwakheni ngokutsha kwenzululwazi indlela yokusasazwa kwamaza esandi.izithethi ze-line arraysebenzani kunye ngokusebenzisa iindlela ezininzi ezicwangciswe ngokuthe nkqoisithethiiiyunithi zokuvelisa imisebe ye-cylindrical ekhokelela kwicala eliphezulu. Olu hlobo lwezandi lunokukhokelwa ngokuchanekileyo njengomsebe wethotshi, lujolise amandla kwaye luwaphose kwindawo ekhethiweyo, luphephe inkunkuma yamandla esibhakabhakeni nakwiindawo ezingasebenziyo. Kwizicelo ezisebenzayo, isandi esiyilwe ngononopheloisithethi se-line arrayinokuhambisa ngaphezulu kwe-80% yamandla esandi kwindawo ekujoliswe kuyo abaphulaphuli, ngelixa ipesenti yomthombo wenqaku wendabukoizithethiidla ngokuba ngaphantsi kwama-50%. Uyilo lwentsebenziswanoii-amplifier zobungcalikwayeii-amplifier zedijithaliInika isiqinisekiso samandla esifunekayo kwinkqubo. Eyokuqala iqinisekisa ukuphuma koxinzelelo lwesandi oluphambili, ngelixa eyesibini iqhuba ngokufanelekileyo iinkqubo ezincedisayo. Olu dibaniso lunciphisa kakhulu ukusetyenziswa kwamandla ngelixa luqinisekisaumgangatho wesandi.

Iiprosesayi-core ekrelekrele evumela ulawulo oluchanekileyo lwentsimi yesandi. Ngaphambi kokufakwa kwenkqubo, iingcali zisebenzisa ukulinganisaiimayikrofoniukuqokelelai-acousticidatha kwiindawo ezininzi kwindawo leyo, kwaye iprosesa yakha imodeli ye-acoustic enemilinganiselo emithathu ngokusekelwe kolu lwazi. Le modeli ibala ngokuchanekileyo i-engile yokumiswa efanelekileyo, i-engile yokuthambeka, kunye neeparameter zokulibaziseka zesithethi ngasinye somgca. Ukusetyenziswa okusebenzayo, iprosesa ilawula ngokuguquguqukayo umsebenzi wokubambisana wazo zonke iiyunithi ngokusebenzisai-power sequencer– xa kufunyenwe indawo ethile enobuninzi babaphulaphuli, iyunithi yomgca ohambelanayo iya kuyiphucula ngokuzenzekelayo imveliso; Xa kuhlangatyezwana nomoya ovuthuzayo okanye utshintsho lomswakama, inkqubo iya kulungisa impendulo yefrikhwensi ngexesha langempela ukuze ihlawulwe. Oku kuguquguquka okukrelekrele kwenza inkqubo ikwazi ukugcina ukusebenza kakuhle phantsi kweemeko ezahlukeneyo zokusingqongileyo.

Uqwalaselo lwei-subwooferifuna ukuqwalaselwa ngokukodwa kwiindawo ezinkulu. I-subwoofer enye yendabuko idla ngokuvelisa ukusasazwa okungalinganiyo kwe-low-frequency kwiindawo ezibanzi, ngelixa izisombululo zanamhlanje zamkela ii-arrays ze-subwoofer ezisasaziweyo. Ngolawulo olukrelekrele lweprosesa, iiyunithi ezininzi ze-subwoofer zisebenza kunye ukwenza ukugubungela okufanayo kwe-low-frequency kwindawo yabaphulaphuli. Oku akupheleli nje ekunyuseni isiphumo esothusayo somculo, kodwa okubaluleke ngakumbi, kubonelela ngenkxaso esisiseko yentetho - izinto ze-low-frequency kwilizwi lomntu (ingakumbi ilizwi lendoda) zinokuphucuka ngaphezulu kwe-30% emva kokuphuculwa okufanelekileyo.

Iinkqubo zeemakrofoni ezingenazingcingobajongene nemingeni ekhethekileyo kwiindawo ezinkulu.imakrofoni engenazingcingo ephathwa ngesandla yobungcaliyamkela iteknoloji yokwamkela umahluko webhendi ye-UHF kunye nenkqubo ye-antenna ekhokelayo, enokugcina unxibelelwano oluzinzileyo kwiindawo ezintsonkothileyo ze-electromagnetic.imakrofoniixhotyiswe ngetshiphusi ekrelekrele ekwaziyo ukubona indawo yomsebenzisi kunye nomgama ngexesha langempela – inciphisa ngokuzenzekelayo inzuzo xa isithethi sisondela kwindawo ephambiliizithethi, kwaye uyinyuse ngokufanelekileyo xa isuka, ukuqinisekisa ukuba isandi sihlala sicacile kwaye sizinzile. Xa kuphindaphindwaiimayikrofonixa zisetyenziswa ngaxeshanye, i-algorithm yokuxuba ngokuzenzekelayo yeprosesa ilinganisela ngobuchule ivolumu yemakrofoni nganye ukuze kuthintelwe iimeko apho amazwi ezinye izithethi ebonakala kakhulu ngelixa ezinye zingenamsebenzi.

Ujongano lokusebenza lweumxube weaudio okrelekreleYenzelwe ngononophelo ukuguqula ulawulo oluntsonkothileyo lobuchwephesha lube lulawulo lweendawo oluqondakalayo. Umsebenzisi angakhetha "imo yezemidlalo" esetwe kwangaphambili, "imo yekonsathi" okanye "imo yenkomfa" ngesikrini sokuchukumisa, kwaye inkqubo iya kuzigqibezela ngokuzenzekelayo zonke izicwangciso zeparameter. I-power sequencer iqinisekisa ukuba ulandelelwano lwamandla okuqala kwesixhobo ngasinye luhambelana ngokupheleleyo ngexesha lenkqubo yokutshintsha imo, ukuthintela ukuphumaizandiokanye ukuphazamiseka kwesignali. Umxubi wesandi ophucukileyo ukwaxhasa intsebenziswano yabaqhubi abaninzi, ukufezekisa unxibelelwano olungenamthungo lweekhonkco ezahlukeneyo zesandi kwimicimbi emikhulu.

Ngamafutshane, isisombululo se-acoustic kwiindawo ezinkulu zanamhlanje sisixhobo sobunjineli benkqubo esidibanisa ukukhomba ngokuchanekileyo izithethi zemigca, ulawulo olukrelekrele lweiiprosesa, ukuqhuba okuzinzileyo kwee-amplifier zobungcali, ukuguqulwa okusebenzayo kwee-amplifier zedijithali, ukuhambelana ngokuchanekileyo kweabalandelelanisi bamandla, ukugqunywa okufanayo kwe-subwoofer, ukuhanjiswa okuthembekileyo kweemakrofoni ezikrelekrele, kunye nokusebenza okulula kweabaxubi besandiLe nkqubo "yentsimi yesandi esifanelekileyo" ayigcini nje ngokugqitha imida yendawo ebonakalayo ekusasazweni kwesandi, kodwa ikwafezekisa ukuhanjiswa kolwazi ngokulinganayo ngokusebenzisa ubuchwepheshe obutsha. Ibonelela ngamava okumamela afanayo phantse kuzo zonke izihlalo kwindawo, isusa umgama njengomqobo ekufikeleleni kulwazi. Kwiminyhadala emikhulu yanamhlanje eyanda rhoqo kunye nokuphucula rhoqo iimfuno zamava abaphulaphuli, ukutyala imali kwi-inkqubo yesandi yobungcaliayikokufuna nje inkqubela phambili kwezobuchwepheshe, kodwa ikwayintlonipho nesiqinisekiso samalungelo okuva awo onke amalungu abaphulaphuli.
