I-Acousticucwaningo lubonisa ukuthi izindawo ezisebenzisaizinhlelo ze-line array ezihlakaniphilekungathuthukainsimu yomsindoukufana ngaphakathi kwama-decibel angu-± 3 futhi kwandise ukucaca kwenkulumo ngo-45%

Ezinkundleni zemidlalo, ezikhungweni zemihlangano, noma ezinkundleni ezivulekile ezihlalisa izinkulungwane zabantu,izinhlelo zomsindobabhekene nenselele eyisisekelo:umsindoAmagagasi ancipha ngokwemvelo emoyeni, okwenza umugqa ongaphambili ube yisithulu kodwa umugqa ongemuva ungezwa kahle. Namuhla, izinhlelo zomsindo we-line array ezisekelwe kubuchwepheshe bokwakha imisebe zichaza kabusha imithetho ye-acoustic yezindawo ezinkulu ngokusebenzisa "ubuciko bazo bokuqondisa" obunembile.

Ukuphumelela okuyinhloko kwesipikha se-line arrayumsindokulele ekwakhiweni kabusha kwesayensi kwendlela yokusabalala kwamaza omsindo. Ngokungafani nokusabalala okuyindilinga komthombo wamaphuzu wendabukoizipikha, izipikha ze-line arraykhiqiza amaza ayisilinda aqondisa kakhulu ngokusebenzisa umsebenzi wokubambisana wamayunithi amaningi ahlelwe ngokuma. Lolu hlobo lwamaza omsindo lungaqondiswa ngokunembile njengomsebe wokukhanya kokusesha, lugxilise amandla futhi luwathumele endaweni yezilaleli, kunokuba lusakazeke esibhakabhakeni nasesikhala esingasebenzi kahle. Emkhakheni we-acoustics, lobu buchwepheshe bubizwa ngokuthi "ukwakha imisebe" - ngokusebenzisa izibalo ezinembile,amaprosesalawula isigaba kanye nobukhulu beyunithi ngayinye ukuze udale imisindo engakwazi "ukugoba" futhi ivumelane nezakhiwo ezikhethekile zezindawo ezahlukene.

Ukuqaliswa kweizinhlelo zomsindo zekhwalithi ephezuluithembele esikhungweni esinamandla sokubala. Iprosesa yesistimu yenza ukumodelwa kwe-3D kwendawo ngaphambi kokufakwa, futhi ibala ngokunembile i-engeli yokumiswa kanye namapharamitha okulibaziseka kwesipikha ngasinye se-line array ngokusekelwe kudatha yangempela ye-acoustic eqoqwe yi-elinganisayo.imakrofoniNgesikhathi semisebenzi yasendaweni,iprosesaIqapha njalo izinguquko zemvelo - izinga lokushisa, umswakama, kanye nesivinini somoya konke kuthinta isivinini somsindo. Uhlelo lulungisa ukubambezeleka kwesignali nge-sequencer ukuqinisekisa ukuthi wonke amaza omsindo afika endaweni okuqondiwe kuyo ngesikhathi esifanayo. Umklamo wokubambisana weama-amplifier ochwepheshefuthiama-amplifier edijithaliinikeza amandla azinzile, kanti eyokuqala iqinisekisa ukuphuma komsindo oyinhloko kanye neyesibili iqhuba kahle izinhlelo ezisizayo. Le nhlanganisela inciphisa kakhulu ukusetshenziswa kwamandla ngenkathi iqinisekisaikhwalithi yomsindo.

Ama-equalizerzidlala indima ekuhleleni kahle uhlelo. Izici zokumuncwa kanye nokubonakaliswa komsindo ziyahlukahluka kakhulu phakathi kwezinto zokwakha (insimbi, ingilazi, ukhonkolo) ezindaweni ezahlukene, futhi ama-equalizer angavala noma acindezele amabhendi athile emvamisa ngendlela eqondiwe. Isibonelo, izindawo ezinezindonga zamakhethini engilazi eziningi zidinga ukunciphisa ngokufanele ukubonakaliswa kwemvamisa ephezulu, kuyilapho izakhiwo zekhonkrithi zidinga ukuthuthukisa ukusebenza kwemvamisa ephakathi.isivimbeli sempenduloiqapha njalo ukuzinza kwesistimu. Uma umphathi ephethe i-imakrofoni engenantambo ephathwa ngesandlafuthi ihamba esiteji, ibona ngokuhlakanipha imvamisa engase ikhiqize ukukhala kwekhwela bese iyicindezela kusengaphambili ukuqinisekisa ukuthi umsebenzi ubushelelezi.

Izinhlelo zemakrofoni ezingenantambobabhekane nezinselele eziyingqayizivele ezindaweni ezinkulu.Amamakrofoni angenantambo aphathwa ngesandla asezingeni lobuchwepheshesebenzisa ubuchwepheshe bokwamukela ukuhlukahluka kwebhendi ye-UHF, obungagcina ukuxhumana okuzinzile ezindaweni eziyinkimbinkimbi ze-electromagnetic. Okubaluleke kakhulu, i-chip ehlakaniphile eyakhelwe kumakrofoni ingakwazi ukubona indawo yomsebenzisi kanye nebanga ngesikhathi sangempela, futhi iprosesa ilungisa ngokuzenzakalelayo amapharamitha okuzuza kanye nokulingana ngokusekelwe kulokhu - inciphisa ngokuzenzakalelayo inzuzo lapho isikhulumi sisondela esipikheni esikhulu, futhi isikhuphule ngokufanele lapho sisuka, iqinisekisa ukuthi umsindo uhlala ucacile futhi uhambisana. Umsebenzi wokubambisana we-multipleamamakrofonifuthi yaklanywa ngokucophelela, futhi uhlelo lungalinganisa ngokuzenzakalelayo ivolumu yama-microphone ahlukene, lugweme izimo lapho amanyeizipikha'amazwi avelele kanti amanye agqitshwa. Abahlakaniphileumxube womsindoinikeza opharetha isikhombikubona sokulawula esinembile. Ukulungiswa kwepharamitha okuyinkimbinkimbi kwendabuko okudinga onjiniyela abangochwepheshe ukuthi basebenze manje sekwenziwe lula kwaba izindlela eziningana ezicacile zesimo: imodi yemicimbi yezemidlalo igxile ekucaceni kokuphawula kanye nokudalwa komkhathi obukhoma, imodi yekhonsathi igcizelela ukuguquguquka kanye nokuhlelwa komculo, kanti imodi yenkomfa yenza ngcono ukucaca nokuqondakala kwezwi. Opharetha angalungisa insimu yomsindo yensimu yonke ngesikrini sokuthinta, futhi i-sequencer iqinisekisa ukuthi wonke amadivayisi asebenza ndawonye ngokwenqubo esethiwe.

Ukuzivumelanisa nezimo kwemvelo kuyikhono eliphawulekayo lesimanjeizinhlelo zomsindo zobungcwetiNgokusebenzisa amamakrofoni asakazwa kuyo yonke indawo, uhlelo lungabona izinga lokucindezela komsindo kanye nokuphendula kwemvamisa yezindawo ezahlukene ngesikhathi sangempela. Uma kutholakala ukucindezela komsindo okunganele endaweni ethile, iprosesa izolungisa ngokuzenzakalelayo ukuphuma kweyunithi ye-line array ehambisanayo; Uma kutholakala i-resonance ngemvamisa ethile, i-equalizer izokwenza ukucubungula okuqondiwe. Lokhu kulungiswa kwesikhathi sangempela kuvumela indawo ukuthi igcine ulwazi oluhle kakhulu lokulalela ngaphansi kwamazinga ahlukene okuhlala kanye nezimo zezulu.

Ngamafuphi, iuhlelo lomsindo lochwephesheizindawo ezinkulu zanamuhla seziphenduke “ubuciko bokulawula” obunembile. Ngokukhomba izikhulumi ze-line array ngendlela enembile, ukubala okuhlakaniphile kwama-processor, ukushayela okuzinzile kwama-amplifier ochwepheshe, ukuvumelanisa kwezinga le-millisecondama-sequencer wamandla, ukulungiswa okuhle kwama-equalizer, ukuvikelwa kwesikhathi sangempela kweabacindezeli bempendulo, ukuzivumelanisa nezimo kwama-microphone ahlakaniphile, kanye nokulawula okunembile kwabaxubi bomsindo, lolu hlelo luxazulula ngempumelelo izinkinga ze-acoustic ezikhona ezindaweni ezinkulu. Alugcini nje ngokukhulisa umsindo, kodwa futhi lubumba ngokunembile ukusatshalaliswa komsindo endaweni, okuvumela wonke amalungu ezilaleli - kungakhathaliseki ukuthi asesihlalweni sangaphambili esibalulekile noma endaweni yangemuva engabizi - ukuba abe nokuhlangenwe nakho okucishe kufane kokuzwa. Lokhu akukona nje ukunqoba kwezobuchwepheshe, kodwa futhi kuyindlela engcono kakhulu yomqondo "wokulingana kokuzwa", okwenza imicimbi emikhulu ibe yidili lamasiko elihlanganyelwe yisizwe sonke.
