T"indlela yokushintsha indawo" yei-subwoofer: kanjaniizinhlelo zomsindo zesinema zobungcwetiukufeza umsindo okhulayo wezigcawu ezinkulu emakamelweni amancane?

Ubufakazi besayensi bubonisa ukuthi ukuphathwa okunembile kwemvamisa ephansi kungandisa ukucwiliswa kuma-cinema amancane asemkhathini ngo-60%, kuyilapho kunciphisa ukuphazamiseka kwamagagasi okuma ngo-80%

Endaweni yeshashalazi yasekhaya engaphansi kwamamitha-skwele angama-20, izinhlelo zebhasi zendabuko zivame ukubhekana nenkinga: umsindo ophansi awunawo uvalo, kuyilapho umsindo ophezulu uveza ukuduma okufiphele namagagasi amile acasulayo. Namuhla, i-uhlelo lomsindo lochwepheshengokusekelwe kokunembai-acousticizibalo zibhala kabusha ngokuphelele imithetho ye-acoustic yama-cinema amancane ngokusebenzisa ubuchwepheshe be-subwoofer obuhlakaniphile kanye nokucubungula amasignali okuthuthukisiwe.

Ukuthuthukiswa kwendawoizinhlelo zomsindo zobungcwetiiqala ngokumapha okunembile kwe-acoustic. Ochwepheshe basebenzisa ukulinganisaamamakrofoniukwenza ukuskena kwamaphuzu amaningi ekamelweni, kanyeiprosesaisungula imodeli ye-acoustic enezinhlangothi ezintathu esekelwe kudatha eqoqwe ukuze ibone ngokunembile imvamisa ye-resonance kanye nama-standing wave nodes egumbi. Le datha isebenza njengohlaka oluyisisekelo lwesistimu ye-subwoofer ukuze 'iguqulwe kabusha'. Umsebenzi wokubambisana weama-amplifier edijithalifuthiuchwepheshe ama-amplifieriqinisekisa ukuthi amandla anemvamisa ephansi angalawulwa ngokunembile kunokuba akhuliswe ngokungaboni, okuyisihluthulelo sokuthola imvamisa ephansi ecacile ezindaweni ezincane.

Ukulawulwa kokuvumelanisa kwezinga le-millisecond kweamandlai-sequencerixazulula inkinga yesigaba ezindaweni ezincane. Ngenxa yobukhulu obuncane begumbi, umehluko wesikhathi phakathi komsindo oqondile nomsindo oboniswayo mfushane kakhulu, futhi izilungiselelo zokulibaziseka ezingafanele zingaholela ekukhanselweni okukhulu kwesigaba.amandlai-sequencer iqinisekisa ukuhambisana okunembile kweumsindosisikhathi sokukhiqiza phakathi kwesiqalo esiyinhlokoisikhulumikanye ne-subwoofer, okuvumela umsindo webhendi ngayinye yemvamisa ukuthi ifinyelele indawo yokulalela ngasikhathi sinye. Lesi yisisekelo sobuchwepheshe sokuthola imvamisa ephansi ecacile nencane.

Isingeniso sikauhlakaniphileumxube womsindokwenze ukuphathwa kwe-cinema yesikhala esincane kwaba lula kakhulu kunanini ngaphambili. Ukulungiswa kwepharamitha okuyinkimbinkimbi kwendabuko kwenziwe lula kwaba izindlela zesigcawu ezinembile: imodi "ye-action blockbuster" ithuthukisa umthelela onamandla wemvamisa ephansi yesikhashana, imodi "yokwazisa umculo" igxile ekuqineni nasekuhlelekeni kwemvamisa ephansi, kanti "imodi yasebusuku" igcina ububanzi obuguquguqukayo bemvamisa ephansi ngenkathi inciphisa ivolumu iyonke. Abasebenzisi bangashintsha kalula ngokusebenzisa isikhombikubona esihlakaniphile, kanyeiprosesas ngemuva kwayo kuzoqedela ngokuzenzakalelayo ukulungiswa okunembile kwamapharamitha amaningi.

Okuqhubekayoukuqaphayokulinganisa amamakrofoni inikeza ithuba lokwenza ngcono uhlelo. Imakrofoni yokuqapha imvelo efakwe ezinhlelweni zesinema zesimanje ingalandelela izinguquko ze-acoustic zesikhathi sangempela ekamelweni - lapho ifenisha yangaphakathi inyakaza noma abasebenzi benyuka noma bencipha, uhlelo luzophinde lusebenze ngokuzenzakalelayoisethiizici zokukhipha ze-subwoofer. Umthelela wokushintsha kwezinga lokushisa kanye nomswakama esivinini somsindo uzophinde unxeshezelwe ngesikhathi sangempela ukuqinisekisa ukusebenza okuhlala njalo kokulungiswa kwe-acoustic.

Izinhlelo zomsindo zobungcweti ezisezingeni eliphezulubabonisa inani labo elivelele esigabeni sokugcina sokwenza ngcono isikhala. Uma i-subwoofer ihlanganiswe kahle ne-isikhulumi esiyinhloko, konkeinsimu yomsindoiveza ukuvumelana okumangalisayo - kungakhathaliseki ukuthi amaza aphansi ajulile agcwele imigodi emnyama ku-Interstellar noma amaza omsindo acindezelayo ezindiza zempi ezicwila eDunkirk, zingakhiqizwa ngokunembile endaweni encane ezingeni lesinema.imakrofoni engenantamboIfakwe ohlelweni ayisetshenziselwa ukulawula izwi nsuku zonke kuphela, kodwa futhi idlala indima ebalulekile ekulinganisweni kwezwi okuzenzakalelayo: abasebenzisi badinga kuphela ukubamba imakrofoni engenantambo bese beyihambisa endaweni yokulalela, futhi uhlelo lungaqedela ngokuzenzakalelayo ukulinganisa kwamaphuzu amaningi futhi luthuthukise ngobuhlakani amapharamitha ebhalansi yebhendi ngayinye yemvamisa. Lokhu kulungiswa kobungcweti "okungavimbeli" kuvumela abathengi abavamile ukuthola kalula umphumela ophelele olungisiwe ochwepheshe be-acoustic.

Ngamafuphi, ukwenziwa ngcono kwama-cinema amancane esimanje ngendlela ephansi kuye kwashintsha kusuka ekubeni yi-stack yemishini elula kuya ohlelweni oluphelele lwesayensi oluhlanganisayoumsindo wobungcweti wekhwalithi ephezuluihadiwe, ukuphathwa kwe-subwoofer okuhlakaniphile, umshayeli oqondile wama-amplifier ochwepheshe, ukuguqulwa okuphumelelayo kwama-amplifier edijithali, ukulungiswa kwe-algorithm yeprosesa, ukuvumelanisa okunembile kweamandlaama-sequencer, kanye nokulinganisa okuhlakaniphile kweimakrofoni engenantamboLe ndlela yokushintsha indawo ayixazululi nje kuphela imikhawulo ye-acoustic yamakamelo amancane, kodwa futhi ifaka amathuba angenamkhawulo e-acoustic ezindaweni ezilinganiselwe ngobuchwepheshe obuhlakaniphile. Kuhle ukusho ukuthi imakrofoni engenantambo efakwe ohlelweni yenza inqubo yokusebenza ibe lula ngenkathi iqinisekisa ubungcweti kanye nokunemba kokulinganiswa - abasebenzisi bangathola imiphumela elungiselelwe ngokubala okunembile ngemisebenzi elula, bafinyelele ngempela ibhalansi ephelele phakathi kobuchwepheshe bochwepheshe kanye nesipiliyoni somsebenzisi. Ivumela yonke imindeni ukuzwa umsindo okhuphukayo kanye nomuzwa ojulile ofana nama-cinema ochwepheshe endaweni elinganiselwe, iqedela ijubane lekhwalithi kusukela "elizwakalayo" kuya "elishaqisayo".
