T"njira yosinthira malo" yasubwoofer: zingatheke bwanjimakina ojambulira mawu a akatswiri a kanemakukwaniritsa phokoso lalikulu la zochitika zazikulu m'zipinda zazing'ono?

Umboni wa sayansi ukusonyeza kuti kuyang'anira bwino ma frequency otsika kungawonjezere kuzama m'ma cinema ang'onoang'ono ndi 60%, pomwe kuchepetsa kusokonezeka kwa mafunde oyima ndi 80%

Mu malo ochitira zisudzo kunyumba osakwana 20 sikweya mita, makina achikhalidwe a bass nthawi zambiri amakumana ndi vuto: voliyumu yotsika siigwedezeka, pomwe voliyumu yayikulu imapanga phokoso lakuda ndi mafunde oyima oyima. Masiku ano, amakina omveka bwino aukadaulokutengera zenizenimawu omvekaKuwerengera kukulembanso malamulo a mawu a m'makanema ang'onoang'ono kudzera muukadaulo wanzeru wa subwoofer komanso kukonza ma signal apamwamba.

Kukonza malo bwino kwamakina omvetsera aukadauloAmayamba ndi mapu olondola a mawu. Akatswiri amagwiritsa ntchito kuyezamaikolofonikuchita kusanthula chipindacho ndi mfundo zambiri, ndipurosesaimakhazikitsa chitsanzo cha mawu cha magawo atatu kutengera deta yosonkhanitsidwa kuti izindikire molondola mafupipafupi a resonance ndi mafunde oyima m'chipindamo. Deta iyi imagwira ntchito ngati pulani yoyambira ya subwoofer system kuti ichitike 'kusintha malo'. Ntchito yogwirizana yama amplifiers a digitondiakatswiri ma amplifierszimaonetsetsa kuti mphamvu ya ma frequency otsika ikhoza kulamulidwa bwino m'malo mokulitsidwa mosazindikira, zomwe ndi chinsinsi chopezera ma frequency otsika omveka bwino m'malo ang'onoang'ono.

Kulamulira kwa millisecond synchronization kwamphamvusequencerimathetsa vuto la gawo m'malo ang'onoang'ono. Chifukwa cha kukula kochepa kwa chipindacho, kusiyana kwa nthawi pakati pa phokoso lolunjika ndi phokoso lowonetsedwa ndi kochepa kwambiri, ndipo kuchedwa kosayenera kungayambitse kuletsa kwakukulu kwa gawo.mphamvusequencer imatsimikizira kufananiza kolondola kwaphokososnthawi yopangira pakati pa chachikuluwokamba nkhanindi subwoofer, zomwe zimathandiza kuti phokoso la gulu lililonse la ma frequency lifike pamalo omvetsera nthawi imodzi. Uwu ndiye maziko aukadaulo opezera ma frequency otsika omveka bwino komanso ang'onoang'ono.

Chiyambi chawanzeruchosakanizira mawuyapangitsa kuti kasamalidwe ka sinema ya malo ang'onoang'ono kakhale kosavuta kuposa kale lonse. Kusintha kwachikhalidwe kwa magawo ovuta kwasinthidwa kukhala njira zowoneka bwino: mawonekedwe a "action blockbuster" amawonjezera mphamvu yamphamvu ya ma frequency otsika osakhalitsa, mawonekedwe a "kuyamikira nyimbo" amayang'ana kwambiri kusinthasintha ndi kusinthasintha kwa ma frequency otsika, ndipo "night mode" imasunga kuchuluka kwa ma frequency otsika pomwe ikuchepetsa voliyumu yonse. Ogwiritsa ntchito amatha kusintha mosavuta kudzera mu mawonekedwe anzeru, ndipurosesas kumbuyo kwake kudzakwaniritsa zokha kusintha kolondola kwa magawo ambiri.

ChopitilirakuwunikaKuyeza maikolofoni kumapereka mwayi wokonzanso makinawo. Maikolofoni yowunikira zachilengedwe yomwe ili ndi makina amakono a sinema imatha kutsatira kusintha kwa mawu mchipindamo nthawi yeniyeni - mipando yamkati ikasuntha kapena antchito akawonjezeka kapena kuchepa, makinawo adzayambiranso okha.setimakhalidwe otulutsa a subwoofer. Zotsatira za kusintha kwa kutentha ndi chinyezi pa liwiro la mawu zidzalipidwanso nthawi yeniyeni kuti zitsimikizire kuti kukonza kwa mawu kumakhala kogwira mtima nthawi zonse.

Makina omvetsera aukadaulo apamwamba kwambirizimasonyeza kufunika kwawo kwakukulu mu gawo lomaliza la kukonza malo. Pamene subwoofer ilumikizidwa bwino ndiwokamba nkhani wamkulu, zonsegawo la mawuimapereka kusinthasintha kodabwitsa - kaya ndi ma frequency otsika kwambiri omwe amadzazidwa ndi mabowo akuda mu Interstellar kapena mafunde opondereza a ndege zankhondo zomwe zimadumphira ku Dunkirk, zitha kubwerezedwanso molondola pamalo ang'onoang'ono pamlingo wa sinema.maikolofoni opanda zingweChogwiritsidwa ntchito mu dongosololi sichimangogwiritsidwa ntchito powongolera mawu tsiku ndi tsiku, komanso chimagwira ntchito yofunika kwambiri pakukonza mawu okha: ogwiritsa ntchito amangofunika kugwira maikolofoni opanda zingwe ndikuyisuntha pamalo omvetsera, ndipo dongosololi limatha kutsiriza kuyeza kwa mfundo zambiri ndikukonza mwanzeru magawo a balance a frequency band iliyonse. Kusintha kwaukadaulo "kopanda nzeru" kumeneku kumalola ogula wamba kupeza mosavuta zotsatira zabwino zomwe akatswiri a acoustic adakonza.

Mwachidule, kukonza bwino malo owonera makanema ang'onoang'ono amakono pogwiritsa ntchito pafupipafupi kwasintha kuchoka pa zida zosavuta kupita ku dongosolo lathunthu lasayansi lomwe limagwirizanitsamawu apamwamba kwambiri aukadaulozida zamagetsi, kasamalidwe kanzeru ka subwoofer, chowongolera cholondola cha ma amplifiers aukadaulo, kusintha bwino ma amplifiers a digito, kukonza algorithm ya purosesa, kulunzanitsa kolondola kwamphamvuofufuza, ndi muyeso wanzeru wamaikolofoni opanda zingweNjira yosinthira malo iyi sikuti imangothetsa zofooka zamkati mwa zipinda zazing'ono, komanso imalowetsa mwayi wopanda malire wa mawu m'malo ochepa kudzera muukadaulo wanzeru. Ndikoyenera kunena kuti maikolofoni opanda zingwe omwe ali mu dongosololi amafewetsa njira yogwirira ntchito pomwe akutsimikizira ukatswiri ndi kulondola kwa kuwerengera - ogwiritsa ntchito amatha kupeza zotsatira zabwino kudzera mu kuwerengera kolondola ndi ntchito zosavuta, kukwaniritsa bwino pakati pa ukadaulo waukadaulo ndi zomwe ogwiritsa ntchito akumana nazo. Imalola banja lililonse kumva phokoso lalikulu komanso kumva kofanana ndi makanema aukadaulo m'malo ochepa, ndikumaliza kusintha kwabwino kuchokera pa "kumveka" mpaka "kodabwitsa".
