I-'Voice of the Soul' kuma-cinema angasese: Ungawenza kanjanii-subwoofer yochwephesheukwenza izinhlelo zamabhayisikobho zigxile ngokujulile ezinhliziyweni zabantu?

Ucwaningo lubonisa lokhoimiphumela ye-bass ephezuluingakhuphula ukucwiliswa kokubuka ngo-60% kanye nokuzwakala kwemizwa ngo-45%

Lapho isigcawu sokuqhuma sifika ku-movie, ii-subwooferhhayi kuphela ukulethaumsindo, kodwa futhi nokushaqeka okushaya inhliziyo; Lapho ukushaya kwenhliziyo komlingiswa oyinhloko kushesha, ukushaya kwenhliziyo okudluliselwa yi-subwoofer kwenza izethameli zizwele. Emabhayisikobho angasese, umphefumulo weamasistimu omsindo ochwephesheivela ekulawuleni okunembile kwe-resonance yemizwa nge-subwoofer.

I-subwoofer idlala indima yenjini yemizwa kumasinema angasese. Ngokushayela okunembe kweama-amplifiers edijithali, i-subwoofer ingabuyisela imininingwane ecebile yefrikhwensi phakathi kwebanga elingu-20Hz-120Hz. Kungakhathaliseki ukuthi ukubhonga okujulile kwezimbobo ezimnyama ku-Interstellar noma ukuwohloka okushaqisayo kwe-low-frequency kwamaphupho ku-Inception, angasethulwa kahle kakhulu. Ukuphathwa okuhlakaniphile kweiprosesaiqinisekisa ukuxhumana okuphelele phakathi komphumela we-low-frequency kanye ne-mid to high frequency of theisipikha sekholomu, ukudala i-seamlessinkambu yomsindoOkuhlangenwe nakho.Okuphawuleka ngokukhethekile ubuchwepheshe bokusebenzisana obuhlangene beyunithi obusetshenziswa ku-subwoofer yesimanje, obuqeda ngempumelelo ukuhlanekezela kwe-resonance ngokusebenzisa izakhiwo ze-acoustic ezibalwe kahle, okuqinisekisa ukuthi yonke imininingwane yefrikhwensi ephansi icacile futhi iyahlukaniseka.

Isilandeleli samandlaidlala indima eqondile yokuvumelanisa ohlelweni. Iqinisekisa ukuthi umthelela wokushaqisa we-subwoofer uvezwa ngokuvumelanisa nesakhiwo esibukwayo ngama-millisecond: umsindo wokuqhuma nokuqhuma komlilo kufanelana ngaso leso sikhathi, futhi ukuduma kwezulu nemifanekiso yombani kufanelana ngokuphelele. Lokhu kulawula isikhathi okunembayo kuvumela izethameli ukuthi zicwilise ngokugcwele emhlabeni wokulalelwayo nokubukwayo odalwe umqondisi.Isilandeleli samandla esithuthukisiwe siphinde sibe nomsebenzi wokufunda ohlakaniphile, ongathuthukisa ngokuzenzakalelayo imingcele yokubambezeleka ngokohlobo lwefilimu, okuvumela ukuvumelanisa komsindo nevidiyo ukuthi kufinyelele esimweni esingcono kakhulu.

Ii-audio mixerivumela abanikazi besinema ukuthi benze ukushuna ngokwezifiso ngokohlobo lwefilimu. Ngokulungiswa okunembile kwesihlanganisi somsindo, amamuvi esenzo angabonisa imiphumela yefrikhwensi ephansi, kuyilapho amafilimu obuciko ethula imiphumela ethambile yemizwa yemvamisa ephansi. Hlola ukusebenza kokulinganisa komsindo okuzenzakalelayo kweumbhobhongokubambisana neprosesa, engakwazi ukwenza ngcono ngokuzenzakalelayo ukusabela kwemvamisa ye-subwoofer ngokusekelweizici ze-acousticwegumbi futhi uqede ukuphazamiseka kwamagagasi okuma.

Umsebenzi wokubambisana weuhlelo lwesipikha esichwepheshileikhulisa ukusebenza kahle kwe-subwoofer. Isipikha sekholomu sinesibopho sokuletha inkhulumomphendvulwano ecacile futhi ethambilenemisindo, kuyilapho i-subwoofer igxile ekudaleni umoya womzwelo. Lokhu kuhlukaniswa kwezabasebenzi nokusebenzisana kuvumela amasinema azimele ukwethula izigcawu ezijabulisayo neziqhumayo kanye nezikhathi zezingxoxo ezithinta inhliziyo.

Kafushane, i-subwoofer kuma-cinema angasese ingaphezulu kakhulu kune-aidivayisi yomsindo, ibhuloho elixhumanisa imizwelo yefilimu nezinhliziyo zezethameli. Ngokushayela okunamandla kwama-amplifiers edijithali, ukuphathwa okuhlakaniphile kweamaprosesa, ukuvumelanisa okunembile kweabalandelanayo bamandla, ukushuna komuntu siqu kweizixube zomsindo, kanye nokulinganiswa kwesayensi kokuhlolaimibhobho, i-subwoofer ishiya isigxivizo esijulile kuso sonke isiqephu sefilimu ezinhliziyweni zezethameli. Ukutshala imali ku-aprofessional system soundifakwe ai-subwoofer yekhwalithi ephezuluijova “izwi elinomphefumulo” elithinta kakhulu kumasinema ayimfihlo.
