'Izwi Lomphefumulo' Kumabhayisikobho Angasese: Kungenziwa kanjanii-subwoofer yobungcwetiukwenza amacebo amabhayisikobho agxile kakhulu ezinhliziyweni zabantu?

Ucwaningo lubonisa ukuthiimiphumela ye-bass esezingeni eliphezulukungandisa ukucwiliswa kokubukela ngo-60% kanye nokuqina kwemizwa ngo-45%

Lapho kuvela indawo yokuqhuma ku-movie,i-subwooferakugcini nje ngokulethaumsindo, kodwa futhi nokushaqeka okushaya inhliziyo; Lapho ukushaya kwenhliziyo komlingiswa oyinhloko kushesha, ukushaya kwenhliziyo okudluliselwa yi-subwoofer kwenza izilaleli zibe nozwela. Emabhayisikobho angasese, umphefumulo weizinhlelo zomsindo zobungcwetikuvela ekulawuleni okunembile kokuzwakala kwemizwa yi-subwoofer.

I-subwoofer idlala indima yenjini yemizwa kuma-cinema azimele. Ngokusebenzisa ukushayela okunembileama-amplifier edijithali, i-subwoofer ingabuyisa imininingwane ecebile yemvamisa ephansi ngaphakathi kwebanga eliphakathi kuka-20Hz-120Hz. Kungakhathaliseki ukuthi umsindo ojulile wemigodi emnyama ku-Interstellar noma ukuwa kwemvamisa ephansi okushaqisayo kwamaphupho ku-Inception, angavezwa kahle. Ukuphathwa okuhlakaniphile kweiprosesakuqinisekisa ukuxhumana okuphelele phakathi komphumela wemvamisa ephansi kanye nemvamisa ephakathi kuya phezulu yeisikhulumi sekholomu, okudala ukungabi nazihibeinsimu yomsindookuhlangenwe nakho. Okuphawulekayo ubuchwepheshe bokusebenza ngokubambisana obusetshenziswa kumayunithi amaningi ku-subwoofer yesimanje, obuqeda ngempumelelo ukuphambuka kwe-resonance ngokusebenzisa izakhiwo ze-acoustic ezibalwe ngokunembile, ukuqinisekisa ukuthi yonke imininingwane yemvamisa ephansi icacile futhi iyahlukaniswa.

I-sequencer yamandlaIdlala indima eqondile yokuvumelanisa ohlelweni. Iqinisekisa ukuthi umphumela wokushaqeka we-subwoofer uvezwa ngokuvumelana nesakhiwo esibonakalayo ngama-millisecond: umsindo wokuqhuma kanye nokuqhuma komlilo kuhambisana ngokushesha, futhi izithombe zokuduma nombani zihambisana kahle. Lokhu kulawula isikhathi okunembile kuvumela izethameli ukuthi zizicwilise ngokuphelele ezweni le-audiovisual elidalwe ngumqondisi. I-sequencer yamandla ethuthukisiwe nayo inomsebenzi wokufunda ohlakaniphile, ongenza ngcono ngokuzenzakalelayo amapharamitha okulibaziseka ngokohlobo lwe-movie, okuvumela ukuvumelanisa komsindo nevidiyo kufinyelele esimweni esihle kakhulu.

Iumxube womsindoivumela abanikazi bama-cinema ukuthi benze ngokwezifiso ukuhleleka ngokwezinhlobo zefilimu. Ngokulungisa okunembile komxube womsindo, ama-movie ezenzo angabonisa imiphumela yemvamisa ephansi, kuyilapho amafilimu obuciko engaveza imiphumela ebucayi kakhulu yemvamisa ephansi ngokomzwelo. Hlola umsebenzi wokulinganisa umsindo ozenzakalelayo weimakrofoningokubambisana neprosesa, engenza ngcono ngokuzenzakalelayo impendulo yemvamisa ye-subwoofer ngokusekelwe ku-izici ze-acoustickwegumbi futhi kuqedwe ukuphazamiseka kwamagagasi amile.

Umsebenzi wokubambisana weuhlelo lwesikhulumi lochwepheshekwandisa ukusebenza kahle kwe-subwoofer. Isikhulumi sekholomu sinomthwalo wemfanelo wokuletha ingxoxo ecacile kanye nobucikoimiphumela yomsindo, kuyilapho i-subwoofer igxile ekudaleni isimo esingokomzwelo. Lokhu kuhlukaniswa kwabasebenzi kanye nokubambisana kuvumela ama-cinema azimele ukuthi aveze izigcawu eziqhumayo ezijabulisayo kanye nezikhathi zengxoxo ezithinta inhliziyo.

Ngamafuphi, i-subwoofer kuma-cinema angasese ingaphezu nje kwe-idivayisi yomsindo, kuyibhuloho elixhumanisa imizwa yefilimu nezinhliziyo zezilaleli. Ngokuqhutshwa okunamandla kwama-amplifier edijithali, ukuphathwa okuhlakaniphile kweamaprosesa, ukuvumelanisa okunembile kweama-sequencer wamandla, ukulungiswa okwenziwe ngokwezifiso kweizihlanganisi zomsindo, kanye nokulinganiswa kwesayensi kokuhlolwaamamakrofoni, i-subwoofer ishiya uphawu olujulile kuyo yonke indaba yefilimu ezinhliziyweni zezilaleli. Ukutshala imali ku-uhlelo lomsindo lochwephesheifakwe i-i-subwoofer yekhwalithi ephezuluifaka "izwi elithinta inhliziyo" kakhulu kuma-cinema angasese.
