T"nzira yekugadzirisa nzvimbo" yesubwoofer: zvingaitwa seimasisitimu enzwi emumafirimu ehunyanzvikuwana ruzha rukuru rwezviitiko zvikuru mumakamuri madiki?

Humbowo hwesainzi hunoratidza kuti kutonga kwakarurama kwemafrequency mashoma kunogona kuwedzera kunyura mumasinema madiki ne60%, ukuwo kuchideredza kupindira kwemafungu akamira ne80%

Munzvimbo yemitambo yepamba isingasviki 20 square metres, masisitimu ebhesi echinyakare anowanzo sangana nedambudziko: ruzha rwakaderera haruna kuvhunduka, nepo ruzha rwakanyanya ruchikonzera ruzha rusina kujeka uye mafungu anogumbura akamira. Mazuva ano, asisitimu yeruzha yehunyanzvizvichibva pane zvakanyatsonakaacousticKuverenga kuri kunyora patsva mitemo yeacoustic yema cinema madiki kuburikidza nehunyanzvi hwe subwoofer tekinoroji uye hunyanzvi hwepamusoro hwekugadzirisa masaini.

Kugadziriswa kwenzvimbo kwemasisitimu enzwi ehunyanzviinotanga nekugadzira mapu enzwi akanyatsojeka. Nyanzvi dzinoshandisa kuyeramaikorofonikuita scan yekamuri ine mapoinzi akawanda, uyeprocessorinogadzira modhi yeacoustic ine mativi matatu yakavakirwa padata rakaunganidzwa kuti rione nemazvo frequency ye resonance uye ma standing wave nodes emukamuri. Data iri rinoshanda sepurani yekutanga yesubwoofer system kuti iite 'spatial rechanging'. Basa rekushandira pamwe rema amplifiers edhijitariuyenyanzvi ma amplifiersinoita kuti simba remafrequency akaderera rigone kudzorwa nemazvo pane kuwedzerwa zvisina kujeka, inova kiyi yekuwana mafrequency akaderera akajeka munzvimbo diki.

Kudzora kuenderana kwemazinga e millisecondsimbasequencerinogadzirisa dambudziko rechikamu munzvimbo diki. Nekuda kwehukuru hudiki hwekamuri, musiyano wenguva pakati peruzha rwakananga neruzha rwunoratidzwa mupfupi zvikuru, uye kunonoka kusina kunaka kunogona kutungamira mukukanzurwa kwakanyanya kwechikamu.simbasequencer inoita kuti kuenderana kwacho kuve kwakaruramaruzhasnguva yekuzvarwa pakati pehukurumutauriuye subwoofer, zvichibvumira ruzha rwebhendi rega rega remafrequency kusvika panzvimbo yekuteerera panguva imwe chete. Iyi ndiyo hwaro hwehunyanzvi hwekuwana mafrequency akaderera akajeka uye akapfava.

Sumo yeakangwaramusanganiswa weaudiokwakaita kuti manejimendi yemafirimu enzvimbo diki ave nyore kupfuura kare. Kugadziriswa kwema parameter akaomarara kwechinyakare kwakarerutswa kuita ma intuitive scene modes: "action blockbuster" mode inowedzera simba re transient low frequency, "music appreciation" mode inotarisa pakusimba uye hierarchy yema low frequency, uye "night mode" inochengetedza dynamic range yema low frequency uku ichideredza vhoriyamu yese. Vashandisi vanogona kuchinja zviri nyore kuburikidza ne intelligent interface, uyeprocessors Kuseri kwayo kuchagadzirisa otomatiki magadzirirwo chaiwo emaparamita akawanda.

Kuenderera mberikutarisayekuenzanisa maikorofoni inopa mukana wekugadzirisa mashandiro ehurongwa. Maikorofoni yekutarisa zvakatipoteredza yakagadzirirwa masisitimu emazuva ano ecinema inogona kutevera shanduko dzeacoustic mukamuri - kana fenicha yemukati ichifamba kana vashandi vachiwedzera kana kuderera, sisitimu inozozvigadzirisa yega.setihunhu hwesimba re subwoofer. Kuchinja kwekushisa nehunyoro pakumhanya kweruzha kuchabhadharwawo munguva chaiyo kuti kuve nechokwadi chekuti acoustic optimization inoshanda kwenguva refu.

Masisitimu eruzha ehunyanzvi emhando yepamusorozvinoratidza kukosha kwavo kukuru padanho rekupedzisira rekugadzirisa nzvimbo. Kana subwoofer yakabatana zvakakwana nemutauri mukuru, zvesenzvimbo yeruzhainopa kuenderana kunoshamisa - kungave kuri mafrequency akadzika akadzika akaputirwa nemaburi matema muInterstellar kana mafungu eruzha anodzvinyirira endege dzehondo dziri kunyura muDunkirk, dzinogona kudzokororwa nemazvo munzvimbo diki padanho remafirimu.maikorofoni isina wayaYakagadzirirwa musystem iyi haingoshandiswi chete pakudzora izwi zuva nezuva, asiwo inoita basa guru mukuongororwa kwezwi otomatiki: vashandisi vanongoda kubata maikorofoni isina waya voifambisa munzvimbo yekuteerera, uye system inogona kupedzisa otomatiki kuyerwa kwemapoinzi akawanda uye kugadzirisa nehungwaru maparamita ebhandi rega rega remafrequency. Kugadziriswa uku kwehunyanzvi "kunodzivirira manyepo" kunobvumira vatengiwo zvavo kuwana nyore nyore mhedzisiro yakakwana yakagadziriswa nenyanzvi dzeacoustic.

Muchidimbu, kugadziriswa kwemafirimu emazuva ano emunzvimbo diki kwakavandudzika kubva pakuva nemidziyo yakapfava kusvika pakuva nehurongwa hwesainzi hwakazara hunobatanidza zvinhu.odhiyo yehunyanzvi yemhando yepamusorohardware, manejimendi yesubwoofer yakangwara, chinotungamira ma amplifiers ehunyanzvi nemazvo, kushandurwa kwakanaka kwema amplifiers edhijitari, kugadziriswa kwe processor algorithm, kuwiriranisa kwakanyatsojeka kwesimbasequencers, uye kuyera kwakangwara kwemaikorofoni isina wayaIyi nzira yekugadzirisa nzvimbo haingogadzirisi chete miganhu yeacoustic yemakamuri madiki, asiwo inoisa mikana isingaperi yeacoustic munzvimbo shoma kuburikidza netekinoroji yehungwaru. Zvakakosha kutaura kuti maikorofoni isina waya iri musystem inoita kuti mashandiro ave nyore uku ichivimbisa hunyanzvi uye kururama kwekugadziriswa - vashandisi vanogona kuwana mhedzisiro yakagadziriswa kuburikidza nekuverenga kwakanyatsojeka nekushanda kuri nyore, vachiwana chiyero chakakwana pakati petekinoroji yehunyanzvi neruzivo rwemushandisi. Inobvumira mhuri yega yega kunzwa ruzha rwakawanda uye kunzwa kwakadzika kwakafanana nemasinema ehunyanzvi munzvimbo shoma, zvichipedzisa kusvetuka kwemhando kubva "kunonzwika" kusvika "kunoshamisa".
