Ekwenzeni ngokwezifiso amathiyetha azimele, ukucutshungulwa kokumuncwa komsindo nokunciphisa umsindo kuyingxenye ebalulekile. Igumbi eliphathwe ngobuchwepheshe nge-audiyo kanye negumbi elivamile lingaveza imiphumela ehlukene kakhulu yokuzwakalisa umsindo ngaphakathi nangaphandle. Izakhiwo ngokuvamile zisebenzisa ukhonkolo, amaphaneli ezinkuni noma izitini eziqinile njengezinto zodonga. Empeleni, lezi zinto zingafeza umphumela wokuvalela umsindo, kodwa ukujula komphumela kuncike ekujuleni kwama-molecule wezinto ezahlukene. Egumbini elivalela umsindo elilandela imiphumela yomsindo, izinto zodonga zodwa azanele ukufeza umphumela wokuvalela umsindo. Kungakhathaliseki ukuthi yi-villa noma isakhiwo sefulethi, amathiyetha azimele azimele adinga ukumuncwa komsindo noma ukuvalela umsindo. Ukwelashwa kwe-acoustic kulawula ukubonakaliswa kwamagagasi omsindo ekamelweni, kulungisa isikhathi sokuzwakala ngaphakathi kwegumbi, ngaleyo ndlela kuthuthukiswe ikhwalithi yomsindo yokubuka ama-movie. Ake sixoxe ngalezo zinto mayelana nokumuncwa komsindo nokuvala umsindo namuhla.
Ukumuncwa komsindo
Sikhulume kafushane ngenhla ukuthi ezinye izinto eziqinile zinganciphisa i-coefficient yamaza omsindo ngesikhathi senqubo yokusabalala. Eqinisweni, ngaphezu kokumuncwa yizinto zangaphakathi, ezinye izinto zingabonakalisa futhi igagasi lomsindo futhi zilidlulisele kolunye uhlangothi. Ukumuncwa komsindo kanye nokuvimbela umsindo kuyizindlela ezimbili ezihlukene ngokuphelele zokulawula umsindo. Ukumuncwa komsindo kubhekisela esimweni sokulahlekelwa amandla ngemva kokuba amaza omsindo eshaye ubuso bento, kanti ukumuncwa komsindo kubhekisela endleleni yokunciphisa umsindo endleleni yokusabalala kwamaza omsindo. Kalula nje, ukumuncwa komsindo kususa inani elithile lamandla omsindo, kanti ukumuncwa komsindo kulawula ukudluliswa kwamaza omsindo kolunye uhlangothi lodonga.
Uma amaza omsindo ehamba emoyeni futhi ethinta ubuso bezinto ezimunca umsindo, ingxenye yawo izobonakala bese ingxenye izomuncwa. Izinto ze-acoustic ezisetshenziselwa ukumunca umsindo ngokuvamile zinezakhiwo ezinezimbobo, kanti ezivamile yizintambo, izinhlayiya, namagwebu. Igagasi lomsindo liyisigameko ezindaweni ezingenakubalwa ezincane ngaphakathi kwezinto, lapho libangela khona ukungqubuzana nama-molecule omoya kanye nezindonga ezingenazo, ngaleyo ndlela liguqula amandla omsindo abe amandla okushisa ukuze kufezwe umphumela wokumunca umsindo. Ngaphezu kwezinto ezimunca umsindo ezinezimbobo, kunezakhiwo ezimunca umsindo ezinezimbobo kanye nezakhiwo ezikhethekile ezimunca umsindo. Ukumunca umsindo we-resonance kufaka phakathi i-resonator eyodwa, indlela yokumunca umsindo we-resonance plate enezimbobo, isakhiwo semininingwane ye-resonance yefilimu encane kanye nesakhiwo sokumunca umsindo we-resonance plate encane. Isimiso salo futhi ukusebenzisa isakhiwo sezinto nomoya ukwakha uhlelo lwe-resonant ukuze kufezwe ukumunca umsindo.
I-coefficient yokumunca umsindo, eyaziwa nangokuthi inani le-NRC, ichazwa yi-American Society for Testing and Materials (ASTM). Indlela yokubala yezinombolo ye-NRC ithatha inani eliphakathi le-arithmetic le-coefficient yokumunca umsindo wezinto ezibonakalayo kuma-frequency amane angu-250, 500, 1000 kanye no-2000 Hz. Njengoba i-coefficient yokumunca umsindo wezinto ezimunca umsindo ikhula ngokwanda kwemvamisa, kunzima ngezinto ezimunca umsindo ezijwayelekile ukumunca amaza omsindo aphansi. Ngokuvamile, imikhiqizo ene-coefficient yokumunca umsindo engaphansi kuka-0.2 ibizwa ngokuthi izinto ezibonisa ukukhanya, kanti izinto eziphakeme kuno-0.4 zingabhekwa njengezinto ezimunca umsindo. Abathengi kudingeka baqaphele lapho bethenga izinto ezinomsindo ezine-coefficient yokumunca umsindo edlula u-1.0. Nakuba iphakeme kakhulu kune-"line qualified" ka-0.4, amanani anjalo edatha awalungile. I-American Society for Experimental Materials, eyakha inani le-NRC (coefficient yokumunca umsindo), isebenzisa inombolo ethi "0" ukumela i-coefficient yokumunca umsindo wezinto ezingakwazi ukumunca noma yimaphi amandla omsindo angenzeka. Ngamanye amazwi, le nto ingabonakalisa wonke amandla omsindo ehlangana nawo. Ngokuphambene nalokho, uma into imunca wonke amandla omsindo, iboniswa yinombolo "1". Eqinisweni, noma iyiphi into inezici zokubonakalisa nokumunca amandla omsindo. U-"0" no-"1" kumane nje kuyizindinganiso zokubhekisela zomkhawulo wethiyori. I-coefficient evamile yokumunca umsindo yezinto ezimunca umsindo kufanele ibe phakathi kwenani lika-0 no-1. Izinto ezine-coefficient yokumunca umsindo engaphezu kuka-1.0 zisho ukuthi imunca amandla omsindo amaningi kunalokho ekubonakalisayo, okuyinto engenakwenzeka ngokomzimba. Uma abathengi behlangana nezincazelo ezinjalo, bangabaza ngqo ukunemba kwedatha.
Ukuvimbela umsindo
Njengoba kushiwo ngaphambili, ukuvala umsindo kanye nokumuncwa komsindo kuyizinhlobo ezimbili ezahlukene zokulawula umsindo. Ngomqondo othile, ukumuncwa komsindo kubheka kakhulu i-coefficient yokumuncwa kwezinto ngokwazo, kuyilapho ukuvala umsindo kubheka kokubili ukulahlekelwa kokudluliselwa kodonga lokuhlukanisa kanye nezici zokumuncwa kwegumbi ngesikhathi sokudlulisa umsindo. Ngakho-ke, akunakufana ne-coefficient yokumuncwa komsindo (i-NRC) ebalwa ngokuthatha isilinganiso samanani, kodwa idinga idatha (ukulahlekelwa kokudluliselwa komsindo kanye nezici zemvamisa yegrafu) kanye ne-American Society for Testing and Materials ukunquma amazinga okuqhathanisa amanani atholakele ekilasini lokudlulisa umsindo lodonga lokuhlukanisa (i-STC). Nakuba izibalo ziyahlukahluka, ukulahlekelwa kokudluliselwa komsindo kuyahlukahluka ngokuya ngemvamisa, futhi udonga lokuhlukanisa olusetshenziswa ukulawula ukusabalala komsindo luzokhula ngokuvamile njengoba imvamisa ikhula.
Njengoba nje umsindo ungahlala umuncwa noma uboniswa yinto ethile, ungahlala udlula odongeni lokuhlukanisa futhi udlulisele umsindo kolunye uhlangothi lwegumbi. Ngokungafani nokumuncwa komsindo, uma inani lomkhawulo wokubhekisela elingu-0 lihloselwe ukuba yikho lapho umsindo ungakaphonswa khona, khona-ke inani lawo lomkhawulo eliphambene 1 (lapho wonke umsindo uphonswa khona odongeni lokuhlukanisa) lingenzeka. Lokhu kungenzeka, isibonelo, uma sishiya iminyango namafasitela evulekile ekamelweni. Ekamelweni elingavikelwe (okungukuthi, udonga lokuhlukanisa olunesendlalelo esisodwa), noma yiliphi igebe ekuvulekeni kungabangela ukwehla kokulahlekelwa kokudluliselwa komsindo, engicabanga ukuthi nonke niyazi ekhaya noma ehhovisi. Abantu abaningi bangase bacabange ukuthi ukwandisa ubukhulu bezindonga zokuhlukanisa kungandisa ukulahleka kokudluliselwa komsindo ngokujulile, kodwa ngokomthetho wekhwalithi yokufakwa komsindo, noma ngabe uphinda kabili ubukhulu bodonga, inani lokufakwa komsindo linganda kuphela ngo-6dB.
Ngakho-ke, kuma-studio okuqopha, amathiyetha azimele, kanye nezinye izindawo ezinezidingo eziphezulu zokudlulisa umsindo, ukwakheka kwezindonga ezihlukanisa kabili kuyindlela evame kakhulu. Ukwakhiwa kwezindonga ezihlukanisa kabili nakho kuyindaba ebucayi, isibonelo, phakathi kwezindonga ezimbili kuzogcwaliswa izendlalelo zezinto ezahlukene (njengezinto ezimunca umsindo) ukuze kufezwe ukuvikela umsindo okungcono. Isendlalelo sezinto kumele sibekwe engqimbeni yomoya, ukuze amaza omsindo abe ukusabalala kwesibili. Ukugcwalisa ngokungazi izingqimba zezinto phakathi kwezindonga ezimbili ngeke kufeze umphumela wokuvikela umsindo ofiselekayo.
