Pakusintha malo ochitira zisudzo achinsinsi, kukonza kuyamwa kwa mawu ndi kuchepetsa phokoso ndikofunikira kwambiri. Chipinda chokonzedwa mwaukadaulo ndi chipinda chachizolowezi zimatha kukhala ndi zotsatira zosiyana kwambiri za mawu ndi zithunzi mkati ndi kunja. Nyumba nthawi zambiri zimagwiritsa ntchito konkire, mapanelo amatabwa kapena njerwa zolimba ngati zipangizo za pakhoma. Kunena zoona, zipangizozi zimatha kukwaniritsa zotsatira za kuyamwa kwa mawu, koma kuzama kwa zotsatira zake kumadalira kuchuluka kwa mamolekyu a zinthu zosiyanasiyana. Pa chipinda chowonera mawu chomwe chimayang'ana zotsatira za mawu, zinthu za pakhoma zokha sizokwanira kukwaniritsa zotsatira za kuyamwa kwa mawu. Kaya ndi nyumba yogona kapena nyumba yanyumba, malo ochitira zisudzo achinsinsi amafunikira kuyamwa kwa mawu kapena kutchinjiriza mawu. Kukonza mawu kumawongolera kuwonekera kwa mafunde a mawu mchipindamo, kusintha nthawi yozungulira mkati mwa chipindamo, potero kumawongolera mtundu wa mawu owonera makanema. Tiyeni tikambirane za zinthu zimenezo zokhudza kuyamwa kwa mawu ndi kutchinjiriza mawu lero.
Mayamwidwe amawu
Tanena mwachidule pamwambapa kuti zida zina zolimba zimatha kufooketsa mafunde amphamvu panthawi yofalitsa. Ndipotu, kuwonjezera pa kutengeka ndi zinthu zamkati, zipangizo zina zimatha kuwonetsanso phokoso la phokoso ndikulitumiza kumbali ina. Mayamwidwe amawu ndi kutsekereza mawu ndi njira ziwiri zosiyana zowongolera mawu. Mayamwidwe amawu amatanthawuza chodabwitsa cha kutha kwa mphamvu pambuyo poti mafunde amawu agunda pamwamba pa chinthu, ndipo kutchinjiriza kwa mawu kumatanthawuza njira yochepetsera phokoso munjira yofalitsa mawu. Mwachidule, kuyamwa kwa mawu kumachotsa mphamvu inayake ya mawu, ndipo kutsekereza mawu kumawongolera kufalikira kwa mafunde mbali ina ya khoma.
Mafunde akamayenda m’mlengalenga n’kugwira pamwamba pa zinthuzo, mbali ina yake imaonekera ndipo mbali ina imatengedwa. Zipangizo zamamvekedwe zomwe zimagwiritsidwa ntchito poyamwa mawu nthawi zambiri zimakhala ndi porous, ndipo zodziwika bwino ndi ulusi, tinthu tating'ono, ndi thovu. Phokosoli limachitika pa tinthu ting'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono timayambitsa mikangano ndi mamolekyu a mpweya ndi makoma opanda kanthu, motero amasintha mphamvu yamawu kukhala mphamvu ya kutentha kuti imveke bwino. Kuphatikiza pa zida zotulutsa mawu, palinso zida zomvekera bwino komanso zida zapadera zokomera mawu. Mayamwidwe amawu a resonance amaphatikizanso cholumikizira chimodzi, kachipangizo kakang'ono ka mayamwidwe amtundu wa resonance, kapangidwe kake ka filimu yopyapyala komanso kamvekedwe ka mawu. Mfundo yake ndikugwiritsanso ntchito mawonekedwe a zinthu ndi mpweya kuti apange dongosolo la resonant kuti akwaniritse zomveka bwino.
Choyezera kuyamwa kwa mawu, chomwe chimadziwikanso kuti mtengo wa NRC, chimatanthauzidwa ndi American Society for Testing and Materials (ASTM). Njira yowerengera ya NRC imatenga kuchuluka kwa chiwerengero cha mawu chomwe chimayamwa mawu pa ma frequency anayi a 250, 500, 1000 ndi 2000 Hz. Popeza kuchuluka kwa mawu omwe amayamwa mawu kumawonjezeka ndi kuchuluka kwa ma frequency, zimakhala zovuta kuti zinthu zomwe zimayamwa mawu zizitha kuyamwa mafunde ena otsika. Kawirikawiri, zinthu zomwe zimakhala ndi choyezera kuyamwa kwa mawu chochepera 0.2 zimatchedwa zinthu zowunikira, ndipo zinthu zomwe zili pamwamba pa 0.4 zitha kuonedwa ngati zinthu zomwe zimayamwa mawu. Ogula ayenera kusamala pogula zinthu zomwe zimakhala ndi choyezera kuyamwa kwa mawu chopitirira 1.0. Ngakhale kuti ndi zapamwamba kwambiri kuposa "mzere woyenera" wa 0.4, mitengo ya data yotereyi ndi yolakwika. American Society for Experimental Materials, yomwe imapanga mtengo wa NRC (choyezera kuyamwa kwa mawu), imagwiritsa ntchito nambala "0" kuyimira kuchuluka kwa mawu omwe amayamwa a chinthu chomwe sichingathe kuyamwa mphamvu iliyonse ya mawu. Mwa kuyankhula kwina, chinthuchi chimatha kuwonetsa mphamvu yonse ya mawu yomwe chimakumana nayo. Mosiyana ndi zimenezi, ngati chinthucho chimatenga mphamvu yonse ya mawu, chimawonetsedwa ndi nambala "1". Ndipotu, chinthu chilichonse chili ndi makhalidwe a kuwunikira ndi kuyamwa mphamvu ya mawu. "0" ndi "1" ndi malingaliro chabe. Chiwerengero chabwinobwino cha kuyamwa kwa mawu cha zinthu zomwe zimayamwa mawu chiyenera kukhala pakati pa 0 ndi 1. Mtengo. Chinthu chokhala ndi chiwerengero cha kuyamwa kwa mawu choposa 1.0 chimatanthauza kuti chimayamwa mphamvu zambiri za mawu kuposa zomwe chimayamwa, zomwe sizingatheke mwakuthupi. Ngati ogula akumana ndi mafotokozedwe otere, akhoza kukayikira mwachindunji kulondola kwa deta.
Kutseka mawu
Monga tanena kale, kutsekereza mawu komanso kuyamwa kwamawu ndi mitundu iwiri yosiyana yowongolera mawu. Mwanjira ina, mayamwidwe amawu amaganizira kwambiri mayamwidwe azinthu zomwezo, pomwe kutchinjiriza kwamawu kumaganiziranso kutayika kwa khoma logawanitsa komanso momwe mayamwidwe achipindacho pakutumizira mawu. Choncho, sizingakhale ngati phokoso lakuyamwitsa coefficient (NRC) lomwe limawerengedwa potengera kuchuluka kwa zikhalidwe, koma kufunikira kwa deta (kutayika kwa kufalikira kwa mawu ndi mawonekedwe afupipafupi a graph) ndi American Society for Testing and Materials kuti adziwe miyeso yofananiza zotsatira za gulu lofalitsa phokoso la khoma logawanitsa (STC). Ngakhale kuwerengera kumasiyanasiyana, kutayika kwa mawu kumasiyanasiyana malinga ndi pafupipafupi, ndipo khoma logawanitsa lomwe limagwiritsidwa ntchito powongolera kufalikira kwa mawu nthawi zambiri limawonjezeka pamene ma frequency akuwonjezeka.
Monga momwe mawu amatha kutengeka nthawi zonse kapena kuwonetseredwa ndi zinthu, amatha kudutsa khoma logawanitsa ndikutumiza mawu kumbali ina ya chipindacho. Mosiyana ndi mayamwidwe amawu, ngati malire amalire 0 akuyenera kukhala momwe phokoso silinawonekere, ndiye kuti malire ake otsutsana ndi 1 (pomwe phokoso lonse likuwonetsedwa kudzera pa khoma logawa) ndilotheka. Izi ndizotheka, mwachitsanzo, ngati tisiya zitseko ndi mazenera otseguka m'chipinda. M'chipinda chopanda chitetezo (mwachitsanzo, khoma logawaniza limodzi), kusiyana kulikonse pakutsegulira kungapangitse kuchepetsedwa kwa kutaya kwa kutulutsa mawu, zomwe ndikuganiza kuti nonse mumazidziwa kuchokera kunyumba kapena kuofesi yanu. Anthu ambiri angaganize kuti kuonjezera makulidwe a makoma ogawa kungapangitse kutayika kwa kufalikira kwa phokoso mozama, koma malinga ndi lamulo la khalidwe la kutchinjiriza phokoso, ngakhale mutawirikiza khoma la khoma, kuchuluka kwa phokoso kumangowonjezereka ndi 6dB.
Chifukwa chake, pama studio ojambulira, zisudzo zapadera, ndi madera ena omwe ali ndi zofunika kwambiri pakufalitsa mawu, mapangidwe a makoma ogawa kawiri ndi njira yodziwika bwino. Kumanga makoma a magawo awiri ndi chinthu chosavuta, mwachitsanzo, pakati pa makoma awiriwa mudzadzazidwa ndi zigawo zosiyana zakuthupi (monga zipangizo zogwiritsira ntchito mawu) kuti mukwaniritse bwino mawu otsekemera. Zosanjikiza zakuthupi ziyenera kuyikidwa mumlengalenga, kuti mafunde amvekedwe akhale kufalikira kwachiwiri. Kudzaza mwakhungu zigawo zakuthupi pakati pa makoma awiriwo sikungakwaniritse zotsatira zomwe mukufuna.
