Mhlawumbe ukubhonga kwesitimela esidala esidlula ku-movie kungavusa kalula izinkumbulo zethu zobuntwana, njengokungathi sixoxa indaba yesikhathi esedlule.
Kodwa uma lolu hlobo lomsindo lungekho kumamuvi, kodwa luvame ukuvela eduze kwekhaya lethu, mhlawumbe le "nkumbulo yobungane" iphenduka izinkinga ezingapheli ngokuphazima kweso. Lo msindo ongajabulisi uwumsindo.
Umsindo awuphazamisi amaphupho abantu nje kuphela, kodwa okubaluleke kakhulu, indawo enomsindo yesikhathi eside ingabangela umonakalo ongenakulungiseka ku-physiology yabantu kanye nokusebenza kwengqondo, futhi ingenye yemithombo ebaluleke kakhulu yokungcola endaweni yesimanje.
Ukuncishiswa komsindo kanye nokuvala umsindo sekuphenduke isidingo esiphuthumayo sabantu.
Ngokuvamile, izici ezithinta izinga lomsindo ngokuyinhloko zihlanganisa ivolumu yomthombo womsindo kanye nebanga phakathi kwefrikhwensi yomsindo nomthombo womsindo.
Esimweni lapho ivolumu, imvamisa yomsindo kanye nebanga phakathi komthombo womsindo nomuntu akuguquki kalula, ngokuqinisa umgoqo womsindo ongokomzimba - ukusebenza komsindo wokuvala iminyango namafasitela, ukudluliswa komsindo kuvinjelwe ngangokunokwenzeka, ngaleyo ndlela. ukudala ejabulisayo futhi ntofontofo imvelo.
Umsindo awukhululekile ngokomzimba noma ngokwengqondo, awujabulisi, awukhululekile, awufunwa, noma uyacasula, umsindo ongamukelekile kulabo abawuzwayo, othinta ingxoxo noma ukucabanga kwabantu, umsebenzi, ukutadisha, nokuphumula umsindo.
Ibanga lemvamisa yokuzwa kwendlebe yomuntu yomsindo licishe libe ngu-20Hz~20kHz, futhi ububanzi obuphakathi kuka-2kHz no-5kHz buyindawo ezwela kakhulu endlebeni yomuntu. Amaza omsindo aphansi kakhulu futhi aphezulu kakhulu angabangela ukungakhululeki.
Ibanga levolumu elinethezeke kakhulu lingu-0-40dB. Ngakho-ke, ukulawula indawo yethu yokuhlala nokusebenza kwe-acoustic kule ndawo kungathuthukisa ukunethezeka ngokuqondile nangokonga.
Umsindo we-low-frequency isho umsindo one-frequency engu-20~500Hz, i-500Hz~2kHz iyi-intermediate frequency, futhi i-high frequency ngu-2kHz~20kHz.
Empilweni yansuku zonke, ama-compressor air-conditioning, izitimela, izindiza, izinjini zezimoto (ikakhulukazi eduze kwemigwaqo nama-viaducts), imikhumbi, amakheshi, imishini yokuwasha, iziqandisi, njll. ngokuvamile imisindo ephansi, kuyilapho izimpondo kanye nekhwela lemoto. , izinsimbi zomculo, ukudansa kwesikwele, ukukhonkotha kwenja, ukusakazwa kwesikole, izinkulumo, njll. ngokuvamile imisindo ephezulu.
Umsindo we-low-frequency unebanga elide lokudlulisela, amandla okungena aqinile, futhi awushintshi kakhulu ngebanga, okuyingozi kakhulu kumzimba womuntu.
Umsindo we-high-frequency unokungena okungalungile, futhi uzoncishiswa kakhulu njengoba ibanga lokusabalalisa likhuphuka noma uhlangabezana nezithiyo (isibonelo, ekukhuphukeni ngakunye kwamamitha ayi-10 ebangeni lokusabalalisa lomsindo we-high-frequency, umsindo uzoncishiswa ngo-6dB).
Ivolumu iyona enembile kakhulu ukuzwakala. Ivolumu ikalwa ngama-decibel (dB), futhi ivolumu ye-ambient engaphansi kuka-40dB iyindawo enethezekile kakhulu.
Futhi umthamo ongaphezu kuka-60dB, abantu bangazizwa bengakhululekile.
Uma ivolumu idlula ku-120dB, kuthatha iminithi elingu-1 kuphela ukudala ukungezwa kwesikhashana endlebeni yomuntu.
Ngaphezu kwalokho, ibanga eliphakathi komthombo womsindo nomuntu nalo lithinta ngokuqondile umbono womuntu womsindo. Lapho ibanga liqhubeka, ivolumu iyancipha.
Kodwa-ke, ngomsindo we-low-frequency, umthelela webanga ekwehlisweni komsindo awubonakali.
Uma kungenakwenzeka ukwenza izinguquko eziningi kakhulu endaweni yenhloso, kungase kube ukukhetha okuhlakaniphile ukushintshela emnyango wekhwalithi ephezulu kanye nefasitela, futhi uzinikeze ikhaya elinokuthula nelihle.
Isethi enhle yezicabha namafasitela inganciphisa umsindo wangaphandle ngaphezu kuka-30dB. Ngokucushwa kokuhlanganiswa kochwepheshe, umsindo ungancishiswa nakakhulu.
Ingilazi iyisakhi esibaluleke kakhulu esithinta ukufakwa komsindo kweminyango namafasitela. Ezinhlotsheni ezahlukene zomsindo, ukulungisa ingilazi ehlukene kuwukukhetha okuchwepheshile nokongayo.
High frequency umsindo - insulating glass
Insulating glass iyinhlanganisela 2 noma ngaphezulu izingcezu engilazi. Igesi ekungqimba oluphakathi nendawo engenalutho ingakwazi ukumunca amandla okudlidliza komsindo okuvama okuphakathi nendawo naphezulu, ngaleyo ndlela yehlise ukuqina kwegagasi lomsindo.Umphumela wokuvala umsindo wengilazi evikelayo uhlobene nogqinsi lwengilazi, igesi yongqimba olungenalutho kanye nenombolo nogqinsi lwesendlalelo se-spacer.
Ezimweni eziningi, ingilazi ye-insulating inomphumela omuhle kakhulu wokuvinjwa kumsindo omkhulu ophakathi nendawo kanye nokuphakama okuphezulu. Futhi njalo lapho ubukhulu bengilazi buphindwe kabili, umsindo ungancishiswa ngo-4.5~6dB.
Ngakho-ke, ukushuba okukhulu kwengilazi, kuqina ukuvala umsindo.
Singathuthukisa umphumela wokuvala umsindo wezicabha namafasitela ngokwandisa ukushuba kwengilazi evikelayo, ukugcwalisa igesi engasebenzi, nokwandisa ukujiya kongqimba olungenalutho.
Umsindo wefrikhwensi ephansi -i-insulatingingilazi laminated
Ngaphansi kobukhulu obufanayo, ingilazi ye-laminated inomthelela omkhulu ekuvimbeni amaza omsindo aphakathi nendawo naphansi, okungcono kunengilazi yokuvikela.
Ifilimu ephakathi kwengilazi elayiniwe ilingana nongqimba olumanzi, futhi isendlalelo sokunamathisela se-PVB sisetshenziselwa ukumunca amaza omsindo aphakathi nendawo naphansi futhi kucindezele ukudlidliza kwengilazi, ukuze kuzuzwe umphumela wokuvala umsindo.
Kuyaphawuleka ukuthi ukusebenza kwe-insulation sound of the interlayer kungathinteka ngokushisa.
Ebusika obubandayo, i-interlayer izolahlekelwa okunye ukunwebeka kwayo ngenxa yokushisa okuphansi futhi inciphise umphumela wokukhipha umsindo. Ingilazi ye-laminated engenalutho, ehlanganisa izinzuzo zakho kokubili ingilazi engenalutho kanye nengilazi elayishiwe, ingachazwa njengengilazi "yonke" engazwakali.
Ukwakhiwa Okuvaliwe - Ibanga Lezimoto Lokuvikela umsindo
Ngaphezu kokuthembela engilazini, ukufakwa kahle komsindo nakho kuhlobene eduze nesakhiwo sokubeka uphawu.
I-MEDO isebenzisa izinhlobo ezahlukene ze-EPDM ze-automotive-grade sealing materials ezifana ne-soft and hard co-extrusion, igwebu eligcwele, njll., ezinokuqina okuhle kakhulu futhi ezinganciphisa ngempumelelo ukwethulwa komsindo. Idizayini yesakhiwo esinamashaneli amaningi sokuvala isikhala, kanye nengilazi, kuyahambisana ukuze kwakhiwe umgoqo womsindo.
indlela evulekile
Nakuba kunezindlela ezihlukahlukene zokuvula iminyango namafasitela wesistimu, idatha yokuhlola ibonisa ukuthi indlela yokuvula yokuvula i-casement ingcono kunokuslayida ngokwemibandela yokumelana nokucindezela komoya, ukuvala uphawu kanye nokuvala umsindo.
Ngokwesisekelo sezidingo ezibanzi, uma ufuna ukufakwa komsindo okungcono, iminyango yamafasitela namafasitela ayakhethwa.
Ngaphezu kwalokho, i-phenduka amawindifuthi amafasitela isisitho selanga endlini kungenziwa ibhekwe njengendlela isicelo izindlela ezikhethekile of iminyango namafasitela, okuyinto babe izinzuzo amafasitela casement futhi babe izinzuzo zabo ezikhethekile, ezifana amafasitela enyakazayo turn ephephile futhi mnene kakhudlwana komoya.
I-MEDO, ethatha uchwepheshe wezixazululo zesistimu njengomthwalo wayo wemfanelo, isiqongelele cishe iminyaka engu-30 yokuqongelela ubuchwepheshe, ithembele kusisekelo somkhiqizo ocebile nophelele we-matrix, ihumusha indawo yohlelo lokusebenza kanye nezidingo zamakhasimende olimini lokuklama, futhi isebenzisa ubuchwepheshe nobuqinile. isimo sengqondo sesayensi sokuma kwabangcono kakhulu kubasebenzisi, thola umbono wokuhlinzeka ngesixazululo esiphelele sephrojekthi ngayinye ngokucabanga okuhlelekile kanye nomklamo ophambili.
