Ukumuncwa somsindo: Umsindo ukumuncwa okuza. Sound ukumuncwa izinto: ithebula

Ezindaweni lapho ingxenye enkulu evele evulekile neziza isitini, stucco, zama-tile, ukhonkolo, ingilazi noma lwensimbi, njalo uzwe echo eside. Ephambi kwezinduna zakhiwo imithombo eminingana: zihambisane nezinsimbi zomculo, umsindo zezimboni, izingxoxo zabantu - umsindo ngqo kuthiwa esikhulu odongeni yakhe ukucabanga.

Lokhu kubandakanya ukwanda kwezithombe inkulumo futhi umsindo ezingeni egumbini. Ezimweni eziningi, lokhu nomphumela engathandeki. Ngokwesibonelo, amahholo zezindiza naseziteshini zezitimela, kanye nezitolo ezinkulu ezinkulu kanye kamasipala zenzelwe ngendlela efana ukunciphisa isikhathi reverberation (kungenjalo ibizwa ngokuthi reverberation isikhathi), njengoba kungenjalo akunakwenzeka ukuqonda okuqukethwe kwezikhangiso. Futhi phakathi komkhawulo ebekiwe kumele kube reverberation e yaseshashalazini, ekhonsathini kanye inkulumo amakamelo. reverberation Ukwandiswa kwesikhathi obuhlanekezela bezibona inkulumo kanye nomculo. Ngokuphambene, isikhathi esincane kuhilela "ezomile" Igumbi kanye nokuntuleka umsindo ukujula. Ukuze banciphise isikhathi reverberation noma izinguquko umhlobiso ingaphakathi ngokusebenzisa amamathiriyelii umsindo omnandi ezakhiwe.

Ukuvikela izakhiwo kusuka umsindo, isicelo ezihlukahlukene izinto labo abazokwazi ukudala isithiyo endleleni yakhe. Ukukhetha kwabo kunqunywa msebenzi. Inkinga angase afike futhi soundproofing kanye ukumuncwa umsindo. Mayelana nabo kanye nenkulumo.

soundproofing

Umgomo, nozobamba soundproofed - kukhombisa amagagasi umsindo, ukuze singathwesi awanike zingene ogangeni egumbini. Special soundproofing izinto nesakhiwo erects isithiyo endleleni kwamagagasi, okutshengisa kubo. Ikhono ukuklama ukwahlukanisa kuncike ngokuyinhloko ngesisindo. Luhlelo lolukhulu lwa kakhulu futhi kumzungezile izindonga umsindo nzima ukungena egumbini. Ukuze ukuhlola ikhono befaka izakhiwo for ukwahlukanisa umsindo kukhona value ezifana inkomba ukwahlukanisa umsindo. Lokhu ipharamitha ulinganiswa dB futhi kumelwe abe uhla 52-60 dB. Noise nangokuvikela izinto abhekwa obukhulu. Phakathi kwabo, okwakhiwa ngalo la mabhodi, isitini, ukhonkolo.

uzwakale iyavuleka

Injongo ukumuncwa umsindo - ukuncela umsindo, singavumeli kuye ukuze kubonakale ebusweni Abuyela endlini emuva kwezikhathi. It kukalwa nemingcele ezifana umsindo ukumuncwa izinto, ukushintsha kule uhla kusuka 0 kuya 1. Uma ukubaluleka kwalesi Coefficient ilingana no-zero, isiginali kubonakala off izindonga ewonke. Lapho wonke umsindo is egxile ngokuphelele, Coefficient ilingana indlela eya ebunyeni. Izinto ne izakhiwo olucutshungulwayo lilinganise abakholwako izinga elithile ukumuncwa umsindo. ukumuncwa Sound kufanele bube ngaphezu kuka-0.4.

Silencers kukhona amaqembu ezilandelayo:

• isakhiwo egqinsiwe;
• ivolumu;
• ukungena nakwamanye amazwe (kufaka fibrous);
• ukungena nakwamanye amazwe kanye khona zesikrini perforated;
• resonance.

Ayanda isilinganiso, ayanda ekilasini ukumuncwa.

wezinciphisi ukungena nakwamanye amazwe umsindo

ukukhiqiza wezinciphisi ukungena nakwamanye amazwe-uthayiphe ifomu izingqimba izinto ukungena nakwamanye amazwe engasindi, futhi kuvikelwe ngqo evele befaka noma ibanga ukusuka kubo. Lezi izinto akhiqizwa ngesisekelo kaolin, ilula, slag, vermiculite usebenzisa njengendlela yokuhlanganisa usimende, lime noma Gypsum. Lezi izinto kufanele amandla anele futhi ingasetshenziswa ukwehlisa umsindo elisendaweni yokwamukela abantu, emaphasishi esikoleni, imihubhe kanye ezitebhisini kwezakhiwo zikahulumeni kanye izakhiwo zezimboni.

wezinciphisi fibrous umsindo

Kulezi zindawo lapho wezinciphisi ukubukeka kufanele kube ngaphezulu aesthetically izinto osetshenziswayo ngamafayibha okuzenzela aphathwe ngendlela ekhethekile. Okuluhlaza ezazisetshenziselwa ukwenza yokukhiqiza yabo amaminerali uvolo, ingilazi uboya, kanye ukhuni nezindwangu zokwenziwa. wezinciphisi okunjalo umsindo isimo uphahla nodonga panel noma yezinhlobo ukuma curvilinear nevolumu. Phezu kobuso wezinciphisi ukungena nakwamanye amazwe isicelo inki ekhethekile elingase kudlule umoya, noma embozwe izinto ezikhethekile noma izindwangu, futhi ifa impahla breathability.

Ngo ukwakhiwa lanamuhla fibrous umsindo iyavuleka panel anegunya funa. Baye bahluleka kahle yabo ngokuya umsindo kanye nezimfuno okwandisa ukuthi ibekwe umhlobiso.

Nature ukumuncwa

Ukushabalalisa ka mandla ezidayiswayo ka kunyakaza acoustic e uhlobo fibre ne ukuvela ukushisa (uzwakale impahla eheha ingqondo) kunezimbangela eziningi. Okokuqala, ngenxa emoyeni viscosity, okuyinto eziqukethwe interstices interfiber ngokwanele, ukuguquguquka izinhlayiya emoyeni ivolumu engaphakathi mfutho ephelezelwa ukuhilizisana. Okwesibili, akukho okungenziwa emoyeni ngomshikisho imicu kokuba futhi eningi Imininingwane surface area. Ngaphezu kwalokho kukhona ngomshikisho ngokumelene nomunye endwangwini, bese amandla kwashabalala ngu ukuhilizisana phakathi Imicu yotshani crystal. Ngakho-ke, ngaleso naphakathi kanye amaza okusezingeni eliphezulu kwenzeka kahle ikakhulukazi umsindo ukumuncwa. kukhona Sound ukumuncwa impahla ngaphakathi 0.4 ... 1.0. Ngezinye imisindo ephansi kube nzima.

Qaphela ukuthi Coefficient ukumuncwa esibaliwe ratio ebusweni futhi hhayi ugxile amandla isignali ayihambi ngokusebenzisa yona amandla inani, okuyinto ethatha phezulu. Okuthathelwa kukho idatha ukunciphisa umsindo zokwakha eyisisekelo ithebula umsindo ukumuncwa okuza. It is kukhonjisiwe ngezansi.

Ithebula. ukumuncwa kahle, ukumuncwa okuza

isakhiwo nomsindo-eheha ingqondo

izinto Sound-iyavuleka kukhona fibrous kanye nohlobo ukungena nakwamanye amazwe ngokuvamile iningi esetshenziswa ukuthuthukisa izakhiwo acoustic kwezakhiwo yeshashalazi, zokubukela amabhayisikobho, concert amahholo futhi ukuqopha studios. Asetshenziswa ukwenza umsindo omncane e izinkulisa, izibhedlela, izikole.

Ukuze kwandiswe ukunciphisa umsindo imisindo ephansi, ukushuba noma izinto we okuhleliwe emoyeni igebe phakathi mfutho futhi isakhiwo sibonakalisa kumele lenyuke.

Uma wezinciphisi fibrous kungukuthi isicelo kwi upende futhi abanalwazi lokuthi umzimba usebenza olwelwesini Indwangu, angasetshenziswa nge yokuvikela ekulimaleni yezinto ezibonakalayo perforated.

Ngo igebe phakathi kwesikrini futhi indaba of the fibre ibekwe ngendwangu esiwuhogelayo ukugwema umoya engene izinhlayiya fibrous. Sound-iyavuleka isakhiwo, ifakwe ikhava perforated, enze kube nokwenzeka ukuba athole okuhle umsindo izinga ukunciphisa nhlobo amaza. Ukulungisa imvamisa isici ukumuncwa kwenzeka ngokusebenzisa ukukhethwa izinto. Kanye obuhlukahlukene Uhlonze lwalo, isayizi shape, ibanga phakathi izimbobo. Umsindo isakhiwo esiningi, ifakwe screen perforated metal, it is kabanzi njengendlela ikhava ocekela phansi-ubufakazi. Omunye izinto ezinjalo namuhla "Eco Shumanet".

The best izinto umsindo abaningi. fiberglass

Izinto ezenziwe ngesisekelo ingilazi Imicu yotshani kokuba amandla okusezingeni eliphezulu futhi kuyaqina. Glass uvolo futhi ihlinzeka vibration okusezingeni eliphezulu. Sound ukumuncwa Vitreous ngenxa yokubakhona ezikhaleni phakathi Imicu inqwaba imigodi egcwele umoya. Izinzuzo ingilazi uboya ukuphepha umlilo, isisindo ekukhanyeni, kuyaqina okusezingeni eliphezulu, akukho ukumuncwa amanzi, umhwamuko permeability, amakhemikhali passivity. Glass uvolo njengoba-elementi lumangaza acoustic yezincwadi noma amapuleti, njengoba omunye Izendlalelo multilayer umsindo iyavuleka izakhiwo.

amaminerali uvolo

Mineral uvolo sisetshenziselwa izinto lunemicu okuyizinto izinto zokusetshenziswa for the silicate liyancibilika amatshe, steel slag, futhi Izingxube yalo.

Pluses impahla: incombustibility, amakhemikhali sokungasebenzi, futhi ngenxa yalokho, ukungabi bikho kokukhanya ukugqwala ku insimbi contact ngensontfo amaminerali. Ikhwalithi ukumuncwa umsindo yaqaphela ngenxa yelungiselelo kunezinxushunxushu imicu.

Ukuze uthole okusezingeni eliphezulu umsindo ukumuncwa Coefficient (0.7 kuya 0.9) kulo lonke Ibhendi yokuvama esetshenziswa multilayer isakhiwo uhlobo resonant, okuyinto aqukethe zesikrini eziningana parallel kokuba perforations ezahlukene emoyeni izikhala of ukushuba ezahlukene.

Izinto "Shumanet Eco"

Mela ungqimba acoustic okumele zisetshenziswe Uhlaka ngodonga, asezindongeni amaphepha plasterboard nofana izakhiwo kokufulela okwesikhashana. Zenziwa ngesimo zezinhlangothi hydrophobized ingilazi endwangwini, okuyinto laminated nge glass. Indaba isicelo is isibopho inert esekelwe acrylic, okwenza umsindo iyavuleka panel nonflammable.

Izici umthamo omkhulu isikhala

Kufanele kuqashelwe ukuthi ezindaweni ukuthi babe ivolumu ephezulu, umphumela ukunciphisa izikhathi reverberation ngenxa yokwakhiwa ezengeziwe umsindo ukumuncwa akuyona omkhulu kangaka. Lezi zakhiwo alawule reverberation sikhathi ngenxa ifomu kokufulela nezindonga. Ngokwesibonelo, ukusetshenziswa kokufulela non-flat futhi oyindilinga kanye pilasters bobunjwa noma balcony ahlukahlukene ezindongeni kwenza omkhulu umsindo ukumuncwa. Le ndlela yokuxhumana yezakhiwo kwenza kube nokwenzeka ukuba athole diffuseness inkambu acoustic ngaphezulu, okuyinto kunomphumela omuhle sezulu acoustic zasendlini.

Kufanele kuqashelwe ukuthi le Imininingwane umsindo wokwehla ihholo luyanda khona imihlobiso, izihlalo lula, amakhethini. Kumele kunakwe lapho ukhetha izinto kokuqeda, ukuze sithathe ukumuncwa umsindo. ukumuncwa Sound kulokhu kuyokhula.
