Sound mayamwidwe: Sound koefishienti mayamwidwe. zipangizo Sound mayamwidwe: tebulo

Kumadera kumene chiwerengero chachikulu cha kali kotsegula akupanga njerwa, stucco, matailosi, konkire, galasi kapena zitsulo, nthawizonse kumva Echo yaitali. Pamaso pa malo mabuku angapo: limodzi nyimbo, mafakitale phokoso, zolankhula za anthu - phokoso mwachindunji ndi superimposed pa khoma mawunikidwe wake.

Iyi imalimbikitsa ponso kulankhula chiwerewere ndi mlingo phokoso mu chipinda. Mu zochitika ambiri, amenewa ndi osafunika. Mwachitsanzo, maholo a ndege ndi sitima, komanso amagulako zazikulu ndi okwerera sitima tinapangidwa mu njira monga kuchepetsa reverberation nthawi (mwinamwake iwo akutchedwa reverberation nthawi), chifukwa mukatero ndi sangathe kumvetsa zomwe zili malonda. Komanso Malire Kwalamulidwa ayenera kukhala reverberation mu zisudzo, konsati ndi nkhani zipinda. Kuchuluka reverberation nthawi kupotoza maganizo mawu komanso nyimbo. Koma nthawi yaing'ono kumatanthauza "youma" chipinda ndi kupanda akuya phokoso. Kuchepetsa reverberation nthawi kapena kusintha chokongoletsera mkati ntchito phokoso kungolandira zipangizo ndi zomangamanga.

Pofuna kuteteza malo kwa phokoso, ntchito zosiyanasiyana zipangizo kuti angathe kulenga chopinga mu njira yake. Kusankha kwawo anatsimikiza ndi ntchitoyo. vuto adzabwera ndi soundproofing ndi mayamwidwe phokoso. Za iwo ndi kukayankhula.

soundproofing

The cholinga, moyang'anana soundproofed - kuonetseredwa kwa mafunde phokoso, kuti awapatse kudutsa khoma la chipinda. Special soundproofing zipangizo dongosolo erects chotchinga pa njira ya mafunde, kumene kumasonyeza iwo. Kukwanitsa kupanga kutchinjiriza zimatengera makamaka mwa kulemera. Chachikulu ndi wakuda ndi makoma, phokoso kovuta kudutsa mu chipinda. Kuwunika luso kamodzi nyumba kwa kutchinjiriza phokoso ndi mtengo monga index wa kutchinjiriza phokoso. chizindikiro ichi amayezedwa DB ndi ayenera kukhala mu osiyanasiyana 52-60 DB. Phokoso chimateteza zipangizo amaonedwa kukhala wandiweyani. Pakati pawo, drywall, njerwa, konkire.

kuwomba kungolandira

Cholinga cha mayamwidwe phokoso - kuyamwa phokoso, osati polola kuti anasonyeza pamwamba kumbuyo mu chipinda. Iwo chimaonekera mwa magawo monga zipangizo phokoso mayamwidwe, kusintha mu osiyanasiyana kuchokera 0 kuti 1. Ngati mtengo wa koyefishienti ichi ndi wofanana ndi ziro, mbendera zimaonekera pa makoma onsewo. Pamene phokoso lonse odzipereka kwathunthu, ndi koyefishienti ndi wofanana ndi umodzi. Zipangizo ndi katundu pansi kulingalira Udindo amene ali ndi mlingo wina wa mayamwidwe phokoso. Sound mayamwidwe iwo ayenera kukhala oposa 0.4.

Silencers ndi magulu otsatirawa:

• magawo dongosolo;
• buku;
• porous (kuphatikizapo fibrous);
• porous ndi pamaso pa zowonetsera perforated;
• kumveka bwino.

The apamwamba chiŵerengero, ndi apamwamba a kalasi mayamwidwe.

porous phokoso absorbers

kutulutsa absorbers porous-mtundu mwa mawonekedwe a mbale zipangizo porous opepuka, ndi wotetezedwa mwachindunji kali kamodzi kapena patali iwo. zinthuzi amapangidwa pa maziko wa kaolin, pumice, slag, vermiculite ntchito monga binder simenti, laimu kapena gypsum. zinthuzi ndi mphamvu zokwanira ndipo angagwiritsidwe ntchito kuchepetsa phokoso modutsa, hallways, makonde ndi stairways nyumba onse ndi nyumba mafakitale.

fibrous phokoso absorbers

M'madera amene maonekedwe absorbers akhale azisangalala kwambiri zipangizo Ntchito ndi ulusi ankachitira mu njira yapadera. The zopangira ntchito kupanga awo mchere ubweya wa nkhosa galasi, komanso mitengo ndi ulusi kupanga. Chotero phokoso absorbers ndi mawonekedwe a denga ndi khoma mapanelo kapena zinthu za mawonekedwe curvilinear ndi buku. Padziko absorbers porous ntchito inki wapadera kuti adutse mpweya, kapena iwo ataphimbidwa ndi zipangizo zapadera kapena nsalu, komanso adzatenga chuma cha breathability.

Pomanga zamakono fibrous phokoso kungolandira mapanelo ambiri zikufunika kwambiri. Iwo atsimikizira Mwachangu awo mawu a zowulutsira kukakumana ndi zofuna kuwonjezeka kuti anayikidwa pa yokongola.

Nature mayamwidwe

Madyaidya ndikuledzera wa absorbers mphamvu ya Phokoso lamayimbidwe mu mtundu CHIKWANGWANI ndi zamoyo wa kutentha (kuomba zinthu zogwira) ali zimayambitsa angapo. Choyamba, chifukwa mpweya kukhuthala, amene ali interstices interfiber zokwanira, fluctuation ndi tinthu mpweya mu buku lamkati la absorber limodzi ndi kukhululukirana. Chachiwiri, pali mpweya mikangano ulusi kukhala komanso yokulirapo okwana padziko dera. Komanso pali mikangano ndi ulusi wina ndi mzake, ndi mphamvu ankakhala moyo wotayirira ndi mikangano pakati pa ulusi mibulu. Choncho, pa sing'anga ndi mafurikwense mkulu kumachitika makamaka imayenera phokoso mayamwidwe. Sound mayamwidwe zakuthupi mwa 0.4 ... 1.0. Pa mafurikwense otsika kupanga usagwiritse.

Onani kuti mayamwidwe koyefishienti kuchita masamu kuti chiŵerengero cha pamwamba ndipo si atamezedwa mphamvu ya chizindikiro kudzera ku mphamvu yonse, amene amachita padziko. Kwa deta Buku pa kuchepetsa phokoso zipangizo maziko ndi gome la koefishienti phokoso mayamwidwe. Iwo pansipa.

Kapangidwe phokoso-zogwira

Sound-kungolandira zipangizo ali fibrous ndi mtundu porous nthawi zambiri ntchito pokonzanso lamayimbidwe katundu ochitira masewero malo, cinemas, maholo konsati ndi kujambula situdiyo. Iwo amagwiritsa ntchito zochepa phokoso mu kindergartens, zipatala, sukulu.

Kuonjezera kuchepetsa phokoso pa mafurikwense otsika, ndi makulidwe kapena zipangizo za inakonzedwa mpweya kusiyana pakati pa absorber ndi dongosolo kuwalitsa ayenera ziwonjezeke.

Ngati absorbers fibrous si ntchito pa utoto ndi iwo alibe wosanjikiza kunja kwa nsalu, iwo akhoza kugwiritsidwa ntchito ndi chitetezo zisaonongeke ndi chuma perforated.

Mu kusiyana pakati pa nsalu yotchinga ndi chuma CHIKWANGWANI aikidwa chinsalu breathable kupewa mpweya kulowa particles fibrous. Sound-kungolandira dongosolo, zida ndi chivundikiro perforated, n'zotheka kupeza bwino kuchepetsa khalidwe phokoso pa mafurikwense onse. Kusintha pafupipafupi khalidwe mayamwidwe kumachitika mwa kusankha zipangizo. Komanso osiyanasiyana wochindikala, kukula ndi mawonekedwe, mtunda wa pakati mabowo ndi. Kumveka dongosolo mtima, okonzeka ndi chophimba perforated zitsulo, izo chimagwiritsidwa ntchito ngati chophimbira vandal-umboni. Mmodzi wa lero zomangira ndi "Eco Shumanet".

The bwino phokoso-kungolandira zipangizo. fiberglass

Chuma pamaziko a ulusi galasi ndi mphamvu yapamwamba ndi elasticity. Galasi ubweya komanso amapereka kugwedera mkulu. Sound mayamwidwe vitreous chifukwa kukhalapo mu mipata pakati pa ulusi ambiri voids wodzazidwa ndi mpweya. Ubwino wa nkhosa galasi ndi chitetezo moto, kulemera kuwala, elasticity mkulu, palibe mayamwidwe madzi, nthunzi ya madzi permeability, mankhwala passivity. Galasi ubweya monga mchitidwe wa kakasi lamayimbidwe wa masikono kapena mbale, monga mmodzi wa zigawo za multilayer phokoso kungolandira nyumba.

ubweya mchere

Maminolo ubweya ndi chuma fibrous, amene zipangizo kwa silicate chimasungunula miyala, zitsulo slag, ndi zosakaniza zace.

Pluses zakuthupi: incombustibility, mankhwala chilichonse, ndipo chotero, pakalibe dzimbiri pa zitsulo pokhudzana ndi ubweya mchere. Ubwino wa mayamwidwe phokoso kuzindikira chifukwa dongosolo wachisokonezo ulusi.

Kuti mupeze mkulu phokoso mayamwidwe koyefishienti (0,7 kwa 0.9) mu pafupipafupi gulu ntchito multilayer dongosolo resonant mtundu, zomwe zigwirizana zowonetsera angapo kufanana ndi perforations osiyana ndi mipata mpweya wa makulidwe osiyana.

Zida "Shumanet Eco"

Zikuimira wosanjikiza lamayimbidwe anafuna kuti ntchito partitions chimango, mapepala pomangira plasterboard kapena zomangamanga wa kudenga inaimitsidwa. Iwo mwa mawonekedwe a mbale ulusi hydrophobized galasi, amene laminated ndi galasi. Nkhani ntchito ndi inert binder zochokera akiliriki, kupanga phokoso kungolandira mapanelo nonflammable.

NKHANI buku lalikulu danga

Tikumbukenso kuti m'madera kuti ndi buku mkulu, zotsatira za kuchepetsa nthawi reverberation chifukwa yomanga zina phokoso mayamwidwe si chachikulu chotere. Nyumba zonse reverberation nthawi chifukwa mawonekedwe a kudenga ndi mpanda. Mwachitsanzo, ntchito kudenga sanali athyathyathya ndipo anamaliza ndi pilasters wa mosiyanasiyana kapena makonde pa makoma akupanga chachikulu phokoso mayamwidwe. mawonekedwe mfundo mapulani limachititsa kupeza diffuseness minda lamayimbidwe kwambiri lomwe lili ndi ubwino pa lamayimbidwe m'nyumba nyengo.

Iwo ayenera kukumbukira kuti okwana phokoso kuchepetsa holo kwambiri chifukwa pamaso zokongoletsa, mipando mosavuta, makatani. Kuyenera n'komwe posankha liza zipangizo, kuti kukatenga mayamwidwe phokoso. Sound mayamwidwe Pankhaniyi kwambiri.
