Qhov no yog tua neeg ntawm cov dej crane, thiab lub pob taws ntawm lub qhov rooj, thiab cov khoom siv ua haujlwm, tshuab ntxhua khaub ncaws, tshuab ntxhua khaub ncaws, tshuab ntxhua khaub ncaws, TV, cua txias thiab raug yuam kev dim pa), thiab ntau ntxiv. Nws sau ntawv nyob rau hauv cov neeg sau npe rau hauv General Pervus ua suab los ntawm txoj kev thiab los ntawm cov neeg nyob ze. Tag nrho cov no ua ke ua cov thiaj li hu ua lub suab nrov hauv tsev. Hais txog nws, lawv txhais tau tias tsis cais cov suab, txhua tus uas yog qhov cim thiab ntau zaus, tab sis lawv tus kheej spectrum hauv qhov ntau zaus ntawm peb lub pob ntseg.
Nyob rau hauv cov lus qhuab qhia ntawm architectural thiab cov txheej txheem tsim, lub tswv yim ntawm "chav acoustics" yog cov hauv paus khov kho. Hauv kev coj ua, nws cuam tshuam cov teeb meem ntawm ob qho teeb meem cuam tshuam: tiv thaiv chav sib cuam tshuam ntawm cov suab los ntawm sab nraud thiab ua kom muaj txiaj ntsig zoo rau cov suab nrov hauv nws. Ob qho tib leeg muaj kev txo qis hauv lub zog ntawm lub suab tsis muaj zog, tab sis thawj zaug yog thaum lub suab rwb thaiv tsev), thiab qhov thib ob yog cuam tshuam los ntawm cov barrier (lub cev nqus).
Txog tam sim no, acoustics ntawm vaj tse nyob rau hauv Russia tsis muaj txaus. Ua ntej, vim li cas ntawm cov nyiaj (raws li cov kws tshaj lij ntawm lub tuam txhab project "Svenson", yog li tus nqi kev tsim kho poob qis dua li 30%). Thib ob, vim tias tsis muaj kev tswj hwm raws li cov yam ntxwv kev tswj hwm ntawm cov acoustics ntawm thaj chaw nyob. Ib kauj ruam siv tau rau kev tshem tawm ntawm cov laj thawj no tuaj yeem raug txiav txim siab nyob rau xyoo 1994-97 "muaj suab npe thiab cov vaj tse nyob rau hauv vaj tse nyob", coj mus siv hauv peev.
Cov neeg tsim khoom ntawm acoustic cov ntaub ntawv tau nthuav dav cov ntau ntawm lawv cov khoom. Kev siv zog ntawm cov tuam txhab xws li Fabkis Saint-Grocain, Witch Brotex, Finuguese ipocorc, nrog rau cov chaw tsim khoom ntawm acoustic tshem tawm cov actutcom, USG, German amf, domesic "acoustic cov ntaub ntawv", "yog ib tus neeg nyob hauv Lavxias-lus, peb lub lag luam tau ua tiav nrog cov ntaub ntawv tsim ntawm cov kev taw qhia no.
Cov cua nrov cua thiab cov suab nrov yog cov qauv
Lub suab nrov yuav yog ib qho kev ua txhua yam, xws li txav rooj tog rau hauv pem teb los yog txhaws ntsia hlau rau hauv phab ntsa. Xws li lub suab nrov hu ua qauv. "Ua haujlwm" ntawm cov phiaj xwm hauv qab no: Kev co hauv pem teb los ntawm peb cov kauj ruam yog kis los ntawm phab ntsa, thiab nws cov oscillations tau hnov hauv chav txuas ntxiv. Lub suab tsis zoo tshaj plaws uas tsis muaj suab nrov yog pogsion. Nws feem ntau sib kis dhau qhov kev ncua deb ntawm qhov chaw. Cia peb hais, khob ntawm cov cua kub hauv nruab nrab ntawm tib chav tsev tau hnov ntawm txhua tus neeg lwm tus thiab pom los ntawm cov neeg nyob hauv tsev, zoo li nws lub hauv paus yog qhov ze heev. Lub 4 lub rooj kawg muaj cov yam ntxwv ntawm cov suab paj nruag xws li.
Qee cov khoom siv hauv yim neeg yog cov khoom siv ntawm ob hom suab nrov. Piv txwv li, lub system ntawm kev yuam kev dim pa. Cov suab nrov cua nkag mus rau hauv chav tsev los ntawm cov huab cua ducts, thiab cov txheej txheem tshwm sim los ntawm cov phab ntsa kev sib cav ntawm lub kiv cua thiab huab cua lawv tus kheej.

Suab thiab suab nrov
Hauv kev sib tham, ob lo lus ze tau siv nyob rau hauv lub ntsiab lus ntawm lo lus: "suab" thiab "suab nrov". Lub suab yog qhov tshwm sim ntawm lub cev los ntawm kev txav ntawm kev txav ntawm kev txav ntawm cov me me ntawm nruab nrab. Suab oscillations muaj qee yam amplitude thiab ntau zaus. Yog li, ib tus neeg muaj peev xwm hnov cov suab uas sib txawv hauv cov amplitude nyob rau hauv kaum lab lab ntawm lub sij hawm. Lub caij pom tau pom los ntawm peb lub pob ntseg nyob hauv thaj tsam ntawm los ntawm 16 txog 20000Hz. Suab Zog yog cov cwj pwm los ntawm kev siv (w / m2) lossis suab siab (pa). Xwm tau rhuav tshem peb nrog lub peev xwm tau hnov thiab dov xob quaj, thiab cov nplooj ntoo me me ntawm cov ntoo. Txhawm rau ntsuas cov suab sib txawv xws li, qhov ntsuas ntawm qhov kev ntsuas qib l thiab cov chav tshwj xeeb ntawm kev ntsuas yog kev ntsuas (DB). Los ntawm txoj kev, tib neeg lub rooj sib tham pib sib raug zoo rau suab siab ntawm 210-5PA lossis 0DB. Raws li rau lub suab nrov, nws yog ib qho kev ntxhov siab, tsis nres sib xyaw suab, tsis zoo ua rau lub paj hlwb.Cov rhiab ntawm tib neeg pob ntseg mus rau ntau zaus heev thiab heev ntau zaus yog kev ua phem tshaj li rau cov kev hais lus (500-4000 hz). Thaum ntsuas kev ntsuas, nws yog ib qho yuav tsum tau coj mus rau hauv tus account ntawm lub rooj sib hais no. Dhia los ntawm Notisomer siv cov nplai tshwj xeeb "" nrog cov units ntawm "Decibelimia" (DBA). Los ntawm cov chav kawm ntawm cov ntau lawv yuav luag cocuralic nrog decosting decibels.
Lub cev tus yam ntxwv ntawm lub suab yog nws ntim. Txo cov qib ntawm kev siv ntawm lub suab l per 10db yog muaj kev cuam tshuam raws li kev txo qis hauv 2 zaug, thiab 5db- raws li kev txo qis hauv ib feem peb.
Tib neeg lub cev tsis teb rau cov suab nrov ntawm cov qib sib txawv thiab cov zaus muaj pes tsawg leeg. VDIAPAZONE 35-60 DBA yog tus kheej (los ntawm hom "cuam tshuam-nggels"). Lub suab nrov ntawm qib ntawm 70-90 dba nrog ntev sprosing ua rau tus kab mob ntawm lub paj hlwb, thiab nrog l ntau dua 100 dB-confinity acuity ntawm kev loj hlob ntawm kev txhim kho ntawm kev ua tiav lag ntseg.
Txoj kev rau rwb suab nrov
Lub suab nrov nrov rau sab nraud yog txwv twb tau txwv lawm ntawm theem kev tsim kho. Qhov no yog ua tiav raws li kev ua raws li kev cai tswj hwm rau cov soundproofing ntawm cov chaw nyob. Lub "nrov nrov" ib cheeb tsam (chav ua noj, chav dej, ua ke hauv cov ciav hlau, cov kauj ruam zoo sib xws ntawm cov chaw nyob sib ze. Yog tias cov peev txheej tseem ceeb ntawm lub suab nrov ntawm cov kev txwv ntawm vaj tse, thiab cov kev xav tau yam uas xav tau, qhov kev saib xyuas tshwj xeeb yuav tsum tau them rau cov qauv suab ntxiv uas tau muab tso rau hauv ib sab, sab saum toj thiab hauv qab. Cov no feem ntau suav nrog:
- Cov phab ntsa tiv thaiv thiab cov partitions;
- Cov polshes thiab nthab, suav nrog lawv cov pob qij txha nrog phab ntsa thiab partitions;
-Ob thaiv cov pob, cov hauv paus thiab lub rooj lawj;
- Cov cuab yeej nruab rau hauv cov phab ntsa thiab cov cuab yeej qab nthab thiab kev sib txuas lus engineering uas ua rau muaj suab nrov.
Lub suab muaj peev xwm ntawm cov qauv siv hauv kev tsim kho tau siv hauv kev tsim kho yog kwv yees los ntawm qhov tseem ceeb qhov tseem ceeb ntawm Rwb thaiv tsev. Rau cov tsev ntawm qeb "" (siab tshaj plaws), lawv yuav tsum yog 54 thiab 52 teev, rau tsev kawm qeb "B" - 50 thiab 60dB.
Cov suab nrov cua tiv thaiv ntawm ib sab
- Ua li ntawd lub suab nthwv dej tsis muaj peev xwm yuam kom muaj kev thaiv kom haum, thaum lub suab pauv hauv chav;
- Kev nqus thiab rho tawm ntawm lub zog ntawm lub suab yoj sab hauv lub thawv siv
Thawj txoj kev xav tau qhov khuam sij rau yog ib qho loj dua (hnyav), lossis tawv. Qhov thib ob yog siv siv cov neeg siv multilayer cov qauv los ntawm cov khoom siv ntxeem thiab fibrous. Qhov nyuaj thiab tuab monolith thiab ntau zaus monolith thiab tshaj qhov zaus ntawm lub suab, tus me dua ntawm phab ntsa vibrates, thiab, nws txhais tau tias nws lub peev xwm zoo nkauj yog qhov zoo dua. Txawm li cas los xij, kev sib txuas ntawm cov teeb meem no tsis ncaj. Yog li, ib phab ntsa qhob ntawm ib qho tuab ntawm 1400 hz ua ntu zus ntawm 300 hz soundproofing nyob rau hauv tsuas yog 39db, thiab ntawm ib zaus ntawm 1600 gg yog li 60 db. Txhim kho tus nqi ntawm RW Performance index los ntawm nce qhov loj ntawm cov qauv tsis yog qhov ua tau zoo li nws zoo li. Yog hais tias plastered phab ntsa hauv pollipich (150 hli tuab) yuav muab suab rwb thaiv tsev hauv 47db, ces plastered phab ntsa tuab nyob rau hauv cib tsuas yog 53-54 dB. Hauv lwm lo lus, cov npaug ntawm cov huab hwm coj yuav txhim kho lub suab rwb thaiv tsev ntawm tsuas yog 6-7 dB.
Tus tswj hwm cov qauv ntau muaj cov ntawv txheeb ntawm cov khoom sib txawv, nruab nrab ntawm cov pa dej yuav ua tau. Nyob rau hauv xws li qauv, kev co nrawm nrawm dua li hauv cov khoom siv homogeneous. Lub suab nrov ntawm cov "Puff" partitions ntawm lub ntom me me yog piv rau cov khoom ntawm monolithic phab ntsa. Yog li, ib qho septum tuab ntawm 150mm nrog 40-hli txheej ntawm cov muab tub lim los ntawm cov ntawv me me thiab cov cua sov ntawm 12,5 txhua tus, yuav muab cov suab nrov sab nraud (5) db. Qhov no yog txaus los tiv thaiv cov suab nrov tau tsim los ntawm cov khoom lag luam hauv lub neej txhua hnub.

Yog li koj yuav tiv thaiv kev nkag mus ntawm lub suab yoj los ntawm cov pores.
3. Hloov cov nplooj ntawv sab hauv ntau ntu nrog ob txheej sab hauv hauv ob txheej yog qhov zoo dua nrog cov tog ntawm ib txheej txheeb ze rau lwm yam.
4. Hauv cov embedding ntawm cov khoom siv teeb pom kev zoo hauv cov phab ntsa thiab tsis hnov qab ua tib zoo mloog cov qhov khoob thiab khoob. Lawv tuaj yeem txo cov suab rwb thaiv tsev ntawm cov qauv txuas.
Sealing Chaav Thiab Soundproofing Engineering Khoom
Cov pob hauv qab lub qhov rooj, cov khoob thiab cov ntu, ntsuas kub, kub thiab shrinkage seams ib txwm ua mob rau lub suab ntawm chav. Yog li, lub 15-millimeter qhov chaw nyob sab nraud nyob rau hauv lub qhov rooj sab hauv yuav txo cov rw partitions los ntawm ntau li 5-9 dB. Tshauv-drift lub qhov hluav taws xob rau cov hluav taws xob hauv phab ntsa cais cov chav tsev, txawm tias qhov ntsuas RW = 50DB, yuav tso cai nrog cov neeg nyob sib ze. Nws yog vim li no uas qhov kev ua pa tawm ntawm cov qhov rooj sab hauv yuav tsum tau muab cov ntaub thaiv npog. Lub zog hluav taws xob ua rau kev nkag siab nrog kab rov tav nrog kev hloov chaw, yog li rhuav tshem lub loopholes rau suab nrov. Nco ntsoov tias qhov no lub suab sib khi ua ke daws teeb meem ntawm ob lub rwb thaiv tsev thermal thiab rwb thaiv tsev suab.
Nws yuav tsum tau them nyiaj rau lub suab rwb thaiv tsev ntawm ib qho khoom siv ntxiv tau ua rau hauv phab ntsa thiab qab nthab. Piv txwv li, nws ua rau kev nkag siab los tsim kev khuam siab ntawm txoj kev ntawm cov suab nrov uas tshaj tawm hauv cov thawv thiab huab cua hauv cua tshuab. Lo lus nug no hauv txhua kis tshwj xeeb yog daws hauv nws txoj kev.
Kev Tiv Thaiv
Txhawm rau tshem tawm qhov ua tau hluav taws los ntawm cov ntaub ntawv tsis muaj suab, lawv yuav tsum xa mus rau chav kawm ntawm tsis-commly (ng) lossis yog li-taws (B1). Piv txwv li, cov ntxhia pob zeb thiab cov neeg sawv cev fiberglass-neeg sawv cev ntawm NG chav kawm, polystyrene ua npuas ncauj thiab plug-in1 (thaum ua nrog antipiren). Avot polynesenethan-guryuch (chav kawm). Pom zoo cov ntaub ntawv tswj cov ntaub ntawv muaj cov cai rau kev nyab xeeb siv cov khoom siv hluav taws xob ua haujlwm kom txog thaum muaj. Tias yog vim li cas thaum txuas cov khoom lag luam rau phab ntsa lossis ntoo ntoo, yuav tsum muaj kev pheej hmoo ntawm lawv qhov kev tiv thaiv ntawm sab hauv ntawm chav. Hais tias, nruab ib daim ntawv hlau tom qab lawv. Qhov slab los ntawm cov khoom siv yuav tsum muaj daim ntawv pov thawj kev tu kom paub tseeb tias qhov tsis muaj kev phom sij rau kev noj qab haus huv. Tsev kho mob, feem ntau ntawm cov npe teev cov npe nyob hauv qab ntawm qhib hluav taws yuav haus luam yeeb thiab paub qhov txawv toxic roj.
Tus kws kho ntawv kho ua tsaug rau lub tuam txhab "acoustic cov ntaub ntawv", "lub chaw ua haujlwm SanStif", "Lub Chaw Haujlwm Sib Tw", "Lub Chaw Haujlwm Sib Koom Tes" Tus kws tshawb fawb Niizf A. A. Klimukhin rau kev pab hauv kev npaj cov khoom siv.
