Cov txheej txheem kev teeb tsa ntawm lub suab- nqus cov ntaub ntawv ncaj qha txiav txim siab seb lawv qhov kev ua haujlwm acoustic tuaj yeem siv tau tag nrho thiab cuam tshuam rau qhov zoo thiab ua haujlwm ntawm qhov project. Vim muaj ntau hom kev nqus suab nrov thiab cov ntaub ntawv cov ntaub ntawv, cov qauv kev teeb tsa yuav tsum xav txog cov yam ntxwv ntawm cov khoom sib txawv thiab cov kev xav tau ntawm ib puag ncig kev teeb tsa, tsim cov txheej txheem kev qhia ua ntej los ntawm kev npaj ua ntej rau kev lees txais.
Ua ntej kev tsim kho, ntawm -kev soj ntsuam ntawm qhov chaw thiab kev tshuaj xyuas cov qauv tsim acoustic yuav tsum tau ua. Lub ntim ntawm lub hom phiaj qhov chaw, lub sij hawm reverberation uas twb muaj lawm, thiab suab nrov spectrum yuav tsum tau txiav txim siab kom paub meej tias hom, specifications, layout, thiab kev pab them nqi cheeb tsam ntawm lub suab -absorbing cov ntaub ntawv, zam tsis txaus los yog ntau tshaj lub suab nqus vim kev xam yuam kev. Qhov chaw nyob ntawm - ib puag ncig yuav tsum ua kom tau raws li qhov kev tsim kho yooj yim: lub hauv paus saum npoo yuav tsum tiaj tus, qhuav, thiab huv si, tsis muaj roj stains, plua plav, thiab qhov tsis sib xws tseem ceeb; cov ntaub ntawv rhiab rau cov av noo (xws li ib co fiber ntau-raws li los yog ntoo composite panels) yuav tsum tau ntsia thaum lub ambient kub thiab av noo raws li cov ntaub ntawv uas yuav tsum tau, feem ntau yog ambient kub ntawm 15-30℃thiab ib tug txheeb ze av noo tsis tshaj 70%.
Kev kho mob hauv paus yog qhov yuav tsum tau ua ua ntej txhawm rau ua kom muaj kev sib raug zoo thiab kho cov teebmeem. Cov pob zeb lossis mortar hauv paus yuav tsum yog cov khoom tsis muaj voids, thiab yuav tsum tau ua hauv av lossis kho yog tias tsim nyog; ntoo lossis hlau thav duab yuav tsum tau muab ntsia kom ruaj ntseg raws li qhov tsim qhov sib txawv, nrog rau qhov verticality thiab flatness yuam kev tswj tsis pub dhau qhov kev teev tseg (xws li, Tsawg dua los yog sib npaug li 3mm / 2m), thiab xyuas kom meej tias lub zog ntawm lub thav duab txaus los nqa qhov hnyav ntawm lub suab- nqus cov ntaub ntawv thiab muaj peev xwm cuam tshuam cov loads. Rau cov suab nrov resonant-absorbing cov qauv uas yuav tsum tau khaws cia cov kab noj hniav, cov kab noj hniav qhov tob thiab airtightness yuav tsum raug tswj kom tsis txhob ua kom tsis muaj zog ntawm qhov tsawg- zaus suab nqus vim lub suab to lossis cov qauv xoob.
Cov txheej txheem kev teeb tsa yuav tsum ua raws li cov khoom siv - kev tsim kho tshwj xeeb. Lub suab ntxeem tau-absorbing vaj huam sib luag tuaj yeem sib txuas nrog cov khoom zoo ib puag ncig nrog kev pabcuam tag nrho lossis qhov chaw sib txuas, ua kom muaj kev sib raug zoo nrog lub hauv paus txheej thiab txo cov suab txuas; rau thaj chaw loj lossis thaj chaw uas yuav tsum tau muab tshem tawm thiab kev saib xyuas, cov hlua khi hlua khi, cov hlua khi, los yog cov ntaub thaiv npog yuav tsum tau siv. Qhov sib nrug ntawm cov ntsiab lus kho yuav tsum ua tau raws li cov qauv tsim thiab sib npaug sib npaug los tiv thaiv vaj huam sib luag deformation lossis detachment. Saj zawg zog suab-absorbing cov ntaub ntawv (xws li xav thiab mos ua npuas ncauj) yuav kho nrog battens los yog zais rau tes kom tsis txhob ncab los yog wrinkling cuam tshuam lub continuation ntawm lub suab -absorbing nto. Perforated panels nrog ib tug resonant qauv yuav tsum tau ua raws li lub suab -absorbing txheej los yog kab noj hniav tom qab lawv, thiab tej deviation nyob rau hauv lub qhov chaw yuav tsum tsis txhob cuam tshuam lub stability ntawm lub resonant zaus. Txoj kev tsim kho feem ntau pib los ntawm sab hauv mus rau sab nraud thiab los ntawm sab saum toj mus rau hauv qab, txo qis kev sib kis{10}}kev sib kis thiab kev cuam tshuam thib ob.
Kev sib koom ua ke thiab kaum kev kho mob tshwj xeeb yog qhov tseem ceeb rau kev ua haujlwm acoustic. Qhov sib txawv ntawm lub suab-absorbing vaj huam sib luag yuav tsum tau tswj nyob rau hauv cov kev txwv tsim, siv muab tub lim strips ntawm tib yam khoom los yog suab-absorbing sealant los tiv thaiv lub suab zog los ntawm qhov khoob; cov ces kaum yuav tsum tau koom nrog smoothly thiab ncaj, tsis txhob muaj qhov sib txawv los yog cov kauj ruam tsis sib haum xeeb uas ua rau cov chaw cuam tshuam hauv zos. Rau lub suab- nqus cov ntaub ntawv uas yuav tsum tau kho kom zoo nkauj saum npoo, pleev xim los yog lamination yuav tsum tsuas yog ua tom qab kev tsim kho acoustic tau dhau los soj ntsuam, txhawm rau tiv thaiv cov txheej txheej los thaiv qhov pores thiab txo cov suab nrov.
Kev tswj kom zoo yuav tsum tau muab coj los siv thoob plaws hauv tag nrho cov txheej txheem. Thaum lub sij hawm tsim kho, random sampling kev soj ntsuam yuav tsum tau ua los xyuas qhov firmness ntawm fixings, nruj ntawm cov pob qij txha, thiab cov nto flatness; Tom qab ua tiav, kev kuaj acoustic yuav tsum tau ua raws li lub teb chaws tus qauv lossis kev lag luam specifications los xyuas seb lub sij hawm reverberation thiab suab nqus coefficient ua tau raws li qhov yuav tsum tau ua. Hais txog kev nyab xeeb, kev tswj xyuas plua plav thiab suab nrov yuav tsum tau ua thaum txiav lossis drilling, thiab cov neeg ua haujlwm yuav tsum hnav tsom iav thiab qhov ncauj qhov ntswg; Cov khoom siv hluav taws xob yuav tsum tau khaws cia kom deb ntawm cov nplaim taws, thiab hluav taws kub - cov khoom siv sib ntaus sib tua yuav tsum tau yooj yim.
Hauv cov ntsiab lus, cov qauv kev tsim kho rau lub suab- cov ntaub ntawv nqus tau yog nyob rau hauv kev tswj hwm ib puag ncig, kev kho substrate, kev tsim kho, kev sib khi kom ntxaws, thiab kev kuaj pom zoo, tsim kom muaj kev sib txuas zoo sib xws. Kev ua raws li cov qauv no tsis yog tsuas yog ua kom muaj kev ua tau zoo ntawm kev ua haujlwm ntawm lub suab, tab sis kuj tseem txuas ntxiv lub neej kev pab cuam ntawm cov ntaub ntawv, muab kev txhawb nqa zoo rau kev tsim hluav taws xob acoustic.
