Lub suab nrov txo qis coefficient ntawm cov khoom siv aluminium tshiab nce mus txog 0.75, thiab lub suab nqus coefficient hauv nruab nrab zaus ntawm 250 ~ 1000Hz mus txog ntau dua 0.9, deb tshaj li cov khoom siv suab nrov nrov xws li pob zeb wool, gypsum board. , perforated hlau phaj, thiab lwm yam. Nws ua tiav lub suab rwb thaiv tsev thiab suab nrov txo peev xwm yog polyurethane ua npuas ncauj. Nws yog 7-10 npaug ntawm cov yas, iav fiber ntau thiab honeycomb aluminium, thiab nws lub suab rwb thaiv tsev yog ze rau 30dB thaum siv hauv cov tsheb ciav hlau ceev thiab lub tsheb lub thawv panels. Cov khoom siv aluminium tshiab yog siv nyob rau hauv ntau thiab ntau lub teb rau nws cov suab nrov zoo dua thiab txo cov suab nrov thiab cov khoom muaj feem xyuam, feem ntau nyob rau hauv txoj kev loj suab teeb meem, txoj kev loj tunnel suab nrov txo, submarine tunnel suab nrov txo, qhov vents; suab nqus ntawm phab ntsa da dej; tshiab ua npuas ncauj aluminium cov ntaub ntawv los ua lub tsev suab-absorbing hauv ob sab phlu, xws li cov ntaubntawv povthawj siv studios, dubbing chav, concert halls, lub rooj sib tham halls, stadiums, thiab lwm yam.
Lub ntsiab tseem ceeb cuam tshuam rau lub suab nqus thiab suab nrov txo cov nyhuv ntawm cov ntaub ntawv tshiab ua npuas ncauj yog raws li hauv qab no:
1. Cov khoom siv tshiab aluminium ua npuas ncauj yog cov khoom ntxeem tau, thiab nws qhov kev ua haujlwm zoo ntawm lub suab yog pom tseeb dua rau lub suab nrov zaus, uas yog hais tias, lub suab nqus coefficient yog loj hauv cheeb tsam siab. Txawm li cas los xij, lub suab nqus cov nyhuv ntawm lub suab qis tsis zoo heev, yog li lub suab nqus coefficient hauv cheeb tsam tsawg zaus me me;
2. Lub thickness ntawm lub suab-absorbing vaj huam sib luag ua los ntawm cov ntaub ntawv tshiab ua npuas ncauj aluminium yog txawv, thiab lub suab-absorbing zaus txawv. Raws li lub thickness nce, lub suab-absorbing zaus yuav tsim nyob rau hauv cov kev taw qhia ntawm absorbing tsawg zaus. Txawm li cas los xij, thaum lub suab nrov ntau dua 500Hz, lub suab nqus coefficient ntawm cov khoom siv tshiab ua npuas ncauj aluminium tsis muaj dab tsi cuam tshuam nrog lub thickness;
3. Thaum qhov ntom ntom ntawm cov khoom siv aluminium tshiab nce, lub suab nrov nrov ntawm lub sijhawm no tseem yuav tsim kom muaj suab nrov tsawg, thiab qhov loj thiab qhov loj ntawm lub qhov hws ntawm cov khoom siv aluminium tshiab kuj muaj qhov sib txawv ntawm lub suab. absorption kev ua tau zoo ntawm lub suab-absorbing vaj huam sib luag.
Txhawm rau muab nws yooj yim, kev xaiv sib txawv ntawm cov ntaub ntawv aluminium tshiab, xws li tuab, ntom, porosity, thiab lwm yam, yuav ua rau muaj kev sib txawv ntawm lub suab nrov. Txawm li cas los xij cov ntaub ntawv tshiab aluminium ua npuas dej raug xaiv, nws zoo dua kom haum rau lawv tus kheej qhov xwm txheej.
