Nrog rau kev loj hlob sai ntawm kev lag luam kiv puag ncig, tib neeg tau tsim ib txheej tshiab ntawm "kev lag luam suab" ntxiv rau lub suab ntawm xwm. Qhov tshwm sim ntawm "kev lag luam suab" lees paub cov hneev taw ntawm kev tsim kho kev lag luam. Txawm li cas los xij, hauv txoj kev loj hlob ntawm "kev lag luam suab" , inevitably tshuav ib "kev puas tsuaj" - suab nrov, yog li "suab nrov" tiv thaiv kev sib ntaus sib tua pib.
Tam sim no, cov khoom siv suab nrov nrov thiab txo qis hauv kev ua lag luam muaj xws li polyester fiber, iav ntaub plaub, polyurethane ua npuas ncauj, inorganic ua npuas ncauj hlau cov ntaub ntawv, thiab lwm yam. Raws li tam sim no inorganic ua npuas ncauj hlau cov ntaub ntawv nrog tus nqi zoo tshaj plaws thiab kev ua tau zoo, nws lub suab zoo. rwb thaiv tsev thiab suab nrov txo peev xwm yog 7-10 npaug ntawm polyurethane ua npuas ncauj, iav fiber, thiab honeycomb txhuas. Thaum siv rau cov tsheb ciav hlau ceev thiab lub tsheb lub thawv, lub suab rwb thaiv tsev yog ze rau 30dB. Raws li cov ntaub ntawv xeem, lub suab rwb thaiv tsev theem ntawm lub suab zoo tib yam cov ntxaij vab tshaus tsuas yog txo los ntawm 5dB, thiab cov khoom ua npuas ncauj aluminium tuaj yeem txo los ntawm 10-20dB.
Nrog rau txoj kev loj hlob ntawm txhuas ua npuas ncauj industrialization, txhuas ua npuas ncauj yog siv nyob rau hauv ntau thiab ntau teb rau nws superior suab nqus thiab suab nrov txo thiab lwm yam khoom, feem ntau nyob rau hauv txoj kev loj suab teeb meem, txoj kev loj tunnel suab nrov txo, submarine tunnel suab nrov txo, thiab qhov cua qhov cua. Suab-absorbing phab ntsa ntawm cov pas dej da dej; kho kom zoo nkauj sab hauv ntawm cov chaw lom zem; ua npuas ncauj aluminium suab rwb thaiv tsev pem teb; ua npuas ncauj aluminium tsim cov tsheb thauj khoom, cov neeg caij tsheb thiab tsheb mufflers; ua npuas ncauj aluminium ntau lawm ntawm lub tsev suab-absorbing linings, xws li cov ntaubntawv povthawj siv studios, dubbing chav, concert halls, rooj sablaj halls, stadiums, thiab lwm yam.
