Nrog rau txoj kev loj hlob sai ntawm tib neeg lub neej, tib neeg muaj ntau thiab ntau yam khoom thiab kev xav tau ntawm sab ntsuj plig, thiab nrhiav qhov zoo tshaj plaws hauv tsev ib puag ncig. Yog li ntawd cov neeg yuav high-end stereos, vam tias yuav txaus siab rau suab paj nruag hauv tsev; yuav projectors, vam mus saib tsos hauv txaj; yuav treadmills, vam tias yuav tawm dag zog tsis tau tawm hauv tsev. Raws li tib neeg txav chaw ntau dua rau hauv lawv lub tsev, nws tsim nyog tsim teeb meem loj tshaj plaws - suab nrov. Yog li ntawd, kev sib ntaus sib tua "suab nrov" tau pib.
Tam sim no, cov khoom siv suab nrov nrov thiab txo qis hauv kev lag luam muaj xws li polyester fiber, iav ntaub plaub, polyurethane ua npuas ncauj, thiab cov ntaub ntawv ua npuas dej. Raws li tus nqi-zoo tshaj plaws thiab kev ua tau zoo-phooj ywg aluminium ua npuas cov khoom hauv nws cov chav kawm, nws lub suab nrov rwb thaiv tsev thiab lub suab nrov txo lub peev xwm yog 7-10 npaug ntawm polyurethane ua npuas ncauj, iav fiber ntau, thiab honeycomb aluminium. Thaum siv rau cov tsheb ciav hlau ceev thiab tsheb ciav hlau, 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. Raws li kev xeem, nws tau qhia tias:
| Khoom siv | Specification | Noise Reduction Factor/Ntau ntawm Suab rwb thaiv tsev |
| Polyurethane ua npuas ncauj | 35mm tuab | Lub suab nrov txo coefficient yog 0.85NRC |
| Polyurethane ua npuas ncauj | 35mm tuab | Lub suab rwb thaiv tsev yog 23dB |
| Aluminium ua npuas ncauj khoom | 20mm tuab | Noise txo coefficient yog 0.9NRC |
| Aluminium ua npuas ncauj khoom | 20mm tuab | Lub suab rwb thaiv tsev yog 30dB |
Nrog rau txoj kev loj hlob ntawm txhuas ua npuas ncauj industrialization, txhuas ua npuas ncauj yog siv nyob rau hauv ntau thiab ntau lub teb vim nws superior suab nqus thiab suab nrov txo thiab lwm yam khoom, xws li txoj kev suab teeb meem, txoj kev tunnel suab nrov txo, submarine tunnel suab nrov txo, thiab qhov vents; Suab-absorbing phab ntsa ntawm cov pas dej da dej; sab hauv kho kom zoo nkauj 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, lub rooj sib tham halls, Sports venues thiab lwm yam teb, muaj kev ua tau zoo heev.
