Los ntawm qhov kev xav ntawm kev tiv thaiv ib puag ncig, tag nrho "lub suab tsis xav tau" uas cuam tshuam rau tib neeg txoj kev kawm, kev ua haujlwm, thiab so hauv qee qhov xwm txheej raug suav hais tias yog suab nrov.Xws li kev kub hnyiab ntawm cov tshuab, lub suab nrov ntawm ntau lub tsheb, suab nrov ntawm tib neeg thiab ntau lub suab nrov, thiab lwm yam, yog txhua yam hu ua suab nrov.Nrog rau kev tsim kho kev lag luam, kev thauj mus los, thiab kev tsim kho hauv nroog, nrog rau kev loj hlob ntawm cov pej xeem, kev nce hauv cov vaj tse hauv tsev (TV, thiab lwm yam), ib puag ncig lub suab nrov tau nce zuj zus, thiab nws tau dhau los ua kev phom sij loj rau pej xeem. pollutes tib neeg kev sib raug zoo ib puag ncig.Cov kev tshawb fawb tau pom tias lub suab nrov tshaj 85 decibels yuav ua rau tib neeg ntxhov siab, tib neeg yuav hnov ​​​​lub suab nrov, thiab yog li tsis tuaj yeem mloog zoo rau kev ua haujlwm, ua rau txo qis kev ua haujlwm.

Yog li ntawd, tib neeg xav tau cov khoom siv suab nrov kom txo tau ib feem ntawm lub suab nrov thiab xis nyob dua.High sound-absorbing khoom yog cov ntxhia fiber ntau qab nthab board, fiberglass qab nthab board, pob zeb wool qab nthab board, thiab lwm yam. Cov ntaub ntawv suab-absorbing yog muab faib ua microporous hom thiab fiber ntau hom.Tsis muaj qhov sib txawv tseem ceeb ntawm lawv.Lub hauv paus ntsiab lus ntawm kev nqus suab yog tawm hauv ib qho chaw nkag tau rau lub suab, ib qho channel uas muaj ntau qhov me me txuas nrog ua ke, lossis suav tsis txheeb fibers hla.Lawv tau sib xyaw ua ke los tsim ntau qhov sib txawv me me, tab sis thaum lub suab nkag mus, nws tuaj yeem tawm tsis tau.Vim hais tias txoj kev ntxhov siab dhau thiab ntev, lub suab burrows thiab tsoo rau sab laug thiab sab xis.Hauv cov txheej txheem, nws maj mam siv lub zog thiab muaj cov nyhuv ntawm lub suab nqus.Lub suab ntawm ntau zaus yog absorbed nyob rau hauv ntau zaus.Cov suab nrov nrov muaj qhov luv wavelengths thiab tuaj yeem nqus tau yooj yim, thaum lub suab qis qis muaj qhov ntev wavelengths thiab tuaj yeem nkag tau yooj yim cuam tshuam.Rau cov suab nrov tsawg, nws tsis tsuas yog nyuaj rau insulate suab, tab sis kuj nyuaj rau nqus.Nws tsis zoo li lub suab nrov uas yuav tsoo rau hauv thiab tawm ntawm cov kab me me, tab sis yuav yooj yim mus ncig.Tab sis ntev li ntev tau koj ua cov khoom siv suab nrov rau ib theem, koj tuaj yeem nqus tau qis dua 130Hz.
