Tam sim no nrog kev txhim kho txuas ntxiv ntawm zej zog, suab nrov tau dhau los ua ib qho ntawm cov khoom ua paug ib puag ncig, yog li tam sim no lub tsev suab teeb meem ib puag ncig ntau dua thiab ntau dua thiab mloog, xaiv lub suab tsim nyog.absorbing boardrau kev kho suab nrov hauv tsev yog qhov feem ntau siv lub tsev suab nrov tswj engineering ib qho ntawm cov kev ntsuas yooj yim tshaj plaws.
Qhov sib txawv ntawm cov khoom siv suab nrov thiab cov khoom siv suab rwb thaiv tsev yog tias lub suab nqus ntawm cov khoom siv tsom mus rau qhov loj ntawm lub suab rov qab lub zog ntawm sab ntawm lub suab nrov, thiab lub hom phiaj yog kom muaj kev cuam tshuam lub suab zog tsawg dua.Cov khoom siv suab rwb thaiv tsev saib qhov loj ntawm qhov sib kis suab lub zog ntawm sab nraud ntawm qhov xwm txheej suab nrov, thiab lub hom phiaj yog ua kom lub suab sib kis tau me dua.Cov khoom siv suab nrov rau qhov tshwm sim ntawm lub zog ntawm lub zog ntawm qhov nqus, feem ntau tsuas yog ob peb kaum, yog li ntawd, nws lub suab nqus muaj peev xwm xws li suab nqus coefficient tuaj yeem hais tawm hauv cov lej lej thiab suab rwb thaiv tsev.
Lub zog xa hluav taws xob tuaj yeem txo qis rau 10-3 ~ 10-4 ntawm qhov xwm txheej suab lub zog lossis tsawg dua.Rau qhov yooj yim ntawm kev qhia, lub suab rwb thaiv tsev ntim yog sawv cev los ntawm txoj kev ntsuas decibel.Ob cov ntaub ntawv nyob rau hauv cov khoom sib txawv yog absorbing cov ntaub ntawv ntawm qhov teeb meem suab lub zog reflection yog heev me me, uas txhais tau hais tias lub suab lub zog yog ib qho yooj yim mus nkag tau thiab los ntawm cov khoom: koj muaj peev xwm xav txog tej yam, cov khoom ntawm cov khoom yuav tsum porous sulfur thiab breathable, Qhov no yog cov khoom siv ntxeem tau zoo, feem ntau yog cov khoom siv fiber ntau, rub los yog foaming los tsim cov qauv ntxeem tau: nws cov qauv yog: cov khoom muaj ntau tus, sib cuam tshuam, los ntawm lub rooj mus rau lub qhov, uas muaj qee yam permeability, Thaum lub suab nthwv dej rau hauv cov khoom ntxeem tau nto, ua rau huab cua hauv kev co, vim muaj kev sib txhuam thiab huab cua nplaum
Qhov kev tiv thaiv zoo li qub thiab cov hluav taws xob hluav taws xob hloov pauv ib feem ntawm lub suab lub zog rau hauv lub zog hluav taws xob, yog li ua si suab nrov.Rau lub suab rwb thaiv tsev cov ntaub ntawv, kom tsis muaj zog kis tau tus mob ntawm lub zog ntawm lub suab, thaiv kev sib kis ntawm lub suab, tsis yog li ntxeem tau raws li cov khoom siv suab nrov, ntxeem tau, breathable, ntawm qhov tsis tooj, nws cov khoom yuav tsum hnyav thiab ntom, xws li steel phaj, txhuas. phaj, cib ntsa thiab lwm yam ntaub ntawv.Qhov yuav tsum tau ntawm cov khoom siv suab rwb thaiv tsev yog tuab yam tsis muaj qhov pores lossis qhov khoob: muaj qhov hnyav loj, vim tias cov khoom siv suab nrov no yog qhov ntom ntom, nws nyuaj rau nqus thiab dhau los ntawm lub suab lub zog thiab cuam tshuam los ntawm txawm tias, yog li nws lub suab nqus tau zoo. tsis zoo.
Hauv engineering, lub hom phiaj thiab qhov tseem ceeb ntawm kev ua suab nrov thiab kev ua suab rwb thaiv tsev yog txawv.Lub hom phiaj ntawm kev kho lub suab nrov yog txo qis qhov rov qab xav txog ntawm lub suab, uas yog, txo lub sijhawm sib xyaw ntawm lub suab nrov, thiab lub suab nrov tsis tu ncua txo qis hauv qhov txo qis ntawm cov suab nrov sab hauv tsev, uas yog nyob rau hauv tib lub tsev. qhov chaw ntawm lub suab nrov thiab cov khoom siv suab nrov.Thiab rau lub suab los ntawm chav nyob ib sab, cov khoom siv suab nrov kuj ua lub luag haujlwm nqus, uas yog sib npaug rau kev txhim kho lub suab rwb thaiv tsev ntim ntawm lub hnab ntawv qauv.
