Soundproofing ntawm fiberglass boards
Soundproofing ntawm fiberglass boards
Cov iav fiber ntau muaj lub suab rwb thaiv tsev zoo heev thiab lub suab nqus zoo.
Tnws hauv qab no rooj teev lub suab nqus cov iav fiber ntau thiab lwm yam ntaub ntawv nyob rau hauv txawv suab zaus tus lej.
Nws tuaj yeem pom los ntawm lub rooj hais tias lub suab nqus coefficient ntawm iav fiber ntau kuj loj. nrog zaus nce, lub suab nqus coefficient kuj nce ntau.
Lub suab nqus coefficient ntawm ntau yam ntaub ntawv | ||||

Lub suab nqus coefficient ntawm ntau cov ntaub iav sib txawv raws li cov qauv ntaub, kev ntxhib los mos, zoo, thiab thickness ntawm square meters.
Lub suab absorption coefficient ntawm lub suab directional ntws ntawm lub kaum sab xis ntawm 90degreeC yog 60 feem pua ~ 95 feem pua.Thaum lub zaus yog 2500Hz, lub suab nqus coefficient yog 78 feem pua ~ 95 feem pua.
Vim cov iav fiber ntau muaj lub suab nrov nqus coefficient, nws cov khoom tuaj yeem siv rau hauv ntau yam khoom siv acoustic.
