Acoustic iav, tseem hu ua soundproof iav los yog lub suab nrov-txo iav, yog ib hom iav uas yog tsim los txo cov kev sib kis ntawm suab tsis. Nws yog feem ntau siv hauv cov tsev thiab tsheb los tsim kom muaj qhov chaw ntsiag to thiab xis nyob los ntawm kev txo cov suab nrov sab nraud.
Acoustic iav feem ntau muaj ob los yog ntau txheej ntawm iav nrog ib qho interlayer ntawm acoustic khoom, xws li polyvinyl butyral (PVB) los yog ethylene-vinyl acetate (EVA), sandwiched ntawm lawv. Lub interlayer ua raws li cov khoom damping, absorbing thiab dissipating suab zog thaum nws dhau los ntawm iav.
Lub thickness thiab muaj pes tsawg leeg ntawm cov iav, nrog rau cov khoom siv interlayer, tuaj yeem sib txawv nyob ntawm qhov xav tau ntawm lub suab txo. Cov iav tuab dua thiab ntau dua interlayer feem ntau ua haujlwm zoo dua ntawm kev txo suab nrov.
Ntxiv rau nws cov khoom siv suab nrov, acoustic iav tseem muab lwm cov txiaj ntsig xws li kev txhim kho thermal rwb thaiv tsev, tiv thaiv UV, thiab kev ruaj ntseg. Nws tuaj yeem siv rau hauv qhov rais, qhov rooj, muab faib, thiab lwm yam kev siv uas xav tau kom txo suab nrov.
Sound Transmission Class (STC) yog qhov ntsuas qhov ntsuas uas ntsuas cov khoom siv lossis kev tsim kho kom zoo npaum li cas tuaj yeem txo qhov kev sib kis ntawm huab cua.
STC ntsuas ntsuas qhov ntsuas ntawm 25 txog 60 lossis siab dua, nrog cov lej siab dua qhia tias muaj suab nrov zoo dua. Cov iav sib txawv muaj qhov sib txawv STC qhov ntsuas nyob ntawm lawv qhov tuab, muaj pes tsawg leeg, thiab lwm yam ntxiv suab pov thawj uas lawv yuav muaj. Piv txwv li, ib leeg-pane iav feem ntau muaj STC qhov ntsuas ntawm ib ncig ntawm 25-30, thaum ob lossis triple-pane iav nrog cov khoom siv hluav taws xob tuaj yeem muaj STC qhov ntsuas ntawm 35 txog 50 lossis siab dua.
