Kupyolera mu cell aluminium thovu amatanthauza thovu la aluminiyamu lomwe ma pores ake amkati amalumikizana, ndi pore kukula kwa 0.5-1.0 mm, porosity ya 70-90%, ndi porosity ya 55-65%. kumveka bwino kwa mayamwidwe ndi kukana moto chifukwa cha mawonekedwe ake achitsulo komanso mawonekedwe a porous. Phokoso lochepetsera phokoso la NRC> 0.75, mlingo wamoto ndi A1, ndipo thovu la aluminiyamu lodutsa m'bowo likhoza kusinthidwa ndi kukana kosiyana kosiyana ndi ma apertures osiyanasiyana odutsa-bowo (kupyolera mu chiŵerengero cha dzenje). Nthawi zonse, kachitidwe ka mayamwidwe a thovu aluminiyamu kwenikweni amadalira mayamwidwe a viscous sound ndi mayamwidwe a matenthedwe amawu. Phokoso la mayamwidwe a phokoso pankhaniyi silodziwikiratu.Kupyolera mu cell aluminium thovu yomwe timatulutsa imapangitsa kuti mawonekedwe a thovu a aluminiyumu azikhala ogwirizana ndi mawonekedwe otulutsa mawu. Tinjira tating'onoting'ono ndi ma cell omwe amapangidwa mkati mwake amapanga timagulu tambiri tambiri tomwe timadumphira modzidzimutsa komanso mikwingwirima yambiri yam'mbali ya Helmholtz kuti imve bwino. Makamaka, mayamwidwe amawu apakati ndi otsika ma frequency ndi abwinoko kuposa zida zachikhalidwe.
