Kuburikidza ne-cell aluminum foam zvinoreva furo realuminium iro mukati maro maburi akabatana, ane pore saizi ye0.5-1.0 mm, porosity ye70-90%, uye kuburikidza-porosity ye55-65%. yakanakisa kurira kwekuita uye kuramba moto nekuda kweiyo yayo simbi maitiro uye porous chimiro. Iyo yekudzikisa ruzha coefficient NRC> 0.75, iyo moto chiyero ndeye A1, uye kuburikidza-gomba aluminium furo inogona kugadziridzwa nekusiyana kwekuyerera kwekupokana uye akasiyana kuburikidza-gomba apertures (kuburikidza ne-gomba reshiyo). Mumamiriro ezvinhu akajairwa, iyo inonzwika yekunyudza meshini yefoam aluminium inotsamira pane viscous ruzha kunyudzwa uye kupisa kwekuita ruzha kutorwa. Inzwi rekupinza mutsindo munyaya iyi haisi pachena.Iyo kuburikidza ne-cell aluminium foam yatinogadzira inoita kuti chimiro chealuminium foam chiwedzere kuenderana ne-sound-absorbition structure. Iwo madiki machane uye maseru akaumbwa mukati anoumba huwandu hukuru hweakangoerekana achinjika-zvikamu uye huwandu hukuru hwepadivi-mabazi Helmholtz resonant cavities kuti iwane kutorwa kwezwi. Kunyanya, iyo inzwi yekunyudza mhedzisiro yepakati uye yakaderera frequencies zviri pachena zviri nani pane izvo zvechinyakare zvinhu.
