I-foam ye-aluminium yeseli ibhekisela kwi-foam ye-aluminium emingxuma yangaphakathi edibeneyo, kunye nobukhulu be-pore ye-0.5-1.0 mm, i-porosity ye-70-90%, kunye ne-porosity ye-55-65%. ukusebenza okugqwesileyo kokufunxa isandi kunye nokumelana nomlilo ngenxa yeempawu zayo zetsimbi kunye nesakhiwo se-porous. I-coefficient yokunciphisa ingxolo i-NRC> 0.75, ukulinganiswa komlilo ngu-A1, kunye ne-foam ye-aluminium ngokusebenzisa i-foam inokwenziwa ngokwezifiso ngokuchasana nokuhamba okuhlukeneyo kunye neendawo ezahlukeneyo zokungena kwi-hole (ngokusebenzisa i-hole ratio). Phantsi kweemeko eziqhelekileyo, indlela yokufunxa isandi se-aluminium ye-foam ngokusisiseko ixhomekeke kwisandi se-viscous ukufunxa kunye nokufunxa isandi sokuqhuba kwe-thermal. Isiphumo sokufunxa isandi kulo mzekelo asicacanga.I-foam ye-aluminium ye-cell esivelisayo yenza ukuba isakhiwo se-foam ye-aluminium sihambelane ngakumbi nesakhiwo somsindo. Iitshaneli ezincinci kunye neeseli ezenziwe ngaphakathi zenza inani elikhulu lee-cross-sections ngokukhawuleza kunye nenani elikhulu le-Helmholtz ye-resonant cavities ene-side-branched ukufezekisa ukufunxa isandi. Ngokukodwa, isiphumo sokufunxa isandi kwi-frequencies ephakathi kunye nesezantsi ngokucacileyo ingcono kunemathiriyeli yemveli.
