Ipleyiti ye-foam ye-aluminium yeseli evaliweyo yenziwe kwipleyiti ephezulu yokufunxa isandi emva kokunyangwa kwe-perforation (φ2mm umngxuma, umlinganiselo wokubhoboza i-1 ~ 3%), enomsebenzi obalaseleyo wokufunxa isandi, kunye nesantya sokufunxa isandi sinokufikelela kwi-60% ~ 90%. Ngenxa yokuba umphezulu wesi sixhobo ungenayo indiza, unomsebenzi obalaseleyo wokufunxa isandi, kwaye kwangaxeshanye uye wagqobhoza umsebenzi wokufunxa isandi se-Helmholtz resonance resonance absorption ukuqinisekisa isantya esiphezulu sokufunxa isandi. Ukongezelela, kwindawo efumileyo, izinto eziqhelekileyo zokufunxa isandi zifunxa ukufuma kwaye zandise, kwaye i-coefficient yokufunxa isandi iyancitshiswa kakhulu, ngelixa i-foam ye-aluminium ingathathi ukufuma, kwaye isantya sokufunxa isandi sayo asincitshiswa.
Njengoko ubukhulu bomaleko womoya bunyuka ukusuka kwi-0mm ukuya kwi-90mm, i-frequency ephambili yokufunxa isandi iyehla ukusuka kwi-2000Hz ukuya malunga ne-300Hz. Xa ubungqingqwa bomaleko womoya yi-10, 30, 60, 90mm, isantya esiphambili sokufunxa isandi simalunga ne-1000Hz, 500Hz, 400Hz, 300Hz ngokulandelelanayo. Ngokutsho ingxolo unikezelo unikezelo loyilo isantya ugwebu isandi sokufunxa ipleyiti emva kobunzima umaleko womoya. Eyona ngxolo iphambili eyenziwa ziimoto kuhola wendlela, itonela esezantsi komlambo kunye netonela yangaphantsi kwamanzi ijikeleze i-400Hz, ingxolo ephantsi yomsindo, ngoko ke umaleko womoya we-60mm ubukhulu ubekwe emva kwepleyiti ye-aluminium ye-acoustic ye-foam yesithintelo sesandi sendlela, ezantsi komlambo kunye Itonela ye-acoustic yangaphantsi kwamanzi, enesiphumo esihle sokunciphisa ingxolo. Ingxolo yomzila kaloliwe yingxolo ephakathi-phezulu ngaphezulu kwe-1000Hz, kwaye umaleko womoya oshinyeneyo ongama-20mm ubekwe emva kwephaneli ye-aluminiyam yogwebu efunxa isandi, enesiphumo esihle sokunciphisa ingxolo.
