Ipuleti le-aluminium Foam yeseli evaliwe lenziwa libe ipuleti elimunca umsindo eliphezulu elisebenza kahle kakhulu ngemva kokwelashwa kokubhobozwa (φ2mm umgodi, izinga lokubhoboza 1~3%), elinokusebenza okuhle kakhulu kokumuncwa komsindo, futhi izinga lokumunca umsindo lingafinyelela ku-60%~90%. Ngenxa yokuthi ingaphezulu lalokhu kwaziswa alinayo indiza, inomsebenzi omuhle kakhulu wokumunca umsindo ozwakalayo ohlukanisiwe, futhi ngesikhathi esifanayo ine-perforated umsebenzi wokumunca umsindo we-Helmholtz resonance absorber ukuze kuqinisekiswe izinga eliphezulu lokumunca umsindo. Ngaphezu kwalokho, endaweni enomswakama, izinto ezijwayelekile ezimunca umsindo zimunca umswakama futhi zandise, futhi i-coefficient yokumunca umsindo iyancipha kakhulu, kuyilapho impahla ye-aluminium foam ingawumumbi umswakama, futhi izinga lokumunca umsindo walo alincishisiwe.
Njengoba ugqinsi longqimba lomoya lukhula lusuka ku-0mm luye ku-90mm, imvamisa eyinhloko yokumuncwa kwemisindo iyehla isuka ku-2000Hz iye cishe ku-300Hz. Uma ugqinsi longqimba lomoya luyi-10, 30, 60, 90mm, imvamisa eyinhloko yezinga lokumunca umsindo cishe i-1000Hz, 500Hz, 400Hz, 300Hz ngokulandelanayo. Ngokusho komklamo wokusabalalisa imvamisa yomsindo ipuleti lokumunca lomsindo wesilinganiso segwebu ngemuva kogqinsi longqimba lomoya. Imvamisa enkulu yomsindo okhiqizwa izimoto ezisemgwaqeni onguthelawayeka, emhubheni ongaphansi komfula kanye nomhubhe ohamba ngaphansi kolwandle icishe ibe ngu-400Hz, okuwumsindo wefrikhwensi ephansi, ngakho-ke ungqimba lomoya oluwugqinsi oluwu-60mm lusethelwe ngemuva kwepuleti le-aluminium eliyigwebu le-acoustic lesithiyo somgwaqo onguthelawayeka, phansi komfula kanye udonga lwe-acoustic lomhubhe ongaphansi kwamanzi, olunomphumela omuhle wokunciphisa umsindo. Umsindo womzila wesitimela uwumsindo ophakathi nophezulu ongaphezu kuka-1000Hz, futhi ungqimba lomoya oluwugqinsi ongu-20mm lusethwe ngemva kwephaneli emunca umsindo ye-aluminium eyigwebu, enomthelela omuhle wokunciphisa umsindo.
