Motsoako o felletseng oa phokotso ea lerata oa thepa e ncha ea foam ea aluminium e fihla ho 0.75, 'me coefficient ea ho monya molumo bohareng ba maqhubu a 250 ~ 1000Hz e fihla ho feta 0.9, e fetang hole lisebelisoa tse sebelisoang hangata tse monyang molumo joalo ka rock ea rock, gypsum board. , poleiti ea tšepe e nang le perforated, joalo-joalo bokhoni ba ho fokotsa ke polyurethane foam. Ke makhetlo a 7-10 a polasetiki, fiber ea khalase le aluminium ea khekhe ea linotši, 'me molumo oa eona oa molumo o haufi le 30dB ha o sebelisoa litereneng tsa lebelo le holimo le liphanele tsa lebokose la likoloi. Thepa e ncha ea foam ea aluminium e sebelisoa masimong a mangata bakeng sa ho monya molumo o phahameng le ho fokotsa lerata le thepa e amanang le eona, haholo-holo mekoallong ea molumo oa litsela tse kholo, phokotso ea lerata la litseleng tse kholo, phokotso ea lerata ea likepe tse tsamaeang ka tlas'a metsi, likotopo tsa kotopo; molumo oa ho monya leboteng la matamo a ho sesa; thepa e ncha ea aluminium ea foam ho etsa lesela le monyang molumo, joalo ka litsi tsa ho rekota, likamore tsa ho rekota, liholo tsa konsarete, liholo tsa kopano, mabala a lipapali, jj.
Lintlha tse ka sehloohong tse amang ho monya ha molumo le phello ea ho fokotsa lerata ea thepa e ncha ea aluminium ea foam ke tse latelang:
1. Thepa e ncha ea foam ea aluminium ke lisebelisoa tsa porous, 'me ts'ebetso ea eona ea ho monya molumo e totobetse haholoanyane bakeng sa molumo o phahameng oa maqhubu, ke hore, coefficient ea ho monya molumo e kholo sebakeng se phahameng sa maqhubu. Leha ho le joalo, phello ea ho monya molumo oa molumo o tlase oa maqhubu ha o ntle haholo, ka hona, coefficient ea ho monya molumo sebakeng sa maqhubu a tlase e nyane;
2. Botenya ba boto e amohelang molumo e entsoeng ka thepa e ncha ea aluminium ea foam e fapane, 'me maqhubu a nang le molumo a fapane. Ka keketseho ea botenya, maqhubu a khabane a ho monya molumo a tla hola ho lebisa ho monyeng ha maqhubu a tlase. Leha ho le joalo, ha maqhubu a molumo a le kholo ho feta 500Hz, coefficient ea ho monya molumo oa thepa e ncha ea aluminium ea foam ha e amane le botenya;
3. Ha boima ba lisebelisoa tse ncha tsa aluminium bo ntse bo eketseha, molumo o babatsehang oa ho kenngoa ha molumo ka nako ena o tla boela o ntlafatse ho ea ho molumo o tlaase, 'me boholo ba pore le palo ea lisebelisoa tse ncha tsa aluminium le tsona li na le phapang e totobetseng ea ho kenngoa ha molumo. tshebetso ya phanele e monyang modumo.
Ho e beha ka mokhoa o bonolo, likhetho tse fapaneng tsa lisebelisoa tse ncha tsa foam tsa aluminium, joalo ka botenya, letsoalo, porosity, joalo-joalo, li tla fella ka litlamorao tse fapaneng tsa ho monya molumo. Ho sa tsotellehe hore na lisebelisoa tse ncha tsa aluminium foam li khethoa joang, ho sebetsa hantle ho lumellana le boemo ba bona.
