I-aluminiyam igwebu lezinto ezintsha ezibanzi zokunciphisa ingxolo i-coefficient ye-0.75, 250 ~ 1000Hz medium frequency band isandi sokufunxa isandi sifikelela ngaphezu kwe-0.9, ngaphezu koboya belitye, ibhodi yegypsum, ipleyiti yentsimbi enemingxuma kunye nezinye izinto eziqhelekileyo zokufunxa isandi, ukugqunywa kwesandi kunye nengxolo. Ukunciphisa amandla abanzi yi-polyurethane foam, ifayibha yeglasi, i-honeycomb I-aluminiyam ngamaxesha angama-7-10, isetyenziswe koololiwe abahamba ngesantya esiphezulu, ipleyiti yebhokisi yemoto isixa saso sokufakelwa kwesandi sisondele kwi-30dB. i-aluminiyam ye-foam imathiriyeli entsha Ngokufunxa isandi sayo esiphezulu kunye nokunciphisa ingxolo kunye nokusebenza okuhambelanayo kusetyenziswa kwiinkalo ezininzi nangakumbi, ikakhulu zigxininiswe kwisithintelo sesandi sohola wendlela, ukunciphisa ingxolo yetonela yendlela, ukunciphisa ingxolo yetonela, i-tunnel vent; udonga lwe-acoustic lwe-swimming pool; i-aluminium amagwebu amagwebu amatsha okwenza ulwakhiwo lwe-acoustic, olufana negumbi lokurekhoda, igumbi lokudlala, iholo yekonsathi, iholo yenkomfa, ibala lezemidlalo, njl.

Imiba ephambili enempembelelo yokufunxa isandi kunye nesiphumo sokunciphisa ingxolo yezinto ezintsha ze-aluminium foam zilandelayo.
I-1, i-aluminiyam i-foam imathiriyeli entsha yeyemathiriyeli ye-porous, isandi sayo sokufunxa isandi sesandi esiphakamileyo sicace ngakumbi, oko kukuthi, kwindawo ephezulu yokufunxa i-coefficient enkulu. Kwaye isiphumo sokufunxa isandi esisezantsi asilunganga kakhulu, ke ngoko kwingingqi ephantsi i-coefficient yokufunxa incinci.
I-2, i-aluminiyam ye-foam imathiriyeli entsha eyenziwe ngeepaneli ezifunxa isandi ubukhulu bezinto zahlukile, i-frequency yokufunxa isandi ayifani, ubukhulu bokwanda, ukuphindaphinda kokufunxa isandi kuya kuba kukutsala umkhombandlela ophantsi. Nangona kunjalo, xa i-frequency yesandi ingaphezulu kwe-500Hz, ngeli xesha i-coefficient yokufunxa isandi se-aluminium foam entsha ayinanto yakwenza nobukhulu.
3, xa ingxinano ye-aluminiyam ye-foam entsha isanda, ngeli xesha ukuphindaphinda kokufunxa kwesandi kuya kukhula ukuya kwisandi esiphantsi rhoqo, kunye nobukhulu bemibhobho ye-aluminium amagwebu enziwe ngezinto ezintsha, ingakanani isandi sokufunxa isandi sokufunxa isandi. indawo yolawulo inombonakaliso owahlukileyo kakhulu.
Ngamafutshane, ukhetho aluminiyam amagwebu izinto ezintsha yahlukile, ezifana ubukhulu, ingxinano, pores kunye nezinye ezahlukeneyo, ebonisa isiphumo ukufunxa isandi iya kwahluka, kungakhathaliseki ukuba ukhethe aluminiyam amagwebu izinto ezintsha, kufanelekile imeko yabo ngakumbi. esebenzayo.
