Ngokukhula ngokukhawuleza kwenguqu kwezoshishino, abantu baye benza uluhlu olutsha “lwezandi zamashishini” ukongezelela kwizandi zendalo. Ukuvela "kwezandi zamashishini" kuqinisekisa uphuhliso lwezoshishino. Nangona kunjalo, ekuphuhliseni "izandi zamashishini" , ngokuqinisekileyo ushiye "isiphako" - ingxolo, ngoko ke "ingxolo" idabi elikhuselayo laqala.
Okwangoku, izinto eziqhelekileyo zokufunxa isandi kunye nezixhobo zokunciphisa ingxolo kwimarike ziquka ifayibha yepolyester, uboya beglasi, i-polyurethane foam, imathiriyeli yesinyithi ye-inorganic foam, njl njl. Ukugquma kunye namandla okunciphisa ingxolo ngamaxesha angama-7-10 e-polyurethane foam, i-glass fiber, kunye ne-honeycomb aluminiyam. Xa isetyenziswe koololiwe abahamba ngesantya esiphezulu kunye neepaneli zeebhokisi zemoto, ukugqunywa kwesandi kusondele kwi-30dB. Ngokutsho kwedatha yokuvavanya, inqanaba lokugquma isandi kwizikrini eziqhelekileyo zomsindo zingancitshiswa kuphela nge-5dB, kunye nezinto eziphathekayo ze-aluminium ze-foam zingancitshiswa nge-10-20dB.
Ngophuhliso lwe-aluminiyam ye-foam industrialization, i-aluminiyam i-foam isetyenziswa kwiindawo ezininzi zokufunxa isandi esiphakamileyo kunye nokunciphisa ingxolo kunye neempawu ezihambelanayo, ngokukodwa kwimiqobo yesandi sohola wendlela, ukunciphisa ingxolo ye-tunnel yendlela, ukunciphisa ingxolo ye-submarine, kunye nomoya we-tunnel. Iindonga ezifunxa isandi zamadama okuqubha; umhlobiso wangaphakathi weendawo zokuzonwabisa; i-aluminiyam yogwebu imigangatho yokugquma isandi; ukuveliswa kwe-aluminiyam ye-foam yeelori, iimoto zabahambi kunye ne-mufflers yemoto; ukuveliswa kwe-aluminium ye-foam yokwakhiwa kwe-sound-absorbsorbing linings, ezifana nezitudiyo zokurekhoda, amagumbi okuhlamba, iiholo zekhonsathi, iiholo zeenkomfa, amabala, njl.
