Me ka ulu wikiwikiʻana o kaʻoihanaʻoihana, ua hana nā kānaka i kahi pūʻulu hou o "nā leoʻoihana" me nā leo o keʻano. ʻO ka pukaʻana o "nā leoʻoihana" e hōʻoiaʻiʻo i nā kapuaʻi o ka hoʻomohalaʻoihana. Eia naʻe, i ka hoʻomohala ʻana o "nā leo ʻoihana" , inevitably haʻalele i kahi "kino" - walaʻau, no laila ua hoʻomaka ke kaua pale "noise".
I kēia manawa, nā mea kani-absorbing a me ka walaʻau-ho'ēmi mea ma ka makeke komo polyester pulupulu, aniani hulu hipa, polyurethane pahupahu, inorganic pahu metala mea, etc. E like me ka inorganic pahu metala mea me ka maikaʻi loa koina hana a me ka hana, kona piha leo. ʻO ka hiki ke hoʻohaʻahaʻa a me ka hoʻohaʻahaʻa leo he 7-10 mau manawa o ka polyurethane foam, ke aniani aniani, a me ka alumini honeycomb. Ke hoʻohana ʻia i nā kaʻaahi kiʻekiʻe a me nā panela pahu kaʻa, kokoke ke kani ʻana o ke kani i 30dB. Wahi a ka ʻikepili hoʻāʻo, hiki ke hoʻemi ʻia ke kiʻekiʻe insulation leo o nā pale kani maʻamau e 5dB, a hiki ke hoʻemi ʻia ka mea alumini foam e 10-20dB.
Me ka hoʻomohala ʻana o ka alumini foam industrialization, hoʻohana ʻia ka foam alumini i nā ʻano he nui a ʻoi aku ka maikaʻi o ke kani ʻana o ke kani a me ka hoʻohaʻahaʻa leo a me nā waiwai e pili ana, ʻo ia hoʻi i nā pale kani alaloa, ka hoʻohaʻahaʻa ʻana i ke kani o ke alaloa, ka hoʻohaʻahaʻa ʻana i ka leo submarine, a me ka ea. ʻO nā paia kani o nā loko ʻauʻau; ka hoʻonani o loko o nā wahi hoʻokipa; nā papahele hoʻoheheʻe leo alumini; ka hana ʻana o nā kaʻa kaʻa, nā kaʻa kaʻa a me nā muffler kaʻa; ʻO ka hana alumini foam o ke kūkulu ʻana i nā linings hoʻopaʻa leo, e like me nā keʻena hoʻopaʻa leo, nā lumi dubbing, nā hale ʻaha mele, nā keʻena kūkā, nā kahua pāʻani, etc.
