Me ka ulu wikiwiki ʻana o ka nohona kanaka, nui aʻe nā pono waiwai a me ka ʻuhane o ka poʻe, a ke ʻimi nei i ka home ʻoluʻolu loa. No laila, kūʻai nā kānaka i nā stereo kiʻekiʻe, me ka manaʻo e hauʻoli i nā mele ma ka home; kūʻai i nā projectors, me ka manaʻo e nānā i nā kiʻiʻoniʻoni ma kahi moe; kūʻai i nā wili, me ka manaʻolana e hoʻoikaika kino me ka haʻalele ʻole i ka home. I ka neʻe ʻana o nā kānaka i nā mea hana hou aʻe i loko o ko lākou mau home, hoʻokumu ʻia ka pilikia nui loa - ka walaʻau. No laila, ua hoʻomaka ke kaua pale "noise".
I kēia manawa, ʻo nā mea kani maʻamau a me ka hoʻohaʻahaʻa ʻana i ka leo ma ka mākeke e pili ana i ka fiber polyester, ka hulu aniani, ka polyurethane foam, a me nā mea metala foam. E like me ke kumu kūʻai nui a me ka hana-friendly alumini foam mea i loko o kona papa, kona piha leo insulation a me ka leo hoemi hiki hiki 7-10 manawa o ka polyurethane foam, aniani fiber, a me ka meli alumini. Ke hoʻohana ʻia i nā kaʻaahi kiʻekiʻe a me nā panela kaʻa, kokoke ka insulation 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. Wahi a ka ho'āʻo, ua hōʻike ʻia:
| Mea waiwai | Hōʻike | Hoʻemi Hoʻoemi Leo / Ka nui o ka hoʻohaʻahaʻa leo |
| ʻO ka pahu polyurethane | 35mm mānoanoa | ʻO 0.85NRC ka helu hoʻohaʻahaʻa leo |
| ʻO ka pahu polyurethane | 35mm mānoanoa | ʻO 23dB ke kani ʻana o ke kani |
| ʻO ka pahu pahu alumini | 20mm mānoanoa | ʻO 0.9NRC ka helu hoʻohaʻahaʻa leo |
| ʻO ka pahu pahu alumini | 20mm mānoanoa | ʻO 30dB ke kani ʻana o ke kani |
Me ka hoʻomohala ʻana o ka alumini foam industrialization, hoʻohana ʻia ka ʻūhā alumini ma nā ʻāina ʻoi aku ka maikaʻi o ke kani ʻana a me ka hoʻohaʻahaʻa ʻana o ka walaʻau a me nā waiwai e pili ana, e like me nā pale kani alanui, ka hoʻohaʻahaʻa ʻana o ke ala ala, ka hoʻohaʻahaʻa ʻana o ka leo submarine, a me nā puka puka; ʻO nā paia kani o nā loko ʻauʻau; ka hoʻonani o loko o nā wahi leʻaleʻa; 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 hale hālāwai, nā wahi haʻuki a me nā kula ʻē aʻe, he hana maikaʻi loa.
