ʻO ka pahu alumini mea hou mea hoʻohaʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a hiki i ka 0.75, 250 ~ 1000Hz medium frequency band sound absorption coefficient i ʻoi aku ma mua o 0.9, ʻoi aku ka nui ma mua o ka huluhulu pōhaku, ka papa gypsum, ka pā metala perforated a me nā mea kani-absorption maʻamau. ʻO ka hoʻohaʻahaʻa piha ʻana o ka polyurethane foam, aniani fiber, honeycomb aluminika 7-10 nā manawa, i hoʻohana ʻia i nā kaʻaahi kiʻekiʻe, ka pahu pahu kaʻa kona nui insulation kani kokoke i 30dB. alumini foam mea hou Me kona oi aku ka leo absorption a me ka leo hoemi a me ka pili ana hana i hoʻohana 'ia i loko o ka nui a me ka oi mau kahua, ka nui o ka noonoo ana i ke ala keakea leo, alaloa tunnel ka leo hoemi, submarine tunnel hoemi ana, tunnel vent; pā acoustic o ka wai ʻauʻau; alumini foam mea hou e hana ana i ka hale acoustic lining, e like me ka lumi hoʻopaʻa leo, dubbing lumi, hale ʻaha mele, hale hālāwai, ke kahua pāʻani, etc.

ʻO nā kumu kumu nui o ka hoʻoheheʻe ʻana i ke kani a me ka hopena hoʻohaʻahaʻa leo o ka alumini foam mea hou e like me kēia.
1, alumini pahu hou mea no ka porous mea, kona kani absorption hana no kiʻekiʻe alapine (frequency leo) ua oi akaka, 'o ia hoʻi, i loko o ke alapinepine wahi absorption coefficient nui. A no ka haʻahaʻa alapine kani absorption hopena ʻaʻole kūpono loa, no laila ma ka haʻahaʻa haʻahaʻa ʻāpana absorption coefficient liʻiliʻi.
2, foam alumini mea hou i hanaia me ka leo-absorpning panels mea manoanoa mea, ka leo absorption alapine 'aʻole like, ka mānoanoa o ka hoonui, ka alapine o ka leo absorption e e komo haʻahaʻa alapine alapine. Eia nō naʻe, inā ʻoi aku ka nui o ke kani ma mua o 500Hz, i kēia manawa ʻaʻohe mea pili i ka mānoanoa o ka coefficient absorption leo o ka alumini foam mea hou.
3, i ka wā e hoʻonui ai ka nui o ka alumini foam mea hou, i kēia manawa e hoʻomohala ʻia ke alapine o ke kani ʻana i ke kani haʻahaʻa haʻahaʻa, a me ka nui o nā pores o ka alumini foam mea hou, pehea ka nui o ka hoʻokō kani ʻana o ke kani-absorpning. He ʻano ʻokoʻa loa ka panel.
I ka pōkole, ʻokoʻa ka koho ʻana o ka alumini foam mea hou, e like me ka mānoanoa, density, pores a me nā mea ʻē aʻe, e noʻonoʻo ana i ka hopena o ka hoʻoheheʻe ʻana o ke kani e ʻokoʻa, ʻaʻohe mea pehea e koho ai i ka alumini foam mea hou, kūpono i ko lākou kūlana ponoʻī. pono.
