ʻO ka nui o ka hoʻohaʻahaʻa haʻahaʻa leo o ka mea hou alumini foam mea i hiki i ka 0.75, a me ke kani absorption coefficient i ka waena waena o 250 ~ 1000Hz i ʻoi aku ma mua o 0.9, ʻoi aku ma mua o nā mea kani-absorption maʻamau e like me ka huluhulu pōhaku, ka papa gypsum. , pā metala perforated, etc. ʻO kona hiki ke hoʻohaʻahaʻa i ka leo a me ka polyurethane huʻahua. He 7-10 mau manawa ia o ka plastik, ke aniani aniani a me ka alumini honeycomb, a ua kokoke kona insulation kani i 30dB ke hoʻohana ʻia i nā kaʻa kaʻa kiʻekiʻe a me nā panela pahu kaʻa. Hoʻohana ʻia ka mea hoʻoheheʻe alumini hou i nā māla hou aʻe no ka hoʻonui ʻana i ka leo a me ka hoʻohaʻahaʻa ʻana i ka leo a me nā waiwai e pili ana, ʻoi aku ka nui ma nā pale kani ala nui, ka hoʻohaʻahaʻa ʻana o ke alahele alahele, ka hoʻohaʻahaʻa ʻana o ka leo submarine, nā puka makani; ka leo o ka paia o na loko wai; ʻO nā mea alumini foam hou e hana ai i ke kūkulu ʻana i nā leo kani, e like me nā studio hoʻopaʻa leo, nā lumi dubbing, nā keʻena ʻaha mele, nā keʻena kūkā, nā kahua pāʻani, etc.
ʻO nā kumu nui e pili ana i ke kani kani a me ka hopena hoʻohaʻahaʻa leo o nā mea alumini foam hou penei:
1. He mea porous ka mea alumini foam hou, a ʻoi aku ka ʻike o kāna hana hoʻokō kani no ke kani alapine kiʻekiʻe, ʻo ia hoʻi, ʻoi aku ka nui o ka coefficient absorption leo i ka ʻāina kiʻekiʻe. Eia naʻe, ʻaʻole maikaʻi loa ka hopena o ke kani ʻana o ke kani alapine haʻahaʻa, no laila, liʻiliʻi ka coefficient absorption leo ma ka ʻāpana alapine haʻahaʻa;
2. ʻOkoʻa ka mānoanoa o ka pā kani kani i hana ʻia i ka mea alumini foam hou, a ʻokoʻa ke alapine kani. Ke piʻi aʻe ka mānoanoa, e hoʻomohala ʻia ke alapine hoʻoheheʻe kani i ke ʻano o ka hoʻopaʻa ʻana i ke alapine haʻahaʻa. Eia nō naʻe, inā ʻoi aku ka nui o ke kani ma mua o 500Hz, ʻaʻohe mea pili i ka mānoanoa o ka coefficient absorption leo o ka mea alumini foam hou;
3. Ke piʻi aʻe ka mānoanoa o ka mea hou alumini foam mea, ka leo absorption alapine (frequency frequency) i keia manawa e hoʻomōhala i ka haʻahaʻa-frequency kani, a me ka nui a me ka nui o na pores o ka mea hou alumini pahupahu mea no hoi i maopopo okoa i ke kani. ka hoʻokō ʻana o ka pā leo.
No ka maʻalahi, ʻo nā koho like ʻole o nā mea hoʻoheheʻe alumini hou, e like me ka mānoanoa, density, porosity, a me nā mea ʻē aʻe, e hopena i nā hopena leo like ʻole. No ke ʻano o ke koho ʻia ʻana o nā mea pahu alumini hou, ʻoi aku ka maikaʻi e kūpono i ko lākou kūlana ponoʻī.
