ʻO ka pā ʻūhā alumini he aniani hiʻohiʻona i hui pū ʻia i ka leo hoʻoheheʻe leo. Hoʻohana mau ʻia ka pahu kani alumini ma Kina, ʻo ke kumu kūʻai no ka mika laina ma kahi o 2,250 yuan (8 mm mānoanoa o ka pahu alumini, ʻaʻole ke kumu). Loaʻa iā ia nā hiʻohiʻona koʻikoʻi a me nā pono:
(1)ʻO nā paneli hoʻopaʻa leo aluminiʻike pololei ʻia i ka lewa, me ka ʻole o ka pono o nā panela perforated a me nā mea hoʻopihapiha, a me nā mea ʻē aʻe, a maʻalahi ke hoʻokomo. ʻO ka panel acoustic foam alumini ka mea pani o ka honua non-fiber acoustic huahana, ʻaʻole e like me ka hulu hipa aniani a me nā mea maʻalahi e hoʻoheheʻe ʻia ma hope o ka hopena o ka hana acoustic, a ʻaʻole e ʻelemakule ma muli o ka lepo a me ka microfiber dispersal o ke kaiapuni i hoʻokumu ʻia. e ka pollution lua.
(2)Aluminum pahu kani paleua paʻa acoustic hana, ka awelika absorption coefficient ua oi aku mamua o 0.64, leo hoemi coefficient NRC0.75 a pela aku, no ka haʻahaʻa-frequency-ma muli kaʻa kaʻa acoustic hana maikai, 125Hz absorption coefficient o 0.52, 250 Hz absorption coefficient. 500 Hz no 0.92, ʻoi aku ka kiʻekiʻe ma mua o kekahi mau mea acoustic maʻamau i hoʻohana ʻia, a i ka ua a me ka absorption o ka lepo, ʻaʻole e loli ka coefficient absorption. ʻAʻole e loli ka helu hoʻoheheʻe kani, a hoʻokō ka hōʻike hoʻāʻo i nā koi acoustic o nā pale kani alanui.

(3) Hiki ke hoʻokuʻu ʻia nā panela acoustic foam alumini i nā ʻano kala like ʻole, a ʻaʻole pili ka hana acoustic.
(4) Hiki ke holoi ʻia ka panel acoustic foam alumini e like me ke aniani, a hiki ke hoʻomaʻemaʻe iā ia iho ma o ka ua maoli, ʻaʻole ia e pili i ka hana acoustic; ma hope o ka hōʻiliʻili ʻana o ka lehu, ʻaʻole wale ia e pili i ka hana acoustic, akā hoʻomaikaʻi pū i ka hana acoustic kiʻekiʻe.
(5) Loaʻa ka pahu alumini i ke ahi e pili ana i ke ahi, ka pale ʻana i ka wā, ka pale ʻana i ka corrosion, ka pale ʻana i ka wā kahiko, ke ola lawelawe hoʻolālā o 20 mau makahiki, haki a hou ʻia.nā panela pahu aluminihiki ke hana hou i na mea a pau.
(6) ʻO nā panela acoustic foam alumini i hoʻohālikelike ʻia me ka fiberboard alumini he mau hiʻohiʻona anti-glare maikaʻi, ʻoi aku hoʻi i ka pō a me nā lā ua, hiki ke hoʻopau i nā pōʻino palekana.
