Hana ʻia nā panela alumini paʻa paʻa i loko o nā panela hoʻoheheʻe kani kiʻekiʻe ma hope o ka hoʻomaʻamaʻa perforation (Φ2mm holes, perforation rate o 1-3%), nona ka hoʻokō kani maikaʻi loa, a hiki i ka 60% ke kani kani. i 90%. No ka mea, ʻaʻohe mokulele o ka ʻili o kēia mea, ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka leo diffuse reflection sound absorption, a i ka manawa like, loaʻa iā ia ka hana hoʻoheheʻe leo o ka Helmholtz resonance acoustic absorber perforated, e hōʻoiaʻiʻo ana i ka helu hoʻoheheʻe kani kiʻekiʻe. Eia kekahi, i loko o ke kaiapuni haʻahaʻa, hoʻopili nā mea acoustic maʻamau i ka wai a hoʻonui ʻia, hoʻemi nui ʻia ka coefficient absorption leo, ʻoiai ʻaʻole e komo ka mea alumini foam i ka wai, ʻaʻole i emi ka nui o ke kani kani.

Aluminum foam pā ma hope o ka hoʻonohonoho ʻana o ka mānoanoa like ʻole o ka pae ea, ʻokoʻa ke alapine nui o ke kani ʻana o ka leo, me ka mānoanoa o ka papa ea mai 0mm a 90mm, ʻo ke alapine nui o ke kani kani mai 2000Hz a hiki i 300Hz a pēlā paha. Ke 10, 30, 60, 90mm ka mānoanoa o ka pae ea, ʻo ka nui o ka nui o ka nui o ka hoʻoheheʻe ʻana o ke kani he 1000Hz, 500Hz, 400Hz, 300Hz a pēlā paha. E like me ka noise frequency distribution design foam rate acoustic panel ma hope o ka mānoanoa o ka ea. Alanui, lalo o ka muliwai, a me lalo o ke kai a me na kaʻa i hana i ka leo nui ma kahi o 400Hz, no ka haʻahaʻa-frequency ka leo, no laila, ke ala keakea leo ala, ma lalo o ka muliwai a me lalo o ke kai tunnels kani-absorbing wall alumina foam acoustic panels ma hope o ka hoonoho ana o ka 60mm mānoanoa o ka ea, maikaʻi ka hopena hoʻohaʻahaʻa leo. ʻO ka walaʻau kaʻaahi ka leo haʻahaʻa a me ke alapine kiʻekiʻe ma luna o 1000Hz, 20mm ka mānoanoa o ka ea i hoʻonohonoho ʻia ma hope o ka pā alumini hoʻoheheʻe kani me ka hopena hoʻemi maikaʻi.

Nā ʻano huahana:
Māmā: 0.25g/cm3～0.75g/cm3;
Ka helu ʻole: 75%～90%;
Ka ikehu absorption: 8J/m3 ~ 30J/m3;
Ka ikaika compressive: 3Mpa ~ 17Mpa;
Ka ikaika wiliwili: 3Mpa～15Mpa;
Aperture: puʻunaue like ʻia 1-10mm, puka nui 4-8mm;
ʻAʻole wela ka hana pale ahi, ʻaʻole hana i nā kinoea ʻona;
ʻO ke kūpaʻa kino, ke ola lōʻihi.
Hua'ōlelo kiko'ī: 1200mm * 600mm * H a iʻole ka hana maʻamau e like me nā koi o ka mea kūʻai.
