ʻO ka walaʻau i loko o ka hale o ka moku mai nā mīkini diesel. ʻAʻole e hoʻopilikia wale ka walaʻau i loko o ka hale kaʻa a hoʻopau i ka hana hana o nā mea hana a me nā lako ponoʻī o ka moku, akā pili pū kekahi i ka hoʻohana ʻana i nā kelepona a me nā pipeline telephony no ke kamaʻilio ʻana, a inā ʻo ka poʻe i loko o kahi ʻano hana walaʻau ikaika no ka lōʻihi. manawa, e hoʻolohe A e hoʻemi ʻia ka mākaukau hana, e pili ana i ke olakino kino a me ka noʻonoʻo. No nā wahi i hoʻopaʻa ʻia, ʻoi aku ka hopena o ka reverberation i ka walaʻau, a ʻo ka absorption leo a me ka hoʻohaʻahaʻa ʻana i ka walaʻau he ana kūpono ia e hōʻemi pono ai i ka reverberation o ka hale.

ʻO nā mea hoʻoheheʻe leo kuʻuna maʻamau ka mea nui: nā mea fiber organik (e like me ka pulupulu pulupulu, ka lāʻau fiberboard), nā mea fiber inorganic (e like me ka hulu aniani, ka hulu pōhaku), a me nā mea polymer foamed (polyurethane foam, polypropylene foam), akā ʻo kēia mau mea. haʻahaʻa i ka ikaika, palupalu a maʻalahi hoʻi e haki, pōkole ke ola lawelawe, maʻalahi e deliquesce, maʻalahi e lele, a maʻalahi hoʻi e hana i ka pollution lua. Ke noʻonoʻo nei i ke kaiapuni kūikawā ma luna o ka moku a me nā koi olakino o nā limahana, pono e koho ʻia ke kaumaha māmā a me ke kani ʻana o ke kani. ʻOi maikaʻi, pale ahi, pale ʻana i ka lapalapa, hōʻoiaʻiʻo i ka lepo, ʻaʻohe lepo, ʻaʻohe mea ʻawaʻawa, olakino a me nā mea pili i ke kaiapuni. Me ka hoʻomohala ʻana o ka ʻenehana a me ka ʻoihana hana, ua puka mai kahi ʻano mea hoʻoheheʻe leo porous, ʻo ia ka mea i kapa ʻia he mea metala foam.

Hoʻokomo ʻia kahi pahu kani i haku ʻia me ka pahu alumini hoʻoheheʻe ʻia a me ka lua ma hope o ia mea i hoʻokomo ʻia i loko o ka lumi ʻenekini kūloko o ka submarine, hiki ke hoʻemi i ka walaʻau ma mua o 20 decibels, kahi kūpono i ka hana ʻana i nā submarine leo.
ʻO nā moku ʻē aʻe e like me ke alakaʻi ʻana i nā missile luku e pono hoʻi e hoʻohana i nā panela hoʻoheheʻe leo alumini no ka hoʻohaʻahaʻa ʻana i ka walaʻau i loko o ka lumi mīkini a hana i nā pā pā.
Hiki ke hoʻonui i ka ikaika o ka deck ma mua o 2 mau manawa, hiki ke hoʻonui i ka ikaika o ka deck ma mua o 2 mau manawa, ʻo ka hui pū ʻana o nā pā kaua, nā pā alumini foam, a me nā pā kila.

ʻO ka alumini foamed he haʻahaʻa haʻahaʻa, ikaika kiʻekiʻe, pale ʻana i ka corrosion, insulation leo, a me ka non-combustibility. Hoʻohana ʻia i nā mokulele mokulele, nā moku, nā moku kaʻa, nā moku hui ʻia, nā yachts, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia ka alumini foam no ka hana ʻana i nā panela kani, nā keʻena o loko, nā papahele ahi-retardant, nā paipu hoʻopau engine, nā hale niches, etc.
