Mea loiloi walaʻau ma lalo o ka wai ʻo UNAS
ʻO ka UNAS Underwater Noise Analyzer kahi ʻōnaehana manawa maoli no ka nānā ʻana a me ka hoʻoili ʻana i ka walaʻau o lalo o ka wai. Ke kūkulu nei ma luna o nā ikaika koʻikoʻi i ka hoʻohana ʻana i ka mana haʻahaʻa a me ka walaʻau kūloko haʻahaʻa, kākoʻo ia i nā ʻano hana ʻelua: ka hoʻopaʻa leo kūʻokoʻa a me ka hoʻoili pūnaewele manawa maoli. Me kahi hoʻolālā liʻiliʻi a māmā hoʻi, hiki ke hoʻolaha ʻia ka hāmeʻa ma nā buoys, nā kahua papahele kai, a i ʻole nā kahua nānā kelepona. Ua lako me kahi pākahiko hiki ke hoʻouka hou ʻia i kūkulu ʻia e hāʻawi ana i kahi ahonui kūʻokoʻa o≥48 mau hola; a i ʻole, hiki ke hoʻoikaika ʻia e ka paepae kikowaena no ka nānā ʻana ma ka pūnaewele no ka manawa lōʻihi, e hoʻouna ana i ka ʻikepili walaʻau manawa maoli a me ka ʻike spectral ma o Ethernet a i ʻole RS485 interfaces.
Hiki i nā ʻāpana he nui ke hoʻohana i ka uaki o ka paepae kikowaena e hoʻomaʻamaʻa i nā nānā i hoʻolaha ʻia a hoʻonohonoho ʻia me ka pololei o ka synchronization ma mua o 1.μs. Hoʻohana nui ʻia ka ʻōnaehana ma nā kahua e like me ka nānā ʻana i ka walaʻau kai ma ka pūnaewele, ka nānā ʻana i nā mammals kai, a me ka loiloi walaʻau ʻenekinia ma lalo o ka wai, a loaʻa i nā mana i hana kūikawā ʻia no nā wahi kai a me ke kai hohonu.

ʻO ka pūʻulu Hydrophone ponoʻī a Smurf
He hydrophone kikohoʻe kai hohonu ʻo Smurf i hoʻolālā ʻia ma luna o kahi kahua mana haʻahaʻa loa. He liʻiliʻi a lawe lima loa, hiki iā ia ke loaʻa pololei o nā hōʻailona leo wai ma lalo o ka wai a kākoʻo i ka hana kūʻokoʻa lōʻihi. Loaʻa i ka hāmeʻa kahi interface USB wikiwiki no ka hoʻopili pololei ʻana i kahi kamepiula, e ʻae ana i ka loaʻa ʻana o ka ʻikepili me ka ʻole o ka pono e wehe i ka hale. Kākoʻo ia i nā hoʻonohonoho array i hoʻonohonoho ʻia ma ke kaula, hiki ke hoʻonui ʻia a hiki i 128 mau mea, me ka pololei o ka synchronization ma mua o 1.μs—e hōʻoia ana ʻaʻole e hōʻiliʻili nā hewa manawa i ka hala ʻana o ka manawa.
Me nā pae walaʻau ponoʻī haʻahaʻa ma mua o Sea State 0, ua hana ʻia kona ʻano titanium alloy kūʻē i ke kaomi no nā wahi kai hohonu a hiki i 6,000 mika. Hoʻolaha nui ʻia i nā anamanaʻo acoustic moana, ka noiʻi ʻepekema kai hohonu, ka bio-tracking, ka nānā ʻana i ka walaʻau kaiapuni, a me nā nānā ʻana i nā puka nui, kū ʻo Smurf ma ke koho mua no ka nānā ʻana i nā leo acoustic kai hohonu lawe lima.

Mea Hoʻopaʻa Leo Leo LoPAS-L Mana Haʻahaʻa Loa
ʻO ka moʻo LoPAS he mau mea ʻike leo wai haʻahaʻa loa, nona iho. Me nā modula hana hōʻailona walaʻau haʻahaʻa i hoʻokomo ʻia a me ka hoʻohana ʻana i ka ʻenehana ʻike piezoelectric, hiki i kēia mau mea ke loaʻa i ka manawa like o nā hōʻailona leo wai a me ka ʻikepili hohonu/mahana, a me ka hoʻopaʻa leo ʻana no ka manawa lōʻihi. ʻO nā mea hana'ʻOi aku ka haʻahaʻa o nā pae walaʻau ponoʻī ma mua o nā kūlana o Sea State 0; eia kekahi, ʻo kā lākou hoʻolālā mana haʻahaʻa loa e hōʻoiaʻiʻo ana i ka hoʻomanawanui hana paʻa a hilinaʻi hoʻi. Kākoʻo ka moʻo i ka hoʻolaha ʻana o nā ʻano hana he nui i hoʻonohonoho ʻia—ka hoʻokō ʻana i ka pololei o ka synchronization ma mua o 1μs—me nā puka ākea i hiki ke uhi i ka hohonu piha o ke kai.
Hoʻohana ka moʻo LoPAS i kahi ʻano hoʻopaʻa honua, e ʻae ana i ka hoʻohui maʻalahi ʻana i nā kahua like ʻole e like me nā moorings subsurface, buoys, a me nā kikowaena nānā ma waho. Hoʻohana nui ʻia ia ma nā kahua e like me nā anamanaʻo leo moana, ka noiʻi ʻepekema ma waho, ka bio-tracking, ka nānā ʻana i ka walaʻau o ka mahiʻai makani, a me nā loiloi hopena kaiapuni ma lalo o ka wai.

Nānā Walaʻau Infrasonic ARMS
ʻO ka ARMS Underwater Acoustic Noise Monitor kahi mea nānā walaʻau ma lalo o ka wai i hoʻomohala kūʻokoʻa ʻia e Haiyan Electronics. He mea hopu hōʻailona leo i hoʻohui ʻia i hoʻolālā ʻia no nā noi e like me ka nānā ʻana i ka leo leo moana, ka ʻimi ʻepekema ma lalo o ka wai, a me ke ana ʻana i ka walaʻau ma lalo o ka wai. Loaʻa i ka huahana nā pono koʻikoʻi e pili ana i kahi laulā pane alapine ākea o 10 Hz a 10 kHz, ka walaʻau ponoʻī haʻahaʻa like, a me ka ʻike kiʻekiʻe. Ma ka hoʻohana ʻana i kahi hoʻolālā hoʻohui ponoʻī, hiki iā ia ke hana kūʻokoʻa i ka loaʻa ʻana a me ka mālama ʻana i nā hōʻailona leo leo ma lalo o ka wai me ka ʻole o ka pono no nā lako hopu waho paʻakikī.
Me kāna hana paʻa a me nā ana pololei, lawelawe ka ARMS Underwater Acoustic Noise Monitor ma ke ʻano he mea hana kūikawā kūpono no ka nānā ʻana i ke kaiapuni kai, nā ana ʻenekinia ma lalo o ka wai, a me ka noiʻi kai acoustic.
