Hiki paha iāʻoe keʻike i ka hōʻailona huahana i kohoʻia, aiʻole paha i lohe a heluhelu paha i kahi kūkākūkā e pili ana i ka ratio o ka leo-leo. Hoʻohālikelike pinepineʻia e like me SNR a iʻole S / N, hiki keʻike i kēia cryptic i ka mea kūʻai maʻamau. ʻOiai ka pākuhi ma hope o ka ratio-noise-noise is technical,ʻaʻole ka manaʻo, a hiki i kēia helu ke hoʻopō i ka maikaʻi o ke kani o ke'ōnaehana.
Ho'ōkākaʻia ka hōʻike hōʻailona hōʻailona
Hoʻohālikelike kahi kīhā kani-leo i ka laulā o ke kaha hōʻailona i kahi kiʻekiʻe o ka walaʻau kani. Ua hōʻike pinepineʻia e like me ke ana o decibels (dB) . ʻO ka nui o nā helu i kēlā me kēiaʻano he kūlana maikaʻi loa, no ka mea,ʻoi aku kaʻike kūpono (ka hōʻailona) ma mua o kaʻikeʻana i nāʻikepili (ka leo).
Eia kekahi laʻana, i ka manawa e hoʻonohonoho ai kahi leo leo i ka lakene kani-a-noise i 100 dB,ʻo ia hoʻi,ʻo ka kiʻekiʻe o ka hōʻailona leo he 100 dB ka kiʻekiʻe ma mua o ke kiʻekiʻe o ka leo. ʻO ka hoʻonuiʻana o ka hōʻailona hōhonu o 100 dB heʻoi aku ka maikaʻi ma mua o hoʻokahi i 70 dB (aiʻole ka liʻiliʻi).
No ka hōʻailona, e'ōlelo mākou e kamaʻilio anaʻoe me kekahi ma kahi kīʻaha e ulu ana i kahi kīʻaha nui loa. E'ōlelo pūʻia hoʻi ka hana a ka pahu fri i 50 dB o hum (e nānā i kēia he kani) no ka mea e mālama ana i nā mea i loko o ka mea hauʻoli-he poho hauʻoli nui. Inā koho ka mea āu e kamaʻilio nei e kamaʻilio me ka hawanawana (e noʻonoʻo i kēia me he hōʻailona) ma 30 dB,ʻaʻoleʻoe e hiki ke lohe i kahi hua'ōlelo no ka mea, ua hoʻopauʻia e ka uila refrigerator! No laila, ke noi neiʻoe i ka mea e'ōlelo ikaika, akā ma 60 dB, hiki paha iāʻoe ke noi hou iā lākou e hana hou. ʻO ka'ōleloʻana i 90 dB me ka mea e like me ka hoʻokaniʻana, akāʻo ka liʻiliʻi o nā hua'ōlelo e hoʻomaopopoʻia a hoʻomaopopoʻia. ʻO ia ka manaʻo ma hope o ka ratio o ka leo-kani.
No ke aha he mea nui ke kumu hōʻailona hōʻailona
Hoʻohālikelike no ka lākiō kani-kani i nā hua a me nā'āpana e pili ana i nā leo e like me ka mea'ōlelo, kelepona (keleponaʻole aiʻole), nā pepeiao pepeiao, microphones, nā mea hoʻokanui , nā mea e loaʻa ai, nā kuhi, nā radios, CD / DVD / Nā pāleka maikaʻi PC, nā smartphones, nā papa, a me nā mea hou aʻe. Eia naʻe,ʻaʻole nā mea hana hana a pau e hoʻomaopopo koke i kēia kumukūʻai.
ʻO ke kani maoli i keʻano he keʻokeʻo a iʻole he leka uila aiʻole heʻulaʻula, aiʻole he haʻahaʻa haʻahaʻa a haʻahaʻa paha. Eʻike i ka nui o kāu mau'ōlelo'ōlelo e piʻi loa i ka wā eʻole e pāʻani ana kekahi mea - inā loheʻoe i kāna kani,ʻo ia ka walaʻau, aʻo ka manawa i kapaʻia he "papa haʻahaʻa." E like me ka refrigerator i ka hōʻike i hōʻike muaʻia, aia mau kēia papa walaʻau ma laila.
I ka lōʻihi o ka hōʻailona hōʻailona aʻoi aʻe ma luna o ka papa haʻahaʻa, e hiki i kaʻoni ke mālama i kahi kiʻekiʻe. ʻO ia keʻano o ka maikaʻi o ka leo-leo-noise e makemake ai nā kānaka no ke kani pololei a pololei.
Akā inā i nāwaliwali ka hōʻailona, hiki i kekahi ke manaʻo e hoʻonui i ka leo i mea e hoʻonui ai i ka huahana. Akā,ʻo ka hoʻololiʻana i ka leo i lalo a me lalo pili i ka papa haʻahaʻa a me ka hōʻailona. Hiki ke kani ka leo o ke mele, akā pēlā nō ka leo haʻahaʻa. Ponoʻoe e hoʻonui wale i ka ikaika o ka hōʻailona no ka hoʻokōʻana i ka hopena i makemakeʻia. ʻO kekahi mau polokalamu ke nānā aku i nā lako lako a me nāʻenehana software i hoʻohālikelikeʻia no ka hoʻonuiʻana i ka ōkuhi kani-kani.
ʻO ka mea pōʻino,ʻo nā mea a pau, a me nā kaula, e hoʻohui i kahi haʻahaʻa o ka leo i kahi leo leo. ʻO nā meaʻoi aku ka maikaʻi i hanaʻia e mālama i ka papa haʻahaʻa e like me ka hikiʻole i hiki ke hiki ke hoʻonui i ka lakio. Ana nā polokalamu Analog, e like me nā amplifiers a me nā turntables, ma keʻano he lālā haʻahaʻa haʻahaʻa-a-noise ma mua o nā polokalamu kelepona.
He mea pono ke pale i nā huahana me nā'īlio kikowaena hōhonu. Eia naʻe,ʻaʻole e pono ke hoʻohanaʻia ka lākiō hōʻailona me ke kaulike wale nō e ana i ka maikaʻi o nā kani. Pono e noʻonoʻo pono i ka paneʻana o ka māmā a me ka'āpana'āpana .
