I nā lako leo, ua kapa ʻia ka ʻike o ka lako mea hoʻolele leo ʻo ia kona hiki ke hoʻololi i ka uila i ke kani a i ʻole ke kani i ka uila.

Eia nō naʻe, ʻaʻole pili pono ka pae o ka ʻike i nā ʻōnaehana leo home a i ʻole i hoʻopilikia ʻia e ka maikaʻi o ke kani.

ʻAʻole hiki ke manaʻo maʻalahi a nui ʻole paha ʻo ke kiʻekiʻe o ka ʻike o kahi mea ʻōlelo, ʻoi aku ka maikaʻi o ke ʻano o ke kani. ʻOiaʻiʻo, ʻaʻole hiki ke hōʻole pololei ʻia he pono i kahi mea ʻōlelo me ka ʻike haʻahaʻa ke loaʻa ka maikaʻi ʻole o ke kani. ʻO ka maʻamau, ʻo 1 (watt, W) ka mana o ka hōʻailona hoʻokomo o ka mea ʻōlelo. E kau i ka microphone hoʻāʻo 1 mika pololei i mua o ka mea ʻōlelo, a no kahi mea ʻōlelo piha ʻelua ala, e kau i ka microphone ma waenakonu o nā ʻāpana ʻelua o ka mea ʻōlelo. ʻO ka hōʻailona hoʻokomo he hōʻailona walaʻau, a ʻo ka pae kaomi kani i ana ʻia i kēia manawa ʻo ia ka ʻike o ka mea ʻōlelo.

ʻO ka mea haʻiʻōlelo me ka pane alapine ākea he mana hōʻike ikaika, ʻo ke kiʻekiʻe o ka ʻike e maʻalahi ai ke kani ʻana, ʻo ka mana kiʻekiʻe e paʻa a palekana, me nā piʻo kaulike a me ka pilina pae kūpono a kūpono, ʻaʻole e hoʻopilikia ma muli o ka hoʻohana ʻana i ka ikehu kūloko. No laila, hiki iā ia ke hana hou i nā leo like ʻole, a he manaʻo koʻikoʻi ko ke kani, ka hoʻokaʻawale maikaʻi, ka ʻālohilohi, ka maopopo, a me ka palupalu. ʻO ka mea haʻiʻōlelo me ke kiʻekiʻe o ka ʻike a me ka mana kiʻekiʻe, ʻaʻole wale ia he maʻalahi ke kani, akā ʻoi aku ka nui, ʻo kona pae kaomi leo kiʻekiʻe loa i loko o kahi pae kūlana paʻa a palekana hiki ke "luku i ka lehulehu", a hiki ke loaʻa ka pae kaomi leo i koi ʻia me ka ʻole o ka nui o ka mana e hoʻokele ai.

ʻOi aku ka maikaʻi o ke kiʻekiʻe o ka ʻike o ka ʻōnaehana leo, a ʻoi aku paha ka maikaʻi o ka haʻahaʻa?

ʻO ke kiʻekiʻe o ka ʻike, ʻo ka maikaʻi. ʻO ke kiʻekiʻe o ka ʻike o ka mea ʻōlelo, ʻo ke kiʻekiʻe o ke kaomi leo o ka mea ʻōlelo ma lalo o ka mana like, a ʻo ka leo nui o ke kani i hoʻopuka ʻia e ka mea ʻōlelo. ʻO ka pae kaomi leo i hana ʻia e ka hāmeʻa ma kahi kūlana ma kahi pae hoʻokomo (mana). Pae kaomi leo = 10 * log mana + ʻike.

ʻO ke kumu, no kēlā me kēia pāpālua o ka pae kaomi leo, piʻi ka pae kaomi leo ma 1dB, akā no kēlā me kēia 1dB piʻi ʻana o ka ʻike, hiki ke piʻi ka pae kaomi leo ma 1dB. Mai kēia, hiki ke ʻike ʻia ke koʻikoʻi o ka ʻike. I loko o ka ʻoihana leo ʻoihana, ua manaʻo ʻia ʻo 87dB (2.83V/1m) he palena haʻahaʻa a no nā mea ʻōlelo liʻiliʻi (5 ʻīniha). ʻOi aku ka ʻike o nā mea ʻōlelo maikaʻi ma mua o 90dB, a hiki i kekahi ke piʻi ma luna o 110. Ma ke ʻano laulā, ʻo ka nui o ka nui o ka mea ʻōlelo, ʻoi aku ka kiʻekiʻe o ka ʻike.
