ʻO ka kani he haʻalulu lākou e hoʻolaha ma waena o ka mea waena. No ke ola o ke kani, pono e loaʻa kekahi mau kumuwaiwai (mea a i ʻole ʻūmia) e hoʻohua iā lākou.
ʻAʻole hoʻolaha ke kani i kahi hakahaka, akā pono i kahi ʻano kino: kinoea, wai a paʻa paha, e like me ka ea a me ka wai, e hoʻolaha.
Kaukaʻi ʻia i ko lākou ikaika (mana acoustic), hiki i nā kani ke nui, no ka laʻana:ka pa ana o ka pu; a palupalu paha, e laʻa me: nā lima o ka uaki. ʻO ka leo nui ke ana i hoʻohana ʻia e ʻoka i nā kani i kahi hierarchy mai ka leo nui a i ka haʻahaʻa.
ʻIke ʻia nā kani e ka pepeiao o ke kanaka ma o ka pono hana lohe e loaʻa nā nalu kani a lawe i ka ʻike i ka lolo. No ka hiki i ka pepeiao o ke kanaka ke ʻike i kahi kani, pono ia e ʻoi aku i ka paepae lohe (0 dB) a ʻaʻole e kiʻi i ka paepae ʻeha (130 dB).
Hoʻololi ka pae o ka pae lohe mai kēlā me kēia kanaka a hiki ke loli ma muli o ka makahiki a i ʻole overexposure i nā kani leo nui. Ma luna o ka pae lohe e lohe ʻia ai nā ultrasounds (nā alapine ma luna o 20 kHz) a ma lalo, nā mea hana (nā alapine ma lalo o 20 Hz).
- E nānā hoʻi: Nā leo kūlohelohe a me nā kani
Nā ʻano kani
- Kiʻekiʻe.Hoʻoholo ʻia e ke alapine o ka haʻalulu o nā nalu, ʻo ia, ka helu o nā manawa e hana hou ʻia ai kahi haʻalulu i kahi manawa i hāʻawi ʻia. Wahi a kēia ʻano, hiki ke hoʻokaʻawale ʻia nā leo ma ke ʻano he bass, no ka laʻana:ke kaomi ʻana me ka manamana lima i nā kaula o he bass pāpālua a me ka treble, no ka laʻana:he ʻawā. Ana ʻia ke alapine o nā kani i ka hertz (Hz) ʻo ia ka helu o nā haʻalulu i kēlā me kēia kekona. ʻAʻole e huikau me ka leo.
- Ka nui a i ʻole ka leo.Kaukaʻi ʻia i ko lākou ikaika, hiki i nā kani ke nui a nāwaliwali paha. Hiki ke ana i ka ikaika o ke kani e like me ka hana o ka amplitude nalu (mamao ma waena o ka palena nui o ka nalu a me ke kiko kaulike); ʻo ka pālahalaha o ka nalu, ʻoi aku ka nui o ke kani (kani nui) a ʻo ka nalu liʻiliʻi, ʻo ka haʻahaʻa ka ikaika o ke kani (leo nāwaliwali).
- DurationʻO ia ka manawa o ka manawa e mālama mau ai nā haʻalulu o kahi kani.Pili kēia i ka hoʻomau o ka nalu kani. Kaukaʻi ʻia i ko lākou lōʻihi, hiki ke lōʻihi nā kani, no ka laʻana:kani o ka huinakolu (mea kani) a pōkole paha, no ka laʻana:ke hoʻokuʻi puka.
- Pele puka. ʻO ia ke ʻano e ʻae ai i kekahi e hoʻokaʻawale i kahi leo mai kahi leo ʻē aʻe, no ka mea hāʻawi ia i ka ʻike e pili ana i ke kumu e hoʻopuka ai i ke kani. ʻAe ka timbre i ʻelua mau leo o ke kiʻekiʻe kaulike e hoʻokaʻawale ʻia, no ka mea me nā alapine ke hele pū me nā mele ʻoniʻoni (nā leo nona nā alapine he mau helu lehulehu o ka nota kumu). ʻO ka nui a me ka ikaika o nā harmonics e hoʻoholo i ka timbre. Hāʻawi ka amplitude a me kahi o nā harmonics mua i kahi timbre i kēlā me kēia mea kani, e ʻae ai iā lākou e ʻokoʻa.
