I ka lewa lewa a me ka leo pollution, ambient noise level (i kapa ʻia kekahi manawa walaʻau kāʻei kua pae, pae kani kuhikuhi, a i ʻole ka leo leo o ka lumi) ʻo ia ke kiʻekiʻe o ke kaomi kani hope ma kahi i hāʻawi ʻia, i kuhikuhi ʻia ma ke ʻano he pae kuhikuhi no ke aʻo ʻana i kahi kumu kani intrusive hou.
Ana pinepine ʻia nā pae leo ambient no ka palapala ʻana i nā kūlana kani ma luna o ke aupuni spatial e hoʻomaopopo i ko lākou ʻokoʻa me ka wahi.
I kēia hihia, ʻo ka huahana o ka hoʻokolokolo ʻana he palapala ʻāina contour pae kani. Hiki ke ana ʻia nā pae walaʻau ʻē aʻe no ka hāʻawi ʻana i kahi kikoʻī no ka nānā ʻana i kahi leo intrusive i kahi kaiapuni.
No ka laʻana, i kekahi manawa e aʻo ʻia ka walaʻau mokulele ma ke ana ʻana i ke kani ambient me ka ʻole o ka lele ʻana, a laila e aʻo i ka hoʻohui ʻana o ka walaʻau ma ke ana a i ʻole ka hoʻohālikelike kamepiula o nā hanana overflight.
A i ʻole, ua ana ʻia ka leo o ke alanui ma ke ʻano he leo ambient, ma mua o ka hoʻokomo ʻana i kahi pale leo hypothetical i manaʻo ʻia e hoʻemi i kēlā pae leo ambient. Ana ʻia ka pae leo ambient me ka mika pae kani.
Hoʻohana pinepine ʻia ia ma ka dB ma luna o kahi pae kaomi kuhikuhi o 0.00002 Pa, ʻo ia hoʻi, 20 μPa (micropascals) ma nā ʻāpana SI. ʻO ka pascal he newton no ka mika square.
ʻO ka ʻōnaehana kenimika-gram-kekona o nā ʻāpana, ʻo ka pae kuhikuhi no ke ana ʻana i ka pae leo ambient he 0.0002 dyn/cm2.
Ana 'ia ka nui o ka wala'au me ka ho'ohana 'ana i ka kānana kaumaha pinepine, 'o ka mea ma'amau ka unahi-kaumaha, no laila, 'ike 'ia nā ana i ka dB(A), a i 'ole decibels ma ka unahi-kaumaha A.
ʻO wau ʻo Joost Nusselder, ka mea nāna i hoʻokumu iā Neaera a me kahi mea kūʻai aku ʻike, makuakāne, a makemake hoʻi e hoʻāʻo i nā mea hana hou me ka guitar ma ka puʻuwai o koʻu makemake, a me kaʻu hui, ua hana wau i nā ʻatikala blog hohonu mai 2020 e kōkua i ka poʻe heluhelu kūpaʻa me nā ʻōlelo aʻoaʻo hoʻopaʻa leo a me nā kīkā.
