Sound kuekueni. E pili ana. Hopena ma luna o kanaka

E noho nei i loko o ke ao nei o kekahi nalu, kekahi mau Kahalaopuna i ka hopena o ke kani. Sound kuekueni - mea,ʻaʻole pono ke kŰia hoʻouna pūʻia maila kela wahi keia wahi, akā, i ke kumu o ka makemake, akā, i 'ike i nā mea hana o ka ikaika. Hoʻokō i kekahiʻano o nā hana, ke kani mea hiki ke ao aku ia oukou e pili ana i ka pilikia, makemake, lilo i kekahi mea o ka 'ōlelo. Mākou e olioli ole, e hoolohe i na manu e mele ana, palupalu mele, komo i loko o ke kamailio ana me nā kanaka.

Sound kuekueni i nui ole wale no kānaka akā, no hoi no na holoholona i hoʻohana kani e ola.

Ma kona ano, i ke kani o ka ma paʻi laholio nalu, i ka poe hiki ke hoʻopulapula ma ka puaʻa hiwa, ke kinowai, kinoea i loko. Sound kumu Sound kuekueni i kamakawiwo ole (ÿano oscillations), i mea pinepineʻike makaʻole maka. Ma ke kani kumu i loaʻa physical kino ka hana ana kuekueni no kekona (manuʻu ole kamakawiwo ole) me ke alapine (frequency) o hookahi 16-20000. Sound kuekueni hiki i paa kino (kui pńpa), gaseous (ea mokulele hēkī), wai (kai ale).

Mawaena o ke kani ano e hoomaopopo mau mea kiko'î: i ka leo - alapine kani kuekueni; ka leo - he sonic nalu ikaika hawewe. Ke pa alima o ka leo ua manaoia e e 1 Bel (ka mea i kapaʻia ma hope o kekahi o ka inventor o ke kelepona - Aleksandra Grehema Bell). ʻaneʻane kekahi Bela ua ole ia, ia mea oi kupono e hoʻohana decibels, e like me kekahi-umi o Bel. I mea e loaa i ka maopopo manaʻo o ka Ana o ka buke i ka e ia i loko o no ia o ka 10 DB - hńwanawana ia; 20-30 DB hoʻopili like me ka mau leo i loko o ka lumi ola; 50 DB - keia mea i ka awelike hea ka leo; he walaau ka mana i loko o 80 DB kona kalaka engine mea e holo mai ana; physiological eha paepae i loko o kānaka ia lŘlŘ i 130 DB; 180 DB ke alakai i ka rupture o ka eardrum.

Noonoo pono i ka hawewe kani ana o kekahi nä alapine, he kiʻekiʻe-alapine (frequency) hawewe loaʻa i ka himeni o ka manu, a hiki i ka mea haʻahaʻa leo loaʻa i ka leo o ke kalaka engine. A me ka laulā a pau o ka waiwai a me ka ano e OAOOUIEeE ale o kekahi ano, e hoʻomano hoʻohana na nä hawewe kani i loko o nā kula. loli waiwai he kani ua 'Imi hoʻohana' ia i loko o kaʻimi loa i ka lewa o ka moana kai hohonu. A pau i ka ikea Keia, no kekahi laʻana, ua hoʻohana 'ia e hooholo mamao ma ka echolocation. A luku laʻana hiki e hoike ia maoli sonar'ōpeʻapeʻa.

A kūikawāʻano o ultrasound acoustic kuekueni ka loa ka hoʻokō 'ana i loko o ka lima o ka lapaau a me nā noiʻi. Mau kuekueni nāʻale me nä alapine o ka 20 000 Hz. Kēia oscillation aaeei i ka helu o ka hanana waiwai. Maalo ae la oia ma ka wai, i ka ultrasound o kona baila aʻela i (cavitation) me ka hanana o ka wai ka mea pahana. E ho ohana i ultrasound oihana mua e hoʻokaʻawale, mai ka ili o ka metala hahi i ka puaʻa hiwa. Ultrasound apono 'hui pu iaʻi o fluids i mea immiscible ma lalo ano o keia, no ka laʻana, emulsions me ka aila kumu. Ultrasound apono 'i ka saponification o kona kaikea a. Keia rula waiho i ka mea holoi machines. Waiwai o ka ultrasound e paka palaoa keia i ua hoʻohana ma o ka ultrasonic nä soldering hao.

ua A kūikawā ano o ke kuekueni i ka 16 Hz kapaia infrasound. Ua ua ike i na kuekueni o keia alapine (frequency) hiki e ola ia ma luna o ka kanaka kino. Ma nä alapine o 4-8 Hz ua ikeia kamakawiwo ole o na nā loko, i ke alapine (frequency) ma 12 Hz triggers ka seasickness.

Nā kumu i e infrasound hana me ka nui surfaces, a e ke ÿano kuekueni o ka hana ' (me mechanical me Kinohi) a me ke kinowai a me nā kinoea kahe ana me ka māpuna waiwai (hydrodynamic ole aerodynamic me Kinohi).
