Vibrations Sound. codsiga la taaban karo. Saameynta aadanaha

Dunida ku nool ee hirarka kala duwan, mid joogto ah ayaa dareensan in saamaynta dhawaaqa. vibrations Sound - ma ahan oo kaliya arrin isaga meel walba la socda, laakiin sidoo kale laga helaa raaxo, laakiin sidoo kale qalab macluumaad awood badan. Bandhigyada kala duwan ee hawlaha, dhawaaqa awoodo si uu ugu digo halista, raalli ahaanshihiisa, noqon loola isgaarsiinta. Waxaan ku faraxsanahay in ay dhegeystaan Shimbiraha music jilicsan heeso,, galaan wada hadalka dadka kale.

vibrations Sound waa muhiim ma aha oo kaliya loogu talo galay dadka, laakiin sidoo kale xayawaanka in ay isticmaalaan dhawaaqa si ay u noolaadaan.

By ay dabiicadda, dhawaaqa waa hirarka laastikada farsamo, taas oo ay awoodaan in ay dacaayad in adkaha, dareeraha, gaasas in. Ilo Sound vibrations Sound keeni gariirka (oscillations farsamo), taas oo inta badan waa isha la arki karin. By dhawaaqa ilo ka mid noqon kara jirkooda jirka jimicsi vibrations per labaad (gariiraan ama gariirka) la soo noqnoqoshada ah mar 16-20000. vibrations Sound keeni karaan meydadka adag (qolof ah string), gaseous (jet hawada), dareere (hirarka badda).

Ka mid ah sifooyinka dhawaaqa in la kala saaro laba xuduudaheedu: codka - gariirka codka inta jeer; mugga - Ilodanimada inayan la ruxruxo Sonic. unit ee mugga waxaa loo arkaa inay 1 Beel (waxaa loo magacaabay ka dib markii mid ka mid ah hindisa ee telefoonka - Aleksandra Grehema Bell). Ku dhawaad hal Beel looma isticmaalo, waxay u badan habboon in la isticmaalo desibelo, loo siman yahay si hal-tobnaad Beel. Si in ay fikrad cad ah oo aragti ah ee mugga in la tixgeliyo in 10 dB galay - waa faqaan, 20-30 dB dhigmaan qaylada caadiga ah ee qolka fadhiga, 50 dB - taasi waa mugga call celcelis ahaan, awood qaylada 80 dB engine xamuul ah oo waa soo ordaya; nafsaaniga ah marinka xanuun in aadanuhu waxay dhacdaa at 130 dB; 180 dB waxay keeni kartaa in dillaac ah ee durbaanka.

Ka fiirsaneysa mowjado dhawaaq of firikuwensiyada kala duwan, a hirarka ee hirka sare waxaa ka mid ah heesaha shimbiraha, u dhawaaq yar yahay waxaa ka mid ah dhawaaqa engine xamuul ah. Iyada oo kala duwan ee guryaha iyo sifooyinka kala duwan hirarka nooca kala duwan oo dhan, mowjado dhawaaq ah hubkaas ayaa loo isticmaalaa in dhinacyo kala duwan. guryaha dheecaan ahaayeen dhawaaqa si firfircoon loo isticmaalaa in sahaminta badda qoto dheer. Oo dhan u eg loo yaqaan, tusaale ahaan, waxaa loo isticmaalaa si loo ogaado masaafo in echolocation. Tusaale A Garaaci laga yaabaa in lagu soo sheegnay Fiidmeerta SOONAARKA dabiiciga ah.

nooca A gaarka ah ee ultrasound vibrations loomana baahno waa hab aad wax ku ool gacmaha dhakhaatiirta iyo cilmi kale. vibrations Kuwanu waa hirarka la mawjadaha 20 000 Hz. mode oscillation waxa uu leeyahay tiro ka mid ah sifooyin u gaar ah. Gudbinta biyaha iyada oo loo marayo, ultrasound waa ay daartu (cavitation) la dhacdo of dubbe biyaha. Isticmaalka xubno ultrasound fullaacin karaa dusha sare ee biraha burburin cunnooyinka adkaha ah. Ultrasound ogolaanaya qodan oo cabitaan ah kuwaas oo immiscible ku hoos jira xaalad caadi ah, tusaale ahaan, emulsions leh sal saliid. Ultrasound ogolaanaya saponification ee dufanka. Mabda 'Tani been at the Makiinadaha dhar dhaqidda qalabka. Hantida of ultrasound in ay soo saaraan saamayn burburiyo ayaa loo isticmaali jiray in birta, kabida ultrasonic.

nooca A gaarka ah ee vibrations ilaa 16 Hz waxaa lagu magacaabaa infrasound. Waxaa la og yahay in gariirka ee inta jeer tani waxay noqon kartaa saameyn daran on jidhka bini'aadamka. At mawjadaha of 4-8 Hz waxaa dareemay gariirka ee xubnaha gudaha, soo noqnoqoshada at 12 Hz dood ah seasickness.

Wararka ayaa waxaa laga yaabaa in mashiinada infrasound la dusha weyn, taas oo ka dhigi vibrations farsamo ee soo noqnoqoshada hooseeyo (asal si farsamaysan) ama cabitaanno iyo gaasaska la barwaaqaysan yahay guryaha qasan (hydrodynamic ama asal aerodynamic).
