Ruzha kudzidza. Midziyo nokuti ruzha chipimo

Ruzha yakatipoteredza - bedzi zvisingawanzoitiki zviitiko, murume ano chinogona kunyudza pachako ari runyararo. Panyaya iyi, murau mutengo anowedzera ruzha parameters. Kumabasa, somuenzaniso, inokosha zvinodiwa pamusoro sangano kwekushanda ezvinhu. Zvinhu zvinodiwa vakadaro vachauya uye optimum inzwi nemigumisiro. Zvisinei, ruzha kudzidza kungadiwa mune mamwe mamiriro ezvinhu - mune zvokurapa Zvivako, paruzhinji uye, chokwadi, kumba. Nokuti chinangwa ichi, chinokosha mano - inzwi chechetere mamita. Asi kutanga ndiko kunzwisisa hunhu inzwi pacharo.

ruzha zvinyorwa

Vazhinji muguta ruzha kunotangira anthropogenic manyuko inzwi emagetsi. Somuenzaniso, gwenya chokufambisa, mhepo kuti ipfuure pakati zvivakwa, engineering zvekushandisa hurongwa, uye zvichingodaro. D. Kazhinji, zvikonzero zviri ruzha mhando iyi kunaka, nekuti ivo hunodzorwa yakaderera frequencies, uyewo runobva kuchinja dzokuAustralia mhiri siyana. Izvi zvinogona kuonekwa kunyanya basa maindasitiri emakambani, uye kukurukurirana midziyo.

Zvechokwadi, kupfuura zvakanaka, maererano acoustics, zvinhu segwapa kunze kweguta. Panyaya iyi, panobva anoita se chisikigo pachacho. Chimwe chezvinhu zvinofadza uye vakazorora ruzha pagungwa, kunoratidzwa idzokororo uye kwazvo vibrations. The anononoka uye monotonous kurira anosika dzakasiyana uye inokwezva zvomumvura mutinhimira kuti chinosimbisa tsinga.

chiridzwa mudziyo

Sound pamwero mamita kutengeswa nhasi nhasi yakakurumbira digitaalinen namano. Vane diki uye akasimba purasitiki kwedzimba, izvo nechimwe maikorofoni - zvisinei, maatomu akafanana izvi zvinogona revatema kupinda mudziyo. Chishandiso Izvi zvinosanganisira kuva gudzazwi, Sefa okunze, chiedza detector. Kutaura zvazviri, vanhu nzeve ane zvakawanda zvakafanana zvikamu functionality. Uyewo, munhu anokosha nzira inoita pakudzidza ruzha chete kugadzira parameters akawanda panguva imwe chete. Filters akakunda manzwi frequencies siyana, uye ruzivo pamusoro reflectivity kuyerwa anoteererwa pamusoro sefa mu decibels. Panyaya muviri, vakawanda inzwi pamwero metres ushande bhatiri simba, nokuchengeta zvinogona dzinosiyana 50 kusvika 70 maawa.

musimboti oparesheni

Pamusoro uchishandisa musimboti, muchiitiko ichi, zvikuru zvakakodzera kuenzanisa mudziyo aine microphone. Musiyano mukuru uchava kuti kurira pamwero mita ikasakendenga munguva kuyerwa ane voltmeter, munhu calibrated Decibel. Sezvo yemagetsi chiratidzo rukova goho kubva maikorofoni yakaenzana yepakutanga ruzha pachiyero chirungiso iri acoustic kumanikidzwa, izvo anoita pamusoro diaphragm achaita yakafanana voltage kuwedzera pane kubvuma ari voltmeter. On musimboti ichi uye vakavaka ruzha kuyerwa, izvo parameters zvinoratidzwa ari kuratidzwa. Kuti aite mabasa kuyerwa nokurira kumanikidzwa chiratidzo iri vakayambuka chinokosha filters - izvi zvinoitwa panguva ari munzira kubva maikorofoni kuti voltmeter.

Sezvo nzeve anogona kunzwisisa ruzha kunotsamira kwete kakawanda ruzha ehupfumi, asiwo nokuda kwayo kukura, mune mano zvinopa marudzi vanoverengeka mupise zvinhu. The chaiyo mudziyo kunobva chii vari zvinoitwa kushanda chikamu ruzha pamusoro kuyerwa. Filters kuti zvibvire kuti vatevedzere mashoko amplitude-kakawanda chakarondedzera pamamiriro ruzha simba.
