Sound mafungu: pfungwa uye zvinhu

Nyika dzinoitwa isu, tinogona kudana nechivimbo nyika inzwi, nekuti zvose kumativi wedu nguva manzwi, mumhanzi, kuti kurira kweshiri, inzwi mhepo. Sound waves kubatsira vanhu kukurukura, kuwana ruzivo pamusoro nyika yakavapoteredza. Ruzha Animal vari zvakaenzana kukosha. Mukuona wefizikisi, ruzha vari zvemaziso vibrations pakuwanza iri kwakavharwa nenyama svikiro: mvura, mhepo, yakasimba uye nezvimwewo. nzeve Human vanogona kunzwa inzwi, kana kurira frequencies vari zvinobva 16 20,000 Hz. Oscillations vane yakakwirira kana dzakaderera frequencies havasi anzwike vanhu.

Science acoustics kwave kutaurwa akasiyana-siyana panyaya, kusanganisira nyaya chokuita zvainyanya uye zvivako zviri kunzwa. Nyaya pakudzidza vasiri acoustics iri zvakananga kuti nhengo kunzwa, ayo mamiriro, uye Zvakaitwa mudziyo. Architectural acoustics yave nokudzidza kushandisa ruzha mukamuri, tichifunga zvinoitwa pezvakaita uye kukura mukamuri kurira, kudzidza ehupfumi nezvinhu pamwe magetsi kuwanda uye kudzvinyirira mazwi. Musical acoustics inotaura kudzidza zvemimhanzi, rinoongorora mamiriro ezvinhu akanakisisa ruzha imwe chiridzwa.

Physical Acoustics zveBhaibheri pachavo ruzha, ruzha mafungu, ichangobva kupfuura yava uyewo kuva kavha nokufamba vari mhiri nezvaanogona ose auditory dzevanhu hurongwa.

The inokosha Dzidziso acoustics

VeMubatanidzwa inzwi kukonzerwa zvemaziso vibrations ose kwakavharwa nenyama yenyama uye runyararo. Air nokuda inzwi chevaimbi. Izvi zvakaratidza nezvakaitika Roberta Boylya. Kana waisa inzwi muviri kana pasi bhero ane mhepo pombi, ipapo zvichida kupomba kubva mhepo bhero ruzha ichava simba. Kana mhepo pasi bhero magumo, kurira achamira zvachose.

Panguva oscillation muviri rave pave kunaka kumanikidzwa mudenga rukoko yakabatana ayo pamusoro, ipapo anorumanya rukoko urwu. Somugumisiro, Mashoko mafungu dzedenga nzvimbo kunotanga oscillation dzedenga rukoko pedyo muviri pamusoro.

Pangosvika inzwi mafungu kuparadzira kuburikidza muchadenga, mutsindo damping ari kuchengetwa, iyo chokuita nedzimwe pezvakaitwa kusingarapiki. Pfungwa iri riri kuti chikamu simba kutakurwa chakanaka chinozunguzirwa yokuita zvinoitwa svikiro.

The Absorção de Água coefficient zvakakoshera iyo akaenzana nhamba inzwi simba yokuita zvinoitwa svikiro kuti simba kuti wakapinda zvakatipoteredza. Panguva Absorção de Água coefficient rinokanganisa kukweshera kana viscosity kuti svikiro, ayo chafariz conductivity uye arambe achirema pamusoro svikiro chinozunguzirwa kupararira nokukurumidza.

Kuparadzira ari svikiro chinozunguzirwa nokusingaperi anouya pakunogumira. Pashure muganhu uyu anotanga mamwe svikiro iyo rinoumbwa zvimwe zvacho uye umo imwe inzwi velocity. On muganhu yakagadzirwa inzwi Kufungisisa. Kana ichi underpressure inoramba ichichinja condensation, uye condensation - mu Vacuum.

Izvi kunoitika nokuti vibrations kuti kuchizunguzira Zvinounza kumuganhu svikiro, kune rimwe Svikiro nezvimedu uye kuva kunobva itsva wave. Secondary chinozunguzirwa achatambanudza kwete svikiro wechipiri, asiwo mumwe iyo pakutanga akauya. Izvi zvichava kuratidzwa kwokubwinya ruzha.

At inowanikwa iri zvishomanana ndima inzwi munzvimbo yechipiri svikiro uye zvishomanana Absorção de Água nokurira. Huwandu simba akaratidza achavaponesa nhamba svikiro arambe achirema, uyewo mamiriro inowanikwa. Somuenzaniso, akaratidza mutsindo chinozunguzirwa pakuwanza mudenga, kubva mvura kana paasingazonyuri rinenge chose. Sound mafungu hunopararira pakati yakasimba, anenge chose kuratidzei panguva inowanikwa pamwe mhepo.

On kufungisisa chinoshamisa akarondedzera panowanikwa ungira zvakananga. Musimboti Fani iyi iri yokuti kurira kunobva kupi kune imwe zvipingamupinyi, ichazovapo miganhu svikiro, uye zvinoratidzwa pauri, kudzoka kunzvimbo panowanikwa wave.
