Kumhanya inzwi. Sound migumisiro zvakasikwa rwokugadzira

Kuongorora nyika isu akapoteredza aiva kukwanisa kunzwa munhu sechipo kubva hunhu. Nokuda kwaizvozvo tine mukana kunakidzwa trill shiri uye zvidimbu mumhanzi, wana-zviratidzo zvokunyevera nezvengozi uye kutaura nemumwe.

Kufunga hunhu inzwi, wefizikisi akapa mhinduro kuti tiri kubata zvemaziso nemafungu. Nokuti kuparadzirwa, unofanira kuva kwakavharwa nenyama svikiro. Mhinduro kumubvunzo chii kumhanya inzwi iri Vacuum pasi akanaka ezvinhu (kwakakwana kushayikwa fuma) zvinoratidza pacharo. Muna Vacuum Haagoni kuparadzira. Sound velocity azvaitwa kuenzana razero. Asi izvi hazvirevi kuti hapana nzvimbo iri enyambo acoustic mananara. Vamwe vano- explainable hunhu uye zvakananga akarondedzera kukura yakazaruka dzezvimwe vanhu nzvimbo. Akadzvova michini zviri motokari, kurira vibrations ari university. Mumwe mananara vane asi kuwana kutsanangura Somuenzaniso, dzakadai ruzha pematanho yepasi pose sokupenya, kana kuderedzwa maitikiro "zvisaririra" yacho chitundumusere-musere.

In ezvinhu akasiyana-siyana ari velocity nokurira ane imwe zvikuru empirically. kupararira Its pakarwiwa kuvapo nezvipingamupinyi. Sezvo tiri pakubata zvemaziso nemafungu, tinogona kuona kuti kurira anoenda kumativi zvipingamupinyi izvi. Izvi Fani kuzorwa mafungu inonzi diffraction. Low mafungu zvakawanda amenable pazviri pane mukuru. Khor vanoshandura pakona, kutanga "anorasikirwa" dzakakwirira manzwi, uye ipapo anova inaudible pasi vaimbi izwi.

The mugumisiro ruzha utano hwevanhu vaifunga refu asati Panovhurwa infrasound. The jenareta inaudible kurira frequencies kunogona kukanganisa kufara guru kuwanda vanhu. Saka wefizikisi of America Robert Wood rwunoverengerwa ane panzvimbo kujairika chiedzwa. Akatakura yemitambo infrasound jenareta, tendeukai pamusoro uye akapupura sei zvose vaoni vakambundirana kujairika wokusagadzikana uye kufunganya.

Kunyange zvakadaro kutanga sezvo kwaita "kubhururuka Dutchmen" - zvikepe pamwe akafa chikwata, vachiedza kutsanangura kukanganiswa infrasonic frequencies wakadenha gungwa rakadzikadzika munguva dutu.

Akapiwa hunhu kupararira pakati ruzha, zvinganzi vakagumisa kuti kumhanya inzwi munharaunda dzakasiyana ane yakasiyana zvikuru. Zvave zvichinzi kuti kurira propagates mune magasi panguva aimhanya siyana. In ichi rinobata zvinoriumba hazvirevi kufurira kuti arambe achirema negasi, izvozvo zvinoenderana samolecular uremu.

In mvura, mutsindo aienda kunyange nokukurumidza. Heano chete munhu nzeve zvakaipa chinosiyanisa nayo mumamiriro ezvinhu akadaro. Sound mafungu pakuwanza mumvura, akaratidza kubva eardrum rinenge zvachose. Asi Leonardo da Vinci awana chinhu nzira yepakutanga kuteerera pasi pemvura mitinhimira. Kuti izvi zvidaro, akaronga kushandiswa akatura mumvura chovha. Kana tikaenzanisa kumhanya inzwi mumhepo (331 m / s) uye mvura (1435 m / s), zvinoita chamber mashoko akasiyana zvinobatsira denser unosvikirwa kuti aparadzirwe.

Nezvishoma vakarova zvinyorwa zvose. Kumhanya inzwi mavari anogona kusvika 5000 m / s. An dzinonakidza ruzivo zvinogona kuitwa nevakawanda njanji zvakapoteredza nzeve. Kana munhu ari nechokure rakarova nazvo nenyundo, tinogona kunzwa zvakajeka kwakafanorongwa maviri. First - ndiwo mashoko ruzha yaunganidzwa pakuparadzira simbi, uye wechipiri - sefungu akasvika nendege.

Nokuti vazhinji muviri mananara kurira velocity rudzi mureza, pokutangira kuenzanisa. varwi Modern sechinhu chikuru budiriro wake supersonic nezvaanogona. Kuyera ndima imwe chikamu inzwi wave, zvinokwanisika kuziva daro dzakakwirira zvakarurama.

Kushandisa ruzha migumisiro munyaya dzakasiyana-siyana zvinoitwa nevanhu Zvinoshamisa ayo kusiyana.
