Sound vibrations. Kushanda. Impact pamusoro munhu

Kurarama munyika ine mafungu siyana, imwe nguva anonzwa matambudziko inzwi. Sound vibrations - haisi kutanga vaimuperekedza kwese, asi vangakupawo mafaro, asiwo simba mashoko chokushandisa. Kuita zvakasiyana-siyana mashandiro, kurira anokwanisa kunyevera nezvengozi, mafaro, ave nzira yokukurukurirana. Tinofara kuteerera shiri kuimba, nyoro music, kupinda kukurukura nevamwe vanhu.

Sound vibrations zvinokosha kwete chete vanhu asiwo mhuka kushandisa inzwi yokupukunyuka.

By pezvawakaita, kurira chinhu zvemaziso kwakavharwa nenyama mafungu, anogona kuparadzira mune zvinhu zvakaoma, mvura, magasi ari. Sound mabhuku Sound vibrations vanokonzera vibration (zvemaziso oscillations), izvo kazhinji ziso asingaoneki. By ruzha zvinyorwa dzingasanganisira miviri yenyama achiunza vibrations por yechipiri (achidedera kana vibration) pamwe kakawanda kamwe 16-20000. Sound vibrations kungaita miviri yakasimba (tambo goko), gaseous (mhepo ndege), mvura (gungwa mafungu).

Pakati ruzha unhu kusiyanisa parameters maviri: izwi - Frequency ruzha vibrations; vhoriyamu - a sonic chinozunguzirwa amplitude. The chairema inzwi kuonekwa 1 Bel (zvakanzi zita rimwe vakatanga foni - Aleksandra Grehema Bell). Chinenge chikamu chimwe Bel haasi kushandiswa, zviri nyore kushandisa decibels, zvakaenzana chimwe-chegumi Bel. Kuti tinzwisise yakajeka divi iri vhoriyamu kufungwa kuti 10 db - uchingotizevezera nayo; 20-30 db dzinoenderana zvatinosiita ruzha muimba yokutandarira; 50 db - ichi ndicho avhareji kufona vhoriyamu; mheremhere simba muna 80 db rori injini iri achimhanya; vasiri kurwadziwa pachikumbaridzo muvanhu ndepana 130 db; 180 db kungaita kuti atsamwira yacho eardrum.

Kufunga ruzha mafungu frequencies siyana, mukuru-kakawanda mafungu dzinosanganisira kweshiri, kuti shoma ruzha zvinosanganisira kurira rori injini. With zvose kuwanda zvivako uye unhu zvakasiyana mafungu zvakasiyana hunhu, mutsindo mafungu zvinonzi nevakawanda kushandiswa muminda siyana. Urume ehupfumi vaiva ruzha ari kushingaira wakashandiswa ubanguranyika rakadzika gungwa. Vose anozivikanwa Zvisaririra Somuenzaniso, inoshandiswa kuona marefu ari echolocation. A achirova muenzaniso anogona kutaurwa dzinongoitika Akash zviremwaremwa.

A rinokosha mhando Ultrasound acoustic vibrations unoshanda chaizvo nzira mumaoko vanachiremba uye dzimwe nevaongorori. vibrations ava mafungu vane frequencies 20 000 Hz. Izvi oscillation muoti ane vanoverengeka nemamwe zvivako. Achipfuura mvura, kuti Ultrasound raro Kubika (cavitation) pamwe panowanikwa mvura sando. Kushandisa Ultrasound zvinhu zvinogona patsanura kubva pemvura simbi achapwanya nezvishoma. Ultrassom anobvumira vaiitawo basa zvinwiwa izvo immiscible pasi vanhuwo ezvinhu Somuenzaniso, emulsions namafuta chawo. Ultrassom anobvumira saponification kwemafuta. Pfungwa iyi riri panguva mudziyo washing machine. Pfuma Ultrasound kubereka unorema kushanda rave kushandiswa ultrasonic pokunamatidza simbi.

A mhando chaiye vibrations anosvika 16 Hz inonzi infrasound. Zvinozivikanwa kuti vibrations ose kakawanda ichi inogona kurwadza zvainoita muviri womunhu. At frequencies pamusoro 4-8 Hz Runonzwika vibration pamusoro nhengo dzomukati, kakawanda pa 12 Hz kunokonzera ane seasickness.

Zvinotisimbisa zvingava infrasound michina ine hukawanika huru, iyo kuti zvemaziso vibrations yakaderera maitikiro (zvokuimba mavambo) kana mvura uye magasi inoyerera hwekutambudzika ehupfumi (hydrodynamic kana aerodynamic mavambo).
