Amaza omsindo: umqondo kanye nezici

Izwe elisizungezile, singasho kugcwale ushayele ezweni umsindo, ngoba zonke elisizungezile njalo amazwi, umculo, zitshiyoze izinyoni, umsindo emoyeni. amaza omsindo ukusiza abantu ukuxhumana, uthole ulwazi mayelana nezwe elibazungezile. Animal imisindo ebaluleke ngokulinganayo. Ngokombono physics, imisindo kunyakaza mechanical lokusakaza ku-medium nokunwebeka: amanzi, ummoya, okuqinile nokunye. izindlebe Human uzwe umsindo, lapho imisindo uhla kusuka 16 kuya 20,000 Hz. Oscillations nge ephakeme noma amaza ephansi akuzona ezwakalayo ukuze abantu.

Isayensi udluliseleke uyixazululile ezihlukahlukene nezindaba, kuhlanganise nezindaba ezihlobene izici izakhiwo wokuqulwa kwecala. Isihloko ekutadisheni udluliseleke bokuphila ngokuqondile uhlaka ukuzwa, isakhiwo yayo, futhi isenzo zedivayisi. umsindo Architectural iye, ngokufunda indlela yokusebenzisa amaza omsindo egumbini, ucabangela ithonya ukuma nosayizi egumbini umsindo, ukutadisha izakhiwo izinto nge ekwandeni wamanje kanye nokucindezela imisindo. Musical udluliseleke sikhuluma ngokuhoxiswa cwaningo zezinsimbi zomculo, ihlola isimo umsindo best of a insimbi ethile.

Physical Acoustics study ngokwabo amaza omsindo, umsindo amagagasi, muva nje buye abe ikhava iyehla iyenyuka ukuthi zingaphezu amakhono ohlelweni womuntu sokuzwa.

Uhlelo oluyisisekelo oluthi imiqondo of umsindo

Ukufika kombuso umsindo kubangelwa kunyakaza mechanical emizimbeni nokunwebeka kanye nesimo. Air ngomsindo umqhubi. Lokhu kufakazelwa isipiliyoni Roberta Boylya. Uma ufake umzimba umsindo noma ngaphansi isikhencezo isifutho emoyeni ke okungenani uzotshala aphume emoyeni insimbi umsindo iyoba buthaka. Lapho umoya ngaphansi ukuphela insimbi, umsindo liyophela.

Phakathi oscillation umzimba yanjalo kudala ingcindezi ongathandeki ungqimba emoyeni ezakhelene ubuso bayo, abese licindezele lesi sendlalelo. Ngenxa yalokho, wokusakazeka amagagasi esikhaleni emoyeni iqala nge oscillation ungqimba emoyeni eduze kwamanzi emzimbeni.

Ngokushesha nje lapho amaza omsindo asakaze ngokusebenzisa isikhala, Damping umsindo siyenzeka, okuyinto lihlotshaniswa izinqubo ezithile engelapheki. Umqondo wukuthi ingxenye amandla eyalo igagasi umsindo amuncwa ophansi.

Coefficient ukumuncwa ukubaluleka okuyinto ilingana isilinganiso umsindo omuncwa medium amandla langena imvelo. Ngesikhathi Coefficient ukumuncwa kuthinta kombango noma viscosity medium, conductivity yayo ezishisayo kanye kwabantu medium ijubane wave esiphelweni.

Ukusabalalisa wave naphakathi wake kuziwa ilinganiselwe. Ngemva kwalokhu umngcele iqala kwamanye naphakathi okuyinto yakhiwa nezinye izinhlayiya kanye lapho nezinye Isivinini umsindo. Kuleli umngcele eyenziwe kuveza umsindo. Uma le izinhlayiya underpressure liphenduka ukufingqa, kanye ukufingqa - e cleaner.

Lo mphumela kwenzeka ngoba kunyakaza ukuthi asikaze kuletha safinyelela emngceleni wakwa-medium, komunye izinhlayiya naphakathi futhi babe umthombo igagasi elisha. wave Secondary uyokwendlala hhayi kuphela e medium yesibili, kodwa futhi omunye kuyo ekuqaleni wafika. Lokhu kuyoba ibonisa amaza omsindo.

Ngesikhathi esibonakalayo kuyinto ndima olungaphelele umsindo ku-medium wesibili kanye ukumuncwa olungaphelele umsindo. Ingxenye amandla kubonakala kuzoncika isilinganiso density aphakathi nendawo, kanye isimo esibonakalayo. Ngokwesibonelo, kubonakala igagasi umsindo lokusakaza emoyeni, isuka endaweni emananzi noma okuqinile cishe ngokuphelele. amaza omsindo asakaze endaweni okuqinile, cishe ngokuphelele ziboniswe ekusebenzisaneni ne air.

Ngemva kokucabanga mkhuba ngqo okuhlobene okuvela echo. Ingqikithi zalesi simo itholakala lokuthi ukuthi umsindo uvela emthonjeni kuya izithiyo ezithile, okuzoba imingcele aphakathi, kubonakala kuwo, ukubuyela endaweni nesenzakalo of igagasi.
