Ngesantya yesandi. ngendima yesandi nendalo nezobugcisa

Ukuvavanya ihlabathi esiphila ukukwazi ukuva umntu njengesipho esivela indalo. Ngenxa kule sifumana ithuba lokuphila Trill iintaka kunye amaqhosha zomculo, ukufumana-elumkisa amaza malunga nobungozi kunye nokunxibelelana nabanye.

Ukuqwalasela uhlobo isandi, physics wanika impendulo ukuba sisebenza kunye mechanical ngamaza. Kuba ukwabiwa, kufuneka ube ilastiki medium. Impendulo umbuzo wokuba yintoni isantya isandi kungekho phantsi kweemeko ezifanelekileyo (kukunqongophala okupheleleyo iziyobisi) icebisa ngokwayo. In zidle akakwazi ukusasaza. Velocity Sound ngokulandelana ilingana zero. Kodwa ke oku akuthethi ukuba akukho ndawo kwi nesenzeko kwinqakwana ive. Ezinye uhlobo kakhulu explainable kwaye ezinxulumene ngqo kuphuhliso namabala indawo yabantu. Ukubhonga injini izithuthi, isandi ukungcangcazela kwisiphekepheke. A izenzakalo ezithile kodwa ukufumana ingcaciso, umzekelo, ezifana izandi eziyelelene ukukhanya cosmic, okanye ezisezantsi-rhoqo "imizila" ye kwisiphekepheke.

Kwiimeko ezahlukeneyo uqina of esinengqondo ixabiso ethile empirically. ukusasazeka kwayo kwakugquba bubukho imiqobo. Njengoko ukuba sisebenzisana kwamaza mechanical, sinokubona indlela isandi kuhamba nale miqobo. Le nto nxamnye ngamaza ebizwa diffraction. Amaza Low iSADC okungakumbi phezulu. Khor, sijike lembombo, kuqala "ulahlekelwa" eziphakamileyo amazwi, waza ke uba inaudible iimvumi eliphantsi ngelizwi.

Isiphumo umsindo kwimpilo yabantu babecinga kudala ngaphambi kokuvulwa infrasound. Nale generator inaudible umsindo zingachaphazela indlela aziva zoqhaphelo olukhulu zabantu. Ngoko ke, nokwakheka Melika Wood wothulelw eksperimenti kunokuba engaqhelekanga. Wayephethe yeqonga infrasound wenkunkuma, vula ngalo abona ngayo bonke ababukeli bamkela Mzoli engaqhelekanga kwaye nexhala.

Enje into njengoko ukuvela "Dutchmen eziphaphazelayo" - iinqanawa kunye neqela kwabafileyo, ezama ukucacisa impembelelo ezitsho infrasonic eyenziweyo enzonzobileni yolwandle ngexesha uqhwithela.

Ngenxa yobume andise kwamaza isandi, kunokwenziwa isigqibo sokuba isantya isandi kwiindawo ezahlukahlukeneyo ubukhulu ezahlukeneyo. Kuye kwaphawulwa ukuba isandi Ukhuthaza bayo ngezantya ezahlukeneyo. Kulo esebenzayo candelo ayikho impembelelo lexinene igesi, oko kuxhomekeke ezinto ubunzima.

Xa ulwelo, isandi uhamba ngokukhawuleza. Nazi nje indlebe yabantu embi izahlule kwimeko enjalo. Amaza Sound zandise emanzini, kubonakala phantse ngokupheleleyo ukusuka indlebe. Kodwa ULeonardo da Vinci uye wafumana indlela original ukumamela izandi kwamanzi. Ukuza kuthi ga ngoku, wacebisa ukusetyenziswa bewuhlisele kungena nesimbo emanzini. Ukuba sithelekisa isantya isandi umoya (331 m / s) kunye namanzi (1435 m / s), kunokwenzeka ukuba ukulandelela inzuzo ecacileyo luthe eliphakathi ukuba asasazwe.

Okuqinileyo ukubetha zonke iingxelo. Isantya isandi kuzo uyakwazi ukufikelela 5000 m / s. Amava umdla kungenziwa kaloliwe eqhelekileyo lokunithumelela le indlebe. Ukuba umntu umgama hit ngehamile, sinako ngokucacileyo ukuva hits ezimbini. Okokuqala - oku ulwazi isandi ezifunyenwe ngokusasaza intsimbi, kwaye eyesibini - ngumtshangatshangiso ngenqwelo-moya.

Ngokuba inani elikhulu of ophathekayo Velocity isandi luhlobo umgangatho, kwindawo yokuqala ukuze uthelekiso. alwela Modern ithathwa njengokuba mpumelelo inkulu izakhono zakhe supersonic. Umlinganiselo enkalweni inxalenye ethile lencinibakazi ephilileyo, kunokwenzeka ukuba ukujonga umgama ngokuchanileyo eliphezulu.

Ukusebenzisa iziphumo zesandi kwiinkalo ezahlukeneyo zezinto ezenziwa luluntu ngobambana abafundi abangafaniyo yayo.
