Izixhobo zonyango lwe-acoustic zinokwahlulahlulwa ngokwezinto zokufunxa isandi, izixhobo zokusasaza kunye nezixhobo zokugquma isandi ngokwemisebenzi yazo.Phakathi kwazo, izinto ezifunxa isandi azikho nje ipleyiti yesiqhelo yokufunxa isandi, kodwa kunye nomgibe ophantsi oqhele ukusetyenziselwa ukufunxa amaza aphantsi.Okokuqala, kufuneka sazi ukuba isandi siya kuqhubeka njani sisasazeka emva kokuba sisasazeke kwiindonga zethu eziqhelekileyo.
Isandi esibonakalisa isandi = isandi sokufunxa isandi
Isandi esidluliselwa ngesandi = ilahleko yothumelo
Esinye isandi sitsalwa eludongeni kwaye sijike sibe ngamandla obushushu.
Kobu budlelwane bungasentla, akukho nzima ukufumanisa ukuba ukugquma kwesandi kunokuqinisekisa kuphela isandi esincinci esidluliswayo kangangoko kunokwenzeka, kodwa akunyanzelekanga ukuba sibe nesiphumo esihle sokufunxa isandi.
imathiriyeli efunxa isandi
Iimathiriyeli eziqhelekileyo zokufunxa isandi zizinto ezirhabaxa, okanye igama lezenzululwazi yi-acoustic resistance efunxa isandi.Undoqo wezandi zamaza luhlobo lokungcangcazela, xa sithetha ngqo, lushukumo lomoya kwisixokelelwano sesithethi.Xa ukungcangcazela komoya kuhanjiswa kule nto ifunxa isandi, iya kukhululeka kancinci kancinci ngesakhiwo sepore esicolekileyo kwaye siguqulwe sibe ngamandla obushushu.
Xa sithetha ngokubanzi, okukhona izinto ezifunxa isandi zijiyile, kokukhona imingxunya emincinci ikwicala lokusasazwa kwesandi, kwaye kokukhona isiphumo sokufunxa sesiganeko sesandi singcono ngokukhawuleza okanye kwi-engile encinci.
Izinto zokusasaza
Xa isandi senzeke eludongeni, isandi esithile siya kuphuma kwicala lejometri kwaye siqhubeke sisasazeka, kodwa ngokuqhelekileyo le nkqubo ayikho "imbonakalo ekhethekileyo".Ukuba luphawu olufanelekileyo olugqibeleleyo, isandi kufuneka siphume ngokupheleleyo kwicala lejometri emva kokudlula kumphezulu, kwaye amandla kwicala lokuphuma ahambelane nesalathiso sesiganeko.Yonke le nkqubo ayiphelelwa ngamandla, enokuthi iqondwe njengokungabikho kosasazo konke konke, okanye ngokudume ngakumbi njengokubonakaliswa okukhethekileyo kwi-optics.
isixhobo sokukhusela isandi
Ukufakwa kwesandi kunye neempawu zokufunxa isandi semathiriyeli zahlukile.Izinto ezifunxa isandi zihlala zisebenzisa ubume bepore kwizinto eziphathekayo.Nangona kunjalo, esi sakhiwo se-pinhole ngokuqhelekileyo sikhokelela ekugqithiseni kunye nokusasazwa kwamaza omsindo.Nangona kunjalo, ukwenzela ukuthintela isandi ekugqithiseni ngakumbi kwizinto eziphathekayo, kuyimfuneko ukunciphisa isakhiwo somgodi ngokusemandleni kwaye ukwandisa ubuninzi bezinto eziphathekayo.
Ngokuqhelekileyo, ukusebenza kwesandi sokufakelwa kwesandi sezinto zokufakelwa kwesandi kuhambelana nokuxinana kwezixhobo.Ukuthenga izixhobo zokugquma isandi ezixineneyo kunokuphucula ngakumbi ukusebenza kwesandi segumbi.Nangona kunjalo, imathiriyeli yokufakwa kwesandi somgangatho omnye ngamanye amaxesha isenayo imida.Ngeli xesha, unyango lwe-sound-layer ephindwe kabini lunokwamkelwa, kwaye izinto ezongezelelweyo zokuhlamba zingongezwa kwizinto ezimbini zokufakelwa kwesandi.Nangona kunjalo, kufuneka kuqatshelwe ukuba iileya ezimbini zezixhobo zokugquma isandi kufuneka ziphetshwe kangangoko kunokwenzeka ukuba zithathe ubukhulu obufanayo, ukuze kugwenywe ukuphindaphinda ukuphindaphinda okwenzekayo.Ukuba kulwakhiwo lwangempela kunye nokuhlobisa, indlu yonke kufuneka ivalwe isandi kuqala, kwaye emva koko ukufunxa isandi kunye nonyango lokusasaza kufuneka lwenziwe.
