Izixhobo ze-acoustic zinokwahlulwa zibe zizixhobo ezifunxa isandi kunye nezixhobo zokukhusela isandi ngokwemisebenzi yazo eyahlukileyo.Injongo ephambili yokufunxa isandi kukusombulula ingxolo ebangelwa kukubonakalisa isandi.Izinto ezifunxa isandi zinokuthoba amandla abonakalisiweyo kumthombo wesandi sesiganeko, ukuze kuphunyezwe umphumo wokuthembeka komthombo wesandi sokuqala.Ukufakwa kwesandi ikakhulu kusombulula ukuhanjiswa kwesandi kwaye kwenza ukuba umzimba oyintloko uzive unengxolo esikhaleni.Isixhobo sokugquma isandi sinokuthomalalisa amandla adlulisiweyo omthombo wesandi sesiganeko, ukuze kufezekiswe imeko yokuzola yendawo ephambili.
Umqhaphu ofunxa isandi esisingqongileyo sisimathiriyeli esifunxa isandi.Indlela yokufunxa isandi kukuba kukho inani elikhulu lee pores ezincinci ezidibeneyo ngaphakathi kwemathiriyeli.Ecaleni kwezi pores, amaza esandi anokungena nzulu kwizinto eziphathekayo kwaye avelise ukungqubuzana kunye nezinto eziphathekayo ukuguqula amandla omsindo abe ngamandla obushushu.Iimpawu zokufunxa isandi sezixhobo zokufunxa isandi kukuba i-coefficient yokufunxa isandi ngokuthe ngcembe inyuka ngokunyuka kwamaza, nto leyo ethetha ukuba ukufunxa okuphantsi akulunganga njengokufunxa kwamaza.Iimeko eziyimfuneko zokufunxa isandi sezinto ezinqabileyo zezi: izinto eziphathekayo zinenani elikhulu le-voids, i-voids idibeneyo, kwaye i-pores ingena nzulu kwizinto eziphathekayo.
Enye yeengcinga ezingezizo kukuba izixhobo ezinemigangatho erhabaxa zineempawu zokufunxa isandi, kodwa azinjalo.Ukungaqondi kakuhle okwesibini kukuba izinto ezinezimbobo ezininzi kwizinto eziphathekayo, ezifana ne-polystyrene, i-polyethylene, i-valve-cell polyurethane, njl., zineempawu ezintle zokufunxa isandi.I-friction ye-vibration yangaphakathi yezinto, ngoko i-coefficient yokufunxa isandi incinci.
