Izinto ze-acoustic zingahlukaniswa zibe izinto ezimunca umsindo kanye nezinto ezivikela umsindo ngokuya ngemisebenzi yazo ehlukene.Inhloso eyinhloko yokumuncwa komsindo ukuxazulula umsindo obangelwa ukubonakaliswa komsindo.Izinto ezimunca umsindo zinganciphisa amandla abonisiwe omthombo womsindo wesigameko, ukuze kuzuzwe umphumela wokwethembeka womthombo womsindo wokuqala.Ukufakwa komsindo ikakhulukazi kuxazulula ukudluliswa komsindo futhi kwenza umzimba oyinhloko uzizwe unomsindo esikhaleni.Izinto zokuvikela umsindo zinganciphisa amandla adlulisiwe omthombo womsindo wesigameko, ukuze kuzuzwe isimo esithule sendawo eyinhloko.
Ukotini omunca umsindo ovumela imvelo uyinto emunca umsindo enezimbotshana.Indlela yokumunca umsindo ukuthi kunenani elikhulu lezimbotshana ezincane ezixhumene ngaphakathi kwempahla.Eceleni kwalezi zimbotshana, amaza omsindo angangena ajule entweni futhi enze ukungqubuzana nokokusebenza ukuze aguqule amandla omsindo abe amandla okushisa.Izici zokumuncwa komsindo zezinto ezimunca umsindo eziyizimbotshana ukuthi i-coefficient yokumunca umsindo iyanda kancane kancane ngokunyuka kwamafrikhwensi, okusho ukuthi ukumuncwa kwefrikhwensi ephansi akufani nokumuncwa kwefrikhwensi ephezulu.Izimo ezidingekayo zokumuncwa komsindo wezinto ezinama-porous yilezi: impahla inenani elikhulu lama-voids, ama-voids axhumene, futhi ama-pores angena ekujuleni kwento.
Omunye wemibono eyiphutha ukuthi izinto ezinezindawo ezimaholoholo zinezakhiwo zokumunca umsindo, kodwa azinjalo.Ukungaqondi kahle kwesibili ukuthi izinto ezinezimbobo eziningi zezinto ezibonakalayo, njenge-polystyrene, i-polyethylene, i-valve-cell polyurethane, njll., zinezakhiwo ezinhle zokumunca umsindo.Ukungqubuzana kokudlidliza kwangaphakathi kwento, ngakho-ke i-coefficient yokumuncwa komsindo incane.
