Amagumbi ane-Anechoic

I-anechoic chamber yindawo engabonakalisi sandi.Iindonga zegumbi le-anechoic ziya kuhlanjululwa kunye nezixhobo zokukhupha isandi kunye neempawu ezintle zokukhupha isandi.Ngoko ke, akuyi kubakho kubonakaliswa kwamaza omsindo kwigumbi.Igumbi le-anechoic liyibhubhoratri esetyenziselwa ukuvavanya isandi esithe ngqo sezithethi, iiyunithi zesithethi, ii-earphones, njl.Izinto ezifunxa isandi ezisetyenziswe kwigumbi le-anechoic zifuna i-coefficient yokufunxa isandi esikhulu kune-0.99.Ngokuqhelekileyo, i-gradient absorbing layer isetyenziswa, kwaye i-wedge okanye izakhiwo ze-conical zisetyenziswa ngokuqhelekileyo.Uboya beglasi busetyenziswa njengemathiriyeli efunxa isandi, kwaye nogwebu oluthambileyo luyasetyenziswa.Ngokomzekelo, kwi-laboratory ye-10 × 10 × 10m, i-wedge ye-1m ubude efunxa isandi ibekwe kwicala ngalinye, kwaye i-low-frequency cut-off frequency inokufikelela kwi-50Hz.Xa uvavanya kwigumbi le-anechoic, into okanye umthombo wesandi oza kuvavanywa ubekwe kumnatha wenylon ephakathi okanye intsimbi yentsimbi.Ngenxa yobunzima obulinganiselweyo obunokuthi olu hlobo lwe-mesh luthwale, kuphela ubunzima bokukhanya kunye nemithombo yesandi esincinci inokuvavanywa.
