Amagumbi e-Anechoic

I-anechoic chamber yindawo engabonisi isandi. Iindonga ze-anechoic chamber ziya kugalelwa ngezinto ezifunxa isandi ezineempawu ezilungileyo zokufunxa isandi. Ke ngoko, akuyi kubakho kubonakaliswa kwamaza esandi kwigumbi. I-anechoic chamber yilabhoratri esetyenziselwa ngokukodwa ukuvavanya isandi esithe ngqo sezithethi, iiyunithi zezithethi, ii-earphone, njl. Ingasusa ukuphazamiseka kwee-echoes kwindawo kwaye ivavanye ngokupheleleyo iimpawu zeyunithi yesandi iyonke. Izinto ezifunxa isandi ezisetyenziswa kwigumbi le-anechoic zifuna i-coefficient yokufunxa isandi engaphezulu kwe-0.99. Ngokubanzi, kusetyenziswa umaleko wokufunxa i-gradient, kwaye izakhiwo ze-wedge okanye ze-conical zihlala zisetyenziswa. Uboya beglasi busetyenziswa njengezinto ezifunxa isandi, kwaye kusetyenziswa ne-foam ethambileyo. Umzekelo, kwilabhoratri ye-10×10×10m, i-wedge efunxa isandi ende eyi-1m ibekwa kwicala ngalinye, kwaye i-frequency yayo yokusika i-frequency ephantsi inokufikelela kwi-50Hz. Xa kuvavanywa kwigumbi elingena-anechoic, into okanye umthombo wesandi oza kuvavanywa ubekwa kwi-mesh ye-nylon ephakathi okanye kwi-mesh yentsimbi. Ngenxa yobunzima obulinganiselweyo obunokuthwala olu hlobo lwe-mesh, kuphela imithombo yesandi esilula nesincinci enokuvavanywa.
