Amakamelo ane-Anechoic

I-anechoic chamber iyisikhala esingawuvezi umsindo. Izindonga zekamelo le-anechoic zizobe zigandaywe ngezinto ezibamba umsindo ezinezakhiwo ezinhle ezibamba umsindo. Ngakho-ke, ngeke kube khona ukubonakaliswa kwamagagasi omsindo ekamelweni. Igumbi le-anechoic liyilabhorethri esetshenziswa ngokukhethekile ukuhlola umsindo oqondile wezipikha, amayunithi esipikha, ama-earphone, njll. Ingaqeda ukuphazamiseka kwama-echoes endaweni futhi ihlole ngokuphelele izici zayo yonke iyunithi yomsindo. Into emunca umsindo esetshenziswa egumbini le-anechoic idinga i-coefficient yokumunca yomsindo enkulu kuno-0.99. Ngokuvamile, kusetshenziswa ungqimba olumunca i-gradient, futhi i-wedge noma izakhiwo ze-conical zivame ukusetshenziswa. Uboya bengilazi busetshenziswa njengezinto ezimunca umsindo, kanti negwebu elithambile liyasetshenziswa. Isibonelo, elabhorethri engu-10×10×10m, i-wedge emunca umsindo engu-1m ubude ibekwe ohlangothini ngalunye, futhi imvamisa yayo yokusika imvamisa ephansi ingafinyelela ku-50Hz. Lapho kuhlolwa ekamelweni le-anechoic, into noma umthombo womsindo ozohlolwa ubekwa kumanetha enayiloni amaphakathi noma anezikhala zensimbi. Ngenxa yesisindo esilinganiselwe lolu hlobo lwe-mesh olungasithwala, imithombo yomsindo enesisindo esincane nevolumu encane kuphela engahlolwa.
