Ibyumba bya Anechoic

Icyumba cy’amajwi kitagira ijwi ni ahantu hatagaragara amajwi. Inkuta z’icyumba cy’amajwi zizaba zirimo ibikoresho bikurura amajwi bifite imiterere myiza yo kwakira amajwi. Kubwibyo, nta rumuri rw’amajwi ruzaba ruri mu cyumba. Icyumba cy’amajwi kitagira ijwi ni laboratwari ikoreshwa byumwihariko mu gupima amajwi y’indangururamajwi, amajwi, amajwi yo mu matwi, nibindi. Ishobora gukuraho ukwivanga kw’amajwi mu bidukikije no kugerageza burundu imiterere y’amajwi yose. Ibikoresho bikurura amajwi bikoreshwa mu cyumba cy’amajwi kitagira ijwi bisaba ko amajwi arenga 0.99 afatwa. Muri rusange, hakoreshwa urwego rufata amajwi, kandi imiterere y’amajwi cyangwa imiterere y’amajwi ikunze gukoreshwa. Ubwoya bw’ikirahure bukoreshwa nk’ibikoresho bikurura amajwi, kandi ifuro ryoroshye naryo rikoreshwa. Urugero, muri laboratwari ya 10 × 10 × 10 m, agace gafata amajwi ka metero 1 gashyirwa ku mpande zombi, kandi umuvuduko wabwo wo gukata amajwi ugabanuka ushobora kugera kuri 50Hz. Mu gihe cyo gupima mu cyumba kidafite ijwi, ikintu cyangwa isoko y'amajwi bigomba kugeragezwa bishyirwa ku muyoboro wa nylon wo hagati cyangwa ku muyoboro w'icyuma. Bitewe n'uburemere buke ubwo bwoko bw'umuyoboro bushobora kwihanganira, ni amasoko y'amajwi yoroheje n'ay'ingano nto gusa ashobora kugeragezwa.
