Ibyumba bya Anechoic

Icyumba cya anechoic ni umwanya utagaragaza amajwi.Urukuta rw'icyumba cya anechoic ruzashyirwaho ibikoresho bikurura amajwi hamwe nibintu byiza bikurura amajwi.Kubwibyo, ntihazagaragazwa amajwi yumurongo mubyumba.Icyumba cya anechoic ni laboratoire ikoreshwa cyane mugupima amajwi ataziguye abavuga, ibice byabavuga, na terefone, nibindi. Irashobora gukuraho kwivanga kwijwi ryibidukikije kandi ikagerageza rwose ibiranga igice cyose cyamajwi.Ibikoresho bikurura amajwi bikoreshwa mu cyumba cya anechoic bisaba ko coeffisente yo kwinjiza amajwi irenze 0.99.Mubisanzwe, icyiciro gikurura igikoresho gikoreshwa, kandi wedge cyangwa conical structure ikoreshwa.Ubwoya bw'ikirahuri bukoreshwa nk'ibikoresho bikurura amajwi, kandi ifuro yoroshye nayo irakoreshwa.Kurugero, muri laboratoire ya 10 × 10 × 10m, hashyizweho uruziga rwa 1m z'uburebure bwijwi rwa 1m, kandi umurongo wacyo wo hasi ushobora guhagarara 50Hz.Iyo kwipimisha mucyumba cya anechoic, ikintu cyangwa isoko yijwi ryageragejwe bishyirwa kumurongo wa nylon rwagati cyangwa icyuma.Bitewe nuburemere buke ubu bwoko bwa mesh bushobora kwihanganira, gusa uburemere-bworoheje hamwe nijwi rito ryamajwi bishobora kugeragezwa.
