Isahani ifunze ya aluminiyumu ifuro ikozwe muburyo bukomeye bwo gufata amajwi nyuma yo kuvura (φ2mm umwobo, igipimo cyo gutobora 1 ~ 3%), ifite imikorere myiza yo kwinjiza amajwi, kandi igipimo cyo kwinjiza amajwi gishobora kugera kuri 60% ~ 90%. Kuberako ubuso bwibi bikoresho butagira indege, ifite ubuso buhebuje bwo gukwirakwiza amajwi yerekana imikorere, kandi mugihe kimwe cyasobekeranye na Helmholtz resonance absorber amajwi yo kwinjiza amajwi kugirango igabanye amajwi menshi. Byongeye kandi, ahantu h’ubushuhe, ibikoresho bisanzwe bikurura amajwi bikurura ubuhehere kandi bikaguka, kandi coefficente yo kwinjiza amajwi iragabanuka cyane, mugihe ibikoresho bya aluminiyumu bifata amazi, kandi igipimo cyayo cyo kwinjiza amajwi ntigabanuka.
Nkuko umubyimba wikirere wiyongera kuva kuri 0mm ukagera kuri 90mm, inshuro nyamukuru yo kwinjiza amajwi igabanuka kuva 2000Hz ikagera kuri 300Hz. Iyo umubyimba wikirere ari 10, 30, 60, 90mm, inshuro nyamukuru yikigereranyo cyo kwinjiza amajwi ni 1000Hz, 500Hz, 400Hz, 300Hz. Ukurikije urusaku rwo gukwirakwiza urusaku rwerekana ifuro igipimo cyo kwinjiza amajwi inyuma yuburebure bwikirere. Inshuro nyamukuru y urusaku rwatewe nimodoka mumihanda minini, umugezi wo hepfo yumugezi hamwe nu mwobo wo mu mazi ni hafi ya 400Hz, akaba ari urusaku ruke, bityo rero ikirere cyumuyaga wa 60mm kikaba gishyizwe inyuma ya plaque aluminium acoustic ya plaque yinzitizi yumuhanda, epfo yinzuzi na submarine tunnel acoustic urukuta, rufite ingaruka nziza zo kugabanya urusaku. Urusaku rwa gari ya moshi ni urusaku ruciriritse ruri hejuru ya 1000Hz, kandi ikirere cya mm 20 z'uburebure gishyirwa inyuma ya panne ya aluminiyumu ifata amajwi, ifite ingaruka nziza zo kugabanya urusaku.
