Hamwe niterambere ryihuse ryumuryango wabantu, abantu bafite byinshi bakeneye kandi byumubiri nibyumwuka, kandi bakurikirana urugo rwiza. Abantu rero bagura stereyo zohejuru, bizeye ko bazishimira umuziki murugo; gura umushinga, wizeye kureba firime muburiri; gura inzira, wizeye gukora siporo utavuye murugo. Mugihe abantu bimura ibikoresho byinshi mumazu yabo, byanze bikunze bitera ikibazo kinini - urusaku. Rero, urugamba rwo kwirwanaho "urusaku" rwatangiye.
Kugeza ubu, ibikoresho bisanzwe bikurura amajwi kandi bigabanya urusaku ku isoko birimo fibre polyester, ubwoya bw'ikirahure, ifuro rya polyurethane, hamwe n'ibikoresho by'icyuma. Nkibikoresho bihenze cyane kandi byorohereza imikorere ya aluminiyumu ya fumu mu cyiciro cyayo, uburyo bwayo bwuzuye bwo gukwirakwiza amajwi no kugabanya urusaku bikubye inshuro 7-10 za polyurethane ifuro, fibre yikirahure, na aluminiyumu yubuki. Iyo ushyizwe muri gari ya moshi yihuta hamwe na paneli yimodoka, insulasiyo y amajwi iba hafi 30dB. Dukurikije imibare yikizamini, urwego rwamajwi rusanzwe rwamajwi rushobora kugabanuka gusa 5dB, naho ibikoresho bya aluminiyumu ya fumu birashobora kugabanukaho 10-20dB. Ukurikije ikizamini, herekanwa ko:
| Ibikoresho | Ibisobanuro | Kugabanya Urusaku Ikintu / Umubare w'amajwi |
| Polyurethane ifuro | Uburebure bwa 35mm | Coefficient yo kugabanya urusaku ni 0.85NRC |
| Polyurethane ifuro | Uburebure bwa 35mm | Gukwirakwiza amajwi ni 23dB |
| Ibikoresho bya aluminium | Uburebure bwa 20mm | Coefficient yo kugabanya urusaku ni 0.9NRC |
| Ibikoresho bya aluminium | Uburebure bwa 20mm | Gukoresha amajwi ni 30dB |
Hamwe no guteza imbere inganda za aluminiyumu, ifuro ya aluminiyumu ikoreshwa mu mirima myinshi kandi myinshi bitewe no kwinjiza amajwi kwinshi no kugabanya urusaku hamwe n’ibintu bifitanye isano, nk'inzitizi z’amajwi yo mu muhanda, kugabanya urusaku rw’imihanda, kugabanya urusaku rw’amazi yo mu mazi, hamwe n’imiyoboro ya tunnel; Urukuta rukurura amajwi y'ibidendezi byo koga; imitako yimbere yimyidagaduro; ifuro ya aluminium amajwi hasi; ifuro rya aluminiyumu ikora amakamyo, imodoka zitwara abagenzi hamwe n’imodoka zitwara abagenzi; ifuro rya aluminiyumu yubaka inyubako zikurura amajwi, nka sitidiyo zifata amajwi, ibyumba byitirirwa, ibyumba by’ibitaramo, inzu zinama, ibibuga by'imikino nizindi nzego, bifite imikorere myiza.
