Uwitekakugabanya urusakucoefficient (mubisanzwe yitwa NRC) numubare umwe wumubare wa 0.0-1.0, usobanura impuzandengo yo kwinjiza amajwi yibikoresho.Uwitekakugabanya urusakucoefficente ni impuzandengo ya Sabine amajwi yo kwinjiza amajwi apimye kuri 250, 500, 1000, na 2000 Hz.

Agaciro ka 0.0 bivuze ko ikintu kidahuza amajwi yo hagati, ariko kigaragaza imbaraga zijwi.Ibi birasobanutse kuruta kugerwaho kumubiri: niyo inkuta zibyibushye cyane zizahuza amajwi, nakugabanya urusakucoefficient irashobora kuba 0.05.

Ibinyuranye, coefficente yo kugabanya urusaku rwa 1.0 isobanura ko ubuso bwa acoustic (muri sabin nkigice) butangwa nibikoresho bingana nubuso bwacyo bubiri-buringaniye.Uru rwego ni ibintu bisanzwe kubikoresho byijimye bikurura amajwi (nkibikoresho bya santimetero 2 z'ubugari bipfunyitse fiberglass panel).Ibi bikoresho birashobora kugera ku gipimo cyo kugabanya urusaku agaciro karenze 1.00.Iyi ni inenge muburyo bwo gukora ibizamini, kandi ni imbogamizi yubusobanuro bwa acoustician bwibisobanuro bya kare aho kuba ibiranga ibikoresho ubwabyo.

Impamvu yo kugabanya urusaku ikoreshwa cyane mugusuzuma imikorere rusange ya acoustic ya plafond ya acoustic, ibice, banneri, ecran y'ibiro, hamwe nurukuta rwa acoustic.Rimwe na rimwe bikoreshwa mugusuzuma ibyateganijwe hasi.Ariko,kugabanya urusakuni gusakugabanya urusaku, irashobora kugabanya neza ingaruka zurusaku kubantu, ariko ntishobora gucecekesha amajwi rwose.Biracyakenewe gushakisha ibikoresho byumwuga bikurura amajwi.

Nibihe bikoresho byo hejuru bya NRC bikurura amajwi?Minerval fibre plaque na fibre yububiko nibikoresho byiza byo kwinjiza amajwi kandikugabanya urusaku.Nrc yububiko bwa fibre minerval muri rusange igera kuri 0.5, kandi nrc yibibaho bya fiberglass irashobora kugera kuri 0.9-1.0.Turashobora gushiraho ibikoresho bikwiye kugirango dukurikije ibidukikije bitandukanye.
