Nekukura kunokurumidza kwenzanga yevanhu, vanhu vanova nezvakawanda uye zvinodikanwa zvenyama nezvemweya, uye vanoronda mhoteredzo yekupedzisira yemusha yakanaka. Saka vanhu vanotenga mastereo epamusoro, vachitarisira kunakidzwa nemimhanzi kumba; tenga mapurojekita, uchitarisira kuona mafirimu pamubhedha; tenga matreadmill, uchitarisira kurovedza muviri usingabve pamba. Sezvo vanhu vanofambisa zvivakwa zvakanyanya mudzimba dzavo, zvinokonzeresa dambudziko guru - ruzha. Saka, "ruzha" hondo yekudzivirira yakatanga.
Parizvino, zvinhu zvakajairika zvinotora ruzha uye zvinoderedza ruzha pamusika zvinosanganisira polyester fiber, girazi shinda, polyurethane furo, uye furo simbi zvinhu. Seyakanyanya kudhura uye inoshanda-inoshamwaridzika aluminium furo zvinhu mukirasi yayo, yakazara yekuvharisa ruzha uye kugona kuderedza ruzha i7-10 nguva ye polyurethane furo, girazi faibha, uye huchi aluminium. Kana yaiswa kuzvitima zvinomhanya zvakanyanya uye mapaneru emotokari, iyo yekuvharira inzwi iri pedyo ne30dB. Zvinoenderana nedhata rekuyedza, iyo ruzha rwekuvharidzira mwero weakajairwa ruzha zviratidziro anogona chete kudzikiswa ne5dB, uye furo aluminium zvinhu zvinogona kudzikiswa ne10-20dB. Maererano nemuedzo, zvinoratidzwa kuti:
| Material | Tsanangudzo | Noise Reduction Factor / Nhamba yeInzwi Insulation |
| Polyurethane foam | 35mm gobvu | Ruzha rwekuderedza coefficient i0.85NRC |
| Polyurethane foam | 35mm gobvu | Insulation yenzwi ndeye 23dB |
| Aluminium foam zvinhu | 20mm gobvu | Ruzha rwekuderedza coefficient i 0.9NRC |
| Aluminium foam zvinhu | 20mm gobvu | Insulation yenzwi i30dB |
Nekuvandudzwa kwealuminium foam industrialization, aluminium foam inoshandiswa muminda yakawanda uye yakawanda nekuda kwekukwirira kwayo kwekurira uye kuderedza ruzha uye zvinhu zvine hukama, zvakadai sezvipingamupinyi zvemugwagwa, kuderedza ruzha rwemigwagwa, kuderedza ruzha rwepasi pemvura, uye tunnel vents; Masvingo emadziva ekutuhwina anotora ruzha; kushongedzwa kwemukati kwenzvimbo dzevaraidzo; furo aluminium ruzha rwekudzivirira pasi; foam aluminium kugadzirwa kwemarori, mota dzevafambi uye mota mufflers; foam aluminiyamu kugadzirwa kwekuvaka-inotora-inobata linings, senge masitudiyo ekurekodha, dubbing makamuri, makonzati horo, horo dzemisangano, Nzvimbo dzeMitambo nemimwe minda, zvine mashandiro akanaka.
