Kubva pakuona kwekuchengetedzwa kwezvakatipoteredza, “manzwi asingadikanwi” ose anokanganisa kudzidza kwevanhu, basa, uye kuzorora mune mamwe mamiriro ezvinhu anounganidzwa pamwe chete seruzha.Zvakadai sekupiswa kwemichina, muridzo wemotokari dzakasiyana-siyana, ruzha rwevanhu uye ruzha rwakasiyana-siyana rwakangoerekana rwavapo, nezvimwewo, zvose zvinonzi ruzha.Nekuvandudzwa kwekugadzirwa kwemaindasitiri, zvekufambisa, uye kuvakwa kwemadhorobha, pamwe nekuwedzera kwehuwandu hwevanhu, kuwedzera kwenzvimbo dzemumba (terevhizheni, nezvimwewo), ruzha rwezvemamiriro ekunze rwave kuwedzera zvakanyanya, uye yave njodzi huru yeruzhinji iyo inosvibisa magariro evanhu.Ongororo dzakawana kuti ruzha runopfuura madecibel makumi masere neshanu ruchaita kuti vanhu vagumbuke, vanhu vachanzwa ruzha, uye naizvozvo havagoni kuisa pfungwa pabasa, zvichiita kuti basa riderere.
Naizvozvo, vanhu vanoda chigadzirwa chepamusoro-inobata ruzha kuderedza chikamu cheruzha uye kunzwa kugadzikana.Zvigadzirwa zvepamusoro zvinotora ruzha ndeye mineral fiber sirin board, faibha girazi sirin'i board, rock wool sirin board, etc. Zvishandiso zvinotora ruzha zvinonyanya kukamurwa kuita microporous type uye fiber type.Hapana musiyano unokosha pakati pavo.Nheyo yekutorwa kweruzha ndeyekusiya nzira inosvikika yeruzha, chiteshi chinoumbwa nemaburi madiki asingaverengeki akabatana pamwechete, kana asingaverengeki mafiber akayambuka.Dzinosanganiswa pamwe chete kuti dziumbe maburi madiki asingaverengeki, asi kana ruzha rwangopinda, harungabudi.Nemhaka yokuti nzira yacho yakanyanyisa kuipa uye yakareba, ruzha runoputika uye runopwanya kuruboshwe nekurudyi.Mukuita izvi, zvishoma nezvishoma inoshandisa simba uye ine mhedzisiro yekutorwa kwenzwi.Mitsindo yemafrequency akasiyana inotorwa mumamiriro akasiyana.Manzwi e-high-frequency ane mawavelength mapfupi uye anogona kubatwa zviri nyore, ukuwo manzwi akaderera ane mawavelength akareba uye anogona kupinda zvipingamupinyi zviri nyore.Kune yakaderera-frequency manzwi, hazvina kuoma chete kuisa insulate ruzha, asi zvakare zvakaoma kubata.Izvo hazvina kufanana ne-high-frequency ruzha iyo inorovera mukati nekubuda mumatanho madiki madiki, asi inotenderera zviri nyore.Asi chero iwe uchinge wakakora iyo inonzva-inzwi zvinhu kune imwe nhanho, unogona kutora yakaderera frequencies pamusoro pe130Hz.
