Ka tsoelo-pele e potlakileng ea mokhatlo oa batho, batho ba ba le litlhoko tse eketsehileng tsa nama le tsa moea, ’me ba hahamalla tikoloho ea lehae e mabothobotho ea ho qetela. Kahoo batho ba reka li-stereo tsa maemo a holimo, ba tšepile ho thabela ’mino lapeng; reka liprojeke, ka tšepo ea ho shebella lifilimi betheng; reka treadmill, ka tšepo ea ho ikoetlisa ntle le ho tloha lapeng. Ha batho ba ntse ba tsoela pele ho fallela matlong a bona, ho baka bothata bo boholo ka ho fetisisa - lerata. Kahoo, ntoa ea "lerata" ea ho itšireletsa e ile ea qala.
Hajoale, lisebelisoa tse tloaelehileng tse monyang molumo le tse fokotsang lerata 'marakeng li kenyelletsa fiber ea polyester, boea ba khalase, foam ea polyurethane, le lisebelisoa tsa tšepe tse foam. E le thepa ea aluminium e theko e tlaase le e sebetsang hantle ka ho fetisisa sehlopheng sa eona, bokhoni ba eona ba ho koala molumo le ho fokotsa lerata ke makhetlo a 7-10 a foam ea polyurethane, fiber ea khalase le aluminium ea khekhe ea linotsi. Ha e sebelisoa ho literene tsa lebelo le phahameng le liphanele tsa likoloi, ho koala molumo ho haufi le 30dB. Ho ea ka lintlha tsa tlhahlobo, boemo ba ho koala molumo oa li-skrini tse tloaelehileng tsa molumo bo ka fokotsoa feela ka 5dB, 'me lisebelisoa tsa aluminium tse foam li ka fokotsoa ka 10-20dB. Ho latela tlhahlobo, ho bontšoa hore:
| Lintho tse bonahalang | Tlhaloso | Ntho ea ho Fokotsa Lerata / Bongata ba ho Insulation ea Molumo |
| Foam ea polyurethane | 35mm botenya | Coefficient ea ho fokotsa lerata ke 0.85NRC |
| Foam ea polyurethane | 35mm botenya | Ho koala molumo ke 23dB |
| Lisebelisoa tsa aluminium foam | 20 mm botenya | Coefficient ea ho fokotsa lerata ke 0.9NRC |
| Lisebelisoa tsa aluminium foam | 20 mm botenya | Tšireletso ea molumo ke 30dB |
Ka nts'etsopele ea indasteri ea foam ea aluminium, foam ea aluminium e sebelisoa masimong a mangata le ho feta ka lebaka la ho monya molumo o phahameng le ho fokotsa lerata le thepa e amanang le eona, joalo ka mekoallo ea molumo oa litsela, phokotso ea lerata la kotopo ea litsela, phokotso ea lerata la kotopo ea likepe tse tsamaeang ka tlas'a metsi, le likotopo tsa kotopo; Mabota a matamo a ho sesa a monyang molumo; mokhabiso oa ka hare oa libaka tsa boithabiso; tlhahiso ea aluminium ea foam ea literaka, likoloi tsa baeti le li-mufflers tsa koloi; tlhahiso ea foam aluminium ea ho haha lisela tse monyang molumo, tse kang li-studio tsa ho rekota, likamore tsa ho rekota, liholo tsa likonsarete, liholo tsa likopano, libaka tsa lipapali le libaka tse ling, li na le ts'ebetso e babatsehang.
