Ngokombono wokuvikelwa kwemvelo, yonke “imisindo engadingeki” ethinta ukufunda okujwayelekile kwabantu, umsebenzi, nokuphumula ezimweni ezithile ngokuhlangene kubizwa ngokuthi umsindo.Okufana nokushiswa kwemishini, ukushaywa kwezimoto ezihlukahlukene, umsindo wabantu nemisindo ehlukahlukene ezumayo, njll., konke kubizwa ngokuthi umsindo.Ngokuthuthuka kokukhiqizwa kwezimboni, ezokuthutha, nokwakhiwa kwamadolobha, kanye nokwanda kokuminyana kwabantu, ukwanda kwezinsiza zasendlini (amathelevishini, njll.), umsindo wemvelo uye waba mubi kakhulu, futhi uye waba yingozi enkulu emphakathini ukuthi kungcolisa indawo yenhlalo yabantu.Ucwaningo luye lwathola ukuthi umsindo ongaphezu kwama-decibel angu-85 uzokwenza abantu baphatheke kabi, abantu bazizwe benomsindo, futhi ngenxa yalokho abakwazi ukugxilisa ingqondo emsebenzini, okuzophumela ekwehliseni ukusebenza kahle komsebenzi.

Ngakho-ke, abantu badinga umkhiqizo ophezulu omunca umsindo ukuze banciphise ingxenye yomsindo futhi bazizwe benethezekile.Imikhiqizo emunca umsindo ephezulu i-mineral fibre ceiling board, i-fiber glass ceiling board, i-rock wool ceiling board, njll. Izinto ezimunca umsindo zihlukaniswa kakhulu zibe uhlobo lwe-microporous kanye nohlobo lwefayibha.Awukho umehluko obalulekile phakathi kwabo.Umgomo wokumuncwa komsindo uwukushiya isiteshi esifinyeleleka kalula somsindo, isiteshi esakhiwe izimbobo ezincane ezingenakubalwa ezixhunywe ndawonye, ​​noma imicu engenakubalwa eyeqiwe.Ahlanganiswe ndawonye ukuze akhe izikhala ezincane ezingenakubalwa, kodwa lapho umsindo usungenile, awukwazi ukuphuma.Ngenxa yokuthi iphasishi lingcolile futhi lide, umsindo ubhoboza bese uphahlazeka kwesokunxele nakwesokudla.Kule nqubo, kancane kancane idla amandla futhi inomphumela wokumuncwa komsindo.Imisindo yamafrikhwensi ahlukene idonswa ezimeni ezahlukene.Imisindo yefrikhwensi ephezulu inamaza amafushane futhi ingamuncwa kalula, kuyilapho imisindo yefrikhwensi ephansi inamaza amade futhi ingangena kalula izithiyo.Ngemisindo ye-low-frequency, akunzima nje ukufaka umsindo, kodwa futhi kunzima ukumunca.Akufani nomsindo wemvamisa ephezulu ozoshayisa uphinde uphume eziteshini ezincane eziminyene, kodwa ozohambahamba kalula.Kodwa inqobo nje uma ujiya into emunca umsindo ibe sezingeni elithile, ungakwazi ukumunca amaza aphansi angaphezu kuka-130Hz.
