Lapho ngidla endaweni yokudlela, ngezinye izikhathi kuye kudingeke ngimemeze kwelinye itafula.Ingabe indawo yokudlela enomsindo kangaka ngenxa nje yokuthi thina maShayina siphile saka?angiqinisekile!Kungenzeka ukuthi i-acoustic material ayinamsebenzi.
Izinto ze-acoustic zithinta zonke izici zokuphila.E-United States, kusetshenziswa ingxenye encane yezinto zomculo we-acoustic emkhakheni wokuqoshwa komculo, futhi ezengeziwe zisetshenziswa ekwakhiweni nasekuhlobiseni izindlu, amahhotela, izindawo zokudlela, izakhiwo zamahhovisi, izindawo zokuzivocavoca, njll. Kunezinhlobo ezintathu ezijwayelekile ze izinto zokwakha zasendlini, kodwa ngayinye inezinkinga ezinkulu.
1. Isikhwama esithambile sesipontshi
Lokhu okuqukethwe kuyingozi kakhulu, futhi isifundo esichitha igazi kakhulu kwaba umlilo webha e-Santa Maria, e-Brazil, ngoJanuwari 2019. Lowo mlilo wabulala abantu abangaphezu kuka-200 futhi walimaza amakhulu.Abalimele bagcwele zonke izibhedlela zendawo.Kungabonakala kuvidiyo ebukhoma nezithombe ukuthi umlilo wawumkhulu kakhulu, amalangabi eqe phansi eziningana phezulu, futhi umlilo wathatha amahora ambalwa ngaphambi kokuba ucishwe.I-Los Angeles Times ithe lo mlilo owabulala abantu abaningi kunayo yonke emhlabeni kule minyaka eyishumi edlule.
Ngokophenyo, ibhendi yasekhaya yasebenzisa iziqhumane ukucula e-nightclub ukuze kwakhiwe umoya ngalobo busuku.Mhlawumbe inhlansi ishaye ngephutha udonga lwegwebu elingazwakali.Sabalalisa ngokushesha ophahleni.Isikhulu samaphoyisa aseSanta Maria, uMarcey, sithe igwebu elisophahleni lwe-nightclub liyavutha futhi lingaqeda ama-echoes kuphela futhi ngeke lisetshenziswe njengento yokuvala umsindo.
Ngaphezu kokungaphephile, umphumela wakhe wokumunca umsindo nawo awuzinzile, ngoba isipontshi senziwa ngokulokhu sinyakazisa izinto ezingavuthiwe, sizifudumeze bese sizicindezela ukuze zibumbe.Ngakho-ke, ukuminyana kweqoqo ngalinye lezipontshi kuhlukile.Umphumela wokumunca umsindo nawo uhlukile.
2. Ibhodi le-polyester fiber elimunca umsindo
Izakhiwo zokumunca umsindo zamaphaneli e-polyester fiber abamba umsindo afana nezinye izinto ezimboza.I-coefficient emunca umsindo iyanda ngokunyuka kwemvamisa.I-coefficient emunca umsindo yemvamisa ephezulu inkulu kakhulu.izakhiwo ezimunca umsindo.I-coefficient yokunciphisa umsindo icishe ibe ngu-0.8 kuya ku-1.10, okuyenza ibe umzimba omunca umsindo osezingeni eliphezulu onebhendi yefrikhwensi ebanzi.Futhi le nto ingenziwa ngemibala ehlukahlukene, inhle kakhulu, futhi kulula ukuyifaka.Kodwa-ke, okubi kakhulu kwamaphaneli amunca umsindo we-polyester fiber ukuthi ukumuncwa komsindo we-low-frequency kubi.Ngenxa yesakhiwo esilinganiselwe sempahla yayo, imunca kahle umsindo wemvamisa ephansi, njengomsindo okhiqizwa izinto zikagesi, njengomsindo wokupopa okhiqizwe ama-slipper aphezulu, umsindo wodonga olubangelwa ukudlidliza kwendlu kamakhelwane. , futhi umsindo wokudlidliza okhiqizwa phansi kunzima ukuwuqeda.
3. Amaphaneli okhuni abamba umsindo
Izinkampani eziningi ziya kwamanye amazwe ziyohlola futhi zibone ukuthi izinto ezintsha zokhuni ezisetshenziswa abantu zinhle kakhulu futhi zisebenza kahle, ngakho ziyabuya zizofunda, futhi zifake nezinkuni lapho zihlobisa.Eqinisweni, le nto yokhuni emunca umsindo engaphezulu, isihloko singemuva, okuthinta ngempela umsindo imbobo emunca umsindo ngemuva kwayo.Amabhizinisi asekhaya alandela isibonelo sokufakwa, ngokuvamile kuphela ubuso bezinkuni.Ngaphandle komgodi ngemuva kwayo, yiqiniso, akukho ukukhanga.
