Idizayini ye-acoustic ivumela abasubathi ukuthi bagqoke“ama-headphone”

Agasti 6, 2024 # Imidlalo Yama-Olympic YaseParis #amamitha ayi-10 ekupheleni kwebhodi, abathole izindondo zegolide abathathu u-Quan Hong chan no-Chen Yunxi bahlezi ndawonye, ​​imizimba yabo, ibukeka ngokwemvelo, ikhombisa “indoda enkulu ehlezi”, ikhanda empeleni lisagqoke ama-headphone. Abantu abaningi baphawule ukuthi lokhu ukuxegiswa kwamandla aphezulu. Abanye abantu bayazibuza: kungani ugqoka ama-headphone uma ulinde ikhefu? Abasebenzisi benethiwekhi abaningi banikeze impendulo efanele, abasubathi balinde ukuphumula ukuze bahlukanise umoya wenkundla, bagcine ukugxila, baphumule, banciphise ukungezwani. Ngakho-ke, ngokombono we-architectural acoustics, njengomklami we-acoustic, hlobo luni lomklamo we-acoustic wezindawo ezinokubuthana kwabantu njengezinkundla zemidlalo nazo ezingasiza abasubathi?

Ngokwezici zomzimba zesikhungo sokuzivocavoca, singakwazi ukuxazulula izinkinga ze-acoustic ngokumisa isinqamuleli somsindo endaweni eyisicaba futhi siklame udonga lwepulangwe lokumunca umsindo.

Isakhiwo esinezimbotshana sebhodi lezinkuni elimunca umsindo sihlangabezana nezidingo zokumunca umsindo okuphakathi nendawo nokuphansi, okufezwa ngokufanisa i-acoustic impedance kanye nokucabangisisa okuningi, ukuphikisa kanye nokuncishiswa kwamagagasi omsindo. Lapho igagasi lomsindo lidlula ebusweni bebhodi elimunca umsindo, ingxenye yegagasi lomsindo izobonakala, futhi ingxenye yegagasi lomsindo izongena endaweni engaphezulu ebhodini, bese imuncwa izinto zesakhiwo ezinezimbobo. ebhodini elimunca umsindo, ekugcineni uguqule amandla abe amandla amancane okushisa. Ngaphezu kwalokho, i-substrate yepuleti elinembobo yokhuni ingaphinde ikhethe i-MDF enomsebenzi wokufaka umswakama, noma ipuleti lengilazi le-magnesium elinokuqina okuqinile kokumelana nomswakama, elinokusebenza okuqinile okungangeni manzi, akulula ukugqwala, nokumuncwa kwalo msindo. ukusebenza kuzinzile.

Uphahla lwejimu luyisihluthulelo sokuthuthukisa ukucaca komsindo. Isinqamuli somsindo sendawo sidalula ngokuphelele zonke izingxenye zaso endaweni yomsindo wasendlini ngokulenga, ukuze sibe nezindawo zokuhlangana eziningi ezimunca umsindo. I-spatial sound absorber ihlanganisa ukwakheka okuxekethile kwe-porous yayo yangaphakathi emunca ukotini ne-resonance yesakhiwo ukuze imunce umsindo futhi inciphise umsindo, engafinyeza isikhathi sokuphindaphinda, ithuthukise ukucaca komsindo, futhi ixazulule inkinga yokulimala komsindo. njengokugxilisa umsindo nokunanela.

Idizayini ye-acoustic ehlanganiswe nebhodi elimunca umsindo kanye nomzimba omunca umsindo wesikhala igcina isikhathi esiphakathi nendawo sokuphendula imvamisa ye-natatorium ngo-2.0s-3.5s, okuqinisekisa ukuphakama nokucaca komsindo wokuqeqeshwa kwezemidlalo nemicimbi yezemidlalo ngokwezinga elikhulu. , futhi ithuthukisa ukugcwala komsindo nomuzwa wesikhala wonompempe nabatolika.
