Mapangidwe amawu amalola othamanga kuvala "mahedifoni"

Mapangidwe acoustic amalola othamanga kuvala“mahedifoni”

Ogasiti 6, 2024 # Masewera a Olimpiki a ku Paris #10 mita pakudumphira kumapeto, opambana mendulo zagolide atatu Quan Hong chan ndi Chen Yunxi adakhala pamodzi, matupi awo, akuwoneka mwachilengedwe, akuwonetsa "munthu wamkulu atakhala", mutuwo udavalabe zomvera. Anthu ambiri adanena kuti uku ndikupumula kwa mphamvu zapamwamba. Anthu ena amadabwa: bwanji kuvala mahedifoni podikirira kupuma? Ogwiritsa ntchito pa intaneti ambiri adapereka yankho loyenera, othamanga akudikirira kuti apumule kuti adzipatula pabwalo lamasewera, kukhalabe ndi chidwi, kupumula, kuthetsa kusamvana. Chifukwa chake, potengera ma acoustics architectural acoustics, monga wopanga ma acoustic, ndi mtundu wanji wamapangidwe acoustic wamalo omwe anthu amasonkhana monga mabwalo amasewera omwe angathandizenso othamanga?

Malinga ndi mawonekedwe a thupi la masewera olimbitsa thupi, titha kuthana ndi zovuta zamayimbidwe mwa kuyimitsa choyimitsa phokoso pamalo athyathyathya ndikupanga khoma la matabwa lotulutsa mawu.

Mapangidwe a porous a board-absorbeng board amakwaniritsa zofunikira zapakatikati komanso zotsika pafupipafupi zokomera mawu, zomwe zimatheka pofananiza ndi ma acoustic impedance ndi mawonetseredwe angapo, ma refractions ndi kuchepetsedwa kwa mafunde amawu. Phokosoli likadutsa pamwamba pa bolodi lotengera mawu, mbali ina ya mafunde amamveka, ndipo mbali ina ya mafundewa imalowa pamwamba pa bolodi, kenako imatengedwa ndi porous structural material. mu bolodi lotengera mawu, potsirizira pake mutembenuzire mphamvuzo kukhala mphamvu yaing'ono ya kutentha. Komanso, gawo lapansi la matabwa perforated mbale angathenso kusankha MDF ndi chinyezi-umboni ntchito, kapena galasi magnesium mbale ndi khola chinyezi-umboni ntchito, amene ali amphamvu madzi ntchito, si kophweka dzimbiri, ndi mayamwidwe phokoso. magwiridwe antchito ndi okhazikika.

Denga la masewera olimbitsa thupi ndilo chinsinsi chothandizira kumveka bwino. Choyimitsira phokoso chamlengalenga chimawulula mbali zonse zake kumunda wamawu wamkati popachikidwa, kotero kuti imakhala ndi njira zingapo zokomera mawu. Chotsitsa phokoso chamlengalenga chimaphatikiza mawonekedwe otayirira a thonje lake lamkati lotulutsa mawu ndi kumveka kwa kapangidwe kake kuti atenge phokoso ndikuchepetsa phokoso, lomwe lingafupikitse nthawi yobwereza, kumveketsa bwino kwa mawu, ndikuthetsa vuto la zolakwika zamawu. monga kulunjika kwa mawu ndi mauna.

Mapangidwe amawu omvera ophatikizidwa ndi bolodi lotengera mawu komanso thupi lotulutsa mawu ndikusunga nthawi yapakati pa natatorium pa 2.0s-3.5s, zomwe zimatsimikizira kumveka bwino kwa phokoso la maphunziro amasewera ndi zochitika zamasewera kwambiri. , ndikuthandizira kumveka bwino komanso kumveka bwino kwa malo a osewera ndi omasulira.
