Mwinamwake mkokomo wa sitima yakale yomwe ikudutsa mu kanemayo ingadzutse mosavuta kukumbukira kwathu ubwana, monga ngati kunena nkhani zakale.
Koma ngati phokoso lamtunduwu mulibe m'mafilimu, koma nthawi zambiri limawonekera kunyumba kwathu, mwinamwake "chikumbukiro chaubwana" ichi chimasanduka mavuto osatha nthawi yomweyo. Phokoso losasangalatsali ndi phokoso.
Phokoso silimangosokoneza maloto a anthu, koma chofunika kwambiri, chilengedwe chaphokoso cha nthawi yayitali chingayambitse kuwonongeka kosasinthika kwa physiology ndi psychology ya anthu, ndipo ndi chimodzi mwazinthu zofunika kwambiri zowonongeka m'madera amakono.
Kuchepetsa phokoso komanso kutsekereza mawu kwakhala kofunika kwambiri kwa anthu.
Nthawi zambiri, zinthu zomwe zimakhudza kuchuluka kwa phokoso zimaphatikizanso kuchuluka kwa gwero la mawu komanso mtunda pakati pa ma frequency a audio ndi gwero la mawu.
Pankhani yakuti voliyumu, mafupipafupi omvera ndi mtunda pakati pa gwero la phokoso ndi munthuyo samasintha mosavuta, mwa kulimbikitsa chotchinga cha thupi - phokoso lotsekemera la zitseko ndi mazenera, kufalikira kwa phokoso kumatsekedwa momwe mungathere, potero. kupanga osangalatsa komanso omasuka chilengedwe.
Phokoso limakhala losasangalatsa mwakuthupi kapena m'maganizo, losasangalatsa, losasangalatsa, losafunidwa, kapena lokwiyitsa, losavomerezeka kwa iwo omwe amalimva, lomwe limakhudza zokambirana za anthu kapena kuganiza, ntchito, kuphunzira, ndi kupumula phokoso la.
Khutu la munthu limamva pafupipafupi kuti limveke ndi pafupifupi 20Hz ~ 20kHz, ndipo gawo lapakati pa 2kHz ndi 5kHz ndilo gawo lovuta kwambiri la khutu la munthu. Kutsika kwambiri komanso kumveka kwamphamvu kwambiri kumatha kuyambitsa kusamva bwino.
Voliyumu yabwino kwambiri ndi 0-40dB. Chifukwa chake, kuyang'anira malo athu okhalamo komanso momwe timagwirira ntchito momveka bwino m'derali kumatha kupititsa patsogolo chitonthozo mwachindunji komanso mwachuma.
Phokoso lotsika kwambiri limatanthawuza phokoso la 20 ~ 500Hz, maulendo a 500Hz ~ 2kHz ndi mafupipafupi apakati, ndipo maulendo apamwamba ndi 2kHz ~ 20kHz.
M'moyo watsiku ndi tsiku, ma air-conditioning compressor, sitima, ndege, injini zamagalimoto (makamaka pafupi ndi misewu ndi ma viaducts), zombo, zikepe, makina ochapira, mafiriji, ndi zina zambiri zimakhala phokoso lotsika, pomwe nyanga ndi mluzu wamagalimoto. , zida zoimbira, kuvina kwapang'onopang'ono, kuuwa kwa agalu, zowulutsira kusukulu, zolankhula, ndi zina zambiri.
Phokoso lotsika kwambiri limakhala ndi mtunda wautali wotumizira, mphamvu zolowera mwamphamvu, ndipo sizisintha kwambiri ndi mtunda, womwe ndi wovulaza kwambiri thupi laumunthu.
Phokoso lapamwamba kwambiri limakhala ndi vuto lolowera, ndipo lidzachepetsedwa kwambiri pamene mtunda wofalitsa ukuwonjezeka kapena kukumana ndi zopinga (mwachitsanzo, pa kuwonjezeka kwa mamita 10 pa mtunda wofalitsa wa phokoso lapamwamba, phokoso lidzachepetsedwa ndi 6dB).
Voliyumu ndiyomwe imamveka bwino kwambiri. Voliyumu imayesedwa ndi ma decibel (dB), ndipo voliyumu yozungulira yomwe ili pansi pa 40dB ndiye malo abwino kwambiri.
Ndipo kuchuluka kopitilira 60dB, anthu amatha kumva kusapeza bwino.
Ngati voliyumuyo ipitilira 120dB, zimangotenga mphindi imodzi kuti khutu la munthu likhale logontha kwakanthawi.
Kuonjezera apo, mtunda wa pakati pa gwero la phokoso ndi munthuyo umakhudzanso mwachindunji momwe munthuyo amaonera phokoso. Kutalikira kwa mtunda, kutsika kwa voliyumu.
Komabe, phokoso lotsika kwambiri, zotsatira za mtunda pakuchepetsa phokoso sizikuwonekera.
Pamene sikungatheke kusintha zambiri ku malo omwe ali ndi cholinga, kungakhale kusankha kwanzeru kusintha pakhomo ndi zenera zapamwamba, ndikudzipatsa nyumba yamtendere ndi yokongola.
Zitseko ndi mawindo abwino amatha kuchepetsa phokoso lakunja ndi 30dB. Kupyolera mu kasinthidwe kophatikizana kwa akatswiri, phokoso likhoza kuchepetsedwa kwambiri.
Galasi ndi gawo lofunika kwambiri lomwe limakhudza kutsekemera kwa zitseko ndi mazenera. Kwa mitundu yosiyanasiyana yaphokoso, kukonza magalasi osiyanasiyana ndiko kusankha kwaukadaulo komanso kopanda ndalama.
Mkulu pafupipafupi phokoso - insulating galasi
Galasi yotsekera ndi kuphatikiza magalasi awiri kapena kuposerapo. Mpweya wapakati pa dzenje wosanjikiza ukhoza kuyamwa mphamvu ya kugwedezeka kwa mawu apakati komanso apamwamba kwambiri, potero kumachepetsa mphamvu ya mafunde.Phokoso la kutchinjiriza kwa magalasi otsekera limalumikizana ndi makulidwe a galasi, mpweya wa dzenje lopanda kanthu komanso kuchuluka ndi makulidwe a spacer layer.
Nthawi zambiri, magalasi otsekera amakhala ndi zotsatira zabwino kwambiri zotsekereza pamaphokoso apakati komanso ma frequency apamwamba. Ndipo nthawi zonse makulidwe a galasi amachulukitsidwa, phokoso likhoza kuchepetsedwa ndi 4.5 ~ 6dB.
Choncho, kukula kwakukulu kwa galasi, kumapangitsa kuti phokoso likhale lolimba.
Titha kupititsa patsogolo mphamvu yotsekereza mawu a zitseko ndi mazenera powonjezera makulidwe a magalasi otsekera, kudzaza mpweya wa inert, ndikuwonjezera makulidwe a dzenje.
Phokoso lochepa kwambiri -kutsekerezagalasi laminated
Pansi pa makulidwe omwewo, galasi laminated limakhudza kwambiri kutsekereza mafunde apakati komanso otsika pafupipafupi, omwe ndi abwino kuposa magalasi oteteza.
Kanemayo pakati pa galasi laminated ndi wofanana ndi wosanjikiza damping, ndi PVB zomatira wosanjikiza ntchito kuyamwa sing'anga ndi otsika pafupipafupi mafunde phokoso ndi kupondereza magalasi kugwedera, kuti akwaniritse phokoso kutchinjiriza zotsatira.
Ndikoyenera kudziwa kuti kutulutsa mawu kwa interlayer kumatha kukhudzidwa ndi kutentha.
M'nyengo yozizira, interlayer idzataya mphamvu zake chifukwa cha kutentha kochepa komanso kuchepetsa kutsekemera kwa mawu. Galasi lopanda kanthu la laminated, lomwe limaphatikiza ubwino wa galasi lopanda kanthu ndi galasi laminated, likhoza kufotokozedwa ngati galasi "lozungulira" lopanda phokoso.
Kumanga Zosindikizidwa - Kutsekereza Magalimoto Amtundu Wamagalimoto
Kuphatikiza pa kudalira galasi, kutsekemera kwabwino kwa mawu kumakhudzananso kwambiri ndi mawonekedwe osindikizira.
MEDO imagwiritsa ntchito mitundu yosiyanasiyana ya zida zosindikizira za EPDM zamagalimoto monga zofewa komanso zolimba co-extrusion, thovu lathunthu, ndi zina zambiri, zomwe zimakhala ndi mphamvu zabwino kwambiri ndipo zimatha kuchepetsa kutulutsa mawu. Mapangidwe osindikizira amitundu yambiri, pamodzi ndi galasi, amathandizirana kuti apange chotchinga phokoso.
njira yotseguka
Ngakhale pali njira zosiyanasiyana zotsegulira zitseko ndi mazenera a dongosololi, deta yoyesera imasonyeza kuti njira yotsegulira yotsegulira casement ndi yabwino kusiyana ndi kutsetsereka kwa kukana kwa mphepo, kusindikiza ndi kutsekemera kwa mawu.
Pamaziko a zosowa zathunthu, ngati mukufuna kutsekereza mawu abwino, zitseko zamawindo ndi mawindo amakondedwa.
Komanso, amawindo okhotakhotandi mazenera awning akhoza kuonedwa ngati njira yapadera ntchito zitseko casement ndi mazenera, amene ubwino mawindo casement ndi ubwino wawo wapadera, monga mapendekedwe kutembenukira mazenera kukhala otetezeka ndi wodekha mu mpweya wabwino.
MEDO, yomwe imatenga katswiri wothetsera vutoli ngati udindo wake, yasonkhanitsa zaka pafupifupi 30 za luso lamakono, kudalira mwala wapangodya wamtengo wapatali wamtengo wapatali, umamasulira malo ogwiritsira ntchito ndi zosowa zamakasitomala m'chinenero chojambula, ndipo amagwiritsa ntchito akatswiri komanso okhwima. malingaliro asayansi kuti aime pa ogwiritsa ntchito abwino kwambiri, khalani ndi mwayi wopereka yankho labwino kwambiri la polojekiti iliyonse ndi kuganiza mwadongosolo komanso mapangidwe apamwamba.
