Zvichida kutinhira kwechitima chekare chinomhanya mubhaisikopo kunogona kumutsa ndangariro dzedu dzehuduku zviri nyore, sokunge kutaura nyaya yenguva yakapfuura.
Asi kana rudzi urwu rweruzha rwusipo mumabhaisikopo, asi runowanzoonekwa pamba pedu, pamwe iyi "yeuko yehucheche" inoshanduka kuita matambudziko asingaperi nekukasira. Ruzha rusingafadzi urwu ruzha.
Ruzha harungovhiringidzi zviroto zvevanhu chete, asi zvinonyanya kukosha, nzvimbo yeruzha yenguva refu inogona kukonzera kukuvadzwa kusingachinjiki kune physiology uye psychology yevanhu, uye ndeimwe yemanyuko akakosha ekusvibisa munharaunda yemazuva ano.
Kuderedza ruzha uye kuvharidzira ruzha kwave kudiwa kwakaoma nekukurumidza kwevanhu.
Kazhinji kutaura, izvo zvinokanganisa mwero weruzha zvinonyanya zvinosanganisira huwandu hweinonzwika sosi uye chinhambwe pakati peiyo odhiyo frequency uye sosi yekurira.
Muchiitiko chekuti vhoriyamu, odhiyo frequency uye chinhambwe pakati peinzwi sosi uye munhu haashandurwe nyore, nekusimbisa yemuviri inovharira mutsindo - ruzha rwekuvharidzira kuita kwemagonhi nemahwindo, kufambisa kwenzwi kunovharwa zvakanyanya sezvinobvira, nekudaro. kugadzira inonakidza uye yakasununguka zvakatipoteredza.
Ruzha haruna kugadzikana mumuviri kana mupfungwa, harufadzi, harusununguke, harudiwi, kana kuti runogumbura, rwusingagamuchirwe kune vanorunzwa, runokanganisa nhaurirano dzevanhu kana kufunga, basa, kudzidza, uye kuzorora ruzha rwe.
Nzeve yemunhu yekunzwa frequency renji yeruzha ingangoita 20Hz ~ 20kHz, uye huwandu huri pakati pe2kHz ne5kHz ndiyo inzvimbo inonzwa zvakanyanya yenzeve yemunhu. Kunyanya kuderera uye kukwira kweruzha rwemhepo kunogona kukonzera kusagadzikana.
Iyo yakanyanya kugadzikana vhoriyamu huwandu ndeye 0-40dB. Naizvozvo, kudzora nzvimbo yedu yekugara uye yekushanda acoustic munzvimbo ino inogona kuvandudza kunyaradza zvakanyanya zvakananga uye nehupfumi.
Low-frequency noise inoreva ruzha rune frequency ye20 ~ 500Hz, frequency ye500Hz ~ 2kHz i frequency yepakati, uye yakakwirira frequency ndeye 2kHz ~ 20kHz.
Muhupenyu hwezuva nezuva, air-conditioning compressors, zvitima, ndege, injini dzemotokari (kunyanya pedyo nemigwagwa uye viaducts), zvikepe, elevator, michina yekuwachisa, mafiriji, nezvimwewo zvinonyanya kuderera-ruzha, apo nyanga uye motokari inoridza muridzo. , zviridzwa, kutamba kwemativi mana, kuhukura kwembwa, kutepfenyura kuchikoro, hurukuro, zvichingodaro.
Low-frequency ruzha rune kureba kwekutapurirana chinhambwe, simba rekupinza rakasimba, uye harichinji zvakanyanya nedaro, rinova rinonyanya kukuvadza muviri wemunhu.
Ruzha rwepamusoro-soro haruna kupinza, uye ruchadzikiswa zvakanyanya sezvo chinhambwe chekuparadzira chinowedzera kana kusangana nezvipingamupinyi (somuenzaniso, pakuwedzera kwemamita gumi padanho rekupararira reruzha rwepamusoro-soro, ruzha ruchadzikiswa ne6dB).
Vhoriyamu ndiyo yakanyanya intuitive kunzwa. Vhoriyamu inoyerwa mumadecibel (dB), uye ambient vhoriyamu iri pasi pe40dB ndiyo yakanyanya kugadzikana nharaunda.
Uye huwandu hweanopfuura 60dB, vanhu vanogona kunzwa kusagadzikana kuri pachena.
Kana vhoriyamu ichipfuura 120dB, zvinongotora miniti imwe chete kukonzera kusanzwa kwenguva pfupi munzeve yemunhu.
Pamusoro pazvo, daro riri pakati pechitubu chenzwi nemunhu wacho rinokanganisawo maonero anoita munhu ruzha. Kuwedzera chinhambwe, kuderera kwevhoriyamu.
Nekudaro, kune yakaderera-frequency ruzha, mhedzisiro yedaro pakuderedza ruzha haisi pachena.
Kana zvisingabviri kuita shanduko dzakawandisa kune nharaunda ine chinangwa, ingave sarudzo yekuchenjera kuchinja kune yemhando yepamusoro gonhi nehwindo, uye uzvipe iwe imba ine rugare uye yakanaka.
Seti yakanaka yemagonhi nemahwindo inogona kuderedza ruzha rwekunze nekupfuura 30dB. Kuburikidza nehunyanzvi musanganiswa kumisikidzwa, ruzha runogona kuderedzwa zvakare.
Girazi ndiyo inonyanya kukosha chikamu chinokanganisa kuvharwa kwemagonhi nemahwindo. Kune mhando dzakasiyana dzeruzha, kugadzirisa girazi rakasiyana ndiyo yakanyanya hunyanzvi uye ine hupfumi sarudzo.
High frequency ruzha - insulating girazi
Insulating girazi isanganiswa ye2 kana kupfuura zvidimbu zvegirazi. Iyo gasi iri pakati nepakati hollow layer inogona kutora simba repakati uye yakakwirira frequency ruzha vibration, nekudaro ichidzikisa kusimba kwemafungu.Inzwi rekudzivirira mhedzisiro yegirazi inodzivirira ine hukama nehupamhi hwegirazi, gasi regomba layer uye nhamba uye ukobvu hwe spacer layer.
Muzviitiko zvakawanda, insulating girazi ine yakanaka kwazvo yekuvharira mhedzisiro pane yakakura yepakati uye yakakwirira frequency ruzha. Uye nguva dzese ukobvu hwegirazi hwakapetwa kaviri, ruzha runogona kudzikiswa ne4.5 ~ 6dB.
Naizvozvo, iyo yakakura kukora kwegirazi, kusimba kwekudzivirira inzwi.
Isu tinokwanisa kuvandudza ruzha rwekuvharidzira mhedzisiro yemagonhi nemahwindo nekuwedzera ukobvu hwegirazi inodzivirira, kuzadza inert gasi, uye kuwedzera ukobvu hwegomba layer.
Low frequency noise -insulatinggirazi laminated
Pasi pehupamhi hwakafanana, girazi rakagadziriswa rine mhedzisiro yakakosha pakuvhara epakati uye yakaderera frequency mafungu enzwi, zviri nani pane insulating girazi.
Iyo firimu iri pakati pegirazi ine laminated yakaenzana nekunyorovesa layer, uye PVB adhesive layer inoshandiswa kutora epakati uye yakaderera frequency ruzha masaisai uye kudzvanyirira girazi kuzunguzika, kuitira kuti iwane iyo yekuvharisa mutsindo.
Izvo zvakakosha kucherechedza kuti ruzha rwekuvharidzira kuita kweiyo interlayer inogona kukanganiswa nekupisa.
Munguva yechando inotonhora, iyo interlayer icharasikirwa nehumwe hunyoro hwayo nekuda kwekushisa kwakadzika uye kuderedza ruzha rwekudzivirira. Girazi regirazi rakakomberedzwa, iro rinosanganisa zvakanakira ese ari maviri girazi uye laminate girazi, rinogona kutsanangurwa se "se-kutenderera" girazi risinganzwi.
Yakavharwa Kuvaka - Yemotokari Giredhi Soundproofing
Pamusoro pekutsamira pagirazi, kunaka kwekuvharisa inzwi kunoenderanawo zvakanyanya nechisimbiso chimiro.
MEDO inoshandisa marudzi akasiyana-siyana eEPDM motokari-giredhi yekuisa chisimbiso zvinhu zvakadai sezvinyoro uye zvakaoma co-extrusion, foam yakazara, nezvimwewo, izvo zvine hutano hwakanaka uye zvinogona kuderedza zvinobudirira kuiswa kwezwi. Iyo yakawanda-channel yekuisa chisimbiso dhizaini dhizaini, pamwe negirazi, inopindirana kuti ivake chinovharira ruzha.

Kunyangwe paine nzira dzakasiyana dzekuvhura dzemagonhi nemahwindo eiyo sisitimu, iyo data yekuyedza inoratidza kuti nzira yekuvhura yekuvhura kesement iri nani pane kutsvedza maererano nekupokana kwemhepo, kuvhara uye kuvharisa inzwi.
Pahwaro hwezvido zvakazara, kana iwe uchida zvirinani kuvharwa kwenzwi, magonhi emagonhi nemahwindo anosarudzwa.
Mukuwedzera, thetilt turn windowsuye mahwindo evhavha anogona kutariswa seyakakosha nzira dzekushandisa dzemagonhi emagonhi nemahwindo, ayo ane zvakanakira mahwindo ejasi uye ane mabhenefiti avo akakosha, senge mahwindo ekutenderera achive akachengeteka uye akapfava mumhepo.
MEDO, iyo inotora iyo system solution nyanzvi semutoro wayo, yakaunganidza angangoita makore makumi matatu ekuunganidza tekinoroji, ichivimba neyakapfuma uye yakazara system chigadzirwa matrix pakona, inoshandura nharaunda yekushandisa uye zvinodiwa nevatengi mumutauro wekugadzira, uye inoshandisa nyanzvi uye yakasimba. mafungire esainzi kuti amire pane akanakisa evashandisi, sangana nemaonero ekupa iyo yakakwana mhinduro kune yega yega purojekiti ine yakarongeka yekufunga uye yekucheka-kumucheto dhizaini.
