Tengani chitsanzo cha kumanga misewu yayikulu.Misewu ikuluikulu idzachititsa kuti phokoso la magalimoto liwonongeke m'madera okhala, masukulu, ndi zipatala zomwe zili m'mphepete mwa mzerewu.M'malo oterowo, timagwiritsa ntchito mawu oyenerera oti acoustics, omwe timawatcha kuti malo omvera omvera.
Kodi phokoso la pamsewu lidzafunika pamikhalidwe yotani kuti akhazikitse zotchinga mawu?Masiku ano, opanga zotchinga zomveka adzawafotokozera mwatsatanetsatane.Ndi chitukuko cha magalimoto, misewu yowonjezereka ikukonzedwa, ndipo magalimoto a ntchito zosiyanasiyana ali pamsewu, zomwe zikuchititsa kuti phokoso la magalimoto liwonongeke kwa anthu okhala m'njira.Kenako, tiyeni tikambirane pamodzi, kodi phokoso la pamsewu lidzafunika motani kuti akhazikitse zotchinga mawu?

Malinga ndi malamulo a "Environmental Protection Law of the People's Republic of China" ndi "Environmental Noise Pollution Prevention Law of the People's Republic of China", pofuna kuwonetsetsa kuti malo omvera m'madera omwe ali m'mphepete mwa mzerewo akukwaniritsa zofunikira zomwe zili mu dziko muyezo GB3096-93, kuchotsa kapena kuchepetsa galimoto magalimoto tcheru mfundo m'mbali mwa mzere Miyezo ayenera kumwedwa kupewa ngozi phokoso kuchepetsa phokoso ku osiyanasiyana wololera.
Mu "Environmental Noise Standard for Urban Areas" yomwe idakhazikitsidwa mu 1993, madera akumatauni agawidwa m'magulu asanu, ndipo zofunikira za phokoso pagulu lililonse ndi:
Kalasi : Malo: Malo osamalira thanzi abata, malo a villa, malo a hotelo ndi madera ena kumene bata ndi kofunika kwambiri, 50dB masana ndi 40dB usiku;madera amtunduwu omwe ali m'midzi ndi kumidzi amatsatira mosamalitsa muyezo wa 5dB.
Malo amtundu wachiwiri: Madera omwe amakhala ndi malo okhala, chikhalidwe ndi maphunziro.55dB masana ndi 45dB usiku.Malo okhala kumidzi angatanthauze kukhazikitsidwa kwa miyezo yotereyi.
Malo amtundu wachitatu: malo osakanikirana, malonda, ndi mafakitale.60dB masana ndi 50dB usiku.
Mtundu wachinayi wa dera: zone mafakitale.65dB masana ndi 55dB usiku.
Malo amtundu wachisanu: madera omwe ali mbali zonse za misewu yayikulu yamsewu yamzindawu, madera omwe ali mbali zonse za msewu wamadzi wodutsa m'tawuni.Malire a phokoso amagwiranso ntchito pamiyezo yotereyi ya madera a mbali zonse za njanji zazikulu ndi zachiwiri zodutsa m’tauni.70dB masana ndi 55dB usiku.
Kumanga zotchinga za mawu kumbali zonse ziwiri za msewu waukulu ndi njira yabwino yopewera ndi kuletsa kuipitsidwa kwa phokoso la pamsewu.Zolepheretsa phokoso zimakhala ndi kutalika ndi kutalika kokwanira.Nthawi zambiri, phokoso limatha kuchepetsedwa ndi 10-15dB.Ngati mukufuna kuwonjezera kuchuluka kwa kuchepetsa phokoso, muyenera kukonza zotchinga zomveka komanso kapangidwe kake.
