HONGKOU District has finished installing soundproof windows on over 300 households living near the city’s elevated Middle Ring Road that is expected to offer some relief to the residents troubled for a decade by ear-splitting noise from the traffic.

The cutting-edge windows has double glasses to muffle sound with air ventilation at the bottom, an official with the Liangcheng sub-district government said.

“We can finally sleep through the night after a decade of noise and disturbance,” said Ni Weiren, whose apartment is only 50 meters away from the elevated road.
