A bench headed by NGT chairperson Justice Swatanter Kumar asked the city government to examine the sound levels in the area and take steps like fixation of barriers to curb the noise pollution.
"The said mapping shall be done when demonstrations are going on and when the demonstrations are not being held in that area. They shall also identify alternative sites to the present one for holding of demonstrations to prevent noise pollution and traffic congestion, resulting in air pollution," the bench said.
The green panel said the Supreme Court and the High Courts have passed orders from time to time for relocation of the venue to some other place but nothing has been done.
The plea had said regular protests "violate their right to live in a peaceful and healthy environment, right to silence, right to sleep and right to life with dignity."
They had also claimed that despite the law being in place disallowing noise to cross 40 decibels, they have to bear the sound from loudspeakers which sometimes go up to as high as 300 decibels.
