Noise pollution

I am a morning walker. Every morning at 5.00 AM I go to a nearby district park for my morning walk. For last few days, I find the above DG set running with its enclosure open from three sides. As per the board seen in the photo, deep sewer work is going on a contract given by the government. It creates loud noise and disturbs the peaceful harmony of the morning.

As per Noise Pollution law, DG sets are to be housed in an acoustic enclosure.But here the enclosure is kept open by three sides to create noise pollution.
