Guwahati, April 26: The city today observed No Horn Day, initiated by the National Initiative of Safe Sound (NISS), to mark the International Noise Awareness Day.

As part of the day's programme, NISS distributed posters among schoolchildren, police and commuters against unnecessary honking on the roads. Posters were also put up at prominent places, including educational institutions.

"We have distributed about 100 posters to spread awareness among people. In today's drive, we covered 35 schools, six colleges and 15 police stations of Guwahati where posters and leaflets were distributed," said NISS state coordinator Swagata Khanna.

The drive was carried out by NISS in association with Indian Medical Association and the Association of Otolaryngolists of India.

"Noise pollution affects old people, children and pregnant women," said S.B. Phookan, secretary of the Northeast branch of the Association of Otolaryngolists of India.

Kamrup (metro) deputy commissioner M. Angamuthu yesterday directed the district transport officer (enforcement) to take steps to remove all air, horns, horns and other high decibel horns from vehicles plying in Guwahati.

Angamuthu also directed the Pollution Control Board of Assam (PCBA) to collect, compile and publish all technical and statistical data relating to noise pollution.

He requested the commissioner of Guwahati Municipal Corporation to impose restrictions while issuing no-objection certificates for construction of buildings and direct the builders and the promoters not to use or operate sound emitting construction equipment at night.

The district administration has also planned to create silent zones in the city.
