New Delhi: Despite a comprehensive standard operating procedure being in place to curb noise pollution in the capital, key regulations governing loudspeakers and public address systems remain largely unenforced.The issue has resurfaced following violations by kanwar yatra processions featuring high-decibel DJ setups, highlighting a persistent gap between policy on paper and ground reality.Police officers said they have no specific data on challans issued for violations during the processions.The guidelines require district cops to coordinate with civic authorities and power distribution companies to ensure police clearance is obtained before tents are pitched, loudspeakers supplied or electricity connections provided for public and private functions. RWAs and market associations are also to be sensitised about noise pollution and legal action that can be taken in case of violations.The provisions were further tightened through an amended order. While the rules focused on noise levels at the periphery of public places, with sound from loudspeakers, public address systems and other sources not permitted to exceed the prescribed ambient noise level by more than 10 dBA, the amended order added a separate limit for privately owned sound systems and sound-producing instruments. it stated that the noise level at the boundary of the private premises should not exceed the ambient noise standard by more than 5 dBA.The rules also restrict the use of loudspeakers and public address systems between 10pm and 6am, except in specified circumstances. State govts can permit their use from 10 pm to midnight during cultural or religious festive occasions for a limited period, not exceeding 15 days in a calendar year.The ground reality, however, seems quite different, with several Delhi residents complaining of the use of boom boxes late into the night in the kanwar season.In another measure aimed at controlling excessive noise, Delhi govt notified mandatory installation of sound limiters in audio and public address systems following directions of National Green Tribunal (NGT) in 2019. The notification makes it mandatory for audio or PA systems used at govt and private functions to be fitted with sound limiters. Again, the rules seem to remain on paper.The norms prohibit manufacturers, dealers, shopkeepers, agencies renting out PA systems and individuals from selling, purchasing, supplying, renting out or using the systems without sound limiters.However, enforcement remains a challenge, with loudspeakers and other high-volume sound systems continuing to be used at public and private functions across Delhi in violation of prescribed norms.
