IIT Madras is developing a technology aimed at reducing noise pollution in Chennai, targeting urban hotspots with a potential reduction of 30-40 decibels. The system leverages acoustic resonators and barrier mechanisms to absorb and deflect sound waves, using locally sourced materials such as PVC and vegetative buffers. Professor S M Shiva Nagendra from the Civil Engineering department emphasized that achieving this reduction could significantly calm high-noise environments. The project is set to be implemented at critical locations like the Cancer Institute junction, identified as a sensitive zone. This initiative follows a comprehensive noise mapping study conducted by IIT Madras, which revealed that road traffic is the leading cause of urban noise, with areas like Valasaravakkam frequently exceeding the Central Pollution Control Board (CPCB) noise limits of 65 decibels during the day. The study also noted that natural elements and engineered structures could effectively mitigate noise when designed appropriately.
