Q. Green Muffler is mainly used to reduce which type of pollution? (MPPSC State Services Prelims 2023)
Answer: Noise pollution
Notes: Green Muffler is a technique involving planting dense trees like Ashoka and Neem around populated or noisy areas to reduce noise pollution. It works by obstructing sound waves and filtering noise, particularly in places like roadsides and industrial zones. The scheme targets noise pollution reduction by creating green barriers that absorb and block sound. It is not primarily designed for soil, air, or water pollution control. The National Clean Air Programme addresses air pollution separately. Noise pollution is the specific focus of Green Muffler.
