Which technique is used to minimize noise pollution from landfills?

The technique of installing noise barriers or maintaining distance from residential areas effectively minimizes noise pollution from landfills. Noise barriers are structures designed to absorb or deflect sound waves, thereby reducing the volume of noise that reaches nearby communities. By strategically locating landfills away from populated areas, the potential for noise disturbances is diminished.

This method addresses one of the primary concerns associated with landfills, as the operation of heavy machinery, waste processing, and transportation vehicles can generate significant noise. By combining physical barriers and strategic placement, the impact of noise on surrounding neighborhoods can be significantly reduced, leading to a more peaceful living environment for residents close to landfill sites.

The other choices, while they may contribute to reducing certain impacts associated with landfills, do not specifically target the minimization of noise pollution as effectively as installing barriers or maintaining a distance from residential areas.
