What approach can help mitigate the negative impact of sound pollution in urban areas?

Expanding green spaces is an effective approach to mitigating the negative impacts of sound pollution in urban areas. Green spaces, such as parks, gardens, and natural areas, create a buffer that can absorb, deflect, or refract sound waves, leading to a reduction in overall noise levels. The presence of vegetation can also enhance the aesthetic value of an area and improve air quality, contributing to a healthier urban environment.

Additionally, green spaces provide a natural habitat for wildlife and recreational opportunities for residents, promoting mental well-being. These areas often encourage quieter activities such as walking, reading, or picnicking, which can further promote a peaceful atmosphere in the community.

In contrast, increasing the number of vehicles or adding more residential units typically leads to higher levels of noise, exacerbating sound pollution. Building more industrial zones would likely contribute to increased noise generation as well, given that industrial activities often involve heavy machinery and equipment that produce significant sound. Thus, expanding green spaces stands out as a constructive and holistic strategy to combat sound pollution effectively.
