Introduction

Noise pollution poses significant environmental and health challenges, necessitating effective control methods to mitigate its impact. Various noise control techniques include the use of sound barriers, acoustic insulation, and advanced technologies such as active noise cancellation. Vegetation plays a vital role in noise control by acting as a natural sound buffer; trees and shrubs can absorb and deflect sound waves, thereby reducing noise levels.

Environmental problems associated with noise pollution include disturbance to wildlife, degradation of ecosystems, and adverse effects on human health such as hearing loss, stress, and sleep disturbances.

Addressing these issues requires a comprehensive approach involving noise control measures, strategic urban planning, and the preservation and enhancement of green spaces.
