As traffic noise pollution intensifies due to the rising number of vehicles, there is an increasing need for effective noise reduction strategies. Traditional methods, such as installing sound barriers, creating buffer zones, and using soundproof materials on buildings, have been extensively studied. This study focused on evaluating the effectiveness of plants as sound barriers for traffic noise reduction. The research was conducted on a road segment near a residential area in Zhengzhou City, chosen for its suitability for the study. Measurements were taken 30 to 40 meters from the traffic noise source. Results indicated that dense plantings could achieve a modest noise reduction, ranging from 3 to 10dB(A). However, factors such as the distance of noise transmission and the volume of traffic were significant considerations. Consequently, the study concluded that while plants can contribute to noise reduction, their overall effect is limited.
