Research question: What effect does vegetation have on sound pollution in Delhi?

Noise pollution is a major issue, particularly in urban areas, and traffic noise is the most significant source of noise in cities. Because of the large number of cars and other road vehicles with internal combustion engines, traffic noise is a substantial source of noise pollution. When commuters honk even when the traffic light is red, the unwanted sound decibels rise in the periphery of the junction. This noise may affect a person, such as hearing impairment, high blood pressure, stress, etc. At traffic signals, people blow their horns restlessly, adding environmental noise. This paper looks at how the presence of a green belt helps prevent sound from traffic from affecting buildings near traffic signals.
