Due to rapid urbanization and exponential growth in transportation, traffic noise has become a major concern as it not only disrupts daily life but also has severe adverse health effects on humans and can even lead to mortality. This paper focuses on analyzing the noise levels in Lucknow city over a decade and establishes its correlation with the impact on human health in terms of annoyance and sleep disturbance. The study reveals that the noise levels exceed prescribed standards in most locations during both day and night time, with Charbagh being the worst affected by noise pollution. The increase in noise levels over time has resulted in a higher percentage of residents experiencing sleep disturbance and annoyance.
Due to rapid urbanization and exponential growth in transportation; traffic noise has become a major area of concern. Noise not only disturbs our day-to-day life but also have severe adverse health effects over humans which further may lead to mortality. This paper focuses on the behavior of noise levels of Lucknow city over a decade and establishes its correlation with impact on human health in terms of annoyance and sleep disturbance. Apart from L-eq, different noise parameters like L-10, L-50, L-90, Traffic Noise Index (TNI), Noise Pollution Index (NPI), and Noise Climate (NC) have also been analyzed to understand the variation of noise. At all the locations, the noise level has been found exceeding their prescribed standards during day time and night time except at Amausi. Out of nine locations, TNI was found to be exceeding at three locations during day time and NPI exceeding at one location. However, during night time both values of TNI and NPL were observed within the limit at all the locations. From the noise map of the city during day time and night time, among all sampling locations, Charbagh has been found to be worst affected by noise pollution. A strong positive correlation has been observed among the total population, vehicular count, and day and night time noise data, which directly contribute to a higher percentage of sleep disturbance and annoyance among residents. Due to the increase in noise levels over a period of time, almost four times the population get affected by high annoyance and almost double the population get affected by sleep disturbance.
