A recent global study has revealed some alarming findings about urban noise pollution, with one Indian city featuring prominently among the world's loudest urban centers. The research, published on November 28, 2025, highlights the growing concern of environmental noise affecting millions of city dwellers worldwide.
Global Noise Pollution Hotspots
The comprehensive study identified cities where noise levels have reached concerning heights, with Dhaka, Bangladesh topping the list at 119 decibels. Close behind, Moradabad in India claimed the second position with noise levels reaching 114 dB, making it the only Indian city to feature in this concerning top 10 ranking.
Other cities that completed the list of the world's noisiest urban areas include Islamabad, Pakistan (105 dB), Rajshahi, Bangladesh (103 dB), and Ho Chi Minh City, Vietnam (100-103 dB). The study also highlighted significant noise pollution in Ibadan, Nigeria (101 dB), Kupondole, Nepal (100 dB), Algiers, Algeria (99-100 dB), Bangkok, Thailand (99 dB), and New York City, United States (95 dB).
What These Noise Levels Mean
The reported decibel levels represent serious health concerns for residents. To put these numbers in perspective, continuous exposure to noise above 85 dB can cause permanent hearing damage. The levels recorded in these cities, particularly Moradabad's 114 dB, are comparable to the sound of a rock concert or a chainsaw operating nearby.
Medical experts warn that prolonged exposure to such high noise levels can lead to various health issues beyond hearing loss, including sleep disturbances, cardiovascular problems, increased stress levels, and reduced cognitive performance in children.
The Indian Context and Way Forward
Moradabad's inclusion in this global list highlights the urgent need for noise pollution control measures in Indian cities. Known as the brass capital of India, the city's industrial activities combined with growing urban traffic contribute significantly to its noise levels.
Environmental activists are calling for stricter enforcement of noise pollution norms and greater public awareness about the health impacts of excessive noise. The findings serve as a wake-up call for urban planners and policymakers to incorporate noise reduction strategies in city development plans.
As cities continue to grow and industrialize, managing noise pollution becomes increasingly crucial for public health and quality of life. The study underscores the global nature of this environmental challenge that requires coordinated efforts at local, national, and international levels.
