Sound Pollution: Short Note। Job & Admission Preparation

Sound pollution, often overlooked, is a critical environmental issue that has far-reaching consequences on both human health and the surrounding ecosystem. It is one of the major concerns in densely populated areas where urban development is on the rise. The importance of understanding sound pollution, its sources, effects, and possible solutions cannot be overstated, especially for those preparing for competitive job and admission exams. This short note provides essential insights into sound pollution, helping students, exam candidates, and anyone interested in environmental studies to grasp the importance of tackling this issue for a healthier and quieter world.
Short Note: Sound Pollution
Noise pollution refers to unwanted or excessive sound that can have harmful effects on human health, wildlife, and environmental quality. This type of pollution is commonly generated within various industrial facilities and workplaces, but it also arises from sources such as highway, railway, and airplane traffic, as well as outdoor construction activities.
According to a report by the United Nations Environment Programme (UNEP), the average noise frequency in Dhaka currently stands at 119 decibels, more than twice the tolerable standard. Noise pollution is more than just a disturbance—it has serious health implications. Apart from causing hearing loss, prolonged exposure to excessive noise can lead to increased blood pressure, higher pulse rates, irritability, anxiety, mental fatigue, and disruptions in sleep, recreation, and personal communication.
Noise pollution control, therefore, is crucial in both the workplace and within communities. To mitigate noise pollution, many places have implemented measures such as restricting honking in specific areas, introducing soundproof systems, and limiting the use of loudspeakers.
A significant step in addressing noise pollution was taken on September 29, 2024, when the ‘Silent Zone’ initiative was launched near Dhaka’s Hazrat Shahjalal International Airport. This three-kilometer area around the airport was declared a ‘Silent Zone’ to make it a horn-free zone, significantly reducing noise pollution in this busy area.
Conclusion
Understanding and addressing sound pollution is essential for the well-being of both individuals and society. As we strive for healthier living environments, controlling noise pollution becomes an urgent priority. The information provided here is valuable not only for environmental studies but also for competitive exams where knowledge of current environmental issues is critical. I encourage everyone to stay aware and informed about the impacts of noise pollution and to actively support measures that contribute to a quieter, more peaceful world.
