According to a survey published by the United Nations Environment Program (UNEP) last month, Dhaka, Bangladesh’s capital, is the world’s noisiest metropolis. Dhaka is consistently ranked as one of the most polluted cities in the world. The World Health Organization (WHO) has set a noise intensity limit of 55 decibels for a certain region. Dhaka, on the other hand, was determined to be twice as loud, at 110 to 132 decibels. As many as 66 percent of traffic cops work on the road to control traffic, and this high noise intensity noise is causing them hearing and sleeping problems on a daily basis. Furthermore, loud noises can increase blood pressure and pulse rates, produce mental stress, and interfere with amusement and personal interactions. Keeping all of this in mind, we designed a real-time noise pollution monitoring system that will assist in conducting experiments in this type of environment by evaluating noise intensity and automatically sending data to a IoT cloud-based platform.
