Noise Pollution in Major Places in Dhaka and Proposing a Device to Keep Noise Log

This study attempts to build awareness to the noise pollution level of our city and also cultivate the areas of Dhaka city that are prone to health and environmental hazards in terms of noise pollution, by taking readings of certain locations in Dhaka city (Residential and commercial), and comparing it with the standard stated thresholds of DOE (Bangladesh department of environment). The purpose here is not only to analyze how good or bad the current noise level is but also to understand exactly why this situation should be taken seriously. We also found a pattern that suggested that noise pollution differed according to the time of the day. At the end a small proposal is placed, suggesting how we can use a miniature palm sized computer to record sound from places that are prone to health hazards. This will help keep a log of sound and help understand the situation of noise pollution we are having and may have in the future. It will also help in keeping sound files for analysis, and engage concerned people to keep a log of sound levels at a daily basis. Moreover, the analysis from the raw file can be used in traffic management system as well because most of the time, noise pollution occurs due to bad traffic management and due to vehicles not being maintaining. The major question is, do we have enough data collecting mechanisms to make such changes efficiently? We shall help resolve this matter.
