Assessment of noise pollution in Dhaka city
Like many other mega cities of developing countries, noise pollution in Dhaka city of Bangladeshis a big concern. Here noise is produced from different sources like traffic, loudspeaker,people gathering etc. To mitigate the noise pollution in Dhaka city, the governmentof Bangladesh has recently passed a new ordinance and has modified the existing traffic controlrules. However, the condition did not improve as much as expected. Exposure to highlevel noise may cause severe stress on the auditory and nervous system of the city dwellers,particularly the children. The extreme effects e.g. deafness and mental breakdown are alsooccasionally reported. This paper reports the level of noise pollution in Dhaka city. For thispurpose noise levels have been measured at ten major locations of the city from 8 AM to 10PM during the working days. The data have been analyzed to calculate various noise parameterssuch as Leq, and Lnp. It is observed that at all the locations, the level of noise remains farabove the acceptable limit for all the time. Comparison of present results with the existingprevious results shows that noise level in the Dhaka city is increasing day by day. The papersuggests that urgent measures should be taken into consideration to control the level of noisepollution in the city and vulnerable institutions like kinder gardens, schools and hospitalsshould be located far away from the road side. ; QC 20120424
