Once beautiful Dhaka is facing lots of challenges and myriad problems. Noise pollution, beyond any doubt, is a matter of great concern as it has already exceeded the tolerable limits.
The city has become a place of extreme sound. Jarring sounds from the construction areas, political gatherings, miking and hucksters voices are very peculiar in outdoor sites of Dhaka. Disgusting sound from dragging furniture to and fro, people clearing their throat, gagging, loudly spitting, mostly common in abode and workplaces, are also giving a dimension to sound pollution. Reckless whistling of prohibited hydraulic horn in most motorized vehicle is now in extreme condition. It is an irony that violating the rule, state patronized BRTC vehicles are also indiscriminately using banned hydraulic horns.
Now the noise level of any busy street in Dhaka, with the sound of vehicles, is estimated at 95 decibel (dB). According to WHO, generally 60dB sound can make a man deaf temporarily and 100dB of it can cause complete deafness.
It is high time for the individuals and authorities concerned, the media, the NGOs and the government to work together to reduce noise level for the sake of city dwellers.
