Sound level in most areas of Dhaka city is significantly higher than the standard level, said a research conducted by the Centre for Atmospheric Pollution Study (CAPS) of the Stamford University Bangladesh.
The findings of the research have been published in a press conference on Friday at the Dhaka Reporters Unity (DRU) organised by Bangladesh Paribesh Andolon (BAPA) and Stamford University.
Prof Dr Ahmed Kamruzzaman Mazumdar, founder-director of CAPS attended as key speaker at the conference.
"Our research team conducted a sound pollution survey in 70 areas of Dhaka city. We found that the sound level was higher than the standard level in silent, residential and mixed zones 100 percent of the time," he said.
"The sound level was higher than the standard level during 97.58 percent of the time in commercial zones and 71.75 percent of the time in industrial zones.''
Prof Mazumdar said they surveyed 12 spots in the secretariat area with an automatic sound level meter from December 14-22 last year.
The standard sound level is 50 decibels during daytime in the area. But the actual sound level at those spots was higher than the standard level throughout daytime.
The sound level was higher than 70 decibels at 11 spots throughout the day.
Among others, Prof Muhammad Ali Naki, vice-chancellor of Stamford University, Kazi Sarwar Imtiaz Hashmi, former additional directorate general of the Department of Environment, and Dr Abdul Matin, executive president of BAPA, were also present at the event.
