The Department of Environment (DoE) yesterday fined Square Hospital Ltd Tk 5 lakh for creating sound pollution at Panthapath in the city.
In a drive, a team led by DoE Director (Enforcement) Mohammed Munir Chowdhury found a high-voltage generator producing noise at 65-75 decibels at the hospital around 10:50pm.
The environment preservation law declares 100 square metres of space around a hospital as silent zone and limits noise level below 35 decibels in those areas at night.
The Square Hospital authorities were warned twice on October 12 and October 18 last year over the allegation.
Md Yusuf Ali Pradhan, general manager of the hospital, at a hearing yesterday admitted the allegation and promised to stop the generator from the very day.
