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.
