The Department of Environment (DoE) has introduced strict measures to curb noise pollution, banning the use of vehicle horns in residential areas from 9:00pm to 6:00am under the newly issued Noise Pollution (Control) Rules, 2025.
In a public notice signed by Director General Dr Md Lutfur Rahman, citizens have been urged to comply with prescribed sound limits and regulations aimed at improving urban livability.
The rules set maximum permissible noise levels by zone—40 decibels in silent areas such as hospitals and schools, and up to 75 decibels in industrial zones. Exceeding these limits is strictly prohibited.
The use of high-sound equipment in public places without prior approval has also been banned. Even with permission, sound levels must not exceed 90 decibels and usage is limited to a maximum of five hours. No such equipment will be allowed after 11:00pm.
The notice further prohibits the manufacture, import, sale, storage, and use of horns that exceed approved sound levels. Honking is completely banned in silent zones, including areas around hospitals and educational institutions. Firecrackers, fireworks, or any other sources of loud noise are also prohibited in these areas.
To ensure quieter neighbourhoods, horn use has been restricted in residential areas during nighttime hours. Additionally, activities that generate loud noise have been banned in natural forests and wildlife habitats to protect biodiversity.
Restrictions have also been imposed on picnics and the use of loud equipment in forest areas. Construction activities near residential zones have been regulated as well—no machinery can be operated within 500 metres of residential boundaries between 7:00pm and 7:00am.
The DoE warned that violations of these rules will lead to immediate action. Traffic sergeants and authorised officials can take enforcement measures on the spot if noise pollution is detected.
The department has called on the public to remain aware of the harmful effects of noise pollution and to follow the new regulations for a healthier environment.
