Sound levels everywhere in the capital are double the limit permitted under the Sound Pollution (Control) Rules 2006, revealed a recent survey by Poribesh Bachao Andolon (Poba).
The survey was conducted at 85 spots of different categories and recorded the daytime sound level in ‘silent areas’ at 75-97 decibel, while the sound levels in ‘residential areas’, ‘mixed areas’ and ‘commercial areas’ were recorded at 76-87 decibel, 73-102 decibel and 71-107 decibel respectively.
The recorded sound levels exceed the approved limits by 150-200 percent. According to the Rules, daytime/nighttime permissible sound levels in decibels are 50/40 (silent areas), 55/45 (residential areas), 60/50 (mixed areas), 70/60 (commercial areas) and 75/70 (industrial areas).
The findings of the survey were revealed at a press conference at Poba’s office at Kathalbagan in the city on Tuesday.
Though the areas falling within a 100-metre distance from hospitals, educational institutions are considered ‘silent areas’, where the permissible sound level is 50/40 decibels, the Poba survey team recorded 97 decibels in front of Dhaka Shishu Hospital during daytime.
