Health Desk—Oct 07, 2017: Noise pollution has turned acute in Dhaka as it always goes far beyond the permissible level, putting the public health at risk, says a new survey of the Department of Environment (DoE).

The survey, conducted at 70 points of the city this year, reveals that sound pollution has reached the highest 120-130 decibels (dB) at many points -- almost double the permissible level.

According to the Noise Pollution (Control) Rules 2006, the acceptable sound condition for Bangladesh is 50dB for daytime and 40dB for the night in silent areas, 50dB for daytime and 45dB for the night in residential areas, 60dB for the daytime and 50dB for night in mixed areas (residential, commercial and industrial localities), 70dB for daytime and 60dB for the night in commercial areas, and 75dB for daytime and 70dB for the night in industrial areas.

The survey shows that noise pollution has increased alarmingly at different parts of the capital. The highest noise level recorded at Farmgate was 130.2dB during daytime and the lowest 65.7dB at night.

The noise level was above 120dB during daytime at Gabtoli, Arambagh intersection, Gulshan-2 intersection, Gulistan intersection, Mirpur 10 intersection, Banglamotor, New Market, Mascot Plaza of Uttara, Jagannath University, among other areas.

Among the 70 points, the lowest sound level was recorded 99.6dB during daytime and 43.7dB at night at Road-18 of Uttara-14.

According to the World Health Organization (WHO), generally 60dB sound can make a man deaf temporarily and 100dB sound can cause complete deafness.
