We all know how harmful hydraulic horns can be. Although it is banned in Dhaka city for its deafening noise, the whistle is widely used everywhere in the capital. The hydraulic horns used by buses, trucks and other motor vehicles in the crowded city streets are dangerous for human being. Such noise pollution is affecting the hearing power of people every day. According to the World Health Organisation (WHO), generally 60 decibel (dB) sound level can make a man deaf temporarily and 100 dB can cause complete deafness. The noise of any busy street in Dhaka has been estimated at 60 to 80 dB, with the sound of hydraulic horns measuring 95 dB. Recently, the High Court has directed six authorities concerned asking what steps have been taken to stop the use of hydraulic horns responsible for noise pollution.
We would like to acclaim the HC directives that aim to mitigate sound pollution caused by the use of the hydraulic horns. Dhaka city's sound pollution has reached a dangerous level. Experts say sound pollution created by the use of hydraulic horns can cause serious health problems, especially to children. We hope the law enforcement agencies will strictly enforce the HC directives and bring to book those who flout the order.
