Serious sound pollution causes at least 30 different types of fatal diseases including heart attack, speakers cautioned at a press conference Sunday.
High-pitched sound coupled with polluted sound becomes the prime reason of insomnia, nausea, headache, irritation, inattention and ill temper, observed the speakers.
Presided over by MR Kabir, pro-vice chancellor of University of Asia Pacific (UAP) the press conference on 'Sound Pollution: Miserable public life and our duties' was organised by UAP and Work for Better Bangladesh (WBB) in the city.
Jubayer Bin Alam of Bangladesh University of Engineering and Technology, and Amit Ranjon Dey, programme manager of WBB also addressed the function.
According to Environment Protection Act 1997 the capital city were divided into five zones which were categorised as silent zone, residential area, mixed area, commercial area and industrial area.
The level of sound during daytime in the silent zone is 45 decibel and 35 decibel at night, it is 50 decibel during daytime and 40 at night in residential area, the same is 60 decibel at daytime and 50 decibel during night in mixed area, 70 decibel and 60 decibel respectively during day and night times at commercial areas, while in the industrial area it is 75 decibel during day and 70 decibel at night.
"But the level of sound ranges far more than the accepted range of 13 decibel to 40 decibel on an average, which is hindering the smooth evolvement of the present generation," said professor Jubayer.
He suggested for raising mass awareness and to stop using hydraulic horns in vehicles and urged the authorities to finalise the draft act on curbing sound pollution set forth in 2004.
