The Government says that a cracker should not emit more than 90 dB at a distance of 5 metres. Then how about the HOOOOOOOOOOOOONK!!!! that cars and bikes emit? Forget busy intersections, even the so-called silent zones - schools and hospitals - are not spared from the earsplitting cacophonous horn. And not to forget that annoying reverse-parking alarm. Can you SILENCE THEM?
