Sir: Nowadays, it has become a fashion to have a bike in which a noisy silencer is fitted. Referentially, a silencer means a subject or a noun that suppresses sound that comes from the engines of vehicles, while here water falls back. Noisy sound created by these two wheelers is not observed by road users in common but when they enter colonies, little streets and the places where homes exist, its disgusting sound disturbs a lot. I collectively request to not only the Sindh government but also the federal government that if there is some law that can inhibit this act then please make our life free from noise and if there is no such law then please bring it about for the rest of the sufferers.
