Hydraulic horn

Me and shafeen in front of a plain, he had to do same thing on road when any vehicles make too loud sound.

As far as I know, this kind of horn is banned in our country (Bangladesh). But in Dhaka city I have faces this problem. Labbayek bus has this loud sound horn and if you are beside the bus then you must faced problem. Again some oil tankers have this kind of sound too. My son feels difficulty with this loud sound, especially when we sit on the rickshaw and this horn sounds beside us. He gave his toy to me and keep cover his ear with his little hands. I hope these vehicles will change their horns.
