Gujarat State Road Transport Corporation [Gsrtc] — Noise disturbances in buses

I often travel in GSRTC Buses.
Nowadays people watch videos on their mobiles with high volume which causes a great mental uneasiness.
When told to listen on their earphones or with low volumes, people often don't agree instead sometimes speak in abusive words.
Like Railways in Buses too it should be made mandatory to hear mobiles only with earphones.
