Bengaluru Metro Rail Corporation [bmrcl] — Loud Conversations

People these days are insensitive to the DB (decibel) levels of conversations in most of the lines. They actually bring huge inconvenience to co-passengers and especially elders and sick people. We need a way to monitor and control these rude and indecent style of travelling. I have many times told the security near stations about this, but I know they can't do much about it. For some days repeated announcement and some sort of marshals to control this behavior might help to reduce the noise within various cars of the metro. It should always be a pleasant journey in the midst of heavy rush. Hope you would look at it !
