Illuminate about Chrome’s Hidden Tab Mute Feature

Hello, I am using windows XP operating system and I want to know briefly about Chrome’s Hidden Tab Mute. Is Hidden Tab Mute Feature finest in XP operating system? Can I set this up in all browser versions of chrome? What is mean by mute tab? What does it actually? Can this also be available in smart phone and tablet? Is it essential to install any plugins to do this? How to enable mute tab in Google Chrome? Is there any feedback to use this feature? Thank you
