~I'm not sure where this topic should go~

Does anyone know why Chinese variety shows only allow one microphone through at a time? What I mean is, unlike Korean and Japanese variety shows, Chinese shows leave out background noise. 

So, if there is any laughter or side comments the viewer cannot hear them; however, there are added sound effects. Is there a technical reason for this method, or is it more appealing to their Chinese audience, as most Chinese dramas are dubbed? 

Also, I am sure this might not be the case for all Chinese variety shows.

Examples:

  • Idol Producer
  • Who's the Murderer
  • Keep Running
  • Fighting Man
