bandwidth requirement would (mostly) be identical to stereo audio transmissions.
All surround encoding takes place within the audio channels.

So the questions remains: what noise figure (distortion) would be accepted?
No one will accept dolby surround in telephone quality,

You won't be happy with noise figures below 40 dB. In original Dolby surround
encoding the rear channel will be companded, so this channel relates more to
distortion than to noise figures.
