Sounds like the park end.Chris Dite knows his onions. He also knows that this development for United has not been designed for fans.
On another note, the room they mention, SoundLab, also exists in Manchester and its absolutely remarkable. Its a box in a box construction, so nearly 100% soundproof. If you turn all speakers off and spend to long in there you become quite disorientated and can hear the blood flowing through your own veins. Quite an odd sensation.
