Dortmund has one of the best atmospheres of any ground in the world ... for those who haven't had the pleasure the downward slopping roof 'pushes' the noise down and out onto the playing surface ... believe me it gets loud .... but it's not perfect as some sound gets 'bounced' back towards the ground as the roof drops much lower at the front ...
With atmosphere in mind the roof at Spurs is designed with a 'down' slope to project noise forward, but then opens up again to allow the sound to burst forward ... all designed by some clever guys in sound proof boxes ...
It's going to be the dogs dangles ....
FYI - The Emirates roof is virtual horizontal ... from a sound point of view it's utter shite .....
All the more important that the club allocate the right people to this stand then, and tell stewards to let us get on with it.
