'Acousticians' have aided the design of Tottenham's new 61,000-capacity stadium in order to help fan chants sound even louder and more clear, say architectural firm Populous.
They claim the new venue is designed to be more like a concert hall than a football stadium in order to create 'more clean reverberation times' so songs last longer.
Christopher Lee, Populous' managing director EMEA, said in an interview with GQ: 'The studies we've done show when you start breaking up acoustics everyone gets out of sync so they stop singing.
'So once they create acoustics where they don't break down, the reverberation times are quicker, they last longer and get louder.
