I'm not sure, undoubtedly the sounds of the event are important and as I said to you previously, after my last experience, I would choose the curva nord over any other part of the ground on future trips, but it's a visual that you're reacting to. I didn't mean how could he enjoy the occasion, that would be ridiculous, I meant how could he follow the intricacies of the game and so on much in the same way as deaf people can enjoy concerts because they feel the vibrations and so on but I would think it has the same problem of it being mainly a medium for one sense. Maybe it's a lack of understanding on my part to but as I said I was asking from curiosity not to offend and as they say questions are the biggest shield against ignorance.
Edit: Just so you know I'm not saying it's a bad thing for him to like it, quite the opposite, if he gets enjoyment out of it then it's as great as it is for anyone else who likes it, I was just curious as to how it would work for him and I would hope I haven't caused offence in asking.
