Thread: Very important......re: New stadium

There has been a lot of science written on the thread and well done to you all but I want to correct you. . . . especially BASSKADET.

A stadium is a completely different kettle of fish to an Opera house or Concert hall. The materials used & such will have little effect within a stadium because you have crowds of people sat on all sides with a semi-open roof.

I know for a fact that the materials used do have a MASSIVE effect on the noise levels. . . A team of the most highly paid engineers were hired to make sure the Emirates stadium was so quite you could enjoy a nice glass of wine and a pawn sandwich followed by a little nap without any interuptions.

I've been there and I can say what an amazing job they did, I was behind one goal, and I heard a coin fall out of the pocket of a man sitting behind the goal at the other end. I even knew which coin it was (a pound coin). It's amazing that new ground.

Seriously, we should make sure that they work on atmosphere and don't f*ck up what we have at the lane.

Thanks GUSINTHEUK!!!

That might be true in the boxes, etc, but fundamentally building materials, while making a huge effect on sound, are not what are important in the arena itself, other than in the roof. Its more the shape of the stands & the amount of people in them (not just because more = more noise but also because more people will absorb any reflections).

Anyway, I don't disagree with anything being said, I really want the new gaff to be as loud as possible. When you build a room to deaden sound you use particular materials and make the surfaces as irregular as possible, with as much surface area as you can to absorb reflections &, or, direct them away from areas where they become a problem. That doesn't make it 'silent' it just completely removes any 'reverberation' from the room, which results in an unnatural sound.

To make a room 'soundproof' you build a room & surround it with materials that effectively create an air pocket all the way around the room. It is actually very difficult to 100% remove any outside noise from a room & in an ideal world you would surround it with a vacuum. Not easy.

However, there are certain things you could do to maximise sound for sure, I'm just saying that it is not the same thing as you would do in a music venue or Opera house design. The roof could be made as flat as possible and shaped to reflect sound back into the arena. Flat, shiny surfaces reflect sound best such as certain metals and glass do a better job than concrete. Also, Hollow metal rafters would resonate at certain frequencies and have an effect also.

However, the best thing to do (other than the roof thing) is place microphones in specific places to pick up the crowd's ambience & overall sound & play it back over equally carefully placed speakers. I think they might do this already tho because, if you look next time you're at the Lane, you should see mics hanging from the roof above the crowd. It is obviously to pick up crowd noise for television broadcast but they would be daft not to use it within the stadium itself.

However, I know nothing about stadium design but I do know about sound & I am not talking rubbish.

I'm not trying to tell people not to write anyway, I think we should, just don't think that what applies to the Sydney Opera House would apply in the same way here & not to worry too much as I'm sure they'll get it sorted. I have already written my letter to them on the subject & am awaiting a reply.


. . . a nice hollow floor might be good also for when we stamp our feet. That would turn the stadium into a massive 'drum' & could even be 'tuned' to get the nicest sound! Now that would be pretty cool!

Not really, I've just hardwired my brain to my computer . . .
