ACOUSTICS

We have discussed everything about stadiums seating,facilities,roofs and so on.We haven't said anything about acoustics yet.Which stadiums make fans sound more impressive and which stadiums destroy this feeling?Which stadiums' acoustics are planned even better than concerts hall and which stadiums suck at acoustics?

I am very curious to listen to your views guys.I would also appreciate it al lot if you could post diagrams or else showing what you mean as far as acoustics are concerned.

Well before we continue, can we all just agree that the Little La Luz in Ashburton Grove has the best acoustics in all the world ever. It will stop these lump nuts spitting their dummies out for the next few days and boring the shit out of us.

This place has superb acoustics, by the way. Take a read.

http://www.bridgewater-hall.co.uk/

Its intricate shape is a vital ingredient in the acoustic perfection of the space and every concrete slab is subtly twisted to diffuse sound effectively in the upper parts of the hall. Too wide and substantial to be self-supporting, it is held in place by the bottom layer; a tensioning system of struts and tie-rods hanging into the auditorium like some inverted suspension bridge. Despite its visual impact, this inner steelwork is acoustically 'invisible' and has no influence on the quality of the sound.

Above the concrete ceiling, a huge acoustic void houses technical systems and winches for lowering the chandeliers. Higher still is the third, outer layer; a light steel framework supporting acoustic panels covered externally with thin sheets of reflective, highgrade stainless steel - relatively new as a roofing material, but lighter and infinitely more durable than lead, its traditional equivalent. The soffits are gently illuminated at night, creating the illusion that the roof hovers, magically weightless, above the building.

To ensure that the Hall's carefully designed acoustic remains cocooned from all outside noise and vibration, the entire structure floats free of the ground on almost three hundred, earthquake proof isolation bearings. These sets of mighty steel springs ensure that there is no rigid connection between the 22,500 ton building and its foundations. In the Hall's undercroft, a forest of foundation columns, each capped with a cluster of spring units, create a mysterious silent world as compelling and dramatic as any of The Bridgewater Hall's more public spaces.

Even the material of the seats was chosen with the acoustics in mind.

Come on, the thread has already been derailed by the 2nd post!

Steeper grandstands make more noise since the fans are all closer to the playing field. A roof or dome helps as well since it holds noise in and directs it towards the field. Seattle's Qwest Field was designed with increasing noise as a priority, the roof and stands are positioned so the noise is directed at the field, also the funny looking section at the end of the field has bleacher seats and cheaper tickets than other lower deck seats (you are stuck out in the rain) is kind of like a drum and increases the noise of the fans in that section.

Stadiums like Michigan stadium are big, but the giant open air bowl configuration dissipates noise. Also large 20,000 seater basketball arenas like the Dean Smith Center (AKA Dean Dome) arent known for being all that loud, supposedly a flat roof is better than a dome at directing the sound towards the court.

Husky Stadium is supposed to be the loudest College football stadium, I think they have reached 127 decibles (when they have something to cheer about anyway). Construction can also make a big difference, steel stadiums will be louder than a similar concrete stadium. Anything with steep stand, oddly angled portions and/or low angled roofs should reflect and retain sound pretty well. As far as college facilities go Husky, Autzen, Tiger Stadium, Ohio Stadium, and the Swamp are supposed to be the loudest from what I hear (and as far as games on TV go)

The Metrodome is far and away the loudest that I have been to (and been to on more than a few occasions). Clearing 120 decibels seems to happen quite a bit when the Vikings are doing well, during the '87 World Series got up to 125 for baseball! The low (about 180 feet above the field) acoustically insulated dome, and large portion of retractable seats on one side and fairly steep bowl certainly help us in the noise department.

Landsdowne Road, Dublin. The old one. I think this stadium held some sort of record for the largest human generated noise in Europe for a fairly long time, or something like that. At the right time, it could be exceptionally loud, especially at rugby matches. Despite Croke Park being nearly 35,000 spectators larger, it hasn't quite generated the noise in old Lansdowne Road.

I'm not really sure what made Lansdowne Road so loud and special. I guess the fact that the crowd could be less than two metres from the pitch in some places, the two open terraces at either end, the fact that the fans nearest to the pitch the whole way around the stadium were all standing (for rugby at least) and the fact that the whole stadium had been crammed into a site that wasn't suitable for a sport played on a rectangular field all added to it. A truely loud stadium filled with truely passionate fans, especially in the late-90s!

Acoustics in a stadium is really so relative. If you're playing before an audience of deaf mutes, then...:ohno: If you're playing before an audience of hysterical drama queens, then, of course, you'd get the highest decibels. It also depends on the roof/canopy situation, the material they're made of, and the prevailing winds that day.

I think the Birds Nest will be somewhat loud. But the Chinese are not really very vocal people, so you wouldn't get the same frenzy as you would in an English or Brazilian soccer game.

to me i think that the number one structural factor in loud stadiums are stands that go straight up...clearly we Americans dont really like roofs on our stadiums, but we can generate just as much noise. youll find here that some of the loudest places have stands that go up and up

A flat roof on a stand keeps the noise in, hense why at any British ground that has a covered kop has a flat roof. Two examples

In terms of football / soccer atmosphere I like the effect of a big low roof.
I was a regular at Highbury back when one of the ends of the ground "the Clock End" had no roof whereas the opposite end "The North Bank" did. Other than that they were pretty much identical.

Guess which end you went into if you wanted to sing songs and make noise. Simple logic really.

Turkish fans in general are noisy. Any stadium can be very loud depending on the occasion and the fans though.
Fenerbahce and Galatasaray fans are pretty much equal in terms of noise but Fenerbahce atmosphere seems a bit better. I think The difference is the stadium architecture. Fenerbahce is architecturally a noisy stadium i.e. steep stands, close to the pitch and a suitable roof. This type of design is particularly good for songs and chants as they catch on better if the sound resonates around the bowl rather than going into the ether. As far as I know the capacity is only about 50k but sounds bigger.

agree with Sercan. Although I've been to only a few reasonably good stadiums, I could easily see the difference here in Krakow. Our new stands are anachronic- yes. but they are exactly what Sercan said: pretty steep, roof is flat, hanging, based on metal and policarbonate panels without any supports and construction on the inside. And the difference in noise compared to the old uncovered stands is just huuuuuuuuge. For interested, example here:

Actually the acoustic is better at old Inönü and old Ali Sami Yen, because they have a concrete roof.
I think because of the roof construction under the roof the acoustic is bad at Sükrü Saracoglu. (The same is at Schalke Arena)
Because of that FB board plans to do something for a btter acoustic (still in planing phase)

Therefore the GS board wanted a stadium with a better acoustic. I think a special acoustic metal will be used for the roof.

Great video Michal
How many rows does the new stand have and how steep (°) is it?

EDIT: Michal, is policarbonat also good for the acoustic? Our new stadium will have makrolon

But one thing is nearly clear
There won't be anymore jumping fans at the east stand like it is today
The fan groups will be at the enzdone stands

But on the other side, the new one has a roof (special acoustic roof), stands are steeper (2nd tier is 34° like Wembley and Allianz 3rd tier) and sands are very close (6,2, and 8,2m Even closer than other new projects)

Hmm, what makes a stadium loud???

Well, first of all there's the physics behind the stadium accoustics.
So, for a loud good atmosphere you would want the sound to be reflected. Something that for the "quality" of the accounstics regarding music or concerts is usually rather bad actually. But for a loud and impressive stadiumatmosphere a low metal roof is pretty good. Anything that keeps the noise inside the stadium is helpfull, so ideally you would probably want a completely closed and low roof. Shaped in a way that the noise from the stand is directed down towards the pitch and the opposite side of the stadium.

The next helpful aspect is getting the audience as close to the pitch as possible. Then the noise is produced nearby. So theoretically very steep stands aren't even all that helpful in this aspect, because the steeper a stand is, the further up are spectators in the back and therefore also a little further away of course. So there would be an optimum somewhere, pretty steep, but also not too steep stands should probably be best. But steeper stands of course seem more impressive and psychologically people will probably be more animated to sing along when the antmosphere is impressive, a stadium with steep stands does seem larger. So probably because of the psychological effect steeper really is better in the end.

But the one thing that REALLY helps getting up the volume and atmosphere big time is terracing. The more people stand, the louder and better the atmosphere. For several reasons. When standing people follow the game more emotional, because they don't sit relaxed and don't need to get up, but instead shout and jump and sing more because they're standing allready. the atmosphere usually gets more emotional and more agressive, which is also a reason why terracing in many countries is not allowed anymore.
The other BIG factor and probably in fact even the more important one, why terracing makes the atmosphere so much louder is, that you simply have twice as many spectators in the same area, because people on the terracing each take half the space than those sitting. (the conversion from terracing to seats is 2:1) So people are much closer together and much closer to the pitch when they're standing, because the amount of people on the same stand is basically doubled in relation to seating. And if you've ever been to an older stadium, where most people are standing you will easily be able to tell the difference a large amount of terracing makes.
So if you want to increase the noise and improve the atmosphere in a stadium you should probably first and foremost try to increase the amount of terracing, if that is a possibility, because the amount of terracing really does have an immense effect on the overall stadium atmosphere.

The next aspect that usually helps, is not having many different tiers. If you have one big tier instead of two smaller ones for example, the atmosphere usually spreads out better. Because all the people are in the same tier and not up or down somewhere else on another one. And that helps create a more unified atmosphere when singing, shouting... whatever. And it helps avoid having too many little more or less isolated groups of fans singing by themselves in the stadium. One big tier naturally synchronises itself much better and easier than two smaller ones.

Well, those would be all the main factors concerning the stadium accoustics that I can think of so far...

Green Point Stadium was designed to take some of these design initiatives into account.
It has a double membrane roof with the outer skin being glass and the inner skin a fabric mesh. the glass roof is a double layer laminated glass structure with a membrane inbetween. Glass is excellent for the isolation of sound

Glass is excellent for the isolation of soundThat is a really spectacular roof at the Green Point Stadium, also because of the way it's supported.
What they did here in Aachen is actually a very basic and simple solution. They just put the metal roofcover underneath the steel carriers. This way it's practically 6 meters lower than it would have been otherwise. Plus it looks much nicer, because this way the steel structure isn't visible from underneath.
>>Here<< (http://www.aachen.de/de/stadt_buerger/bauen_planen/stadtplanung/bebauungsplaene/krefelderstr_soerserweg/_4_Schnitt_Stadiond.pdf) is an older pdf of a crossection. (It's not quite up to date anymore because of a few changes. But the roof is shown correctly.)
Behind the south stand, where the terracing is located, the back of the stand has been closed with glass to reduce noisepollution, which was a very imporant issue here, because the new stadium is so close to a residential area. The other sides are left open to allow the air to circulate. An interesting fact about this roof here is that they actually placed a concrete weights at the very inner end of the roof, to reduce the swinging because of wind or earthquakes. The concrete weights placed there are 7.5 tons for each carrier! They add up to 380 tons of concrete weights all together for the entire roof.
It really does seem quite strange to put hundreds of tons of ballast into the roof if you think about it, doesn't it?
But in fact it is a pretty clever construction.

An interesting fact about this roof here is that they actually placed a concrete weights at the very inner end of the roof, to reduce the swinging because of wind or earthquakes. The concrete weights placed there are 7.5 tons for each carrier! They add up to 380 tons of concrete weights all together for the entire roof.
It really does seem quite strange to put hundreds of tons of ballast into the roof if you think about it, doesn't it?
But in fact it is a pretty clever construction.

Well in Cape Town steel cables were used so that it was not purely a tensile structure. So during high winds in Cape Town, the roof can move up and down by about 1.5 metres!

The best acoustic is in the Besiktas stadium. They have the world record with 132 decibels. Just watch this:

according to fox sports, Qwest field reached the highest crowd noise ever recorded during the 2005 NFC championshipgame at 137 decibels

I have been to dozens of stadiums across the United States, and I believe Qwest Field in Seattle to be the loudest and most intimidating to the opposing team stadium I've been to. Seattle's Qwest gets my vote.

According to Guinness World Records, Arco Arena, in Sacramento, set the official record for loudest sports roar by reaching over 130 decibels on November 8, 2006 during a Kings game against the Detroit Pistons.

Of course that's just what's "official" as Guinness doesn't have equipment and people to record levels at all games.

Cape Town Stadium (turn up the volume)

Such a nice anthem.

Watching the Nebraska vs Washington game yesterday, I have to wonder if any place is louder than that. The camera was severely shaking when Nebraska had the ball. Even the announcers commented that they hope the place didn't come down. Don't think I've ever seen anything like that in a large concrete and steel stadium.

All modern stadia look more "solid" than they are, they all move and shake when fans jump and sing around on them. But that doesn't mean they're unsafe or anything. They should all easily withsstand the stresses and there's no need to worry they might collapse. The structures are just a bit more flexible than one might expect from "rock solid" steel enforced concrete structures and they in fact have to be somewhat flexible if they are to withstand earthquakes and jumping fans. But it really does feel a bit strange when you're standing there and the floor shakes a little underneath you from all the fans jumping.
Here's a really nice example that shows very nicely how much a stand can shake from jumping fans (at the end of the video).

I think he means Husky Stadium, which I believe has the highest documented decibel level for a stadium, in the 130s back around 1990. Clemson and LSU have been recorded in the high 120s as well.

The thing about Husky stadium is the upper decks are steel framed and use trusses to carry the seating as well as steel roofs which all reverberate like crazy amplifying the crowd substantially. Also given that it is a steel structure its inherently more flexible than a concrete one allow for some give which leads to movement in the stands, although it was designed to absorb and counteract those forces so it should be safe in all probability.

Yes, I was refering to Husky Stadium. And yes, that video sort of shows it, but it was crazy during the first quarter of the Nebraska game. To the point that the announcers couldn't believe how loud it was and how much the place was rumbling. One just kind of exclaimed, "Wow!", and Nebraska was kind of standing around. Then the announcer said, "We are literally shaking just as you're seeing on your screens. Its so loud I hope this place doesn't come down".
