They can play in smaller stadiums for temp reasons. But for home stadiums they have a lower limit.

Regarding just the ETFE roofing and acoustics, marketing indicates ETFE is more sound transparent than sound reflective:
"When sounds are produced in an enclosed space, the reflection of those sounds from the surrounding surfaces until the sound waves eventually dissipate is referred to as reverberation. Texlon® ETFE is an acoustically transparent material with a mass of less than 1kg/m2. This means that sound generated by building occupants passes through the ETFE foil and is not reflected back into the space below, unlike less acoustically transparent materials such as glass."

"ETFE building material is acoustically transparent. Reflection of noise created inside buildings is minimized. Trying to enjoy those spaces, where other harder materials (e.g. concrete, glass, …) reverberate noises, is more comforting when Texlon® ETFE is the application for roofs and facades."

Independent science/engineering crap dealing with atria noise, not stadiums/stadia (noise going out, but noise will be coming in too, for all the aviation fans):
"The results confirm expectations that, by virtue of their higher acoustic absorption, ETFE systems help to improve the acoustic quality in large halls such as atria. In comparison with glass or polycarbonate, rooms covered by structural skins such as ETFE have a shorter reverberation time, particularly in low and middle frequencies. However, the acoustic comfort in large halls cannot be fully reached by roofing structure only because of the surface of the roof only covers a limited fraction of the overall surface. In order to achieve optimum acoustic comfort, also the atrium walls need to be treated.
"One should also take into account that, although typical membrane structures have higher sound absorbing properties than hard materials such as glass (the use of materials such as glass and polycarbonate where ca. 35% more energy is reflected back to the room, in comparison with foil or textile membranes), they typically have poorer sound insolation (is mainly determined by mass). This can result in an increase of background noise levels in the hall if the building is located in a noisy outdoor environment."

Not a lot of excitement in these but he updates regularly so I'll post them when I see it.
That makes total sense since Paul Allen being the smart dude he was KNEW that fan noise could be a significant factor aiding the home team. Thus, he SPECIFICALLY had the stadium designed to augment the fan noise without amplification. Fan noise amplification was against the rules at that time. Since then, the league seeing what an advantage this gave forbade any team from constructing a stadium that would augment fan noise. Therefore, they would have to use a sonically transparent material OR for a straight dome find some way to deal with the fan noise either through insulation or reflecting the sound away from the field.
@TSFH Fan great info, thanks. Yes the ETFE will let a lot of the lower frequencies pass through it... the lower the frequency, the easier it gets through light materials like ETFE. But higher frequencies will have some energy reflected back into the stadium (such as screaming humans voices). So it won't be as loud as the Ed, but if the Rams can draw a decent home crowd like the Chiefs game, it will be loud enough.
Speaking of Chiefs.... Arrowhead is one of the loudest stadiums in the NFL, even though it has no roof. As the info posted says, the roof is only part of the equation - other surfaces such as the walls and floor also reflect sound. The seating bowl there (and here) is precast concrete so that will reflect nearly 100% of human screaming sound energy. Living here in SW Mo, I know the Chiefs sell out every game, which is also a factor, along with the product on the field.... Safeco was pretty quiet when we were blanking the Shawks
good times.
As to the airplanes, the ETFE will allow most jet noise through, but reflect some of the high frequency turbo whine away so there's that.

20 years? Or 10?
The going rate was top tier @ 30m per.
Even though terms were not released, studies valued the deal Arthur Blank got close to 30m with the Mercedes Dome deal signed before las season.
That's gonna be quite a stadium. I'm gonna have to fly to LA for at least one game.
Dodge really needs to step up. I mean seriously... Dodge "Ram" and "Charger" Kind of a no frikken brainer.
Sometimes people miss the obvious, but I'm with you on this it's a simple thing to figure out.

for those that never saw this footage. this is the first time i've seen it.

That video was creepy. I felt like I was watching an ultra sound of a baby in the 2nd Trimester!
Dodge doesn't own Ram anymore. Ram trucks are there own brand now. If Dodge buys it, it will just be Dodge charger stadium and I will absolutely lose my crap.
What's the round building with all the columns I see nearby in some of the photos being posted online?

That's the Forum, the Kings and Lakers used to play there. It's used for concerts now.
