Working on a 5,000 set concert venue beside the casino at Niagara Falls. The concert hall was completed a few years ago but never opened because it failed the acoustics test (too much echo) and we're changing the angle of the panels at the back of the theater. He's some photos of the work.
The panels are made of 6 pound fiberglass. Resin is poured on in patches so that we can screw on the clips that will suspend the panels. They are being changed from being flat against the wall to angled towards the stage. 3 layers of 3" mineral wool insulation is stuffed behind the panels. This was done on all 4 floors.
Behind the stage 2 layers of 3" mineral wool were placed on the wall behind the performers and large walls of insulation are going to be built on the catwalk above the stage.
Holes were cut into the ceiling to let the sound escape into. The angled panels hide the holes.
I've also included a couple of pictures of the finished product.
Real itchy work, it was a lot more fun building the actual venue! Cold as hell but at least I wasn't covered insulation fibers all the time!!

That is SERIOUS work, too much involved, you NEED a PRO Acoustics Consultant for that job, not just asking in a Forum.
Even if it´s the best Forum in the World 😉

We have a Acoustics Consultant who works in conjunction with the architectural firm. They measure with microphones and test using a huge bass speaker that you can't hear but you can feel when you touch an wall or chair. They're testing today but I'm not at work today as I'm going to the comic-con in Toronto with my kids so I can't get any pictures of that for you.
They've spent $800,000,000 so far on the venue (the government owns it) and it shows - marble floors, 800 yards or so from the Falls so they're not afraid to spend the money needed for an acoustics consultant.
I posted not to ask questions but to show you all, because I thought there might be some who were interested to see it. Having said all that you're obviously correct, a pro acoustics consultant is needed for the job. I should have included more info in my original post.
Good.
Was sightly worried you would save cents and spend Millions 😉
Keep us updated, show general view showing the whole seating area and stage.

did you say marble floors??
the next time your there can you get some pic's of the ceiling?
and this shot seems to show a cutout of the ceiling at the wall if this is any indication of the construction method used it reveals a big problem.

Out in the hallway, yes marble floors. Inside the venue carpet.
Yes this is a cut out in the ceiling. The cut out remains and will be hidden by the panels that are on an angle. The sound is supposed to go up into the cut out and dissipate above the suspended ceiling. At least that's what we've been told.
I'm at home today, not feeling well, here's some shots of the ceiling and the "clouds" stiff, cloth covered pieces of fiberglass insulation hung from the deck.
Suspended drywall ceiling. Typical build - eye hooks drilled into the q-deck. Hang wire through the eye hooks bent at a 90 degree angle with inch and a half channel 48 inches on centre, furring bar at a 90 degree angle to the channel 16 inches on centre. Looking at the picture of the ceiling I see hang wire tied together because it's not long enough. That's poor workmanship and may be against code.
It was found that most of the "rattling" that was heard on the sound test was because the jobsite primadonnas had just left their bx and conduit on our suspended ceilings. They'll have to come back and wrap all their wires so they don't vibrate with the music....
