Acoustic Foam Panels For Restaurants And Office Spaces - What You Need To Know 

I've been reading up about "flutter echo" and I know it happens in small rooms, I've had rooms that had REALLY bad flutter echo problems. I'm finding a variety of different descriptions and definitions on the internet. I know Flutter Echo is usually repeated in quick succession between two surfaces close to each other. Now is that really a type of reverberation or would it still be considered an "echo"?

great info! which sushi bar is that? I'd like to visit
