Room impulse response question

[EAD86]

Let's say I had a few thousand dollars to spend.... What's the closest I could get to a room with an impulse response that's like white noise with a decaying exponential envelope (see below)??

That's a pretty broad question. What is you room, how extensive, how much room can you give up, how much grief will any significant others give you, how important are asthetics?

 

I just got done covering my room in pink fluffy which is by far the most cost effective and best performing. But even that is not perfect, and I exceeded the wife's tolerance yet again... But it sounds great. 😊
