I clap my hands in my room(around 12'x15') and I hear the ring for about a split second and it is pretty loud.
I made two 2'x2'x1" panels covered in felt and put the on the walls, helped a tiny bit, still needs more though.
I plan on purchasing a few Aurelex foamies but feel like I am wandering and following advertisements misguided.
Where can I start researching about tuning my room aswell as figuring out where the worst spots in my room are that are reflecting noise the most?
Thanks.
