Weird bass effect along the wall

Hi all,

I am just setting up my studio with a small band. I have just put up some acoustic panels and bass traps. It made a big difference and the echoes are all but gone.

BUT my bassist noticed that when he goes up against the wall in the room (we checked 2 of them) and the bass sound seems to intensify so much that it becomes hard to hear anything else. I mean, it really is seriously invasive and seems to run up along the wall. The center of the room is great, but about a foot along the wall of terrible.

The ceiling is high (~ 4m/12ft) and I have placed bass traps in all the top corners, but not much acoustic paneling above 2m/6ft.

So clearly I did something wrong.

The room itself is 3x4m (10x12ft). Here are some pics.

You can see the bass amp which is in the back corner of the room. Bad placement? It’s got about a foot clearance on either side and maybe 6inches to the acoustic tiles in the back and nothing in front of it for about 4 feet (4 feet between it and the drummer).

Any advice ?

Thanks in advance.

Your issue is not echo. Echo is a repeating signal. Your issue is reverberation and will require a 65% surface area coverage of all 4 walls and ceiling. The “technology” you have used does not have the proper rate band level of absorption to deal with your small room large source output room.

Thanks. Unfortunately I cannot spend the thousands of dollars required in your link.

I’ll see what I can do otherwise.
