Room Modes: ODD Room Dimensions SHAPE Your Sound (And How To Deal With It)

bass traps and low frequency control

When was the last time you went down the acoustic treatment rabbit hole only to come out hours later with your brain on fire?

(Or just totally numb, followed by a confused nap..?)

I’m sure that’s what happened to our fellow sound nerd Lucas when he decided to shoot over an email.

In a nutshell he wanted to know what happens at the intersection of two room modes, when there’s a step in the geometry of the side walls and your listening position is placed exactly at the edge of this step.

If you’ve come across something similar, you’ll know exactly where Lucas is coming from.

Surely in front of the step, one room mode is created, and behind the step another one gets created?

How do you make sure that you don’t end up in a confusing mish-mash of these two room modes, and only have to deal with one of them instead?

It’s definitely an interesting question and solving this problem has more to do with getting back out of the rabbit hole and seeing the whole rabbit hill, instead of figuring out a solution while you are deep in it.

Let me explain what I mean in this week’s video.
