Bass is leaving the room. Down the corridor, toward the toilet, toward the entrance, to the neighbours. That's a problem you don't solve by turning it down when it gets louder. Frequency has to be understood.

So from this Saturday and for the next two months we're running an acoustics workshop. Ten people, no lecturers. Everyone comes with knowledge someone else doesn't have, and that's the whole format. No prior experience with acoustics needed. What you already know is enough — plus the wish to learn more.

We do three things. The basics of building acoustic panels: what actually absorbs sound and why thickness isn't a detail. Active cancellation of low frequencies: two subs in the corridor, microphones and a system that works against the bass so it doesn't cross the boundary toward the WC and the entrance. And software for acoustic simulation: you put walls, elements and speakers into a virtual room, get a calculation and a heatmap by frequency, then play around until the room sounds right. Then we do the same in the real space and we have a sound everyone will love.

It's not a course. No grades, no certificates. There's a room the bass leaks out of and ten people who want it to stay inside.
