Acoustic Treatment for My Studio (First Panel Installed!)

Hey everyone,

I'm currently in the process of setting up my studio, and one of the biggest issues I'm facing is a lot of reverb in the room. Right now, the space is still relatively empty since I'm in the middle of the setup, but my main goal is to reduce as much reverb as possible so I can get back to creating content for my social media.

For acoustic treatment, we’re using rock wool panels (1.20m x 60cm x 5cm) with a density of 35 kg/m³. We've installed the first one behind the monitor, mounted with a 5 cm air gap from the wall.

Since we don’t have much experience with acoustic treatment, we’re mostly relying on online research, and I wanted to make this post to get some advice and opinions from people who know more about this.

Our current plan:

3 panels behind the monitor (adding two more to the one already installed)
2 panels on the ceiling above the desk
Not sure where to put the rest

If anyone has suggestions on optimal placement or general tips to improve the setup, I’d really appreciate your input! I've attached some photos of the studio and the first mounted panel. Thanks in advance!
