I'm thinking of setting up a guitar practice room in my basement. I'm wondering if the sound is going to be horrible due to all the concrete? Does anyone have any tips for setting up a music room in a basement?

Yes, the hard surfaces will cause problems - Room modes will be very strong. So at any position in the room, certain bass notes will be very strong and others will be very weak. The tonal balance will change in different places in the room - What's weak in one place will be strong in another and vice versa. Fixing that requires large panel dampers and or bass traps.

And the hard flat surfaces may also make the treble sound shrill. That's much easier to solve, because any sound absorbent material can fix high-frequency reflection problems. Acoustic wedges, thick furniture and carpets can all be used to damp medium and high frequencies.

So install lots of damping. And sit very close to your speaker.

Hi Wayne, thank you for your helpful suggestions. I'll take a look around at dampers. Would they need to be in the entire room or just the section that I plan on sitting in? I do have thick furniture in the basement, but no carpets.

This is such a good point because I have also been thinking of setting up a similar room in the basement, but not necessarily for practice. Hopefully setting it up correctly isn't going to be too costly because I only intend to use a little space.
