Can a garage serve as listening room?

Based on the year of construction, the concrete floor may have a 1/4" per foot sloop to the door. If it does, light weight concrete can be installed to level the floor out. The steel door can me treated with insulation which is sold at one of big box hardware stores. Electrical issues may need to be addressed. Also changing the the garage to habitable space, as it relates to the Building Code (s) is another issue. If you avoid the code, add a smoke detector.

Good Luck

I am in the process of converting mine to a dual AV.. 2 channel room. I will keep you posted....PT

Thanks Peter, I encourage anyone who really wants a dedicated room to try to make it happen as it's such an important factor and really can make such huge improvements in the sound. Good luck guys.

Several years ago I turned a full-walled 10.5' x 12' 3rd garage stall into a recording studio for my younger daughter. To soundproof the room, I removed the original 1/3" drywall and added mass-loaded rubber sheeting overlaid with two layers of 1/2" drywall. I framed in a wall just in front of the roll-up garage door and applied the same treatments. Not only did the room become isolated from almost all outside noise (it also worked the other way) but the room response flattened out tremendously.

When she left for college I considered tearing it out, but ended up using it as a small dedicated 2-channel analog room. Just one chair, one rack, two speakers, lots of LPs and me. I only wish that I had added a window for a little natural light, but otherwise it's great.

I'd be very carful about a listening room in the garage.

The poor transmission of sound could be exhausting and muffled.
