Sound dampening tips - neighbor friendly sim

Live in a townhouse with shared walls. Had to make my sim as quiet as possible. Here's what worked:

Impact noise:

1. ThunderMat under my hitting mat - huge difference
2. Added rubber horse mat under everything
3. Impact screen with proper slack (tight screens are louder)

Ball return:

1. Built a fabric chute instead of hard tube
2. Balls land on a towel in a bucket
3. No more "thunk thunk thunk" sounds

Equipment noise:

1. Projector in a foam-lined box (with ventilation!)
2. PC in a closet with extension cables
3. Soft-close for any cabinets

Result: Can hit balls at 10pm without complaints. Wife can watch TV in the next room without issues.
