I live in an old apartment building, so noise was the main thing I was worried about. The top is fixed into a main ceiling beam, and after trying out a few different tension cords, it’s quieter than expected. Most of the sound is just the ball itself.

The ball still moves more than I’d like, but making it tighter adds too much vibration.

Bit of a Frankenstein setup for now, but it works.
