Not an audio engineer, but I had unshielded (thin) cables in my home speaker setup. If the cables were positioned correctly, everything was fine. Accidentally move them even a little, and there’d be a huge amount of noise, due to power cables going near the speaker cables. Switched to shielded (thick) cables, and there’s no noise ever.
Shielding has to do with the orientation of the ground wire in the cable versus the signal wire. In a shielded cable the ground wire completely surrounds the signal wire like a pipe. In an unshielded cable the ground wire is wrapped around the signal wire or run next to it.

Cables that are shielded like this are coaxial.
