Cable noise?
Don't forget that all these esoteric materials, especially
the high voltage types, demonstrate a pretty active
triboelectric effect. I assume the spectrum drops a lot
with the distributed capacitance, don't know how much.
When the cable is first manufactured, it's pretty tight, so
quiet.
But when the cable ages and loosens up, it can start to
become noisy.
If you need low noise cable, you may wish to include such
performance in your purchasing spec.
