ok card in the spoke is a good term.
here is a test you can do to locate the area of the noise, when driving roll down one window at a time, if its in the left front the noise will get louder when the left front window is open, and same with the rest, or you sit in different spots in the car when driving to see if the noise is loudest from drivers seat , that will narrow the noise from 4 possible places to just 1 . then,
since its rotational, it will be limited to a few things outside of the weird out of this world type scenario,
things that rotate when driving are,
- wheel bearings
- wheels and tires
- cv axles
- brake rotors or drums
so that is it, honestly if you had it to a shop and they can not find the consistent noise, that tells me you need to go to another shop, look how many ideas i have thrown out to you and i am no where near the car.
