Noise from driveshaft ?

[Veteran]

Hi all, need some opinions.

I normally drive with exhaust in race and music on so don’t always hear noises emanating.

Today I went for a run in the mountain passes. .Music off at about 100 mph I can hear a audible rrrrrrrrrrrrrrrrr sound emanating from below center of car.
As i slow down the sound slows down till it disappears at say 20 mph.
it’s not very loud but definitely audible. It’s definitely mechanical and not exhaust.
It changes tempo with speed.

Could it be the driveshaft u joint ?
Any way to test ?

Hard to say without hearing the noise, but some have experienced something similar and it turned out to be a label on the driveshaft coming loose and flapping against the tunnel as the shaft rotates. You might want to take a look under there.
