Car feels bumpy?

I used to get this on my old '89 100Q and my less old '95 A6QA.
I always assumed it was some kind of "resonant frequency" on the
shocks that would magnify small surface irregularities.

I only noticed it after I put in new shocks (Boge Turbo Gas both
times), not with the old worn shocks.

Never really bothered me enough to look into it.
