Is your car MT or AT? I take it that you have an AT since you say "park".
If AT then it could be the torque converter. A while after (like 35k miles after) my transmission was rebuilt, it started to make a whining noise similar to what you described. I had the fluid drained and filled shortly after and the noise remained. My mechanic said it was nothing to really worry about especially since I had just done the fluid change. He explained it as a "minor" issue with the torque converter that won't cause any mechanical problems.
But since you say the noise still happens while in park, imna say that its your PS system. More than likely you have a leak with your PS system causing the fluid level to drop and then you get that noise after the PS fluid gets low enough.
