Are you sure it isn't the alternator? You could take off the alternator/ p/s belt off and idle it for a bit (don't leave it running too long and drain your battery), and if the noise is gone then my guess would be the alternator. Sounds like it has bad diodes. And if the noise doesn't change while turning the wheel then it won't be the p/s pump.
