Contrary to a common belief, the presence of white noise can actually unmask sounds:
Good noise, bad noise: White noise improves hearing -- ScienceDaily
Does this mean that "privacy" measures used in open-space offices have the opposite effect?
Maybe, for a certain range of levels, but if the masking noise is strong enough, probably not.

Is "strong enough" going to be problematic or intrusive is another interesting question

As far as I know about hearing, there are mainly two types: selective and analythical.
The former makes it possible to 'filter out' surrounding noises, the latter includes everything into a 'frequency response analysis'. Adding (coloured) noise to sound will have different effects and results on these types of hearing.

That's a novel thesis. With direct application to many hearing questions. If you can show a valid basis, you should submit a paper to the audiology publications.
