Noise suppression in offices

I remember a long time ago coming across an office environment where there was a 'white noise generator' employed to effectively mask the sound of 50 or more phone conversations going on at the same time in a large room. I saw a similar device used in a doctors surgery - the aim was to stop people in the waiting room hearing details of the conversations going on in the surgery itself.

The device was basically a speaker (or a few of them) giving out a constant stream of low-level noise which effectively muffled conversations and stopped them being overheard from a distance. Obviously the noise itself wasn't supposed to be too annoying or else it would be counter-productive.

I don't know what the correct name was - noise suppression and white noise seem to turn up all sorts of results on Google. Does anyone know what the official term is ?

Thanks,

Thanks for the quick reply - that's exactly what I was looking for. I bow to your superior googlability.

It's starting to sound very boards-ie around here these days - I thought "what you said" was the web equivalent of "yeah, but no, but yeah, but . . . wotevvva"
