Grey noise may be harmful if you listen to it during long periods of time. Programs like skype are famous for having gray noise. It is recommend that you download and install an "anti-gray" noise program. This program will reproduce wavelengths opposite of that of gray noise causing it to cancel and therefore not harmful to the user.

Gray noise spectrum

Grey noise is random noise subjected to a psychoacoustic equal loudness curve (such as an inverted A-weighting curve) over a given range of frequencies, giving the listener the perception that it is equally loud at all frequencies.

This is in contrast to white noise, noise which is in fact equally loud at all frequencies but not perceived as such due to psychoacoustics.
