A square wave is 100% distortion effectively. It's an infinite series of sine-waves (although the infinite series isn't needed to generate a square wave, just the sum of harmonics up to nyquist)

In the audible frequency and dynamic ranges, you realistically can’t perceive more than maybe 7 harmonics in a square wave and it sounds very different than a noise signal.
