It is about communication engineering.

Well, noise is noise, and distortion is when your signal is so strong that the measuring or recording device cannot handle it all, and it's waveform is sheared... when you turn up the 'gain' on a guitair amp, you are amplifying the signal, and the speaker can only respond to a certain magnitude of wave.. i dunno, though,

Noise is defined as any signal that is unwanted. If you are transmitting a pure 1kHz tone for example, then at the receiver anything other than that 1kHz tone is considered noise. The term noise typically refers to signals with random fluctuations in amplitude with respect to time in general.
If however, the communication channel or any part of the transmitter/receiver circuitry is non-linear, then the shape of the signal will change from being a pure sinusoidal 1kHz tone being transmitted in this case. Any such change in the shape of the waveform essentially means that the signal is no longer pure but has additional frequency components (called harmonics). This is called distortion of a signal.

Noise is just unwanted modulation. Distortion is when the signal you receive is, well, distorted.
Think of the traffic reporter sounding like he's beating on his chest while he talks from a helicopter. That's distortion. The wind noise that's drowning him out is noise.

noise is the unwanted signal that gets superimposed wit the information signal..distortion may b termed as the cause of the failure of the circuitary used which disturbs the regular pattern ...it may lead to a deviation an the signal but its not external like noise
