Concept question - What is noise?
Noise is definetly undesired, but not incomprehensible.

The fact that noise is comprehensible is the reason we talk about it. Cosmic Rays might be present, but they have no effect on an old mechanical clock. Would you consider them "noise" when you read the clock?

You might call that loud disturbing sound that you hear "noise". A deaf person would not consider that noise, because it's incomprehensible.
