At least you use the word "plausible". A nicer way of saying impossible. How do you explain that when I am in an area that has no cell phone reception I don't hear the noise?
Mind over matter. This claimed ability of yours is unknown to science, and the signals involved are well outside of the presently established limits of human perception. There is a name for the belief of some people that they are affected by electromagnetic fields of the type used in mobile communications: idiopathic environmental intolerance with attribution to electromagnetic fields, formerly electromagnetic field sensitivity.
Have you ever subjected this hypothesis of yours (that you can 'hear' mobile phone and wi-fi signals) to blind testing? That is, where the knowledge and control of whether the signal is present or not is held only by someone else, and not you, and you report to them your subjective sense of whether the signals are present or not?
Blind and, better still, double-blind testing has been performed on study participants who self-identify as sensitive to such signals. There is no evidence that they can actually detect the presence of radio- and microwave-frequency radiation.

If you put participants in an isolated area near a mobile phone tower and tell them during the first half of the observation period that the tower is radiating a signal (but is actually switched off), they will report being adversely affected. Switch the tower on, while telling them that it is being switched off, and they will report feeling better. i.e. How people feel around mobile telephone equipment is strongly governed by their
belief in the presence of such radiation, and not by its actual presence.
