Stochastic resonance is the phenomenon in which random noise can amplify a signal, like putting static over a photograph too faint to be seen can make it visible, and human perception already makes good use of this

The signal is amplified because the noise interacts with the pattern irregularly and thus the two “resonate” to produce something stronger than either alone.
