Stochastic Resonance

Stochastic resonance is a phenomenon where adding a certain amount of noise—or random fluctuations—to a system can actually enhance its ability to detect weak signals. Imagine trying to hear a faint radio station; a little background static can sometimes make the signal clearer, not more confusing. In many systems, noise helps surmount thresholds that would otherwise prevent the detection of faint signals, making the system more sensitive and improved in its response. This counterintuitive effect shows that, under the right conditions, randomness can aid in processing information rather than hinder it.
