This is a richly intriguing phenomenon, with interesting implications!

For those interested in reading more, this article (on stochastic resonance's potential importance in biological sensing) is edifying: https://www.physik.uni-augsburg.de/theo1/hanggi/Papers/282.p... (Hänggi, Peter. "Stochastic resonance in biology: how noise can enhance detection of weak signals and help improve biological information processing." ChemPhysChem 3.3 (2002): 285-290.)

(Perhaps this is an example of how biological systems can value accurate sensation so highly that they invent ingenious sensing schemes to achieve high performance.)
