使用一个简单的范例模型来说明“随机共振”标签下的效应的一些一般属性。特别是，对透明模型的分析表明：1）添加到较大信号中的少量噪声可以极大地提高对信号的响应，但是 2）添加到较大噪声中的微弱信号不会产生实质性的附加响应。从模型得出的结论说明了一般结果：随机共振效应并没有为比噪声小得多的信号提供影响生物学的途径。进一步的分析表明，在随机共振效应显着的条件下，小信号对生物学上重要的化学平衡变化的影响。
A simple, paradigmatic, model is used to illustrate some general properties of effects subsumed under the label "stochastic resonance." In particular, analyses of the transparent model show that 1) a small amount of noise added to a much larger signal can greatly increase the response to the signal, but 2) a weak signal added to much larger noise will not generate a substantial added response. The conclusions drawn from the model illustrate the general result that stochastic resonance effects do not provide an avenue for signals that are much smaller than noise to affect biology. A further analysis demonstrates the effects of small signals in the shifting of biologically important chemical equilibria under conditions where stochastic resonance effects are significant.
