We investigate the effect of random and nonrandom disorder on the properties of periodic media. Specifically, we show that the complex transmission is particularly sensitive to whether the disorder is truly random or not. We exploit this effect as a flexible and efficient test to detect subtle biases in sequences of random numbers. Based on this approach, we suggest the implementation of a simple physical device requiring single-frequency analysis.
