Abstract
In response to a challenge in a recent paper to measure the propagation speed of the wave of collapse of an array of dominoes (the Domino Effect), a novel method of measuring the speed of such waves has been developed using sound recordings of the collapse and DEMON (Detection of Modulation on Noise) analysis to extract the frequency of domino impacts and hence the speed of propagation of the domino wave. This paper presents this method and a discussion of the other published measurements and models and some comments on the precess of mathematical modelling.
