I would like to refer to the contrasting effects of periodic rhythmic elements and non-periodic rhythmic elements as described in the book ‘The Power of Sound’ by Joshua Leeds under ‘Common applications of  entrainment’. Here, examples of periodic rhythmic elements are referred to as a stabilizing factor for our human system while non-periodic rhythm elements like traffic noise do the opposite and ‘jangle our nervous system, because the brain tries to categorize them.’
