They are produced under the distal portion of the cuff, by the systolic reopening of a completely collapsed
artery. Note that the sudden tensing of the arterial wall (and its resulting sound) can only occur between
systolic and diastolic pressure because values above systolic will keep the artery collapsed, whereas values
below diastolic will keep it totally open (and, thus, silent).
