— How Walking Sounds Reveal Age ‘

Secondary Research

‘ Due to joint stiffness and a loss of muscular mass, older persons walk more slowly and with more weight. As the body’s capacity to absorb contact diminishes, the force of the step increases, causing a slower cadence and a more noticeable footfall sound. ‘

Age-Related Changes in Gait: Footsteps and Footfall Frequencies Across the Lifespan, Emma Johnson, 2018

‘ The older group’s average interval between steps was 0.9 seconds, whereas the younger group’s was 0.6 seconds. The distinctive sound of older footfall is produced by a slower cadence and a greater impact. ‘

‘ Individuals over 65 often produce steps that are 50% louder than those of younger adults, especially when walking on hard surfaces like stairs. ‘
