Yasushi SUKO is a doctoral student at the Faculty of Social Sciences/Psychology, Tampere University, Finland. He studies the effects of nature experience on people, especially the restorative effect of repeatedly listening to natural sounds (e.g., birdsong, the sound of a running river, etc.). He is currently a member of the EnviWell Research Group, directed by Professor Kalevi Korpela.

 

In this episode we deep-dive into the acoustic stimuli and elaborate on the various potentials listening to specific sounds can have for health promotion, restoration and wellbeing. The roles of nature sounds are discussed and practical applications both for clinical and non-clinical contexts are investigated.
