Nearby forest soundscapes boost mood more than distant ones.

A study of 195 German students found that familiar local temperate forest sounds produced stronger short-term feelings of restoration and awe than acoustically richer tropical recordings from Panama.

Researchers from an international team including the German Centre for Integrative Biodiversity Research (iDiv), Helmholtz Centre for Environmental Research (UFZ) and several German universities tested how forest soundscapes affect mental wellbeing. The experiment involved 195 students in Germany who listened to one-minute recordings over high-fidelity headphones that varied by the number of distinct animal sounds and by geographic origin (local temperate forests versus tropical recordings from Panama). After each exposure participants completed validated measures of emotion, perceived stress and attention, and also rated pleasantness, familiarity and perceived species number. The study combined acoustic analysis tools with psychological scales to separate objective soundscape properties from participants' subjective perceptions. Key findings: - Sounds from local temperate forests evoked higher reported feelings of awe, restoration and emotional uplift than the tropical recordings, despite the tropical recordings having higher species richness. - Increased acoustic species richness enhanced some positive responses (for example, awe) mainly when the sounds were familiar to listeners. - Exotic or less-recognizable soundscapes, even when acoustically complex, sometimes reduced positive emotional responses. - Participants' estimates of perceived animal diversity did not always match objective species richness, and recognizability influenced outcomes. - The study used controlled short exposures and validated instruments; the authors note limits and call for further research on longer exposures, more diverse populations and multisensory contexts. Summary: The results indicate that familiarity and recognizability of local forest sounds are important drivers of short-term psychological benefits, and that acoustic richness alone does not guarantee stronger positive responses. The authors discuss implications for conservation and urban planning by highlighting the mental wellbeing relevance of locally familiar soundscapes, and they call for follow-up studies on long-term effects, broader demographic groups and combined sensory experiences.
