Can the soothing chirp of birds or the rustling of leaves counter the stress of modern urban life? According to a study from the University of the West of England, while nature’s sounds reduce stress and anxiety, traffic noise can diminish their positive effects1.
The Experiment
Researchers tested how different soundscapes influence stress and anxiety in 68 participants:
- Pure nature sounds (e.g., birdsong).
- Nature sounds with 32 km/h traffic noise.
- Nature sounds with 64 km/h traffic noise.
Participants self-reported their stress, anxiety, and mood levels while exposed to these soundscapes.
Key Findings
- Listening to pure nature sounds resulted in the lowest levels of stress and anxiety and the greatest improvement in mood.
- Adding 32 km/h traffic noise slightly increased stress and anxiety levels.
- Adding 64 km/h traffic noise led to the highest stress and anxiety levels, significantly reducing the mood-enhancing benefits of nature’s sounds.
Why It Matters
Natural soundscapes, such as birdsong, can help alleviate stress, promote relaxation, and improve mood. However, urbanization—characterized by limited green spaces and pervasive artificial noise—undermines these benefits. Traffic noise, in particular, interferes with the restorative effects of nature.
Implications for Urban Planning
The study suggests that reducing urban traffic speeds could have broader benefits beyond safety, potentially enhancing public health and well-being by allowing more people to experience the positive effects of natural sounds.
