Traffic Noise Found to Undermine Mental Health Benefits of Nature Sounds

A new study reveals that road traffic noise increases stress and anxiety, diminishing the calming effects of natural soundscapes.

The study, published in PLOS ONE, examined how traffic noise impacts stress, anxiety, and mood recovery in 68 participants exposed to various soundscapes.
Natural sounds like birdsong significantly reduced stress and anxiety, but the addition of traffic noise lessened these benefits, particularly at higher speeds.
Participants reported the lowest stress and anxiety levels after listening to nature sounds alone, while traffic soundscapes at 40 mph resulted in the highest stress levels.
Researchers suggest reducing traffic speeds in urban areas to preserve the mental health benefits of natural soundscapes and improve overall well-being.
The study highlights the broader implications of noise pollution on mental health, urging policymakers to prioritize greenspaces and soundscape conservation in urban planning.
