The Healing Power of Nature Sounds: How Traffic Noise Can Thwart Their Benefits

Topline:

Listening to natural soundscapes may help decrease anxiety and stress, but mixed with high-traffic noise, the benefits can be overshadowed. Recent research reveals this surprising finding.

Methodology:

Researchers recruited 68 adults aged 18 to 42 from the University of the West of England Psychology participant pool.

They prepared three 3-minute soundscapes: one featured natural bird sounds, while the others combined natural sounds with traffic noise recorded at 20 mph and 40 mph.

Each participant watched a stress-inducing video for one minute, followed by three minutes of sound exposure. Immediately afterward, they filled out questionnaires to gauge their stress levels, pleasure scores, and anxiety.

For quantifying stress and pleasure, researchers used the University of Wales Institute of Science and Technology Mood Adjective Checklist. Anxiety was measured with the State-Trait Anxiety Inventory scale.

Key Takeaways:

The study found that natural soundscapes are strongly linked to the lowest anxiety and stress levels. Mixed soundscapes with 40 mph traffic noise were associated with the highest stress.

higher hedonic tone (pleasure scores) was observed after natural sound exposure, but these scores declined when traffic noise was added.

Notably, traffic noise nullified the positive effect of natural soundscapes on stress and anxiety across all ages and genders, regardless of a pre-existing preference for natural environments.

Practical Implications:

“Our study highlights that listening to natural soundscapes can lower stress and anxiety, but anthropogenic sounds like traffic noise can cancel out these effects,” the researchers stated in a press release.

They added, “Reducing traffic speeds in cities is crucial for individuals to benefit from nature’s mental health benefits.”

Limitations:

The study mainly included university students, which might have introduced certain biases. Participants might favor natural sounds due to their demographics, including age, sex, or backgrounds.

Disclosures:

No specific funding was provided for the study. The investigators had no conflicts of interest to declare.

What Does This Mean for You?

If you are seeking a natural stress reliever, consider environmental sounds like bird calls, waterfalls, or wind chimes. However, be mindful of your local environment and reduce exposure to traffic noise when possible. Even better, engage with nature directly. Spending time outdoors and away from the hustle and bustle of cities can significantly lower your stress levels.

Final Thoughts:

This research underscores the intricate relationship between natural and urban sounds and their impact on mental health. By curbing traffic noise and embracing nature, we can unlock natural stress relief and enhance our overall well-being.
