A randomised outdoor study at Treborth Botanic Garden, Bangor, investigating whether directing attention to natural sounds alters their restorative effect.
Studies 1 and 2 both took place in the laboratory, using recorded soundscapes delivered through headphones or speakers. Study 3 moves outside, into a real natural environment where participants hear the actual soundscape of a botanic garden in Bangor, Wales.
The central question is about attention. When you sit in a green space, do you naturally direct your attention towards the birdsong, or towards passing cars, distant voices and other human sounds? And does it matter which you attend to?
This study tests whether a brief, structured directed listening intervention asking participants to focus on natural sounds specifically, produces greater psychological benefit than free attention or attention directed towards anthropogenic noise. If it does, this has practical implications for how nature-based wellbeing interventions can be designed and delivered.
Attention Restoration Theory suggests that natural environments elicit involuntary attention, allowing directed (voluntary) attention to recover. But most tests of ART do not ask whether explicitly directing attention changes the experience. Some research in mindfulness and contemplative practice suggests that the quality of attention brought to an experience can profoundly shape its effects.
Nature-based mindfulness practices (such as forest bathing or mindful birdwatching) are increasingly popular, but the evidence base for their specific mechanisms is thin. This study provides one of the first randomised tests of whether directed attention to natural versus anthropogenic sounds within the same acoustic environment produces different wellbeing outcomes.
All sessions take place at Treborth Botanic Garden, on the Menai Strait near Bangor. Treborth is a working botanic garden with woodland, meadow and wetland habitats, and supports a diverse bird community throughout the year. It is publicly accessible, situated within the University estate, and offers a realistic urban-adjacent green space representative of the kinds of environments most people can access.
Participants are seated at a fixed, sheltered outdoor location within the garden for the 15-minute intervention. Passive acoustic monitoring is conducted simultaneously to characterise the soundscape each participant actually hears.
This study is part of a broader initiative treating Bangor as a city of wellbeing — using the city's natural and green spaces as active research environments.
The study uses a three-arm parallel randomised design, with participants assigned to one condition only. This between-subjects approach avoids carry-over effects from switching attention strategies.
| Parameter | Detail |
|---|---|
| Design | Three-arm randomised (between-subjects) |
| Target sample | N = 105 (35 per condition) — data collection complete |
| Setting | Treborth Botanic Garden, Bangor |
| Intervention duration | 15 minutes directed listening |
| Session duration | Approximately 60 minutes total |
Measures are taken before and after the 15-minute intervention, allowing change scores to be calculated:
After completing the questionnaires, participants are invited to respond to two open-ended audio-recorded questions about their experience. These responses will be analysed using Reflexive Thematic Analysis alongside the quantitative data.
Passive acoustic monitoring data collected during the session will allow us to link participants' perceived bird diversity with the actual acoustic biodiversity present.
Data collection for Study 3 is complete. A total of 105 participants took part across three groups (35 per group), at Treborth Botanic Garden, Bangor.
This study was conducted in collaboration with Percy Joyce (MSc Res Student), whose project within the study focused on knowledge and engagement with natural soundscapes. My analytical focus for this study is on emotions, perception and cognition based on mindful engagement with natural sounds.
Analysis is now underway. Results will be submitted for publication on completion.
