The next time you find yourself daydreaming during a commute or trying to visualize a peaceful scene during a yoga session, take a moment to listen to your surroundings. It turns out the background noise of our lives—from the melodic swells of a playlist to the constant hum of city traffic—does more than just fill the silence; it actively reshapes the “theatre of the mind.”
A groundbreaking study published on March 30, 2026, in Humanities and Social Sciences Communications reveals that everyday auditory environments significantly influence the vividness, emotional tone, and even the perceived physical dimensions of our mental imagery. Researchers from Murdoch University and the University of Sydney found that while music acts as a powerful catalyst for positive and expansive imagination, even the gritty drone of traffic noise can make our internal visualizations more intense, albeit with a less pleasant emotional edge.
Mapping the Imaginary Journey
To understand how sound impacts our internal world, researchers recruited 107 undergraduate students in Perth, Australia. The participants were asked to watch a brief video of a person walking toward a mountain—a simple prompt designed to seed a narrative. Afterward, they were instructed to close their eyes and continue the journey in their minds for 90 seconds.
During this period of “directed mental imagery,” participants were exposed to one of four acoustic environments:
-
Music
-
Traffic noise
-
A combination of both music and traffic
-
Silence
The results challenged the long-held assumption that silence is the best canvas for the mind’s eye. Both music and traffic noise increased the reported vividness of the imagined scenes compared to silence. However, the quality of that imagery differed sharply depending on the source of the sound.
The “Shape” of Sound: Time, Space, and Emotion
The study found that music didn’t just make images clearer; it changed the “spatiotemporal” properties of the imagination. Participants listening to music tended to imagine themselves traveling for a longer duration and over a greater physical distance.
“Music appears especially important for shaping emotional content and imagined space and time,” noted Dr. Steffen Herff of the University of Sydney, a co-author of the study.
Traffic noise also boosted vividness and imagined distance, but it lacked the “emotional lift” provided by music. More interestingly, when the two sounds were combined, the traffic noise appeared to “blunt” the positive emotional benefits of the music. This suggests that a noisy environment doesn’t just distract us; it fundamentally alters the emotional texture of what we are thinking about.
Key Findings at a Glance
| Sound Condition | Vividness | Emotional Tone | Spatial Perception |
| Silence | Baseline | Neutral | Baseline |
| Music | High | Strongly Positive | Expanded (Further/Longer) |
| Traffic Noise | High | Neutral/Lower | Expanded |
| Combined | High | Muted/Interfered | Mixed |
Why Our Acoustic Environment Matters
Mental imagery is not just a tool for daydreamers. It is a cornerstone of cognitive behavioral therapy (CBT), relaxation techniques, and professional athletic training.
“Our findings suggest that everyday sounds, especially music and noise, can actually change the way we imagine things,” says Associate Professor Jon Prince of Murdoch University. This has immediate implications for “imagery-based” interventions.
For instance, a therapist’s office located near a busy intersection might unintentionally influence a patient’s guided visualization. While the traffic might make the imagery more vivid, it could simultaneously make it harder for the patient to achieve a positive emotional breakthrough.
“The results may apply to relaxation, role play, visualization, and psychological therapy,” explains co-author Ceren Ayyildiz. If clinicians and practitioners can control the acoustic environment, they may be able to better “steer” the imaginative process toward healing and stress reduction.
A Balanced Perspective: The Limits of Noise
While it might be tempting to conclude that traffic noise is “good” because it increases vividness, experts urge caution.
“This study adds nuance, showing that noise can sometimes change mental imagery in unexpected ways, rather than simply helping or hurting in a uniform manner,” says an independent reviewer familiar with the research.
It is important to distinguish between vividness and well-being. While a car horn might make a mental image “sharper” due to increased arousal or alertness, decades of public health research have linked chronic urban noise to higher cortisol levels, sleep disturbances, and cardiovascular stress. In contrast, nature sounds—though not the focus of this specific study—have been consistently associated with parasympathetic nervous system activation (the “rest and digest” mode).
Study Limitations
As with any laboratory-based research, there are caveats to consider:
-
Demographics: The study focused on 107 undergraduate students. The cognitive responses of older adults, children, or neurodivergent individuals may differ.
-
Controlled Setting: A 90-second guided task in a lab does not fully replicate the complexity of real-world environments where sounds are unpredictable and constant.
-
Short-term vs. Long-term: The study measures immediate shifts in imagery, not long-term mental health outcomes.
Practical Takeaways for Your Daily Life
What does this mean for the average person? It suggests that we can be more intentional about the “soundscapes” we inhabit:
-
For Creativity and Planning: If you are trying to brainstorm a new project or “see” a successful future, music—particularly tracks that evoke positive emotions—may help you visualize a more expansive and optimistic path.
-
For Meditation: If you find your meditation or relaxation exercises feeling “dull,” adding low-level ambient sound or music might actually help sharpen your mental focus more than total silence.
-
For Urban Living: Be aware that “background” noise isn’t just background. If you are feeling emotionally flat or stressed, the ambient traffic noise in your home or office might be subtly coloring your thoughts, even if you think you’ve “tuned it out.”
Ultimately, the research reminds us that our skin is a porous boundary. The world outside—its rhythms, its roars, and its melodies—constantly flows inward, shaping the very way we see the world behind our eyelids.
