Inter-subject EEG correlations reveal shared responses to music's arousal and acoustic properties
Synchronized brain activity (EEG) across individuals listening to music can be correlated with both subjective arousal levels and objective acoustic features of the music itself.
Frontiers in Human Neuroscience · 2023
Key Findings
- 01Higher inter-subject correlation (ISC) in EEG signals was observed for music pieces that were highly preferred by a large population, suggesting a link between shared brain activity and broad music engagement.
- 02Variations in the first three principal components of EEG differed significantly across music pieces, indicating that specific musical characteristics and emotional responses influence synchronized brain activity.
Application
Design takeaway
Prioritize music and sound design that elicits consistent, positive neurophysiological responses across a diverse audience by considering both objective acoustic properties and subjective arousal potential.
How to apply
When designing the soundscape for a product or environment, consider testing music samples with diverse user groups to measure not only subjective feedback but also potential for synchronized physiological responses.
Project actions
- 01When designing an auditory experience, consider how different sound elements might affect a user's arousal and engagement.
- 02Research existing music or sound libraries that are known to be broadly appealing and analyze their acoustic properties.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a robust neuroscientific method (ISC) to investigate subjective experiences.
- +Employs popular music as a proxy for broad audience preference.
Limitations
It's difficult to measure 'shared brain activity' directly in a typical design project without specialized equipment. Generalizing findings from one music genre to another can be problematic.
Reliability & validity
Reliability could be improved by using a larger and more diverse sample size and a wider range of music genres. Validity is supported by the use of established neuroimaging techniques and correlation analysis.
Think critically
How might individual cultural backgrounds or prior musical experiences influence the 'shared' brain responses observed in this study?
Design Principles
"Auditory elements should be designed to evoke predictable and shared neurological responses, aligning with a target audience's inherent preferences and arousal thresholds."
This research offers a neuroscientific basis for understanding why certain musical elements resonate with a broad audience. By identifying patterns in shared brain responses, designers can gain insights into creating more engaging and universally appealing auditory experiences, whether in product design, interactive installations, or media.
What This Means for Your Design
This study shows that when many people listen to the same song, their brains often react in similar ways, especially if they like the song. This shared brain activity is connected to how exciting the music is and its sound.

Paragraph starter
Research indicates that inter-subject correlations in brain activity, such as EEG, can reflect shared responses to music, linking subjective arousal and objective acoustic features to broad user engagement. This suggests that auditory design choices can be informed by understanding how specific sonic characteristics elicit predictable neurological responses across a population, potentially enhancing user experience and product appeal.
