EEG-Guided Binaural Beat Audio to Reduce Performance-Related Stress and Improve Cognition

This study will test the efficacy and neurophysiologic mechanism of a novel EEG-guided binaural beat audio intervention for mitigating performance-related stress and enhancing cognition in musicians. The study is conducted at Texas Tech University (recruitment/screening/analysis) with neuroimaging and cognitive task data collection at the Texas Tech Neuroimaging Institute (TTNI).

Participants complete a single in-person visit (~3 hours) including consent and eligibility screening, task training, pre-intervention VAS and fMRI scanning, randomization to intervention or sham, a 30-minute audio session, post-intervention fMRI scanning, and post-intervention VAS.

The experimental audio intervention uses a proprietary algorithm with real-time EEG feedback from a single electrode over the left prefrontal cortex to dynamically adjust binaural beat frequencies during a 30-minute session delivered through headphones. The sham comparator uses non-binaural audio (music without interaural frequency differences) delivered identically. Participants and researchers conducting assessments are blinded to allocation.
