| Abstract |
BioTune is a non-invasive biofeedback device that helps individuals manage stress through real-time adaptive sound therapy. By continuously monitoring heart rate variability and skin conductance, BioTune detects physiological arousal and automatically layers calming nature sounds to guide users toward self-regulation. This project evaluates whether BioTune's adaptive response produces greater parasympathetic activation and faster stress recovery compared to standard non-adaptive calming music. |
