The impact of music on cognitive execution has been broadly talked about, with varying conclusions in existing writing. Some studies claim music enhances concentration while others argue that it’s distracting. While this debate continues, this study intends to resolve the common discrepancies by exploring how different music genres affect study performance. An array of modern biometric devices including eye-tracking, facial expression analysis, and heart rate variability (HRV) provide objective real-time insights into how music affects concentration. This study goes beyond self-reported data using real-time biometrics for a more accurate examination of cognitive responsiveness to sound stimuli during study sessions. Whether background music contributes to improving cognitive performance is an area of ongoing controversy. The present study investigates the extent to which different classes of music affect study performance using biometric measures like eye-tracking, facial expression analysis, and heart rate variability (HRV). It identifies how Classical and Jazz types reliably improve focus and relaxation, while faster genres like Rock and Electronic are associated with extended distraction. Providing the data to optimize sound-related stimulation through predictive control creates very personalized learning environments. This work continues to innovate by introducing new research methods that enhance performance in learning and well-being through tailored auditory stimulation. Classical and jazz tend to increase attention, while fast-paced rock and electronic produce longer periods of inattentiveness. Some of the measures explored were focus duration, student extension, and heart rate variability, to offer an accurate objective real-time perspective on the sound-related stimuli applied to positive cognitive states. This analysis makes use of predictive modelling as a flexible framework for sound-related experience that could be personalized with a flexible contextually aware dynamic optimization. The results of this research provide a pedagogical opportunity for developing better instructional practices by aligning music genres to cognitive needs, with the potential for generating novel approaches to enhance educational performance and mental well-being.
