Perceptual Calibration and Passive Adaptation in Under-Pillow Audio Systems for Sleep and Care Environments

Abstract
This technical report outlines a perceptually grounded calibration model for under-pillow and near-field audio systems. The approach enables real-time tuning based on how sound is actually perceived through materials like foam and fabric. It supports sleep clarity, dementia care, and low-volume accessibility by using comparative signal analysis, passive interaction modelling, and non-diagnostic EQ shaping. All processing occurs locally, preserving privacy while adapting to listener context. Though focused on sleep environments, the same principles apply to wearable, embedded, or surface-coupled audio systems.
