Overview
This owl plush toy features directional microphones and a custom AI audio DSP. It tracks breathing rhythms to determine sleep stages and dynamically generates white noise and binaural beats optimized for the current sleep cycle, significantly extending deep sleep duration.
Audio Hardware
A custom codec board with dual MEMS microphones and a high-fidelity Class-D amplifier delivers 192kHz audio output. The enclosure acoustics were tuned using finite element analysis.
DSP Algorithm
Real-time respiratory rate extraction using adaptive filtering, feeding into a sleep stage classifier that adjusts audio generation parameters every 30 seconds.
Results
User studies demonstrated a 95% sleep tracking accuracy and a 23% increase in deep sleep duration compared to static sound machines.
