Design and Implementation of an IoT Acoustic-Controlled Pillow for Sleep Health Monitoring

This letter introduces an Internet of Things (IoT) acoustic-controlled pillow to reduce environmental noise, monitor snoring, and mitigate insomnia symptoms for enhancing sleep quality. The pillow offers a comprehensive sleep solution by integrating digital hardware active noise control (ANC) technology with an IoT snore tracker. The acoustic control component employs cost-effective digital circuits tailored for effective noise cancellation and music playback functionality, unlike systems using digital signal processors or field-programmable gate arrays. The IoT snore tracker component utilizes mel-frequency cepstral coefficients for precise snore detection, further supported by the capability to upload audio data for further analysis. This dual-functional design not only addresses environmental noise and mitigates insomnia symptoms effectively but also actively monitors snore-related disturbances. Comparative analysis underscores its affordability and practicality, positioning it as a favorable choice for consumers in noisy environments to aid relaxation and sleep induction.
