Edge Computing based Multi-channel Active Noise Control System with Virtual-sensing Function for ICU Patient Bed
2021 IEEE International Conference on Systems, Man, and Cybernetics (SMC)（2021）
摘要
The purpose of this research is to reduce high noise level for patients in intensive care unit (ICU) environments. The study has designed and developed the auxiliary filter based virtual sensing (AF-VS) active noise control (ANC) system. Filtered x least mean square (FxLMS) algorithm is used to reduce the interfering noise around ICU patients’ heads. A multi-channel feedforward AF-VS ANC algorithm...
