Infant cry classification integrated ANC system for infant incubators

The high noise level inside the infant incubator results in numerous adverse health effects for premature newborns and the active noise control (ANC) systems are developed to reduce the noise. This paper proposes an infant cry classification integrated ANC system for infant incubators. The developed system can dramatically reduce the harmful noise level, and the integrated infant cry detector and analyzer can monitor the infants´ physical conditions. The infant cry signals are picked up and detected by the same microphones used by the ANC system, the cry signal´s features are extracted and then recognized. The simulation and experiment results show that the cry recognition of specific infants yielded promising results.
