High noise in infant incubators results in numerous adverse health effects which have lifelong consequences for neonatal intensive care unit (NICU) graduates. This paper presents multi-channel hybrid active noise control (ANC) systems for infant incubators. A hybrid ANC algorithm is an integration of a feedforward algorithm (to cancel noise generated from sources outside the incubator) and a feedback algorithm (to reduce the predictable noise inside the incubator). Computer simulation and real-time experiment results show that the proposed hybrid algorithms are effective in cancelling both outside and inside noises of infant incubators in real NICU environment.
