Development and applications of active noise control system for infant incubators

This paper presents the application of audio-integrated active noise control (ANC) system for infant incubators. The integrated ANC algorithm is developed to reduce harmful noise and also play healthy with intrauterine sounds inside the incubators. Real-time experiments are conducted to evaluate the performance of integrated system using a Giraffe incubator from GE Healthcare. The noise reduction achieved by ANC systems at uniformly-distributed three-dimensional locations inside the incubator is tabled and presented graphically.
