Abstract

This paper presents a pioneering healthcare application of active noise control (ANC)-the intrauterine acoustics embedded ANC system for reducing noise levels inside infant incubators in neonatal intensive care units. Incorporating intrauterine audio with incubators has proven medical benefits. However it is necessary to develop an ANC system to optimize the benefits of the integration. A computer model utilizing measured transfer functions from an experimental setup is developed for simulations using real medical equipment noise. An average cancellation of 16 dB was observed. The simulation of the audio integrated ANC system produced optimal results and the system was validated to be robust and efficient.
