Abstract
In an intensive care unit (ICU), there are different types noises. For example, patients suffer from the noise which is made by doctors' or nurses' activities and devices of ICU can cause some problem too, like stress and losing ability of hearing. In this paper, we propose to use active noise control (ANC) systems to reduce the high noise level for intensive care unit (ICU) residents. This paper proposed a multiple channel feedforward virtual sensing ANC system. Instead of achieve maximum noise cancellation at the error microphone locations, this technique can move quiet zone to the virtual sensor locations which are hard to place actual physical sensors. Sinusoidal noise, white noise and recorded ICU noise have been used as primary noise sources to validate the system's noise cancellation performance. Computer simulation results prove that the proposed system can reduce ambient noise level around patient's ears.
