Abstract
A system includes an acoustic attenuation interface disposed between a first acoustic transmission conduit and a second acoustic transmission conduit. An acoustic signal source acoustically coupled to the first acoustic transmission conduit generates an acoustic signal. An acoustic noise source acoustically coupled to the second acoustic transmission conduit generates an acoustic noise. A first sensor is configured to detect a first composite signal including the acoustic signal after transmission through at least a portion of the first acoustic transmission conduit and an attenuated acoustic noise. A second sensor is configured to detect a second composite signal including the acoustic signal after transmission through at least a portion of the first acoustic transmission conduit and attenuated by the acoustic attenuation interface and the acoustic noise. An acoustic signal processing system is configured to determine a noise-reduced signal from the first composite signal and the second composite signal.
