1. A system comprising:
an acoustic attenuation interface disposed between a first acoustic transmission conduit and a second acoustic transmission conduit, wherein the acoustic attenuation interface comprises a lubrication assembly of a drive shaft;
an acoustic signal source that generates an acoustic signal, acoustically coupled to the first acoustic transmission conduit;
an acoustic noise source that generates an acoustic noise, acoustically coupled to the second acoustic transmission conduit;
a first sensor coupled to the first acoustic transmission conduit, wherein the first sensor is configured to detect a first composite signal comprising the acoustic signal after transmission through at least a portion of the first acoustic transmission conduit and an attenuated acoustic noise comprising the acoustic noise after transmission through at least a portion of the second acoustic transmission conduit and attenuated by the acoustic attenuation interface;
a second sensor coupled to the second acoustic transmission conduit, wherein the second sensor is configured to detect a second composite signal comprising 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 after transmission through at least a portion of the second acoustic transmission conduit; and
an acoustic signal processing system, in communication with the first sensor and the second sensor, configured to determine a noise-reduced signal from the first composite signal and the second composite signal.
