Abstract: A system is provided for detecting lung abnormalities in a subject. The system comprises a first sensor, for sensing a first acoustic signal generated by, or applied to, the subject and an arrangement of one or more second sensors for detecting a plurality of second acoustic signals from the lungs of the subject, wherein the second acoustic signals comprise attenuated versions of the first acoustic signal after passing through the lungs of the subject. The system further comprises a processor, wherein the processor is configured to determine a respective signal attenuation between the first acoustic signal and at least a subset of the plurality of second acoustic signals and process the signal attenuations thereby to detect a lung abnormality.
