1. A system, comprising:
- a controller configured to receive noise signals acquired by at least two knock sensors of a plurality of knock sensors coupled to a reciprocating device at different locations associated with different cylinders of the reciprocating device, each noise signal representing a noise signature of the reciprocating device detected at a respective knock sensor, to detect a presence of a coincident noise based at least on the received noise signals, and to determine, when the coincident noise is present, a location of the coincident noise within the reciprocating device based at least on the received noise signals.

Abstract
A system includes a controller configured to receive noise signals acquired by at least two knock sensors of a plurality of knock sensors coupled to a reciprocating device. Each noise signal represents a noise signature of the reciprocating device detected at a respective knock sensor. The controller is also configured to determine a location of a coincident noise within the reciprocating device based at least on the received noise signals.
