Abstract

In a method and a device for the detection of at least one structure-borne acoustic vibration in a component of an agricultural harvesting machine, a timer is used to determine a transit-time difference of a structure-borne acoustic vibration that is received by at least a first structure-borne sound sensor and at least a second structure-borne sound sensor and, based on the transit-time difference, a source of the structure-borne acoustic vibration is determined, thereby enabling the location of the pulses triggering the structure-borne acoustic vibration to be identified.
