1. A device for capturing vibrations produced by an object, the device comprising: a first sensor in contact with a surface of the object; a second sensor spaced apart from the object and the first sensor and located relative to the object; and a fixation element for fixing the device to the object, wherein the first sensor is placed in contact with the object by the fixation element and wherein the second sensor is located relative to the object by the fixation element, wherein the first sensor is a piezoelectric sensor element which captures vibration in the object at the fixation element, and wherein the second sensor is a coil sensor.
