Abstract
A measurement method is provided on an electrically conducting object. A first ultrasound wave is generated in the object by means of a first EMAT transmit transducer of a measurement arrangement. A first EMAT receive transducer of the measurement arrangement detects a first receive signal. The first receive signal comprises a first ultrasound signal resulting at least partially from the first ultrasound wave which has propagated through at least a part of the object, as well as a first electromagnetic interference signal. A second receive signal is also detected comprising a second electromagnetic interference signal by means of a first receive means of the measurement arrangement. The first receive signal and the second receive signal are processed jointly. At least the first receive signal is at least partially interference-suppressed.
