The object of the invention is a method and device for characterizing the compaction result of a powder and monitoring the compaction act during the process. The sound emission produced by the process is measured by means of a sensor located in the vicinity of the process and transformed into a frequency spectrum in which the sound intensity is presented as a function of fre- quency. The intensity of the band relating to the sound emission arising from the compaction of the powder is recorded using compressive forces of differing magnitude, and the compaction result of the powder is obtained as a function of the intensity of the band relating to the sound emission arising from compaction. The method is useful both as a pilot method and as a process control method.
