description A method for optimizing percussive drilling, especially rock drilling, in which method the operation of the drilling device is adjusted for a desired drilling result to be obtained. According to the invention, a stress wave created in a drill rod as a result of a stroke is measured and the drilling device is adjusted on the basis of the measured stress wave. The adjusting is carried out e.g. by means of the damping rate or the spectrum of the measured stress wave or the shape of the stress wave and/or the energy fed by the different portions thereof.
