The invention relates to a device and a method for the stimulation of neurons and muscle cells according to the principle of magnetic stimulation, wherein the invention generates substantially less acoustic sound emission for the same activation strength compared to the state of the art. This invention reduces the acoustic sound emission, usually a clicking sound, which is a safety risk in magnetic stimulation and causes undesired uncontrollable sensory-auditory brain stimulation, by increasing the frequency of a substantial portion of the spectrum of the pulse, preferably to or above the human hearing range. Furthermore, the invention relates to a quiet coil technology that reduces the conversion of electrical energy into mechanic-acoustic oscillations, whereby the transmission of the mechanic-acoustic oscillations to the surface is suppressed by elastic decoupling and the mechanic-acoustic energy is converted into heat by viscoelastic material deformation instead.
A device for generating a current pulse with a total duration of less than two milliseconds in at least one coil such that the at least one coil generates magnetic field pulses, which are configured to induce electrical currents in body tissue and evoke action potentials in neurons or myocytes, wherein the at least one coil is designed such that the generated magnetic field pulses can permeate the body tissue;
