magnetic stimulation system to the reduction in acoustic emissions by avoiding the human audible range and utilizing pycho-acoustic phenomena

摘要

Device for generating a short current pulses with a total duration of less than a millisecond in at least one coil, so that the at least one coil magnetic field pulses with a magnetic flux density of from 0.1 to 10 tesla is generated, which, according to the principle of electromagnetic induction in the bodily tissue of electric currents, which cause at least one potential of action by stimulation of nerve cells and / or muscle cells triggering, wherein the at least one coil is configured in such a way that a magnetic field produced by it can pass through the body tissue; wherein the device includes at least a capacitor for storing a part or of the entire for the magnetic field pulses, wherein the energy required by the magnetic field of the coil caused, for example by electrical stimulation currents at least one tenth and a maximum of the ten times the irritation of the cells for stimulating currents are required; characterized in that the device for reduction of the on account of the current pulse of the coil and / or at least one electrical supply cables to the at least one coil emitted acoustic sound is designed in such a way that at least one electrical conductor of the at least one coil and / or of the at least one electrical feed cable by means of an embedding in a mechanically rigid polymer and / or a mechanically rigid plastic and / or a mechanically rigid composite material and / or a mechanically rigid ceramic and / or a mechanically rigid glass forms a rigid unit; and wherein less than a quarter of the energy of the electrical current pulse in the frequency range of 500 hz to 18 khz.
