| 摘要 |
The present invention relates to a device and a method for the stimulation of nerve and muscle cells according to the principle of magnetic stimulation, wherein the invention has a significantly reduced sound emission for the same stimulus intensity when compared to the prior art. The sound emission in the form of a click noise, which, in the magnetic stimulation, determines on the one hand an important safety risk and on the other hand causes an undesired, uncontrollable sensory-auditory brain stimulation is reduced in the present invention by increasing the frequency of a substantial portion of the spectrum of the pulse, preferably up to or beyond the human hearing range. The invention further relates to a quieter coil technology which reduces the conversion of electrical energy into mechanical-acoustic oscillations, prevents the transfer of said oscillations to the surface by resilient decoupling and instead converts the mechanical-acoustic energy via viscoelastic deformation of the material into heat. |
