Abstract

In this study, we analyzed the kind of psychological effects that were caused by nonlinear, possibly chaotic vibrations as compared to regular vibrations. For this analysis, we produced a chaotic low-frequency electrical therapy device to generate chaotic vibrations. Using the device, we analyzed the direct effects of chaotic vibrations on the human body. In the experiments, we generated fully chaotic vibrations, intermittent chaotic vibrations, and periodic vibrations. To evaluate the effects of the vibrations on the human body, we used one of the subjective methods; a paired comparison method. We identified a rank-order scale by comparing pairs of two vibrations. The results indicate that complicated vibrations are more effective than periodic vibrations.
