摘要

device for determining the critical frequency of the fusion of light, sound and schwingungssignalen, characterised by the fact that the units for the production of light, sound and vibrationssignalen merged in a setting that the possibility of a separate. r co signalgabe on the left and right eyes.the left and right ear and right and left hand to ensure that the electric impulses with continuously adjustable folgefrequenz are created that the pulse length (ms) in the range of 1% to 99% of the impulswiederholun current pulse length, and the regulation of impulspause brightness, volume and great swing allows.
