With the testing with 3D-NLS, the too investigator headphone carries, in which hearing only quiet sounds in different frequencies is, as a radio set (that looks for the correct frequency). 3D-NLS emits waves that the frequencies of the organs, that were determined from the pool of the comparison group, tested.

If the frequencies of the examined agree with the healthy comparison group, "synchronous" is, the appliance notes the similarity. With deviant frequency, the degree of the difference decides how strikingly the disturbance is noted. The checking of the whole body lasts on average with good approximately one half lesson, the more exact investigation at locked weak places can then last until two times. In the comparison to lengthy ambulance visits and compartment medical marathon's an almost unbelievable saving of time!
