Rydel Seiffer, Lucae and Hartmann Tuning Forks
Example of Rydel Seiffer tuning fork,
c 128/C 64 Hz with damper and
plastic foot
Dear Customer, thank you for choosing a KaWe product. Our products
are known for their high quality and longevity. This KaWe product
meets EC Standards 93/42/EWG (standards for medical products).
Please read this User's Manual thoroughly and care-
fully before attempting to use this product and heed the
given care instructions.
Use: These tuning forks are only to be used by authorized, trained
personnel. The tuning forks create sound that is then conducted
through the air and bone. The tuning forks are only to be placed on
healthy skin. The plastic foot or end of the vibrating fork is placed on to
the part of the body that is being examined. These are primarily spots
on the extremities where the joints are not covered by muscle or fatty
tissue. In order to ensure long-term monitoring, the results of each
inspected area should each be compared with one another over time.
For this purpose, the response of the patient is needed in order to de-
termine at which point of the fading process of the fork's oscillation
the patient no longer feels the vibration.
Using the Rydel Seiffer tuning fork: The Rydel Seiffer tuning fork
produces two different frequencies: with attached dampers, the tone
C = 64 Hz (as printed on the dampers) and the tone C = 128 Hz (as
printed on the tuning fork itself). If the dampers are attached, the bot-
tom edge of the dampers must be set to the calibration mark on the
tuning fork tines whereby the label "c 64" on the dampers and the la-
bel "c 128" on the tuning fork (front side) as well as the calibration
mark are to always be facing the observer. The dampers can be loos-
ened and/or tightened with the knurled screws. Please tighten these
knurled screws securely.
There are scales on the dampers on the back side of the tuning fork. By
observing these scales, the vibration intensity of the tuning fork can
be started with the same magnitude of vibration each time the pa-
tient is examined.

This takes place as follows:
• The tuning fork with attached dampers (thus/so the tone C = 64
Hz) is struck on the ball of the hand. The initial vibration of the tun-
ing fork tines is so strong that both triangles appear to be com-
pletely blurred. After a few seconds, depending on the intensity
with which the tuning fork was struck, the triangles will begin to
appear on the base line and will grow slowly, that is with slowly
diminishing vibration intensity to the first, second, third etc. tick
mark on the scale. This means that the examination can be begun
on a particular tick mark on the scale, whereby, depending on the
light quality and or visibility, the black or white triangle can be used.
It is well-known that the onset of the deterioration of the nervous
system can be detected through a decrease in vibration perception. A
replication of the magnitude of these vibrations is a prerequisite for
the practical application of this diagnosis.
Using the Lucae tuning fork: The Lucae tuning fork produces 7
different frequencies from c 128 to b 240. The exact frequencies are
given in the following table.
Frequencies in Hz
The frequency is changed by sliding the weights on the tines of the
fork. The weights can be easily moved with the hand. When changing
the tone it is absolutely imperative that the spring in the weight slides
securely into the slot on the tuning fork. Both weights must always be
set at the same height. It is not possible to create overtones by setting
