Tuning Forks –
RYDEL-SEIFFER c=128/C=64Hz
Indispensable for determination of complete patient status

Medicinal tuning forks are permanently associated with names such as Weber and Rinne or Rydel Seiffer. Every carefully-done, complete physical examination of a patient involves the use of a tuning fork.

The graduated tuning fork developed by Rydel Seiffer c 128 Hz/C 64 Hz is a standard in the field of neurology and is also probably the most well-known neurological tuning fork. This calibrated tuning fork has removable dampers with a 1/8 scale graduation and is used to identify a loss of the sense of vibrations, and is used to diagnose polyneuritis which can occur e.g. along with diabetes mellitus. With the screwed-on dampers, the fork vibrates at 64 Hz. Reference marks for exact calibration of the original KaWe tuning fork can be found on the back side of the fork tines. It is in this configuration that the tuning fork is used in vibration examinations. The screwed-on plastic foot allows for a gentle transfer of the vibrations from the tuning fork to the patient. Without the dampers, the instrument vibrates at a frequency of 128 Hz and is used for simple hearing and bone conductivity tests. This tuning fork method for testing aesthesia, which was first used in 1903 to test, is still considered the most dependable and safe even today.

The Weber experiment serves to identify a laterality of the sense of hearing with the use of a tuning fork. Physiologist Ernst Heinrich Weber (1795–1878) of Leipzig first recorded this in experiment in 1825. Hildesheimer psychologist Heinrich Rinne (1819–1868) amended the test in 1855. Whereas the Weber test serves to compare the sound perception of each ear by means of bone transmition, the Rinne test compares air and bone transmition. Both tests together form a standard test for the examination of hearing damage as well as of the eighth cranial nerve.

Stethoscope, reflex hammer, diagnostic lamp and tuning fork – only with the use of these three instruments together, can the complete status of the patient be determined. They are therefore, all indispensable pieces of equipment for every doctor. Practicing doctors from almost every specialty field are however, not the only ones that use this valuable diagnostic instrument. Speech therapists and alternative medicine practitioners also value classic tuning forks as important instruments in their daily work activity.

KaWe sets high standards for its tuning fork production. Our tuning forks are not manufactured in series, but each one is manually tuned several times ensuring that it is guaranteed to hold its pitch. Each original KaWe tuning fork is labelled according to its tone and corresponding frequency. The specially-selected materials permanently guarantee long tone stability, long-lasting vibration and the sound purity that you are accustomed to. This small classic is simultaneously a precision instrument for your doctoral practice.
