Physiologist Ernst Heinrich Weber (1795–1878) of Leipzig first recorded this in experiment in 1825. The Weber experiment serves to identify a laterality of the sense of hearing with the use of a tuning fork. This tuning fork method for testing sensibility, which was first used in 1903, is still considered to be the most dependable and safe even today. Without the dampers, the instrument vibrates at a frequency of 128 Hz and is used for simple hearing and bone conductivity tests.

The screwed-on plastic foot allows for a gentle transfer of the vibrations from the tuning fork to the patient. It is in this configuration that the tuning fork is used in vibration examinations. Reference marks for exact calibration of the original KaWe tuning fork can be found on the back side of the fork tines.

With the screwed-on dampers, the fork vibrates at 64 Hz. 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. 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.

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