512 Hz tuning fork is a medical diagnostic instrument commonly used to assess hearing function and nerve sensation (vibration sense).
What it is used for
Hearing tests (Rinne & Weber tests)
Helps determine conductive vs sensorineural hearing loss
512 Hz is preferred because it is:
Mid-range frequency (close to human speech perception)
Produces a clear vibration without excessive bone or air conduction bias
Neurological examination
Tests vibration sense in conditions affecting peripheral nerves
Common in screening for:
Related neuropathy
Spinal cord disorders
Vitamin B12 deficiency
