Hartmann Tunning Fork C 256

Clinical Application

This diagnostic instrument is used for rapid bedside assessment of hearing and bone conduction. The C 256 tuning fork supports Weber and Rinne maneuvers to help differentiate conductive from sensorineural hearing loss and to localize lateralization of sound. It is commonly used in otology clinics, primary care and neurology settings for screening and follow-up, and as an adjunct to audiometric testing when immediate, point-of-care information is needed.

Design & Configuration

The two-pronged U-shaped design concentrates vibratory energy into a clear, sustained tone when the tines are struck. The stem/handle provides a stable contact point for placement on the forehead, vertex or mastoid process to transmit bone-conducted sound. The C 256 designation corresponds to the pitch produced (C, 256 Hz), a reliable frequency for auditory testing that balances audibility and duration of vibration for clinical maneuvers.
