Hartmann Tunning Fork C 256

Clinical Application

This two-pronged diagnostic tool is designed for basic auditory and vibratory assessments in ENT, audiology and general clinical settings. It is used to perform Rinne and Weber tests to help differentiate conductive from sensorineural hearing loss, and for quick bedside screening of vibratory sensation in peripheral neuropathy or cranial nerve evaluations. Its single-frequency, low‑pitch output aids detection of bone-conducted sound during preoperative screening, clinic evaluations, and intra-facility assessments.

Design & Configuration

The instrument’s two tines are tuned to a fixed C‑256 frequency, producing a low‑pitch vibration with a relatively long sustain. The stem handle provides a stable contact point for placement on the mastoid process or midline forehead during Weber testing and for controlled positioning on bony prominences when assessing vibratory sense. The single‑frequency design simplifies interpretation and reduces the need for multiple devices when a consistent reference tone is preferred.
