Lucae Tunning Fork C 256

Clinical Application

This diagnostic tuning fork is used in otology, audiology and neurology to evaluate bone conduction and vibratory sensation. When struck and placed on the mastoid process or forehead it supports Weber and Rinne assessments to help differentiate conductive from sensorineural hearing loss. The lower C256 frequency is also commonly employed for testing vibratory threshold at bony prominences when screening for peripheral neuropathy or monitoring sensory function over time.

Design & Configuration

The two-tine design with a central stem transfers a stable, sustained vibration to bone, enabling clear perception of bone-conducted sound and tactile vibration. The stem/handle offers a single-handed grip for controlled placement on small targets (mastoid, forehead, malleolus, tibia) and for repeatable strikes. The instrument's nominal 256 Hz pitch produces a lower-frequency vibration that is particularly useful for assessing vibratory sense at distal sites.
