Tunning Fork C 128 Alum.

Clinical Application

The C 128 tuning fork produces a 128 Hz tone useful for assessment of vibratory sensation in peripheral neuropathy screening and for complementary bedside bone‑conduction checks. It is commonly used in ENT and neurology clinics for quick, repeatable tests such as vibration sense on bony prominences and as an adjunct to bedside hearing screening (bone conduction). In perioperative and preoperative workflows it provides a simple, noninvasive method to document neurosensory baseline and follow-up changes.

Design & Configuration

Two parallel tines and a central stem provide a stable contact point for transmission of mechanical vibration to bone. The stem is used as the handle and placement interface—typically on the mastoid process, medial malleolus, or other bony landmarks—while the tines are struck to initiate vibration. The geometry and mass distribution determine resonance at 128 Hz, a frequency well suited to assessing vibratory perception rather than high‑pitch auditory acuity. Lightweight aluminum construction improves handling during repeated bedside tests and reduces user fatigue.

Instrument Specifications

• Model: C 128
• Frequency: 128 Hz
• Configuration: Two-pronged fork with stem (single-piece)
• Material: Aluminum alloy
• Intended use: Vibration sense testing and bone-conduction screening

Material & Construction

Manufactured from an aluminum alloy to provide a clear, low-frequency resonance and a light handpiece for repeated clinical use. Single-piece construction reduces joints and potential weak points; surface finish resists corrosion in routine clinical environments. The design supports repeated cleaning and handling typical for diagnostic instruments.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.

Brand Comparison

Comparable in form and function to equivalent instruments offered by major US medical suppliers.
