Tunning Fork a1 440

Clinical Application

This diagnostic tuning fork is intended for clinical assessment of auditory and somatosensory function. The 440 Hz pitch (A4) provides a stable, easily recognizable tone useful as a pitch reference in audiology and for basic Weber and Rinne screening tests. It can also serve as an adjunctive screening tool in neurology and primary care for assessing vibration perception and in orthopedics for preliminary evaluation of localized bone pain related to suspected occult fractures. As with all tuning-fork testing, findings should be interpreted alongside history, physical exam, and definitive diagnostic studies.

Design & Configuration

The two-pronged fork geometry concentrates vibratory energy in the tines while the stem transmits those vibrations to the clinician's hand and, when applied, to patient contact sites. The A1 440 frequency produces a clear, sustained tone that is easy to identify by ear for pitch-based tasks. The simple stem handle allows controlled placement on bony prominences (mastoid process for auditory testing; distal phalanges or bony prominences for vibration testing). Because different clinical tests favor different frequencies (for example, 128 Hz is commonly used for peripheral vibration testing and ~512 Hz for detailed hearing conduction testing), the 440 Hz instrument is particularly practical when a musical pitch reference or basic auditory screening is desired.

Material & Construction

Constructed from corrosion-resistant stainless steel to provide consistent vibratory response and long-term durability. The forged two-prong design maintains pitch stability and resists deformation with routine clinical use. Designed for repeated cleaning and sterilization according to facility protocols, enabling reusable use in outpatient, clinic, and inpatient settings.

Quality & Compliance

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