Hartmann Tuning Fork with Weights, Stainless Steel, 128 Hz

The Hartmann Tuning Fork with Weights (Stainless Steel, 128 Hz) is a precision diagnostic instrument engineered for quantitative audiological testing and neurological sensory evaluations. Calibrated specifically to a fundamental low frequency of 128 Hz, this instrument is indispensable in otolaryngology and neurology for conducting Rinne and Weber hearing tests to differentiate between conductive and sensorineural hearing loss, as well as assessing pallesthesia (vibrational perception threshold) in diabetic neuropathy screenings. Constructed from high-grade stainless steel with weighted prongs, it delivers a clean, prolonged acoustic resonance with minimal overtone interference, ensuring highly accurate acoustic and somatosensory feedback.

Features:

• Calibrated 128 Hz Resonance: Precision-tuned fundamental frequency optimized for otological hearing tests (Rinne/Weber) and mapping bone-conduction thresholds across bony prominences.
• Integrated Damper Weights: Fitted with fixed  weights at the distal ends of the prongs to dampen unwanted higher-order overtones (harmonics) and extend total vibration decay time.
• Surgical-Grade Stainless Steel Construction: Manufactured from non-magnetic, corrosion-resistant stainless steel, offering superior structural stability and thermal durability compared to aluminum alternatives.
• Hygienic & Autoclavable: Fully resistant to liquid disinfectants, enzymatic detergents, and standard steam autoclave sterilization protocols without compromising acoustic tuning.
