The 512 Hz frequency is the clinical standard for the Rinne and Weber tests, the two most widely used bedside auditory assessments for differentiating conductive and sensorineural hearing loss. The unweighted design allows the tines to vibrate freely at the pure 512 Hz frequency without the dampening effect of added weights, producing a clear, consistent tone ideal for auditory testing. Clinical grade construction ensures the frequency accuracy and durability required for reliable, repeatable professional use.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1443\/4772\/products\/baseline-nerve-sensory-evaluator-access-default-title-baseline-clinical-grade-tuning-fork-512-hz-unweighted-23631682502710.jpg?v=1788637186\" alt=\"Baseline clinical grade tuning fork 512 Hz unweighted for Rinne and Weber auditory screening tests and upper-extremity sensory assessment SKU 10056E\" style=\"max-width:100%;height:auto;\"\u003e\n\n\u003ch2\u003eBaseline Clinical Grade Tuning Fork 512 Hz, Key Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e512 Hz frequency, the clinical standard for Rinne and Weber auditory screening tests\u003c\/li\u003e\n\u003cli\u003eUnweighted tines for pure, undampened 512 Hz vibration ideal for auditory assessment\u003c\/li\u003e\n\u003cli\u003eClinical grade construction, superior precision and frequency accuracy for professional use\u003c\/li\u003e\n\u003cli\u003eStandard instrument for differentiating conductive and sensorineural hearing loss at bedside\u003c\/li\u003e\n\u003cli\u003eAlso suitable for upper-extremity vibratory sensation and sensory nerve assessment\u003c\/li\u003e\n\u003cli\u003ePreferred for professional clinical, diagnostic, and ENT settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSKU: 10056E\u003c\/li\u003e\n\u003cli\u003eUPC: 19213010867\u003c\/li\u003e\n\u003cli\u003eBrand: Baseline\u003c\/li\u003e\n\u003cli\u003eFrequency: 512 Hz (cycles per second)\u003c\/li\u003e\n\u003cli\u003eGrade: Clinical\u003c\/li\u003e\n\u003cli\u003eWeights: No (unweighted tines)\u003c\/li\u003e\n\u003cli\u003eUse: Auditory screening, Rinne and Weber tests, upper-extremity sensory assessment\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: China\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eIdeal For\u003c\/h2\u003e\n\u003cp\u003eThe Baseline Clinical Grade Tuning Fork 512 Hz Unweighted is well suited for physicians, nurse practitioners, and physician assistants who perform bedside auditory assessments including the Rinne and Weber tests to screen for and differentiate conductive versus sensorineural hearing loss and need the 512 Hz unweighted fork as the standard instrument for these examinations. Otolaryngologists and ENT specialists who use tuning forks as a quick, reliable bedside complement to formal audiometric testing will find the clinical grade construction appropriate for the precision required in professional ENT practice. Occupational therapists and physical therapists performing upper-extremity sensory nerve assessments who use 512 Hz for fine touch and vibratory sensation evaluation of the hands and forearms will find the unweighted design produces a clear, consistent stimulus for sensory testing. Nursing and medical education programs that teach bedside auditory assessment techniques will find the clinical grade instrument appropriate for both instructional and clinical use where frequency accuracy matters.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the Rinne and Weber tests?\u003c\/strong\u003e\u003cbr\u003eThe Rinne test compares air conduction to bone conduction hearing by placing the vibrating fork base on the mastoid bone and then holding it near the ear canal, asking the patient which is louder. The Weber test places the vibrating fork base on the center of the forehead and asks the patient whether the sound lateralizes to one side. Together, these tests help differentiate conductive hearing loss from sensorineural hearing loss. The 512 Hz fork is the standard frequency for both tests.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is the 512 Hz fork unweighted for auditory testing?\u003c\/strong\u003e\u003cbr\u003eWeights on tuning fork tines extend vibration duration but also slightly alter the vibration characteristics and can introduce overtones that affect the purity of the tone. For auditory testing where the patient is listening to the sound rather than feeling the vibration, an unweighted fork produces a cleaner, purer tone that is easier for the patient to perceive and report accurately. Weighted forks are preferred for vibratory sensation testing where sustained vibration duration is more important than tonal purity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between clinical grade and student grade tuning forks?\u003c\/strong\u003e\u003cbr\u003eClinical grade tuning forks are manufactured to tighter tolerances with higher-quality materials, resulting in superior frequency accuracy, more consistent vibration characteristics, and greater durability under repeated clinical use. For auditory screening applications where precise frequency is important to test validity, clinical grade construction is the preferred choice for professional practice.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I care for a clinical grade tuning fork?\u003c\/strong\u003e\u003cbr\u003eStore the tuning fork in a protective case or pouch to prevent damage to the tines. Avoid dropping the fork or striking it against hard surfaces, as this can alter the vibration frequency or damage the tines. Clean with a mild disinfectant wipe between patients. Do not autoclave or expose to high heat, as this can affect the metal's temper and alter the fork's frequency accuracy.\u003c\/p\u003e","brand":"Baseline","offers":[{"title":"Default Title","offer_id":40388468867126,"sku":"10056E","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1443\/4772\/products\/baseline-nerve-sensory-evaluator-access-default-title-baseline-clinical-grade-tuning-fork-512-hz-unweighted-23631682502710.jpg?v=1788637186","url":"https:\/\/www.precisionlabworks.com\/en-ca\/products\/baseline-clinical-grade-tuning-fork-512-hz-unweighted","provider":"Precision Lab Works","version":"1.0","type":"link"}
