Baseline Student Grade Tuning Fork, 256 Hz, Weighted

The Baseline Student Grade Tuning Fork (256 Hz, Weighted) is a versatile clinical instrument used for auditory screening and vibratory sensation assessment. The 256 Hz frequency occupies a middle position in the clinical tuning fork range — lower than the 512 Hz fork used for standard Rinne and Weber auditory tests, and higher than the 128 Hz fork used for lower-extremity vibratory sensation testing. It is commonly used for bone conduction testing, general sensory nerve assessment, and in educational settings where a mid-range frequency fork is needed. The weighted tines extend the duration of vibration after striking, providing a sustained, consistent stimulus for assessment. Student grade construction offers durable and cost-effective performance for educational and clinical use.

Ideal For

Nursing, medical, and allied health students who need a mid-range tuning fork for clinical skills training will find the 256 Hz weighted fork appropriate for learning bone conduction testing techniques and general sensory assessment protocols taught in clinical education programs. Physicians and nurse practitioners who perform bedside auditory and neurological assessments and prefer a 256 Hz fork for bone conduction testing will find this student grade instrument a cost-effective option for clinical use. Physical therapists and occupational therapists performing peripheral sensory evaluations who work across a range of patient populations and assessment needs will find the 256 Hz frequency a versatile mid-range option. Clinics and educational programs stocking tuning forks for student or staff use will find the student grade construction a cost-effective option for high-volume or shared use.

Frequently Asked Questions

How does the 256 Hz fork differ from the 128 Hz and 512 Hz forks?
The 128 Hz fork is the standard for lower-extremity vibratory sensation testing — its low frequency produces a vibration easily felt through bone and tissue, making it ideal for sensory nerve assessment in the feet and ankles. The 512 Hz fork is the standard for auditory screening (Rinne and Weber tests) and upper-extremity sensory assessment. The 256 Hz fork sits between the two and is commonly used for bone conduction testing and general sensory assessment where a mid-range frequency is preferred. Some clinicians use the 256 Hz fork for Rinne and Weber tests as an alternative to 512 Hz.

What do the weights on the tines do?
Weights attached to the tines lower the effective vibration frequency slightly and significantly extend the duration of vibration after striking. This gives the clinician more time to apply the fork to the patient and complete the assessment before the vibration fades. The weighted design is preferred for sensory testing where a sustained, consistent stimulus is needed.

How do I use a tuning fork for bone conduction testing?
Strike the weighted tines against a firm but yielding surface — such as the heel of your hand or a rubber pad — to set the fork vibrating. Place the base of the vibrating fork on a bony prominence such as the mastoid bone, forehead, or sternum depending on the test being performed. The patient indicates whether and where they hear or feel the vibration. Consult a clinical assessment reference for full test interpretation guidance.

How do I care for a tuning fork?
Store 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.
