Tuning Forks — Pattern and Clinical Use
In ENT, tuning forks distinguish conductive from sensorineural hearing loss through the Rinne and Weber tests, comparing air and bone conduction. In neurology, lower-frequency forks test vibration sense in peripheral neuropathy. The frequency determines the application: 512 Hz is the standard for hearing assessment, while 128 Hz is used for vibration testing.
Frequency accuracy is the entire specification. A fork that is out of calibration produces a misleading clinical result, so each is checked against a reference before the frequency is marked on the stem.
Tuning Forks Variants and Specifications
Standard frequencies and patterns.
| Frequency | Clinical application |
|---|---|
| 512 Hz | Standard for Rinne and Weber hearing tests |
| 256 Hz | Hearing assessment, longer decay |
| 128 Hz | Vibration sense; peripheral neuropathy |
| 1024 Hz | Higher-frequency hearing assessment |
| Weighted foot | Longer sustain for bone conduction |
| Clamped / damped pattern | Controlled decay for vibration testing |
Material, Finish and Quality Control
We forge Tuning forks from AISI 420 martensitic stainless. Every fork is checked against a frequency reference before its value is marked, since an out-of-calibration fork produces a misleading clinical result. Each batch passes Rockwell hardness testing, dimensional checks on frequency against reference, and visual inspection under our ISO 13485 system before passivation and final finishing. Mirror and satin finishes are both available — satin is usually specified where glare under operating lights is a concern.
Who Sources Tuning Forks From Surgical Star
Tuning forks sell to ENT, neurology, general practice and medical-education suppliers, and are commonly ordered as graduated sets covering both hearing and vibration frequencies.
OEM, Certification and Ordering
Every Tuning forks can be produced as a private-label line: your logo laser-marked on the stem, your catalog numbers, and your own printed packaging, manufactured from your drawings or a reference sample. Manufactured under an ISO 13485 quality system, CE-marked to EU MDR 2017/745 and covered by US FDA establishment registration. A certificate of conformity and an ASTM F899 material certificate for the exact steel grade ship with your order.
MOQs are low and new-brand friendly, and vary with pattern, finish and branding. Pricing is direct from the factory and tiered by volume. After you approve a branded pre-production sample, bulk production typically runs four to six weeks and ships worldwide DDP with HS codes handled. See how OEM & private label works →

Frequently Asked Questions
Which tuning fork is used for hearing tests?
512 Hz is the standard for Rinne and Weber testing. It balances audibility against sustain better than higher or lower frequencies.
What is a 128 Hz fork used for?
Testing vibration sense, typically in assessing peripheral neuropathy, rather than hearing.
How is frequency accuracy assured?
Each fork is checked against a reference before the frequency is marked on the stem, because an inaccurate fork gives a misleading result.
Can you manufacture these under our own brand?
Yes — full OEM and private label. We laser-mark your logo and catalog numbers, pack in your branded boxes, and work from your drawings, tech pack or a reference sample, with a pre-production sample approved before any bulk run.
