Medical Tuning Fork Set — 4 Frequencies: 128Hz, 256Hz, 512Hz, 1024Hz

Tuning forks are pure acoustic instruments — they produce a nearly perfect sinusoidal tone at a precisely defined frequency, making them simultaneously the physicist's vibration standard and the clinician's neurological test tool.

The 128Hz fork tests vibration sense in peripheral neuropathy assessment; 256Hz is the medical standard for bone conduction hearing (Rinne and Weber tests); 512Hz tests air-conduction hearing and pitch matching; 1024Hz is used in audiometry calibration. Strike on the heel of your hand — the fork rings at its resonant frequency for 5–10 seconds, decaying as energy converts to acoustic wave and heat.

• 4 forks: 128Hz, 256Hz, 512Hz, 1024Hz — aluminum alloy
• Frequency accuracy ±1Hz; weighted foot for sustained ring duration
• Non-magnetic — safe in all clinical environments
• Stored in vinyl roll pouch; each fork frequency-labelled
