Rydel-Seiffer tuning fork

Rydel-Seiffer tuning fork

Rydel-Seiffer tuning fork

The original design Rydel Seiffer 64/128 Hz graduated tuning fork. End weights convert the tuning fork from 128 to 64 Hz (removable version). The weights have been scaled allowing reliable quantitative vibratory testing. As the intensity of the vibration starts to diminish the two triangles move closer together again and their point of intersection moves slowly upwards. The intensity at which the patient no longer detects the vibration is read as the number adjacent to the intersection of the triangles. Instructional sheet, references and values for normal healthy controls are included [JNNP 1998;65(5):743-7]. Manufactured in Germany to the original specification for over 90 yrs. Each tuning fork check for accuracy. Do not be fooled by imitations. For reference list >click here<
