Koenig Tuning Fork

Description

Koenig Tuning Fork

The Koenig tuning fork is a low pitched diagnostic fork. The manufacturer’s catalogue lists this pattern at 109 Hz, the note a. It also carries clamps on the prongs plus a flat foot, so you can hold it against bone as well as next to the ear.

Why a low pitch

Low frequencies are easier to feel than to hear. For that reason, clinicians often use a fork in this range to check vibration sense over bony points of the feet and hands. In addition, the foot lets you press it firmly on the mastoid or the forehead when you compare bone and air conduction.

Choosing a Koenig tuning fork

Choose this fork when you want a slow, strong vibration that lasts. By contrast, a Hartmann fork at 512 Hz suits hearing tests such as Rinne and Weber, while a Rydel-Seiffer fork adds a graded scale for scoring vibration. Many practices therefore keep one low and one mid pitch fork.

Care

Strike the Koenig fork on a rubber pad or your knee rather than a table edge, because a hard knock can shift the pitch. Then wipe the prongs and foot between patients, and store the fork in its case.
