Acoustic tuning fork, made of aluminum, for neurological and ENT use, with a Y-shaped member. They resonate in a certain constant tone, striking it on a surface or with an object defines a vibration. During the oscillation of the percussion, sound frequencies are produced by both members and by the base. Each tuning fork during excitation produces a primary frequency at 128Hz, 256Hz or 512Hz.
Tuning forks dimensional weighted or unweighted with great accuracy.
