(Schallunterbrecher nach Wundt)
Description: This apparatus apparently produces a pulse of a
certain tone.
The tone comes through a tube to a rotating disk. The disk has
15 precisely sized holes which can each be filled with a stopper.
The speed of the disk can be calibrated through a rotation
counter
which is mentioned but not shown. Seems sort of Rube Goldberg
to me. (Expanded caption Copyright 1998, Edward J. Haupt)
