DESCRIPTION
Exhibit 358 is a double siren consisting of a single axis driven by an electric motor through a leather belt. The axis activates a double counter of its rotations. On the wood base where the elements are fixed, there is also a rheostat intended to control the rotational velocity of the motor.
This instrument was apparently a part of experiments on interference effects in sound. For greater details, one should consult the bibliographic literature.
