Beschreibung
Zusammenfassung:	The invention refers to technique of control-test processes and can be used in shop conditions at testing domestic electric motors, stabilizers, transformers, etc. during their mass production. The technical result of the invention is simplification of the device used at mass production. The noise-attenuating plate is entered into one of channels of the device before a microphone which creates a difference of magnitude of the measured noise signals, proportional to the noise level, made by an article. 1 figs.
