Abstract
The invention relates to supersonic control and is destined for the metrological ensuring of the acoustic - emissive instruments.The improvement of the devices diffusive characteristics for establishing the diffusive acoustic field is achieved by the fact, that the core 2 of the electromagnetic exciter, which affects the ferromagnetic specimen 1, is made in the form of a ring with a cut tangentially to the interior diameter of the core. By this the thickness of the ferromagnetic specimen is non less than 20 times exceeding the average of the polycrystalline material grain.
