METHOD OF LOCATING EFFECT OF ACOUSTOELECTRIC CONVERSIONS IN EQUIPMENT AND DEVICE FOR REALISING SAID METHOD

摘要

FIELD: physics. ^ SUBSTANCE: before exposing the equipment under analysis to acoustic effect, using a theoretical or experimental directional pattern of the secondary magnetic component of the electromagnetic field of the acoustic radiator, the point with the least level is determined, where the said point has dimensions sufficient for placing the analysed equipment and taking signal measurements on its electromagnetic field. The analysed equipment is put in the determined place and the direction propagation of acoustic waves is shifted through reflection or re-reflection for effect on the analysed equipment and low-frequency signals are searched on the electromagnetic field in their frequency range. ^ EFFECT: low level of secondary radiation of the test signal on the magnetic component of the electromagnetic field from the acoustic radiator where the analysed equipment is located. ^ 2 cl, 2 dwg
