Field minimizing arrangement with acoustic signal generators, e.g. loudspeakers

摘要

The arrangement includes two almost identical acoustic signal generators, which are slightly space from a measurement receiver sensitive to alternating electric or magnetic fields. The arrangement includes two acoustic signal generators at a small distance from a measurement receiver sensitive to alternating magnetic or electric fields. The signal generators are arranged close to each other, with approximately parallel axes, but not necessarily side by side. The positive pole of one signal generator, provided by the manufacturer, is connected to the positive pole of the other, almost identical, signal generator, whereby it becomes its actual negative pole. The direction of the largest sensitivity of the measurement receiver is preferably positioned orthogonal to a local field line course.
