LABORATORY STUDY OF THE EFFECT OF AN UNDERWATER ACOUSTIC FIELD ON AN ATMOSPHERIC ELECTRIC FIELD.
Abstract
A laboratory model was set up to study the effect of an underwater acoustic field on an atmospheric electric field. Measurable results, in satisfactory agreement with calculations, were obtained using a static field of 1,000 volts/meter, approximately 10 times that of the earth's field, and acoustic pressures in the range 100 to 1,000 dynes/square cm, at frequencies near 10KHz. In spite of the favorable laboratory conditions it was necessary to utilize a correlation technique to measure the low signals, which were in the range from 2 to 20 microvolts/meter. The electric field probe was essentially an antenna -- 2 cm in length. From the standpoint of instrumentation, the probe and associated detection equipment represent the development of an extremely sensitive electric field meter for low frequencies. (Author)
