HEARING SENSATIONS IN AMPLITUDE MODULATED RADIO FREQUENCY FIELDS.
Abstract
When the head is subjected to an amplitude modulated radio frequency field, a hearing sensation results. This sensation was investigated by holding a small circular metal probe close to the skull. The probe was then excited at a radio frequency of 3.5 megacycles. The audio frequency components of the field existing between the probe and the head produced the threshold electromechanical pressures necessary for hearing. These electromechanical pressures were computed and compared to the pressures on the skull which were necessary to produce bone conduction hearing. These pressure values fall within the same limits, and produce a similar characteristic threshold curve. This leaves little doubt that the investigated hearing phenomenon is caused by the bone conduction mechanism. (Author)
