Alterations in Adenylate Kinase Activity in Human PBMCs after In Vitro Exposure to Electromagnetic Field: Comparison between Extremely Low Frequency Electromagnetic Field (ELF) and Therapeutic Application of a Musically Modulated Electromagnetic Field (TAMMEF)

Figure 1

The ELF was produced by alternating-current electromagnets. The waveform was sinusoidal with a frequency of 100 Hz; the amplitude was adjusted according to the distance between the polar expansions (a). The TAMMEF was produced by supplying the electromagnets with an outgoing current from an amplifier driven by a signal from recorded music (b). The signal shown in (b) contains extremely variable frequencies, amplitudes, and waveforms, and was generated by playing Rachmaninov’s Piano Concerto number 2 in C minor Op.18 for piano and orchestra, the same used in the experiment. The oscillations are close together because the predominant frequencies are in the thousands of hertz.
