Frequency (Hz)

The number of electromagnetic pulses a device delivers each second, measured in Hertz (Hz). Frequency is independent of field strength: a high-frequency signal can still have a low Gauss output, and the reverse. It is one of the main variables that describes how a device operates. PEMF frequencies are often grouped into named ranges borrowed from EEG convention, Delta (0.5 to 4 Hz), Theta (4 to 8 Hz), Alpha (8 to 12 Hz), Beta (12 to 30 Hz), and Gamma (above 30 Hz), which show where a setting's pulse rate falls. Those names label the pulse rate only and do not by themselves indicate a specific effect in the body. A specification sheet that quotes pulses per second may be counting something different, so see Pulses Per Second (pps) before comparing the two numbers.
