<p>The generator includes an element for generating a succession of electromagnetic waves. It comprises at least one oscillating circuit (15a-g) to generate one or more wave harmonics from one or more oscillating waves at fundamental pre-determined frequencies. A controller mixes the waves which are emitted into a room of users. Each wave generated by mixing the waves is made up of the sum of a series of fifth, ninth, thirteenth, seventeenth, twenty first, twenty fifth and twenty ninth order harmonics w.r.t a fundamental frequency.</p> |
