Yes! This issue has been researched and tested over the last 15 years. There are two types of EMF’s….  Coherent (good) and Incoherent (bad).   Incoherent EMF’s are made up of thousands of random frequencies (Like microwaves, and wireless phones). Those are not so good...... A sound wave, a single tone, music or sound in itself, is a coherent frequency. Our VibraSonic emits single sine wave forms that are Coherent and safe for electromagnetically sensitive people.  Other forms of electrical equipment have Incoherent random waves that can affect electromagnetically sensitive people.
