This twin spool design with the low pressure turbine operating at 60 Hz, a common electrical frequency, eliminates the need for a conventional power turbine.

Because the magnetic flux density is strongest twice every electrical cycle, the fundamental "hum" frequency will be twice the electrical frequency.

The sensors read the subtle electrical frequencies of the brain.

However, it was not the radiation of uncontrolled electrical frequencies.

Your artificially created brains function at a differ- ent electrical frequency than the human mind.

Other electrical frequencies are known to have specific effects on the body.

This Carnegie curve variation is the fundamental electrical frequency of the planet.

There can be no electrical frequencies in what you describe.

It is a chair called "Cerebrex," which is equipped with a headset that emits an electrical frequency.
