The Hertz (Hz) is the unit used to measure frequency. Hertz gives the numbers of repeated oscillations (processes) per second.

In electrical engineering, high-frequency (HF) is the description of frequencies outside of audible sound waves.

Interference describes the superposition of two or more waves based on the principle of superposition – therefore the addition of their individual amplitudes.

Low-frequency (LF) is a technical description of frequencies that are in the range of audible sound waves.

Natural radiation is a collective term for all of the types of the Earth’s natural faults zones. Natural radiations are generally physical phenomena.

SAR is the abbreviation of Specific Absorption Rate. SAR is the measure for the absorption of electromagnetic fields in biological tissue.

Shielding is the protection from the effects of external fault zones and environmental influences (on a person’s health most of the time).

A vibration (also oscillation) is described as a measure that repeats after a determined time interval.

The volt defines the tension of an electric line. The tension in the power line (copper) defines the number of amperes that can be transported and almost builds the framework for transmission.

Water veins are essential for providing the ground and plant world with nutrients. Simply put, without water veins, we would not have any vegetation (see deserts).
