In electrical engineering, high-frequency (HF) is the description of frequencies outside of audible sound waves.
In acoustics, this frequency range is also called ultrasound.
Modern communication technology transmits data through high-frequency electromagnetic vibration/radiation; the frequencies used here are in the MHz and GHz range. Examples of this are cell phones, smartphones, WLAN, DECT, baby monitors, WLAN, mobile Internet…
In the last few years, today, and in the future, countless studies have been and will be conducted to prove the harmlessness or harmfulness of high-frequency, pulsed electromagnetic radiation on the body. The link between mobile radio radiation and brain tumors could only be checked by research and the legal system and adjudged by the Italian Supreme Court as conclusive at the beginning of October 2012. The knock-on effect of the discovery in Europe and the rest of the world is still unforeseeable based on 30 years of research.
High-frequency in geobiology and in practice
Geobiologists can recognize potential technical fault zones with appropriate measuring equipment and shield from them with adequate materials. We use T98 Alpha shielding paint, GPA shielding mesh, or NOVA shielding fabric to effectively shield from HF. T98 and GPA can also be used to shield from tension fields and the current (low-frequency).
