1. A MADDENING SOUND.

Author

DICKEY, COLIN

Subjects
*AUDITORY hallucinations, *VLF emissions, *CONSPIRACY theories, *SOUND, *DELUSIONS
Abstract

The article discusses an auditory phenomenon and possible hallucination known as the Hum, conspiracy theories, and the potentiality of mass delusion. Emphasis is given to topics such as scientific investigation and data collection by teacher Glen MacPherson, low-frequency vibrations experienced as sound, and an experiment devised by MacPherson to block very low frequency (VLF) radio waves.

3. Hot Tips For Hot Dirt.

Author

Stevenson, Tony

Subjects
VLF emissions, RADIO noise, ANTIQUITIES, AMERICAN Civil War, 1861-1865, ARCHAEOLOGICAL excavations
Abstract

The article offers tips on how to get the best from the very low-frequency (VLF) machine and find relics in highly mineralized ground conditions and areas with high electromagnetic interference. He suggests always recovering the target during Civil War relic hunting to be sure as relics in plowed fields can sound like iron on the VLF detectors. He says that hunting in pinpoint mode allows him to quickly analyze targets based on a size-to-depth ratio.

5. ITS GOOD TO TALK: NEW COMMUNICATIONS SYSTEMS ENHANCE INTEGRATION OF SUBMARINES INTO TASK GROUPS.

Subjects
MILITARY communications, MILITARY telecommunication, TELECOMMUNICATION systems, COMMUNICATION & technology, RADIO frequency, VLF emissions, EXTREMELY low frequency radio
Abstract

The article offers information on various naval communications technology. It mentions that Very Low Frequency (VLF) and Extremely Low Frequency (ELF) radio waves are used in submarines since radio waves have a hard time penetrating water. It cites that high frequency (HF), very high frequency (VHF), ultra high frequency (UHF) and satellite communications (SATCOM) can also be used by submarines to remain in contact.

7. Magnetic Fields in the Office.

Author

Greiner, Ann Claire

Subjects
MAGNETIC fields, VIDEO display terminals, VLF emissions, ELF electromagnetic fields
Abstract

The article reports on the magnetic fields emitted by computer terminals in the office. A study conducted by the U.S. National Institute for Occupational Safety and Health accounted for the effects of very low frequency (VLF) but not extremely low frequency (ELF) radiation, which is the dominant radiation emitted by video display terminals (VDTs), as explained by Jerry Phillips, biologist at the Veterans Hospital in Loma Linda, California. Computer manufacturers such as IBM and Sigma Design plans to introduce monitors with reduced ELF emissions in 1991.
