Infrasound is sound that is lower in frequency than 20 cycles per second, below the limit of human hearing. The study led by Robin Matoza, a graduate student at Scripps Oceanography, ...

Infrasound is too low-frequency for humans to hear. It has been mistaken for ghosts, has been known to cause nausea and headaches in humans, and is used to monitor the testing of nuclear weapons.

A researcher at Delft University of Technology (TU Delft) has refined the process for measuring, analysing and interpreting 'infrasound'- sound with a frequency below 20Hz. Lslo Evers, who this week ...

These kinds of low frequency or infrasonic sound waves, much lower than an audible voice, are already measured on Earth. The rumbling or "hum" can be generated by sources as diverse as volcanoes ...

THE64 SUB and THE100 SUB from ASCENDO push low-frequency reproduction with advanced engineering, deeper extension, and ...

Infrasonic sound can also make people nauseous and sick. Those physical and emotional reactions may explain why horror movies used to feature scary, low-pitched organ music, the researchers say.

Infrasound—sound that’s commonly (and incorrectly) thought to be below the threshold for human hearing—has often been claimed as a source of annoyance, nausea, sleep loss and anxiety, among ...

By ‘listening’ to infrasonic sound waves — sound below 20Hz, which is undetectable to the human ear — combined with machine learning, the device claims to be able to monitor an entire home ...

The scariest day of Pete Lyman’s life was the morning the movers came for his 1978 Scully LS-76 vinyl-cutting lathe. It’s one of two rare machines at Lyman’s company, Infrasonic Sound, which ...
