For awhile now researchers have thought that infrasonic sound could be the thing to explain the “feelings” of danger or fear ...

In Part 1 of this Design Idea (DI), we saw how a standard electret microphone capsule can be persuaded to detect infrasonic signals down to a fraction of a Hertz by adding some fairly simple ...

One of the most striking features of the Nord Stream events is its long-lasting seismic and infrasonic signals, the researchers found. These signals decay slowly over thousands of seconds -- much ...

This is the basis of what is called vibroacoustic syndrome—the effect of infrasonic output not on your hearing but on the various fluid-filled parts of your body. People don’t usually think of ...

It’s one of two rare machines at Lyman’s company, Infrasonic Sound, which cut the final mastered versions of vinyl records for acts like Radiohead, Ben Harper, Best Coast and No Age.

Part 2 includes refinements to make the circuit more usable while extending its detectable spectrum with an additional technique that allows us to hear the infrasonic signals. Although electret ...
