New Scripps study of low-frequency sound from Mount St. Helens and Tungurahua volcanoes provides explanation for how the large-amplitude signals from eruptions are producedNew research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. Researchers at Scripps Institution of Oceanography at UC San Diego speeded up the recorded sounds from two volcanoes and uncovered a noise very similar to typical jet engines. These new research findings provide scientists...
Researchers have discovered that a frog that lives near noisy springs in central China can tune its ears to different sound frequencies, much like the tuner on a radio can shift from one frequency to another. It is the only known example of an animal that can actively select what frequencies it hears, the researchers say.The findings, from a collaborative effort led by the University of Illinois and the University of California at Los Angeles, appear this week in Proceedings of the National...
A new theory claims that so-called "shadow bands," which sometimes pass across the ground during an eclipse, might be produced by sound pulses.These bands, which pass across the ground during totality"”when the Moon completely covers the sun, are considered by some to be caused by atmospheric turbulence. However, astrophysicist Dr. Stuart Eves says shadow bands could be caused by something called infrasound.Before totality, these bands have been observed to pass over the ground in the...
