"Balloon detects first signs of a 'sound tunnel' in the sky; Atmospheric analog to ocean’s acoustic channel could be used to monitor eruptions and bombs" - Science Magazine - SCW Newswatch
Science Magazine reports on efforts to discover a "sound tunnel" in the atmosphere, similar to one deep in the oceans.
"About 1 kilometer under the sea lies a sound tunnel that carries the [sounds] of whales and ... submarines across great distances. Ever since scientists discovered this Sound Fixing and Ranging (SOFAR) channel in the 1940s, they’ve suspected a similar conduit exists in the atmosphere. .... Now, by listening to distant rocket launches with solar-powered balloons, researchers say they have finally detected hints of an aerial sound channel ... [I]t does not seem to function as simply or reliably as the ocean SOFAR. If confirmed, the atmospheric SOFAR may pave the way for a network of aerial receivers that could help ... detect remote explosions from volcanoes, bombs, and other sources that emit infrasound — acoustic waves below the frequency of human hearing. ..."
