NASA Langley Research Center scientists have developed a microphone that detects infrasound, i.e., acoustic waves ranging from 20-Hz frequencies down to DC. Infrasound is emitted in a number of hazardous atmospheric phenomena, including aircraft wake vortices, clear air turbulence, and tornadoes. It is also emitted by seismic events such as underground nuclear tests, digging of tunnels, etc. Infrasound propagates hundreds of miles and can penetrate walls, mountains, and other obstacles without loss.
