NASA's infrasound sensor is a highly refined microphone that is capable of detecting acoustic waves from 20 Hz down to dc, the infrasound range. The design is robust and compact, eliminating the bulk and weight found in other technologies.

2018年10月27日 · An infrasound sensor can be defined as an equipment sensitive to infrasonic pressure fluctuations and delivering an electric signal accordingly. It is associated with a digitizer (acquisition unit), and most of the time to a wind noise reducer (Marty 2019; Raspet et al. 2019), to complete the measuring chain. Recently, some infrasound sensors ...

Infrasound is a powerful tool for monitoring natural events like earthquakes, avalanches, volcanic eruptions, weather patterns and other atmospheric phenomena like meteors and auroras.

The purpose of this project was to create a wireless sensor array that could reliably locate infrasound sources. Infrasound is low frequency sound waves with frequencies below the lower limit of human audibility, 20 Hz. Infrasound sound waves are created from several natural phenomena such as earthquakes, avalanches, lightning, and volcanoes.

2021年10月18日 · The sensor filters out wind noise that can interfere with detection while using less power and much less space than currently available solutions. NASA’s infrasound sensor can detect tornadoes and clear-air turbulence hundreds of miles away.

Phenomena that generate a type of low-frequency sound known as infrasound could become easier to detect and measure thanks to a new technique under development at the Georgia Tech Research Institute (GTRI).

NASA's infrasound sensor is a highly refined microphone that is capable of detecting acoustic waves from 20 Hz down to dc, the infrasound range. The design is robust and compact, eliminating the bulk and weight found in other technologies.

2024年11月4日 · The infrasonic waves, characterized by their low-frequency nature, present a promising avenue for long-distance remote sensing, particularly in the monitoring of geophysical events with the potential for widespread destruction, such as earthquakes and tsunamis.

This page describes basic function of Infrasonic sensor. It mentions working Infrasonic sensor network. Infrasonic is the term which refers to study of sound waves which are below the frequency limit that humans can hear.
