AdvertisementInfrasound is the acoustic sound waves emitted below the normal human hearing level, and while higher frequency noises are louder close to the source of things like nuclear explosions and rocket launches, low-frequency infrasound travels further. Infrasound, also known as low-frequency sound, describes sound waves with a frequency below the lower limit of human audibility. There are monitoring systems around the world to detect and record infrasound at varying frequencies. It covers sounds below 20 Hz and down as far as 0.001 Hz. But its failures were also large and tragic.
