Infrasound, also known as low-frequency sound, describes sound waves with a frequency below the lower limit of human audibility. It has the ability to get around obstacles with little dissipation. 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. Multidisciplinary projects are hard due to their complexity. But its failures were also large and tragic.
