Infrasound, also known as low-frequency sound, describes sound waves with a frequency below the lower limit of human audibility. Multidisciplinary projects are hard due to their complexity. But its failures were also large and tragic. It was none of those. We were a little bit surprised about that.
The infrasound is reasonable to use for curious people.
