what is infrasonic waves
Infrasonic waves are low frequency(less than audible sounds) sound waves and their propagation requires a medium. It's frequency normally below 20Hz. Infrasonic waves are sound waves in the frequency range 0.1 Hz to 20 Hz typically. Human hearing is confined in the sound wave frequency range of 20 Hz to 20,000 Hz.
