They Are Using Sound As A Weapon [InfraSounds] - Real Eyes_low.mp4
Published on Mar 15, 2020
Infrasound, sometimes referred to as low-frequency sound, describes sound waves with a frequency below the lower limit of audibility (generally 20 Hz). Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher intensities. It is possible to feel infrasound vibrations in various parts of the body.
