Sound Noise and Music Curiosities
Which of these bizarre physical phenomena allows the military to create a literal acoustic weapon that can focus sound into a narrow, precise beam?
Correct
Parametric sound amplification, often called a parametric speaker, uses ultrasound to create a narrow beam of sound that only people in a very specific spot can hear. It is like a laser pointer for your ears. Quantum resonance is just a fancy science term that does not actually turn sound into a beam weapon. Subatomic frequency modulation is total gibberish made up for sci-fi movies, and hyper-sonic gravity waves are a wild concept that definitely do not exist in your local hardware store.
