... but it's totally silent. The sonic pulse is below the range of human hearing.
A quick overview follows: Remember the Hertz used would be amplified, although not by much. Gavreau almost brought down the house with no more than 2 watts of Infrasonic power.
100 Cycles Per Second (Hz)- nausea,vertigo,anxiety, fatigue,respiratory dysfunction.
60-73 Hz- sternal pressure, choking, breathing trouble,headache, abdominal pain.
43-73 Hz- IQ falls to 77% of norm,poor muscle control, slurred speach, blackout.
It's said High intensity/Low frequency weapons have been tested by many governments, for example:
A) Acoustic Bullets. waves emitted from 1-2 meter dishes. Results in blunt trauma,from discomfort to death. A Russian device is thought to exist that shoots baseball size 10 Hz "bullets".
B) US DOD has been playing with an acoustic rifle for soldiers. They could "dial in" the potential, from disable to kill.

No, they were Frank Herbert's idea.
