I don't know what that first thing is burning not falling for that again I don't care how hot she is nothing bigger than a finger is going up there
. Is that a subsonic Harmonic resonator? Patent pending. Why wouldn't I just buy that probably $2000-$8000 plug it in and measure the frequency return it and just buy a speaker and have it okay that same note aka frequency all day long. It's either going to be very low or very high. Subsonic means it the waves are moving slower than the speed of sound through air. When an object moves at a speed slower than the speed of sound in the medium, it creates circular shaped sound waves inside one another. So it's not Ultrasonic a high pitched frequency that's inaudible to humans or Infrasonic a low pitched frequency audible to humans. That machine claims neither just the harmonic waves it produces travel slower than the speed of sound. So are they audible? I out a fishtank on a speaker once every fish died from the sounds waves and vibration. Somebody buy one and use a guitar tuner and tell me the frequency and the note okayed and I can duplicate it for $30. You know a product is super uselfulk when there isn't a single review online and the only guy I ever saw say he bought one said alright they have a 90 day money back guarantee I bought it then never made another post
