CUEI Infrasound generator, low frequency stable pulse generator with DC 5V 0.5A 7.83Hz Schumann resonance and office cabinet

Product Information

In the hole formed by the protrusion 14, coaxially to the housing 1 coaxially to the channel 12, a modulator 15 is installed, having the form of a thick-walled cylindrical pipe, mainly of variable cross section. The Holliman sub has been discussed on this forum a few times over the years but I didn't check the archives until after my post. the resonator tube accordingly should have different diameters at the open and closed ends, respectively.

The sound generator is mounted by means of a cylindrical socket or tunnel 15 which is connected at a flange 16 with the marginal portion of the aperture 14 and projects outwardly from the boiler wall 13. Unlike all design’s prior, the Wilson Benesch Torus Infrasonic Generator eliminated the cabinet from any and all structural responsibilities. A 'normal' sub would be handy as well unless you had monster fronts like ATC SCM 300A - 300 litre 15" woofer active studio monitors or Acoustic Energy AE4's (which I've owned in the past. Finally, adjust the volume of the audio amplifier until you hear a low-frequency sound coming from the speaker. the resonator tube is resiliently suspended in the tunnel by means of an annular diaphragm 17 of steel sheet, which has a thickness of some millimeters and is sealingly mounted at the outer end of the tunnel, the diaphragm being connected at the outer periphery thereof to the tunnel and at the inner periphery thereof to the resonator tube.What I was asking about is that in your post you seem to imply that the Infrasonic Generator is unsuitable for Hifi or AV use. We were working on a very tight budget so our acoustic canon was made from stiff sewer pipe around 7 metres long.

The study of such sound waves is sometimes referred to as infrasonics, covering sounds beneath 20 Hz down to 0.Launched in 2006, the Torus Infrasonic Generator remains a significant departure from all prior art. SNRs in the range 5 – 15 dB indicate that this technology has merit as a field-deployable infrasound generator. This purpose is achieved by the arrangement having obtained the characteristics according to claim 1. The intensity of the infrasound waves can be changed by changing the laser pulse energy or changing the working medium (see CN 102324228 (A), published January 18, 2012). For example, the University of Mississippi designed and built a large horncoupled electropneumatic loudspeaker for the U.
