the resonator tube accordingly should have different diameters at the open and closed ends, respectively. 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. Easy Carrying: Designed to have light weight and compact size, the easy carrying and storage makes it an ideal gift. Figure 4 plots the pressure power spectral density (PSD) recorded at the array sensors for broadcast numbers 2, 3, 8, and 9 of Table II.

For our experiment we wanted to establish if infrasound in music generated unusual psychological effects, even in listeners unaware of its presence. Also known from the prior art is an infrasound generator based on a wave laser-induced shock wave, which contains a high energy ultrashort pulse laser, a housing in which a focusing system, a nozzle and a baffle with an opening are installed, a bell having a nozzle for supplying a working medium is connected to the housing.This thesis opens with a brief motivation for the creation of the source, in addition to previously developed infrasound generators and an overview of wind noise. To create infrasound that’s high enough amplitude to be perceptible, we needed to move a large volume of air every cycle of the soundwave. An arrangement as claimed in claim 1, c h a r a c t e r i z e d in that the resonator tube by means of an elastic annular element (17) is sealingly mounted to a socket (15) connected with the marginal portion of the aperture (14), which projects outwardly from the wall (13) and surrounds the resonator tube (10) spaced therefrom over at least part of the length of the resonator tube.

When we switched on the pipe, it soon became apparent that the suspension was itself a cause of distortion – it buzzed and rattled. NOTE: Low latency setting may result in high frequencies on some devices sound inaccurate, especially on higher volume. Original Assignee INFRASONIK AB Priority date (The priority date is an assumption and is not a legal conclusion. However, it can have various effects on the body, including anxiety, mood swings, and even hallucinations.

The modulator 15, due to the threaded connection, is installed inside the housing 1 with the possibility of movement along its axis (towards the channel 12 and vice versa). One solution of the problem is to make the resonator tube cylindrical with the diameter which is the optimum diameter considering the conditions at the closed end, and to provide the tube with a diffuser at the open end. In this instructable we will walk you through the process of building your own Infrasonic Subwoofer.

the resonator tube and the diffuser are dimensioned for the desired frequency and power as described above. modulator 15 (without chamfer 16) installed bell 17, designed to eliminate the dispersion of the sound stream.If you hold the shift key at the same time, the frequency will change by plus or minus 10Hz at a time instead. By mimicking this environment, the chances of experiencing something demonic increase significantly.
