New. Infrasound Amplifier / Taos Hum Amplifier / Psychic Power Amplifier / Brainwave Amplifier. The brainwave frequencies are: Alpha (8 Hz - 12 Hz - Awake, mild/moderate stimulation), Beta (15 Hz - 25 Hz - Awake, moderate/excited stimulation), Delta (0.5 Hz - 4 Hz - Stage 3 Sleep, Stage 4 Sleep), Theta (4 Hz - 8 Hz - Stage 1 Sleep and REM Sleep), and Spindles (12 Hz - 15 Hz - Stage 2 Sleep, often with K-Complex). You cannot measure brainwave BW frequencies unless you have an amplifier which will amplify electronic signals in the infrasound bandwidth (BW). Even the highest quality, most expensive audio amplifiers don't amplify signals much below 20 Hz (the human lower hearing limit) - they cannot amplify infrasonic BW sounds of the brainwave frequencies, so are useless for biofeedback purposes involving brainwaves or any other infrasonic BW sound, electrical, magnetic or electromagnetic phenomena. While oscilloscopes and spectrum analyzers will display brainwave frequencies, because brain wave signals are extremely weak (microvolts), only the most expensive scopes will amplify them enough for decent viewing or analysis (and these usually require 1X probes). For most oscilloscopes and spectrum analyzers, you need an external infrasonic BW amplifier to provide adequate signal boosting if you want to view brainwave signals more than 1 cm peak-to-peak on the scope display. Furthermore, since scopes are wideband, noise frequencies above the infrasonic BW will also be amplified and displayed along with the BW frequencies (e.g. 60 Hz electrical power interference), thus making viewing and analysis of the brainwave frequencies and other infrasound frequencies on a commercial scope much more difficult and sometimes almost impossible. And unamplified brainwave signals are useless for any direct application for biofeedback, other brainwave and other infrasonic applications. This infrasound amplifier will amplify infrasonic frequences from 0.25 Hz to 25 Hz, with strong signal rejection above 30 Hz. Input impedance is very high. Tunable gain (volume control) up to an incredible 1,000,000 (100 db). This amplifier, with the proper input transducer will amplify brainwave and many other infrasound BW signals as well, such as earthquake sounds, TAOS hum sounds, infrasonic weapon system sounds, low-frequency magnetic fluctuations, low frequency motor sounds and engine sounds, super woofer speaker outputs, and other low-frequency and sub-audio sounds. This is one Item in a group of closely related Items you may be interested in: (1) Wideband Ultrasonic Amplifier, (2) Infrasonic Amplifier - this Item, (3) Magnetic Transducer, (4) Ultrasonic Microphone, and (4) Soft-Pinch Electrodes. See my webpages for descriptions. Note that these amplifiers are all unique handmade creations so while I have limited quantity, the one you get may not be the exact one shown in the image as there are variations in external component (i.e. switch, connectors, volume control pot, LED) and label placements. Because these are handmade electronic creations, as opposed to mass-produced assembly-line equipment, these are all individually tuned and tweaked for optimum distortion-free performance. This special amplifier is not intended for any medical uses. We are not licensed medical professionals. We make no medical or paranormal (including but not limited to psychic powers) claims. NOTE: If psychic powers exist, this extremely low frequency amplifier may be useful to amplify psychic powers for psychic powers research. We make no claims that psychic powers exist. This amplifier can also be used for many general electronic laboratory, shop, automotive and hobby / craft uses. This Item does not include any infrasonic microphones, infrasonic electrodes, infrasonic probes or infrasonic transducers. Our Magnetic Transducer listed above works deep into the infrasonic BW frequencies (down to about 0.5 Hz) to detect extremely low frequency magnetic fields in conjunction with this infrasonic amplifier, and is great, for example, to detect brainwaves.
