The Schumann Resonance is a resonance frequency that exists in the Earth's electromagnetic cavity; i.e. between terrestrial surface and ionosphere. German physicist W.O.Schumann first detected the resonant properties of this terrestrial cavity in 1954. It is said that the Schumann Resonance is a breathing phenomenon of the Earth that is lasting from old time of the Earth creation and is giving a positive effect to the human brain. Humans, animals and plants have become accustomed to this frequency of 7.83Hz over a very long period of evolution. But recently, many unnatural radio waves and electromagnetic waves disturb this frequency of 7.83Hz, it has changed the influence that it has on us. Our research was started from the point of view that [If Schumann Resonance Waves have a positive effect on the human brain, how does it react to human hearing?], it became clear that there was a surprising effect to both of hearing and sight. Then, we developed and manufactured a device to generate the 7.83Hz electric wave artificially, the Ultra-low Frequency generator RR-777 (Patent Pending).

B00005QZ16 Availability: Currently unavailable Score: 4.425 Category: Electronics Rating: 3.2 Votes: 11 Find similar products Acoustic Research TDS202 TDS Sound Enhancement Sound System (1-Speaker, Silver). From the Manufacturer The Sound Enhancer TDS202 from Acoustic Research (AR) is the first consumer product to feature True Dimensional Sound (TDS) technology. Originally introduced to the professional audio market in 1997, TDS unlocks hidden elements, such as background instruments and vocals, unintentionally buried in the mix. Patented circuitry provides an increase in voltage that, when coupled with the spectral decay effect, enhances the signal with a wider, more detailed soundfield. Sound Enhancer--which has been a key component in the production of soundtracks for such popular films as U-571 , The Mummy , and Jerry Maguire --uses only passive circuitry, ensuring the greatest possible signal integrity and purity of sound. Its stylish, sleek design--measuring 7.875 inches wide by 5.125 inches deep and 2.25 inches high--fits most existing audio racks or home entertainment centers. AR's Sound Enhancer requires no adjustments. L/R inputs and outputs simplify setup: just plug in a two-channel feed from a CD player, DVD player, MP3 player, or other audio source. When processed by the Sound Enhancer, the least audible frequencies are increased in amplitude without reshaping the loudness contour, revealing subtle elements in the original recording while managing dwell time; that is, the duration for which newly perceptible frequencies can be heard. Audio is then fed from the output jacks of the Sound Enhancer to your receiver, amplifier, or preamp. AR's Sound Enhancer is designed for all levels of music enthusiasts, from casual listeners to dedicated audiophiles. Given that the process of enhancing subtle nuances via an increase in voltage results in an improvement over a wide frequency range--20 to 20,000 Hz--the difference is noticeable in all audio components, from boomboxes to state-of-the-art DVD players.
