Excerpt from Rakuten ↓ While playing the music of "Tempo 116," it generates high frequencies that cannot be reproduced by CDs, supporting ultimate healing and inspiration. It is recommended for use in cram schools, clinics, offices, and homes for in-home care. What are high frequencies? High frequencies have traditionally been incorporated into religious rituals using bells and chimes since ancient times, and were considered essential items for meditation and maintaining altered states of consciousness. Later, in churches, they were said to have aided communication with God, guided by the low-frequency and high-frequency sounds of pipe organs. In recent years, scientists around the world have been paying attention to high-frequency sounds (sounds beyond the audible range), and research is progressing on the part where the skin's sensors perceive high-frequency sounds and transmit information of "comfort" to the brain. Until now, it was thought in the scientific community that sounds outside the audible range did not affect the body, but because the sounds of natural waves, the babbling of streams, and the calls of dolphins and birds are mixed with supreme high-frequency sounds, high-frequency sounds (sounds beyond the audible range) often strongly affect the parts that govern life, and it has been scientifically proven that relaxation, inspiration, and natural healing power are increasing. The biggest feature of the Zetten 116-AS is that you can freely design three high-frequency sounds and utilize your favorite high frequencies, and it is also equipped with a 10Hz (alpha wave) low-frequency sound. 1. Based on the healing effects of dolphin calls, the concept is to simulate the sounds of dolphins. 2. You can experience high frequencies up to 116KHz, and it is equipped with three functions to adjust each frequency and turn the sound ON/OFF. You can freely design your favorite high-frequency sounds, so you can experience the high-frequency sounds of nature indoors. 3. To expect the effects of high frequencies in a short time, it is equipped with a 10Hz (fixed) alpha wave sound. (The experience of high frequencies varies from person to person) 4. The output has been increased by 5 times, making it possible to experience it over a wider area. (Volume adjustment is now possible, so you can adjust it to suit the location of use) 5. The speakers are protected by a guard, so there is no need to worry about damaging the speakers even if you have children or pets such as dogs and cats.
