Spherical sound speakers for perfect acoustics:
Overheard from nature
Spherical Sound Speakers – Natural Hearing Restored
Spherical sound speakers are the only loudspeaker systems that reproduce sound the way it occurs in nature. This has numerous positive effects—not only on our hearing.

“People have repeatedly complained that they found music from conventional speakers loud and unpleasant, and that at a party or concert they could no longer talk to each other,” explains retired engineer Rudolf Mechow, who spent decades searching for the perfect loudspeaker. “While a volume of 100 decibels at a rock concert inevitably triggers stress reactions and can damage hearing, even days of camping next to a roaring waterfall at the same loudness would not have negative health effects on the auditory system. The song of a single bird penetrates an entire forest in all directions. But if we hang a loudspeaker in a tree to artificially reproduce the birdsong, it soon becomes hard to hear—even though the box has much more power than the little bird. Why is that? What makes the difference?”
The Right to Healthy Acoustics
When Mechow began his search for answers in East Germany in the 1980s, he discovered that “not a single one of nature’s answers to this question had been incorporated into man-made loudspeakers.” While conventional speakers work with nearly 100% direct sound, in nature “all frequencies spread out in every direction from a single point at the same moment,” as Mechow says. “In natural sound, only about 12–15% is direct sound—at the initial impulse of the sound. After this birth moment, the sound expands spherically, creating a spacious quality that makes it clearly audible across great distances with little loss.”
This spherical sound forms the basis for natural, healthy hearing as well as the preservation and resensitization of our auditory system. “It is my strong belief,” emphasizes Kerstin Brachaus-Mechow, longtime music therapist and wife of Rudolf Mechow, “that besides clean air, clean water, good food, balanced temperature, and natural light, our bodies also have a birthright to healthy acoustics.”
Healthy Hearing: A Sound Experience Like Nature
Technology produces individual, pure frequencies—a tone. Nature, however, creates sounds: complex spectra consisting of tones and their overtone structures. This combination results in specific timbres. The concert pitch “A4” therefore sounds different when played by each instrument or sung by each voice. The more information from this spectrum is lost, the more energy our subconscious spends trying to fill in the missing details. This makes deep relaxation of the nervous system impossible.
Surround-sound systems such as Dolby attempt to imitate the spaciousness of real sound. Yet since these systems still function with direct sound, they ultimately only trick the brain. Brachaus-Mechow even reports impairments of spatial hearing caused by such systems.
Spherical Sound: Authentic, Brilliant, and Incredibly Soothing
Once Rudolf Mechow understood the natural principle of spherical sound, he created a transducer capable of converting the direct sound of a standard speaker into natural spherical sound. Music, voices, and sounds are thus reproduced according to the laws of physics and acoustics, with the natural spectrum rendered almost completely and true to the original.
In this acoustic hologram, the listener perceives sound three-dimensionally, as though immersed in the middle of the sonic event. It feels like bathing in music. The sound is strikingly brilliant, clear, and precise. Every cell resonates, the mind rejoices, the body relaxes, and a sense of wellbeing spreads. This is nearly impossible to describe—it has to be experienced by sitting between two such transducers.
The Therapeutic Benefits of Spherical Sound
Personal tragedies, industrial espionage, and economic espionage threatened Rudolf Mechow’s health and nearly destroyed his research. Yet he and his wife continued to pursue their vision: music that not only sounds good but does good. The discovery that Mechow® transducers have not only auditory but also health benefits came almost by accident and later became central to their work.
This effect, however, is neither surprising nor “esoteric” but corresponds to a biophysical principle. Kerstin Brachaus-Mechow, who researches natural sound therapy, explains: “All matter—including our bodies—is composed of tiny particles that vibrate at specific frequencies. Under stress or illness, these rhythms become disrupted. A physical property of sound is that it permeates matter. In the Holographic Frequency Therapy® (HFT®) developed by Brachaus-Mechow, body cells can draw from a broad spectrum of frequencies the ones they need to restore their natural rhythm.”
She teaches this principle of sound-induced therapy at her Klanggesund® Academy in Mecklenburg-Vorpommern, Northern Germany, and now shares this knowledge worldwide. Given the growing disadvantages of biochemical therapies, the search for biophysical healing methods has become increasingly important.?
