Application of somatosensory music therapy

Vibroacoustic has attracted wide attention in the advanced countries of the world.

What is somatosensory music/sound? Musical vibration that can be felt by the body is sensory music. When a person makes a sound, touch his back and you can feel the vibration. About 70% of human body weight is water. The impedance of water is much higher than that of air, and the effect of vibration transmission is much better than that of air. The fetus develops with the vibration of the mother's voice. In fact, this is somatosensory music/sound. Although we grow up to be adults, this fetal development environment still subconsciously resides in memory. For example, when a baby cries, once it is picked up by the mother, it immediately calms down, because the mother's sensory vibration makes the baby feel safe and comfortable.

Vibration and audio equipment based on the principle of somatosensory music is called somatosensory sound. Through this kind of sound, people can not only listen to music, but also feel the music and sound vibration, giving people a strong music/sound experience, which is a new entertainment electrical equipment.

Application of somatosensory music therapy

(1) Somatosensory Music - four-dimensional sound:

In general, music regeneration is achieved by amplifying the signal with an amplifier, sending it out from the loudspeaker, and then vibrating through the air to reach the human eardrum. Usually we can hear the bass part of music is 50 Hz-150 Hz, because although the best organ can produce 16 Hz bass, the best amplifier and loudspeaker can only produce more than 20 Hz frequency. The somatosensory sound is different. The maximum range of somatosensory sound can express 16Hz-20000Hz. In addition, the 150 Hz-16 Hz low-frequency part of the electrical signal is amplified by an amplifier, and converted into physical vibration by a transducer for human conductive sensing.

We know that the bass and gravity of the low frequency part of 20-50Hz are greatly enhanced, accompanied by a strong sense of vibration and impact, giving people a very strong sense of presence. Not only that, the frequency range of 20-50Hz can give people the pleasure and intoxication of psychological and physiological pleasure, and can achieve the best mental relaxation effect. In other words, how to faithfully reproduce music in the frequency range of 20-50Hz is the technical specialty of somatosensory audio today. Because it is extremely difficult for traditional audio technology to regenerate low frequencies below 40Hz.

This new concept of audio technology will lead to a technological revolution in the fields of audio, music and so on. Its practical application field is also very wide. Such as:

Music: The body can perceive the low-frequency part of 50-20Hz that the human ear can not hear, and can obtain great impact beyond the stereo effect, which can be called four-dimensional sound.

Video (movies, TV, DVD, games): The body can perceive the low-frequency part of 50-20Hz that the human ear can not hear, and can get a realistic sense of presence.

Leisure: relieve mental pressure and get high quality rest;

This kind of four-dimensional stereo stereo sound can make people get the best music intoxication and presence. The fluctuating somatosensory music produced by it gives people a brand-new experience of music and the best leisure enjoyment of relieving mental pressure. The somatosensory sound technology is the basic technology of the new sound, which has a wide range of applications and extensions. Far-reaching. It can be used for pure music appreciation, DVD and video games, relaxation to relieve mental pressure and somatosensory music therapy.

(2) Somatosensory music therapy, a brand-new acoustic therapy technology:

The World Health Organization (WHO) at the health symposium "unanimously praised the scientific validation of effective music therapy, its effect is far higher than the traditional Western medical method of 4-8 times". Music therapy has more than hundreds of clinical reports in the world, which has aroused great attention and research in the medical field. Nowadays, more than 5000 medical professionals (MD, PHD, postdoctoral Pa and academicians of science) in Europe and America have participated in the research. More than a dozen music therapy colleges in the United States have trained a large number of music therapists every year. More than 50,000 people nationwide have received certificates of qualified music therapists. They have served in major medical schools and outpatient clinics in the United States.

The academic research, product development and application of music somatosensory vibration in the field of music therapy have a history of several decades in Europe, America and Japan.

At present, China is in the stage of rapid economic development, and the increase of social stress factors makes the incidence of sub-health, psychosomatic diseases and lifestyle-related chronic diseases increase year by year. Musical somatosensory vibration therapy is a new concept of treatment. It has no side effects, does not cause medical pollution, low cost, easy to operate, not only suitable for hospitals, individuals can also be applied in the family, office, can be said to be a true sense of natural therapy, green therapy. As a mature technology, music somatosensory vibration therapy has a definite clinical effect and broad application prospects. Therefore, it is of great social significance to strengthen the research and application of music somatosensory vibration therapy. The therapeutic effect of somatosensory music is far from that of ordinary mechanical massage. It produces a complex pulse waveform rather than a single mechanical vibration, which makes the whole body feel like a ripple of vibration effect. "Music itself has the ability to relax, and when added to vibration, it strengthens the effect and stimulates a relaxation response," says Chris Brewer, a music and education consultant in North Carolina. "This process is physical relaxation, slow heartbeat, and relaxation."

One theory holds that sound vibration is like an internal massage for human organs, tissues and cells.

Somatosensory music therapy can stabilize the mind and reduce blood pressure. Such as abdominal pain, wheezing, aphasia, autism, bedsore, stroke, cerebral palsy, circulatory system diseases, hernia, lethargy, weakness, cystic adenovirus, diabetes, menstrual difficulties, menstrual pain, menstrual tension, muscle pain, drunkenness, insomnia, back pain, migraine headache, muscle spasm, shoulder pain, constipation, etc. Parkinson's disease, arthritis, rheumatism, etc.

Somatosensory music therapy (SMT) is a new acoustic therapy technology. The development of this technology is based on the general understanding that external vibration can affect body function. Studies have shown that external vibration generated by specific music or sound can have a good effect on the internal functions of the body. Therefore, somatosensory music therapy is effective, and it is suggested that somatosensory music therapy be used in nursing to improve patients'physical function and treatment environment.

2. Frequency range of somatosensory Music Technology

At present, there are three kinds of somatosensory music technologies: full-band music (FFM) system, selective low-frequency (SLF) system and quantitative mechanical vibration (QMV) system.

Full-band music systems have been proven to be effective in relaxing nerves and muscles and alleviating anxiety and pain. The system uses a single sound source and multiple loudspeakers or transducers to generate vibration to the whole body. Standard sound sources and power amplifiers are currently used (of course, sound sources can also be obtained from computers or other electronic instruments, but their vibration doses to the human body have not been measured).

Mr. Olav Skille, a Norwegian educator and clinical physician, has developed a musical somatosensory therapy device. His experimental frequency ranges from 30 to 120 Hz, of which 40 to 80 Hz is the most beneficial. Skilli conducted a 40,000-hour clinical trial of somatosensory music therapy, which proved that the frequency range was very effective in the treatment of autism, migraine, muscle cramps, cerebral palsy and other diseases. Petri Lehikoinen, a researcher and lecturer in music therapy and special education at the University of Helsinki, believes that 20-113Hz has a better therapeutic effect on musical somatosensation.

Kris Chesky, director of the Texas Center for Music and Medical Education and Research at the University of North Texas, found that music somatosensory therapy at a frequency range of 60-600 Hz at a specific amplitude was the best way to relieve pain. It is known that the vibration in this frequency range can stimulate the Pacinian globule, which distributes at the nerve end of the subcutaneous nerve. Its function is to regulate the sensation of pain, pressure and itching. Vibration in the frequency range of 60-600 Hz promotes pain relief, and Chesky found that 60-300 Hz contributes most to the therapeutic effect.

Studies have shown that vibration is effective in relieving pain in most areas of the body, and it works better when vibrating near pain areas.

3. History of somatosensory music therapy

Acoustic vibration has many applications in medical treatment, such as ultrasound for ultrasound imaging and lithotripsy treatment, low-frequency vibration for the treatment of muscle and joint pain in vertebral finger compression, pulse micro-current for improving therapeutic effect by acupuncturists, etc. Somatosensory music therapy, on the other hand, combines the above principles to form a therapeutic effect of vibration on the whole body, which is very effective in relieving stress and controlling pain.

Somatosensory music therapy appeared almost simultaneously in the United States and Scandinavia in the 1970s and 1980s. Olav Skille, a Norwegian educator and clinical physician, successfully developed a low-frequency music somatosensory therapy chair in the early 1980s. Petri Lehikoinen, a researcher and lecturer in music therapy and special education at the University of Helsinki, designed and developed a low-frequency music somatosensory instrument (called psychoacoustics instrument), which uses computation. The rhythmic low-frequency impulse vibration controlled by the machine makes certain parts of the body resonate to obtain curative effect.

Byron Eakin of the United States completed the development of music somatosensory equipment in 1985 and successfully commercialized the products of music somatosensory reclining chair and mattress. These products are very practical and are designed for full-band music vibration with a single sound source. Kris Chesky designed a music shaking table in the late 1980s, which can detect the vibration frequency and amplitude of specific parts of the body, but this shaking table has not been commercialized. At present, most of the music somatosensory therapy devices widely used in the world are developed by Byron Eakin.
