A device that uses sound to affect the human body

The present invention relates to a device which acts on the human body by means of sound and to a recording medium, e.g. a tape cassette or a CD, for use with the device.

The present invention is based on three basic principles of music therapy. i.e. that low (deep) sounds have a gratifying effect when high - pitched sounds have an .1 exciting effect,. that rhythmic music has an activating effect when non-rhythmic music acts passivating, and that a high sound level has an aggressive effect when a low sound level acts passivating i.

These basic principles are generally valid, but there are exceptions. The basic principles have emerged through long-term therapeutic patient monitoring over a long period of time.

Music therapy is based on the music that the ear experiences through acoustic sensory channels.

The present invention is based on the fact that music that is transmitted directly to the human body through vibrational receptors of the nervous system can have a greater effect, i.e. it can provide greater muscle relaxation. By combining acoustic sensation and vibration to order y ie iskok prediction, a therapeutic effect is obtained in accordance with the present invention that affects both physical and mental suffering of patients. This combination is said in this specification; for simplicity, the vibration-acoustic echo, j i j 3 j il The vibration-acoustic principle gives the best possible sound transmission to both the ear and the body. The acoustic part can be treated with one or more loudspeakers or headphones.

2,8452 In accordance with the invention, a device is proposed according to the invention for transmitting sound from a loudspeaker to the human body in an efficient manner via air.

The features of said device for acting on the human body by means of sound are set out in the appended claims, as are the features of said artistic device.

The invention is described below with reference to the accompanying drawing, in which:

Figure 1 shows a device according to the invention:

Figure -2 is a partially exploded view of a portion of a device that provides a low frequency sound effect to the human body;

Figures 3, 5 and 6 show second, third and fourth alternative embodiments of the device shown in Figure X; and Figure 4 shows in block diagram form the units included in Figures 3, 5 and $.

Figure 1 shows a human body X placed on a closed body 6, in which case at least one sound opening 7 is placed, in which a loudspeaker 8 pointing towards the upper part of the body 1 is placed. A pad 9 is placed between the batten 6 and the body. against allowing good air to pass. The upper part X1 of the housing 5, which in the case shown forms the base of the mattress, may be e.g. plywood, said sound opening 7 being made in the upper part 11. To prevent possible loud damage, a sucrose 12 could be placed over the opening 7 to attenuate ambient radiation is a frame, -so housing 6. designed as a closed housing.

The padding 9 may be foamed or foamed rubber having:

V

closed cells. One could also imagine a mattress filled with inflatables or light plastic balls (e.g. styropor®) for use. The mattress or padding 9 has, as mentioned, an area 10 corresponding to the sound opening 7. Said area may be perforated, such as an opening 7, or possibly filled with foam with large open cells that allow air to pass in. The foam gives a certain supportive effect, especially as it is supported by said protective crossing while allowing air to flow well. Spirit16 is placed so that the part of the body to be affected lies at the opening 7 and the region 10. The membrane of the loudspeaker 8 is then connected to the body 1 via the air in said opening 7 and the region 10. The cushioning itself acts as a seal, making the connection between the loudspeaker 8 and the body 1 as efficient as possible. intensity, membrane moves, and s thus causing the body to move in low frequency.

The audio amplifier 3 having at least two audio channels has at least one output connected to the loudspeaker 8 and at least one output connected to the loudspeaker 2 for music. The signals coming to the amplifier 3 are fed, for example, from a cassette recorder or a CD player 4 and a signal generator 5. The signal generator 5 is arranged to supply sinusoidal sounds, pulses or other synthetic signals. The storage device 4 can be provided with a recording medium, e.g. a tape cassette or a CD containing suitable program material. The recording medium could have two or more audio channels, with at least one of the audio channels containing low frequency signals, preferably in the range of 30-120 Hz mixed with music.

The coin / other sound channel (s) of the art instrument could be arranged to supply stereophonic or quadrophonic music.

Thus, in this and the following description, it is to be understood that the signal generator S could in practice comprise one or; multiple storage media channels. The amplifier 3 could possibly be equipped with a low-pass filter (not shown) to supply the loudspeaker 8.

Thus, it is to be understood that either 1 89452 of loudspeaker Θ is fed at a pure low frequency in the range of 30 to 120 Hz. or modulated by music reproduced from loudspeaker 2, or that the sound present in loudspeaker 8 contains low frequency signals in said frequency range mixed with music which is also reproduced from loudspeaker 2. In this case, the signal generator of amplifier 3 consists mainly of player 4.

In repeated experiments, it has been found that the vibrational-acoustic frequency range in which the sound propagating to the human body appears to have the greatest effect, objectively measured and subjectively experienced, is between 30 and 120 Hz, most preferably in the range of 40 to SO 2. Particularly good results have been achieved in Octaves 40 - Θ0 Hz. Outside the frequency range of 30 to 120 Hz, there is subjectively no sense of vibration effect.

The therapeutic effect is achieved by placing the person in the most suitable way and as close as possible to the vibrating loudspeaker, in the example shown loudspeaker 8, and to a pleasant distance from the loudspeaker 2. which plays the music. The therapeutic device consists of the following parts briefly described above, i.e.: the vibration parts 6, 7, Θ, 10, which form a transmission device for reproducing sound in the frequency range of the vibration-acoustics; an acoustic component in the form of one or more broadband HiFi-quality loudspeaker cases 2 or pairs of headphones for reproducing music applied to the frequency used in the vibration loop; a multi-channel amplifier 3. which transmits blue vibrations (oscillation) and filtered music to the oscillation section 8 via at least one channel. tape player. preferably a conventional two-channel tape player 4. with one cassette tape * * - · -λ · '. ··,' ·; * ,. ··· -V.Λ, 7 · * '"' '',... '' X , · ",„ Pure music for music loudspeaker 2 is recorded on track 89452. The second track has a certain mix of music and low frequency sound, such as blue signals, recorded. The blue signals are rhythmized by a dual recording method specially developed for use in therapy. system, the so-called for mixing audio signals: ia the signal generator 5 is arranged to be individually adjustable with respect to therapeutically effective low frequencies applied to the loudspeaker Θ. provided they are not already input from the player 4.

In particular, it is to be understood that although only one loudspeaker 2 and one loudspeaker 8 are shown, the use of two or more music loudspeakers 2 and two or more low frequency loudspeakers Q is easily conceivable within the scope of the invention. If two or more loudspeakers 8 are used, a corresponding number of openings 7 and areas 10 must be provided.

When the pre-recorded software is used with the player 4 and played from the player 4, a signal generator 5 is then not required, but a signal generator 5 is required if it is desired to adapt the appropriate software and further develop it. A signal generator may also be desirable for research purposes and typically for medical treatment.

Fig. 3 shows how the housing of Fig. 1 could be replaced by a loudspeaker housing 1a 14 shaped in another way, in which a ΟΠ loudspeaker θ ', which can be folded from a vertical position with dotted lines), can be turned down (e.g. around the hinge 16 in a horizontal position). To ensure that the loudspeaker cover 14 lies horizontally, it can be supported by a wire, strap or the like 15 fixed at one end to the wall 17 as well as a hinge 16, and. at one end is attached to the outer part of the loudspeaker housing 14. When a person is to be exposed to sound, the person lies on a bench 13 89452 of a structure known per se, possibly similar in shape to bench 6, 9 in Figure 1. The external loudspeaker 2 'could be arranged e.g. in the bench 13 itself or in some other suitable way, e.g. that person 1 can get a good stereophonic sound pattern from it. After the person 1 is lying on the bench 13, either face up or down, the loudspeaker housing 14 with the loudspeakers 8 'is turned to the horizontal position shown in Fig. 3. The loudspeaker 8 'corresponds in function to the loudspeaker 8 of Figure 1,

Fig. 5 shows a variant in which the person 1 sits in a tilting furniture 18, which is a closed box structure, but has a sound opening for the loudspeaker 8'1, the loudspeaker θ '' having the same functions as in Fig. 1 or the loudspeaker 8 'in Fig. 3. than the embodiment of Figure 1, there is a sound opening 7 '' in front of the loudspeaker 8.

A corresponding sound opening 7 ’can also be found in Figure 3.

In the example of Figure 5, external loudspeakers are indicated by reference numeral 2 '', shown here in the form of headphones. It is to be understood, however, that external loudspeakers may have any suitable structure and / or location without limiting the scope of the invention.

The example of Figure 6 shows a variation of the embodiment of Figure 5. The tiltable furniture 19 is here of conventional construction, e.g. consisting of a frame with surfaces for leaning on a padded fabric. It may use one or more loudspeaker enclosures to affect the body of a person 1. In a non-limiting example of the invention, as shown, two loudspeaker housings 20 have been used. 21. Both of these, on the other hand, could consist of two separate loudspeaker housings for possibly better reclining furniture. However, it is important that the hard; the sound boxes are of the closed type to assert an external sound and to avoid an acoustic short circuit. In a known manner, loudspeaker housings are provided with loudspeakers 22, 23 and can be attached to the frame of a tilting piece of furniture -, '- - · „' ... i» .- j-.

In a facility for multi-disabled, mentally retarded patients, it was found that vibration-acoustic treatment produced an anticonvulsant effect at a frequency of about 40 Ha. The licvity3 effect of the seizures was so predominant that patients were more readily ready for manipulative physiotherapy during or after the vibration-acoustic effect.

Review experiments were performed on the opening angle of the members under convulsions with and without music. A clear difference in the opening angles of the effect of music was shown. a result. -------

The present device was also tested in the following spaces;

Retf syndrome ·, the pre-existing sea buckthorn of the “jerky” movements decreased, the patient was even able to fall asleep and a significant relaxing effect was observed (Retf syndrome named after Dr.med. Andreas Retf from Austria).

Closure (autism): Patients who avoided contact j were so impressed with the effect of vibration that they were able to get the staff to give more skin tightening / skin stimulation than without this effect. Here one could see the guidelines of a therapy where habituation under the influence of vibration acoustics could be. ,, Γ \, f; e 89452 move to situations where the music could be gradually muted or possibly eliminated altogether.

The vibrational effect of the vibrator was also tested on the plant staff for various ailments. The following was observed:

Neck / shoulder pains: Such pains, either of the muscle pain type or caused by stress due to various causes, were substantially alleviated at certain frequencies, especially about 68 Ki. Repeated treatments, up to 10 treatments each for 30 minutes, were shown to provide longer-term relief.

Witch arrow ·, Pain in the lower back area was relieved at certain frequencies, especially at about 30 Hz. Longer-term relief of pain caused by muscle tension was observed after repeated treatments.

Menstrual pains: Such pains and pre-menstrual tensions and the like proved to be relieved by using a special frequency »especially 52 Hz. Daily treatments in the "acute" phase as well as once a week in the intermediate phase, repeated over 2-3 seasons, appeared to produce a longer-lasting effect.

Asthma: Vibration-acoustic treatment at about 50 Hz; llai appeared to produce an effect that helps the patient to remove mucus from the airways.

During experiments performed in the local area, note ‘f.

matte the following: f

Stress - induced depression. A dramatic positive effect was observed after the first treatment. Each effect lasted about 30 minutes. The positive effect depends on 9 39452 both frequency (68 Hz) and music selection. Successful treatment was terminated after 10 treatments. During the last treatments, a large number of frequency bands and activating music were used.

. Sports injuries; The treatment has given a good result. Both acute myocardial infarction and postoperative recovery have responded positively to the frequency sequence 40 / 6O / 8Q / 6Ö / 40 Hz, with a duration of each frequency of approximately 6 minutes. Muscles and tendons in a tense state relax and can be stretched with less effort than without> *. vibration-acoustic treatment.

Rheumatism: Prolonged treatment (10 to 20 treatments) at frequencies of 68 and 86 Hz has provided lasting improvement for patients. with rheumatic pain and / or wear and tear. Treatment was given daily or every other day for 30 minutes.

Convulsive states: In muscle spasm, fading of the convulsive state was observed at a frequency of 40/60 Hz after about 2 minutes.

General excitement: The tuned frequency and music in an environment isolated from the outside world for 30 minutes produced a stress-relieving effect and seemed to give the person new vitality.

The above findings are purely empirical in nature. based on the observations made by the therapists and the descriptions of the subjects.the experiences they had during and after the treatments.

It is immediately understood that the sound housing shown in the drawings with its padding is intended only to, for example, clarify the invention without still containing any limitation of the set-up according to the following claims. Thus, the devices shown could be designed in any suitable way to affect the patient in the best possible way.

In addition to the mini sound recording medium, it should be noted that the rhythmic signal is made by recording a secondary frequency with a frequency different from 0.2 to 2 Hz on top of the primary frequency. The "rhythm rate" should be preset and tuned to the quality of music required to be used in addition to the low frequencies. The rhythm program is then recorded on another recording medium. e.g., for a track on a cassette tape, mixing sounds with selected, preferably filtered, music.

Pure music is recorded on another track. As mentioned earlier, it would be possible to use e.g. all the tracks on the cassette tape, using an audio head fitted to it, to improve the sound reproduction (e.g. two channels), and possibly by extending the rhythm instruction Absorb.
