Description

Stress relief system using sound source coordinated with heart rate}

The present invention relates to a stress relieving system, and in detail, recognizes a BPM (hereinafter referred to as'Healing Beat') equal to a heart rate during a subject's prior stabilization and uses the sound source to apply it in an anxiety situation exposed to a stress source. It relates to a stress relieving system using a sound source linked to a heart rate to relieve anxiety to a level before inducing a stress source.

Modern society diagnoses various diseases under the influence of highly developed medical technology and science and technology and is among convenience and material abundance, but rapidly changing social environment, excessive competition, dehumanizing phenomenon, social psychological crime, infectious disease appearance and aging, etc. Due to the occurrence of various social problems, anxiety and stress are acting as a major threat to modern people's mental and physical health.

In particular, stress caused by anxiety has emerged as a very important issue in modern society, and as anxiety reactions are known to cause certain disorders of the body or mind, such as stress, depressive disorder, and mental disorder, or to cause health disorders, anxiety Proper regulation has become an important factor for health promotion.

As a physiological response of anxiety, cortisol secretion increases and immunosuppressive action occurs. In addition, the secretion of catecholamines such as epinephrine and norepinephrine increases, and the sympathetic nervous system reaction is enhanced. As a result, heart rate, blood pressure, respiratory rate may increase, muscle tension, and gastrointestinal motility may decrease, and psychological reactions may include depression and anger.

This persistent and excessive anxiety is caused as a stress source and maintains the homeostasis of the human body, physical reactions such as the cardiovascular system, musculoskeletal system, emotional stability, instability to immune function, hypertension, sleep disorders, etc. Edo also causes a lot of losses.

 Therefore, as a method for alleviating anxiety, it is controlled by administering various sedatives medically, but sometimes excessive control affects the heart function, increasing the incidence of side effects and medical accidents. It also causes.

Therefore, in recent years, the intervention for sedation to stabilize anxiety is a very important part, and as the interest in complementary alternative therapy, which is not only drug therapy but also non-drug therapy, has increased, integrated care is emphasized.

 Existing experiments to relieve anxiety include the effects of aroma essential oil inhalation on stress, anxiety and depression, the effect of foot massage on stress, immunity and fatigue, the effect of forest treatment on mental and physical stability, and neurofeedback training in late adolescents. The effects of physical and emotional stress responses and self-regulation and the effects of exercise on physical and mental health have been progressed.

However, in the case of aroma essential oil inhalation and foot massage, a trained expert must provide the technology, and forest treatment and exercise are somewhat difficult to practice in daily life when the subject has a physical disability, and are affected by weather and place a lot Therefore, it is limited in many ways.

In addition, in the case of neurofeedback training, it is difficult to mediate acute or persistent stress because special equipment, facilities, and space are required.

Among them, music-based stress intervention reduces anxiety, stabilizes vital signs, is non-invasive, cost-effective, and has no side effects.

Music affects the limbic system, and the aesthetic pleasure perceived by the right cerebral hemisphere acts on the pituitary gland to secrete endorphins, reducing heart rate and blood pressure when listening to music. In particular, recent experiments show that people feel psychological stability in the biological rhythms associated with natural forms of body movements, such as heartbeat and walking tempo.

However, most of the previous experiments of stress intervention through music therapy have been limited to specific genres preferred by patients such as classical or ballad, or limited to only the differences between before and after the treatment, so that the lasting effect is often unknown.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the stress relief system using a sound source associated with the heart rate of the present invention.

1 is a conceptual diagram of the present invention, Figure 2 is a block diagram showing the configuration and connection relationship according to an embodiment of the present invention, the present invention is an optimized sound source by reflecting the heart rate of the individual's mental stabilizer Healing Beat (Healing Beat) ) To relieve mental stability and stress by using under various stress or tension conditions, and more accurate personalized stress relief along with the basic configuration of the collection unit 110, sound source management unit 120, and output unit 130. It consists of a feedback unit 140 that is a support configuration for.

The collection unit 110 is configured to measure the heart rate of the subject, but to extract the heart rate of the mental stabilizer. For the present invention, it is necessary to basically check the heart rate of the subject, especially the heart rate, and for this purpose, various means for measuring the heart rate can be applied.

In addition, in order to obtain a heart rate in a state that is as close as possible to the ballast, a heart rate determined as the most stable state is extracted through a number of measurements over a period of a state in which a stress source is removed rather than a one-time measurement.

To this end, the collecting unit 110 includes a measuring unit 111 that continuously measures the heart rate of the subject, a matching unit 112 that receives and matches the heart information corresponding to the measured heart rate, and the heart information. It may be composed of an extraction unit 113 that extracts the heart rate of the ballast by analyzing the heart rate.

That is, the heart rate is continuously measured in the absence of a stress source or as much as possible, and the heart rate information is input together. Preferably, the heart rate variability (HRV) is measured after continuously measuring for a set time using an autonomic nervous system measuring device. On the basis of this, it is also possible to quantify the balance of the autonomic nervous system (Balance of Autonomic Nervous System) using a standard induction method and use the displayed value as mental information. This can be quantified from 1 to 10. The higher the value, the higher the value is judged to be exposed to anxiety and stress, and the lowest value can be recognized as the mental state of the stabilizer.Along with this, a survey and temperament anxiety to understand the mental state It can also be measured and reflected in mental information.

The sound source management unit 120 is configured to search for a sound source having a BPM corresponding to the number of beats of a subject's mental stabilizer, while receiving and storing sound sources for each beat per minute (BPM). It is possible to utilize various music-related sound sources that can stabilize the mind and body, and it is also possible to artificially change the BPM by adjusting the speed of a specific sound source. desirable.

Since it is a range of 60 to 100 times per minute, which is the range of a person's normal heart rate, a sound source tailored to this is input.

The sound source management unit 120 includes an input unit 121 for receiving a sound source, an analysis unit 122 for analyzing the BPM of the input sound source, and an alignment unit 123 for sequentially sorting sound sources according to the analyzed BPM. When inputting various sound sources that are thought to be effective in relieving stress, it is analyzed and automatically classified for each BPM, so you can easily find and use the necessary sound sources later.

In addition, the sound source management unit 120 may be configured to assign and manage sound source information including scales, chords and chords constituting the sound source, and musical instruments, and a sound source suitable for sound source information set by a pre-expert is recommended or system It can also be configured to exclude a sound source that is not in contact with the sound source information.

This is to provide music having an optimum effect as the scale of the music, the progression of chords and chords, and the musical instrument can affect the stress relieving effect. In the experimental example of the present invention, the GCDG is repeated with a four-fourth beat. As a pattern of rhythm composed of chords, ensemble music of the keyboard and guitar is used, but it is natural that sound sources of various characteristics can be utilized.

The scale used in the sound source means the arrangement from one note to one octave higher. The notes used vary depending on the scale used to make the music, and the mood is determined accordingly. Most of the music we listen to uses the Ionian scale or the Aeolian scale, which are called the major scale and the minor scale, respectively.

This means that the music most familiar to our ears is made using the two scales directly above. Major scale music creates a bright atmosphere, and Minor scale music creates a dark atmosphere. The music of the Healing beat uses the Major Scale to create a familiar but bright atmosphere in our ears.

The chords used are stacked on top of each note of the scale mentioned above and are called diatonic chords. It is a code created using notes belonging to the scale, so it can be said that there is no heterogeneity at a given scale. Healing beat uses music composed on the basis of G Major scale, and the Diatonic chord is G, Am, Bm, C, D, Em, F#m7(b5). Among them, except for F#m7(b5), which can be considered unstable in composition, it was made with the remaining six chords.

Chord's progress is a type that can be easily found in many songs, with the progress of 1-6-4-5 roads being the most commonly used. The most natural progression within the Diatonic Chord is selected using the progression of 4-5-3-6 roads and the progression of 2-1-4-5 roads, which are also common in the bridge part. The previous 1-6-4-5 degree progression reappears, ending the song with a familiar feeling.

Melody's progress uses music that is well-predictable, and avoids too much leap (over 8 degrees) or notes that are not included in the scale. It also excludes the progression of symptoms that may cause you to feel uneasy.

It was mainly composed for easy listening using sequential progression (up and down), and it was necessary to maintain a moderate speed to make the BPM from 60 to 100. Don't feel it.

The choice of musical instrument will select the guitar and piano, which are the most easily accessible instruments in the surroundings. The piano is used to play the background as a chord, and the music that plays Melody as the guitar is used on it.

The output unit 130 is configured to output a sound source searched through the sound source management unit to a target person, and is used for sound output means such as a speaker and a headphone.

The feedback unit 140 is configured to find a sound source optimized for a user among sound sources having a similar BPM within the same or set range, and the collection unit 110 corresponds to a sound source output through the output unit 130 The first tracking unit 141 for collecting the change in the heart rate collected through, and the other sound source having the same BPM as the output sound source and another sound source having a BPM in the upper and lower set range corresponding to the output, the collection unit ( Optimal stabilization value of the heart rate by analyzing the collection results of the second tracking unit 142 and the first tracking unit 141 and the second tracking unit 142 for collecting changes in the heart rate collected through 110) It is provided with a calculation unit 143 for calculating the optimal sound source representing.

As mentioned above, the heart rate of the initial stabilizer is extracted through the collection unit 110, but as it may be difficult to create a situation without any stress, a sound source having an optimized BPM through this feedback unit 140 Complementation can be made so that it can be found later.

Figure 3 is a flow chart showing the procedure according to the application of the present invention, the procedure for alleviating the stress of the user by applying the system of the present invention through the above-mentioned configuration is as follows.

In the first step (S 110), the heart rate of the subject is measured, but the heart rate of the mental stabilizer is extracted.

The first step (S 110) is the step of continuously measuring the heart rate of the subject (S 111), the step of receiving and matching the heart information corresponding to the measured heart rate (S 112), and according to the heart information By analyzing the heart rate and extracting the heart rate of the stabilizer (S 113) may be subdivided to proceed.

In the second step (S 120 ), sound sources are input and stored for each beat per minute (BPM).

The second step (S 120) includes receiving a specific sound source (S 121), analyzing the BPM of the input sound source (S 122), and sequentially sorting sound sources according to the analyzed BPM (S) 123), and may be configured to assign and manage scales, chords and chord progressions that constitute a sound source, and sound source information including musical instruments.

The next third step (S 130) is a step of searching for a sound source having a BPM corresponding to the heart rate of the subject's mental stabilizer.

In the next fourth step (S 140), the sound source searched through the sound source management unit is output to the target person.

The fifth step (S 150 ), which may be additionally performed, is a step of finding an optimized sound source for a user among sound sources having a similar BPM within the same or set range, corresponding to the sound source output in the fourth step (S 140 ). Collecting a change in the heart rate of the subject in response to the output (S 151) of collecting the change in the heart rate of the subject, another sound source having the same BPM as the output sound source, and another BPM having a BPM in the up and down range. It can be subdivided into steps (S 152) and analyzing the collected results in the previous steps (S 151 and S 152) (S 153) to calculate the optimal sound source representing the optimal stable heart rate.

There was a significant difference between the two groups (t=-7.633, p<.001).

3. Discussion

In this experiment, autonomic nerve balance, heart rate and anxiety were measured in order to confirm the effect on the body's anxiety resilience when applying the same Healing Beat to the resting heart rate of each subject in an anxious situation exposed to a stress source. In order to verify the variability between the autonomic nerve balance and the heart rate, the experimental measurement period is before the experimental treatment, after exposure to the stress source, and 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 35 minutes, After 40 minutes, a total of 10 measurements were performed to confirm the effect on the resilience of variables by time point. Anxiety was measured twice before and after experimental treatment.

In order to increase the anxiety of the subjects before the experimental treatment, they were exposed to stress sources by using arithmetic calculations. As a test treatment, a Healing Beat induction application consisting of BPM equal to the average heart rate at rest of each subject was applied to the experimental group at a volume of 40 dB through headphones, and no treatment was provided to the control group.

 In this experiment, subjects were artificially provided with a stress source that was often felt in everyday life. Ward [21] said that when exposed to a stress source of cancer, the sympathetic nervous system activity increases and the parasympathetic nervous system activity decreases. Therefore, the arithmetic operation used as a stress source in this experiment is a level of stress that can be experienced in everyday life. In order to check the extent of the stress source on the physiological response of physical anxiety, autonomic nerve balance, heart rate, and anxiety were measured after providing the stress source. It was confirmed that it had an effect of causing anxiety in a circle.

 To investigate the effect of applying Healing Beat on anxiety, the autonomic nervous system response, the autonomic nervous system response, was measured. The autonomic nerve balance increased in both groups when the stress source was provided, and the experimental group showed a significant difference from the control group after 30 minutes, and decreased continuously after 35 minutes and 40 minutes when measured in 5 minutes increments after the experimental treatment was provided. . On the other hand, the control group did not recover to the initial value even after 35 minutes after providing the stress source, and after 40 minutes, it decreased below the initial stress index level, which means that Healing Beat has an acute phase effect on the autonomic nervous system. In view of these results, applying the Healing Beat reduces the autonomic nerve balance to the level before inducing the stress source, and it is confirmed that there is an effect of recovering from an anxiety response after 30 minutes of applying the Healing Beat when tracking changes continuously over time. Could.

 As a result of measuring to check the effect of Healing Beat on heart rate, the experimental group significantly decreased from 15 minutes to 35 minutes after the experimental treatment compared to the control group. Particularly, when the heart rate was increased in the state exposed to the stress source, the point of recovery of the subject's stable heart rate was 20 minutes after applying the healing beat. On the other hand, the control group is a result that verifies that Healing Beat is effective in anxious situations exposed to a stress source by noticing that it did not recover to an initial heart rate even after 40 minutes in a stable state after exposure to the stress source.

In addition, in order to subjectively measure the degree of anxiety of the subject, the state anxiety was measured twice before and after the experimental treatment as a questionnaire, and the experimental group significantly decreased than the control group. The reason why the state anxiety was measured twice is that the questionnaire must be filled in every measurement, so the experimental group is applying the Healing Beat, the control group is not applying the Healing Beat, but it can be a limitation in measuring autonomic nerve balance and heart rate in a stable state. It was measured twice before and after the experimental treatment. State anxiety is a measure of the degree of anxiety a subject feels, and is considered to have a meaning different from the importance of an objective variable.

The results verified in this experiment may be similar to the experimental results of the anti-stress effect of listening to music in the past, but in this experiment, the objective and subjective data were measured when measuring variables to verify the relief of anxiety. In addition, in most existing music and stress-related experiments, only pre- and post-measurement measures were performed to confirm the anti-stress effect, and music intervention was limited to preferred music, relaxation music, and classical music. It is meaningful as an initial experiment that provides an effective clinical basis by tracking the temporal changes in order to grasp the point of recovery of stress and the part that Healing Beat was developed and applied in stress situations after measuring the average heart rate in.

In conclusion, Healing Beat appears to reduce anxiety in stressful situations and is effective in alleviating anxiety. Therefore, it can be used as a method to relieve stress in many clinical scenes exposed to various stress sources or in daily life. In addition, it is considered to be the basic data that can be applied to many subjects, such as patients with acute and chronic diseases. In addition, it can be used for effective nursing practice application as an initial experiment to check the recovery point according to the change of time after applying Healing Beat as well as theoretical and practical indicators according to the stability effect in a stressful situation.
