Description
Technical field
The present invention relates to a kind of adaptive heart sound hypnosis music generating methods based on heart sound control.
Background technique
With the continuous development of science and technology, the music psychology based on the theories of psychology and behaviour therapy gradually develop to fortune
With the multi-disciplinary comprehensive application technology such as acoustics, physics, biology, psychology, signal processing, medicine, createed polymorphic type,
The musical therapy method of diversification.
Excellent melody can adjust mood, allow people to loosen, keeping tensions down state.Listened before sleep it is some it is tuneful,
The melodious sleep music of lively rhythm, harmony truly has benefit for sleep.
When ear receives musical sound, regular rhythm can be transmitted to brain, the vibration frequency of brain can therewith with this
Stimulation, which generates, mutually draws effect, can be with exciting human when music rhythm progressively reaches harmonious resonance with brain sleep rhythm
Potential adjusts the micro-vibration activity of body interior, into ortho physiological status.
Such regular movements is created in intracerebral, have such rhythm and pace of moving things wave, such as the beat in music in the music that needs to sleep,
Rhythmic fluctuation in natural speech, especially human body heart sound itself are possessed rhythmic and to the height from mother heart sound
Degree trust property, dependence, can more allow hearer's soul to loosen calmness, allow music rhythm and brain sleep rhythm to be rapidly achieved harmonious total
Vibration allows pleasant idea to substitute the tight state of mind to promote to sleep.
Summary of the invention
The purpose of the present invention is: be based on modern control theory and music modulation technique, propose it is a kind of based on heart sound control
Adaptive heart sound hypnosis music generating method.
It is of the present invention to the effect that how to be compared the sleep heart sound of user with deep sleep heart sound, make
The rhythm and pace of moving things of analog sleeping heart sound, intensity, the ratio of frequency content and aliasing background music change in real time, obtain a kind of dynamic
Heart sound sleep music, user is slept music by listening to heart sound, allow current music rhythm to adjust the current rhythm of brain,
And heart sound sleep music is constantly adjusted by feedback control means, gradually the rhythm of brain is guided to force to brain sleep rhythm.It is real
Current heart sound modulation sleep music gradually guides user to enter sleep shape to generate adaptive dynamic heart sound sleep music
State.
Specifically, the method that the present invention uses is as follows:
Step 1, the current sleep heart sound for acquiring user in real time by heart sound transducer；
The deep sleep heart sound obtained is compared, the difference of acquisition by step 2 by controller with current sleep heart sound
Xor signal is as feedback quantity；
Feedback quantity is sent to controller by step 3, is controlled hypnosis heart sound generator according to the size of feedback quantity, is made the hypnosis heart
The rhythm and pace of moving things of sound, intensity change in real time, and produce adaptive heart sound with hypnosis music mix by music synthesizer and urge
Dormancy music.
Step 4, user listen to new heart sound hypnosis music in quiet environment, allow current music rhythm to adjust and listen to
The current rhythm of person's brain, body and mind loosen, and the micro-vibration activity of body interior is slowed down, and cardiomotility is also slowed down, and is stepped into just
Normal sleep physiology state, it is corresponding to produce corresponding sleep heart sound.
Step 5 after the time for being spaced 3~5 minutes, acquires current sleep heart sound, step 2 is repeated, and if deep sleep
The difference of heart sound levels off to zero, shows to enter brain sleep rhythm, can gradually weaken heart sound hypnosis music until stopping.Otherwise it weighs
Multiple step 3, is forced eventually by the rhythm that feedback control means gradually guide brain current to brain sleep rhythm.
In order to use difference signal as feedback quantity go control hypnosis heart sound the rhythm and pace of moving things, intensity and frequency content, it is described
Hypnosis heart sound is a kind of emulation synthesis heart sound；The model of the hypnosis heart sound generator includes: caused by right side of heart activity
Right side hypnosis heart sound, the generated left side hypnosis heart sound of left side activity, this two parts, which is superimposed, synthesizes hypnosis heart sound,
That is:
Wherein, r represents cardiechema signals caused by right side of heart activity, and the dynamic trajectory of right side hypnosis heart sound is by as follows
What three ODEs generated:
L represents cardiechema signals caused by left side of heart activity, and the dynamic trajectory of left side hypnosis heart sound is by following three
What ODE generated:
In equation (2) and equation (3), ω is the angular speed that track surrounds limitation ring rotation, it and cardiac cycle RRnHave
It closes:
Wherein:
θ=arctan (y, x) ∈ [- π, π]
θ is related to discrete time t, and can indicate are as follows:
And have:
θkDetermine the initial time of electrocardiosignal needle position misalignment,Determine the initial time of cardiechema signals needle position misalignment
(start time of S1 and S2).δθkIt is a positive offset, equation (5) shows the relationship of heart sound waveform and ecg wave form,
In fact, it reflects temporal delay of the cardiechema signals with respect to electrocardiosignal.
Modulated sinusoidal component in equation (2) and equation (3)It is indicated:
Wherein, vibration frequencyIt isLinear decrease function, initial value isThe index of modulation at left and right sides of heartIt is slightly different,Cause heart sound needle position misalignment, to generate waveform.
ParameterWithAmplitude and the duration of needle position misalignment are controlled, they are the key that determine synthesis hypnosis heart sound ginseng
Number.
Compared with prior art, the invention has the following advantages:
(1) user is continued to monitor heart sound interval time, constantly to heart sound sleep music while support vectoring is slept
Real-time monitoring promotes sleeper effect good, fast speed.
(2) monitoring sleep heart sound controls hypnosis heart sound generator, makes the rhythm and pace of moving things, intensity and the frequency content of hypnosis heart sound certainly
Adaptation changes.
(3) low to running environment and equipment requirement degree of dependence.
Detailed description of the invention
Fig. 1 is a kind of control flow signal of the adaptive heart sound hypnosis music generating method based on heart sound control of the present invention
Figure.
Fig. 2 simulates hypnosis heart sound waveform diagram.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
The specific embodiment of the present invention is as shown in Fig. 1.
By acquiring the current sleep heart sound of user and being compared it with deep sleep heart sound, make hypnosis heart sound
The rhythm and pace of moving things, intensity, the ratio of frequency content and aliasing background music change in real time, obtain a kind of dynamic heart sound hypnosis sound
Happy, user allows current music rhythm to adjust the current rhythm of brain, and pass through feedback control by listening to heart sound hypnosis music
Means processed constantly adjust heart sound hypnosis music, gradually the rhythm of brain are guided to force to brain sleep rhythm.Realize motive sound control system
Hypnosis music gradually guides user to enter sleep state to generate adaptive dynamic heart sound hypnosis music.
Specifically, the present embodiment the following steps are included:
Step 1, the current sleep heart sound for acquiring user in real time by heart sound transducer；
The deep sleep heart sound obtained is compared, the difference of acquisition by step 2 by controller with current sleep heart sound
