Embodiment Construction

[0035] Overall idea: the first problem to be solved in the present invention is to analyze the fluctuation characteristics of music, and the fluctuation characteristic value of music can be obtained more accurately through calculation. For a piece of music, there are many elements that can characterize its characteristics, such as the rhythm, mode, frequency, and musical instruments of the music. For this system, we pay more attention to the relationship between music and frequency. The overall block diagram is as figure 1 shown.

[0036] So the first thing is to analyze the spectral density of music, get the relationship between its power spectral density (PSD) and its frequency, and draw the relationship between the two into a graph, expressed in a log-log coordinate system. Afterwards, the data curve was fitted several times by the method of least squares, and the eigenvalues ​​were obtained from the fitted curve. Finally, find out the rules. Especially those pieces of ...

Abstract

The invention pertains to the field of therapeutic devices, which particularly relates to a music prescription quantification selective system basing on the power spectrum density eigenvalue. In order to provide psychological adjustment tools with deep potential, the technical proposal adopted by the invention is that: the music prescription quantification selective system basing on the power spectrum density eigenvalue comprises a power spectrum density analysis module , an establishing power spectrum density and frequency logarithm coordinates module, a curve fitting module, a music eigenvalue Beta value module, a collecting module to music document library, an output module carrying out music treatments in sequence, and also comprises a necessary music eigenvalue Beta value module obtained according to Beta equal to S-N, the necessary music eigenvalue Beta value module is output to the collecting module to music document library, S is the standard value in the most healthy state, and S is set as 1, and N is the present psychological health indicator of the curer. The music prescription quantification selective system is mainly used in personal psychotherapy and recuperation.

Description

technical field [0001] The invention belongs to the field of therapeutic equipment, and in particular relates to a music prescription quantitative selection system based on power spectral density characteristic values. Background technique [0002] Music is used as a means of psychological adjustment, not only to attract and divert people's attention, but also to divert the excitement of the cerebral cortex, so that some parts of the cerebral cortex enter an excited state, and in turn inhibit the excitement of another part of the cortex, so that A person's mental state is transformed. With this function, music can attract people's excitement into positive consciousness and emotion, and strengthen, enrich and enrich it, and transform it into so-called spiritual power. The system designed in the present invention can select music with appropriate characteristic values ​​according to the data formed after quantifying emotions, and make various music prescriptions. These music ...
