Problems solved by technology

However, the natural sound is generally a short and repetitive sound, and the sound of repeated cycles is not effective in the treatment of tinnitus. Therefore, the application of natural sound in tinnitus rehabilitation is further limited.

preparation example Construction

[0028] refer to Figure 1-2 Shown, a kind of tinnitus rehabilitation sound synthesis method based on IFS fractal algorithm comprises the following steps:

[0029] S1. Select pitch audio

[0030] As a preferred embodiment, the pitch audio is selected to be consistent with the tinnitus matching sound of the tinnitus patient or the natural sound audio that the tinnitus patient likes. The natural sounds described in this embodiment include non-artificial sounds produced in nature, for example, the sound of running water, wind, birdsong, cicadas and the like. Since the natural sound matches the tinnitus sound of most tinnitus patients, the natural sound as a therapeutic sound can make the tinnitus patients feel the similar situation of tinnitus in the natural sound but not so fearful, so it can relieve the patient from the psychological level. The negative perception of tinnitus eventually achieves the effect of habituation. Further, in combination with the characteristics of di...

Embodiment approach

[0052] First, the IFS fractal sequence obtained after initialization is subjected to modulus transformation (i.e. modulo, amplification, and rounding processing on the fractal sequence) to obtain a fractal integer sequence; preferably, the fractal sequence obtained due to different fractal algorithms or different initializations The numerical value of is quite different, therefore, the value range can be judged first for the IFS fractal sequence obtained after initialization, and then the modulus value transformation can be performed on the selected range;

[0053] Secondly, according to the interval span of the fractal integer sequence (the difference between the maximum value and the minimum value), the fractal integer sequence is divided into intervals corresponding to the number of audios in the audio library;

[0054] Finally, the audio number mapping is completed through the interval judgment of the sequence value, and the fractal natural sound audio is finally synthesize...

Abstract

The invention discloses a method of synthesizing tinnitus rehabilitation tone based on IFS fractal algorithm, and the method comprises the steps of selecting fundamental tone audio frequency; then transforming the fundamental tone audio frequency to generate multiple transformed audio frequencies; finally generating a fractal sequence by an IFS iteration system and mapping the sequence value to a corresponding basic audio frequency and a transformed audio frequency, thereby synthesizing the tinnitus rehabilitation tone audio frequency. According to the method, a specific audio frequency fragment is transformed according to rhythm to generate an abundant tone database, and the fractal algorithm is introduced in the synthesis of dynamic natural tones; the hierarchy change of the fractal image is expressed in the natural tone, so that the repetition of acoustic treatment tone and self-similarity are prevented, and the basic characteristics of tinnitus rehabilitation tone are insisted.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for synthesizing tinnitus rehabilitation sounds based on an IFS fractal algorithm. Background technique [0002] Tinnitus is a subjective auditory perception without external sound source stimulation, which is very common in clinical practice. Sound-based sound therapy is recognized as having general applicability for the treatment of different types of tinnitus. This method mainly makes the incomplete masking of tinnitus, and uses a sound as the background sound, so that the patient gradually gets used to the existence of tinnitus. Music-based sound therapy has been shown to be effective in relieving tinnitus symptoms in the short term, with the aim of promoting relaxation and regulating the patient's mood. However, studies have shown that once the music is played repeatedly, it will wake up the patient's memory and fail to achieve the expected relaxation and decompr...
