Fractal and masking combined tinnitus rehabilitation sound synthesis method and system

Abstract

The invention discloses a fractal and masking combined tinnitus rehabilitation sound synthesis method and system. The method comprises the steps of: combining melody music with natural audio, enablingthe melody music to map in-tone notes through an IFS fractal algorithm to synthesize a main sound track, and enabling an in-tone chord to serve as the accompaniment of the main sound track; and splicing natural audios by using a natural sound fragment algorithm to form a natural sound accompaniment track. The natural sound fragments are connected reasonably, smooth transition can be realized, andthe problem of sudden change of sound at the audio connection part due to direct connection of fundamental sound fragments at present is effectively solved. The tinnitus rehabilitation sound synthesized by the scheme of the invention can provide comfortable background music for a patient, relieve the irritable mood of the patient and play a role in the curative effect of acclimatization. The patient can be personally matched with natural music with the same tinnitus frequency, and the masking curative effect is achieved.

Description

technical field [0001] The invention relates to the technical field of tinnitus rehabilitation sound synthesis, in particular to a method and system for synthesizing a soothing tinnitus masking rehabilitation sound by combining the specific frequency characteristics of masking therapy and the soothing characteristics of habituation therapy. Background technique [0002] Tinnitus is an auditory perception that produces no external sound source in the brain or in the brain, which can seriously affect the patient's mood and interfere with the patient's daily life. Because the pathogenesis of tinnitus cannot be confirmed, there is no cure for tinnitus. The treatment of tinnitus is still being explored, and sound therapy is currently considered to be the most harmless and effective treatment. Sound therapy can be divided into habit therapy and masking therapy. Acclimatization therapy is to use background music that is lower than the loudness of the patient's tinnitus so that th...

AI Technical Summary

Problems solved by technology

[0003] Soothing fractal music can be used in habituation therapy, but the current fractal music mainly maps the notes in the middle range of MIDI directly to the main track, without considering the harmony and audibility of the notes

Moreover, the rhythm of the music is relatively chaotic, which makes the synthesized music have problems such as sudden changes in pitch and insufficient soothing

The sound source of masking therapy is usually white noise, etc. Prolonged noise stimulation can easily make the listener feel irritable, which is even more unfavorable for the treatment of tinnitus

When using the natural sound bank to synthesize the masking track, there are problems such as sound mutation at the audio connection when directly connecting the pitch segments
