A method and system for synthesizing tinnitus rehabilitation sound combining fractal and masking

Abstract

The invention discloses a method and system for synthesizing tinnitus rehabilitation sound based on the combination of fractal and masking. The scheme of the invention combines melody music with natural audio. The chord in the mode is used as the main track accompaniment; the natural audio is spliced ​​by the natural sound segment algorithm to form a natural sound accompaniment track. The connection between the natural sound segments is relatively reasonable, which can achieve a smooth transition and effectively solve the problem of directly connecting the fundamental tone segments. The problem of sound mutation at the connection. The tinnitus recovery sound synthesized by the scheme of the present invention can provide patients with comfortable background music, relieve the patient's irritability, and achieve a habituation effect. It can also match the patient's personality with natural music with the same frequency as his tinnitus, and has a masking effect.

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
