Cohort Study on Biomarkers and Clinical Treatment of Tinnitus

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical trial is to search for biomarkers in tinnitus patients in tinnitus patients and changes in biomarkers before and after treatment. The main questions it aims to answer are: What are the biomarkers of tinnitus patients？ How do these biomarkers change during treatment and is there a good correlation with behavioral outcomes? Participants will be asked to complete audiological examination, tinnitus assessment, and magnetoencephalography examination, and they will receive sound therapy or repetitive transcranial magnetic stimulation therapy.

Detailed Description
-----------------
This study aims to use magnetoencephalography (MEG) to collect the resting state responses before and after treatment in the control group, tinnitus patients in the acoustic stimulation treatment group, and rTMS treatment group. Firstly, compare the differences in power spectrum and brain functional connectivity indicators between tinnitus patients and normal control groups in different frequency bands, providing a theoretical basis for clinical diagnosis, precise positioning of tinnitus damaged areas, and understanding the pathogenesis of tinnitus; Secondly, compare the electrophysiological functional indicators of tinnitus patients before and after treatment to reveal whether the damaged brain network can gradually reshape after treatment, and whether network information can serve as potential biomarkers to indicate the degree of tinnitus recovery; Finally, compare the effectiveness differences between the two treatment methods, analyze their influencing factors, and provide guidance for frequency band precise intervention and rehabilitation of chronic tinnitus patients.
