Tinnitus is a sound that is subjectively perceived by the human ear in the absence of external acoustic or electrical stimulation. According to the statistical data of the United Kingdom and the United States, the incidence of tinnitus accounts for 15% to 20% of the total population. These patients are not only mentally distressed and irritable, but also affect their normal life and work. Tinnitus is usually found in middle-aged and elderly patients. However, in recent years, there is a trend of its onset being younger, and the number of white-collar workers coming to the clinic for tinnitus is increasing due to the high work pressure, fast-paced life and difficulty in ensuring sleep patterns and time. It is worth noting that tinnitus is an illusion that occurs in the auditory system and is a symptom rather than a disease. In severe cases, it can affect normal life and work. The sound of tinnitus can vary from one individual to another. Some people have tinnitus on one side of their ears, while others have tinnitus on both sides; some have it as a continuous cicada sound, some have it as a low “rumbling” or “buzzing” sound, and some have it as a high-pitched machine roar. In the case of severe tinnitus, it can continue throughout the day, seriously affecting the quality of life and work efficiency. In the case of mild tinnitus, it may occur occasionally during fatigue or sleep disorders, but it does not seem to be a serious problem.
