According to the survey, there are few research results on the prevalence of phobia that have been strictly tested by peers. To be precise, there is only one article, which is a paper entitled "Study on the Prevalence of Internet and Mail Phobia" written by Anderson and others, and published in the International Journal of Audiology in 2002 (4 1). Their research object is Swedish adults, and they conducted a questionnaire survey through the internet and mail: 1 167 people participated in the internet, among which 595 people responded to the questionnaire, reaching 51.9%; 987 questionnaires were mailed, and 589 people responded, reaching 59.7%. Excluding other factors, such as hearing loss, the prevalence of phobia through internet and email in normal people is 7.7% and 5.9%, respectively, while the prevalence of severe phobia is only 2-3% in the general population. According to Baguley and others' analysis, they think that the prevalence of phobia may be underestimated at present, but Andersson's data is consistent with Jastreboff's earlier judgment: the latter thinks that 4-5% of the general population suffers from severe tinnitus, and 40% of these severe tinnitus patients may suffer from phobia, accounting for about 2% of the general population.

It is worth noting that the other two studies on the prevalence of phobia are higher than Andersson's data, but these two studies are only published in the proceedings of academic conferences, lacking specific investigation details. One is the survey results published by Rubinstein et al. in Sweden in 1996: According to the random sampling survey of 36-year-old female subjects in 1023, the prevalence of phobia reached 23%; The other is the research conducted by Fabijanska and others in Poland from 65438 to 0999. Through the questionnaire survey of 10349 people, they reported that the prevalence rate was as high as 15.2%. In addition, in the study of children's tinnitus in 1995, Kapoors of Western Australia Hearing Center found that children could not sleep because of tinnitus. It is difficult for children to concentrate on their studies, and some of them suffer from phobia because of tinnitus.

If you look at the data of some people with special diseases, the prevalence of phobia is higher. As mentioned above, Jastreboff's research results show that 40% of tinnitus patients have phobia, Andersson and others found that 60% of tinnitus patients have phobia, and Dauman and others recently found that the prevalence of phobia among tinnitus patients is as high as 79%.

As far as the relationship between phobia and tinnitus is concerned, at least 86% of phobia patients are accompanied by tinnitus (Anari et al 1999). Studies have shown that tinnitus is often a precursor to phobia. For example, Andersson et al. found in the long-term follow-up experiments of 1999 to 200 1 that only 38% of patients with early tinnitus complained of phobia, but only 38% complained of phobia.

Research on phobias and other diseases continues. At present, some research results show that some diseases are related to phobia. For example, in 1990, Klein et al. investigated 65 patients with Williams syndrome and found that 95% of them suffered from phobia at the same time. The same result was further confirmed by Van Dorsel et al.' s experiment on 82 Dutch patients. In 1999 1997 (95%), Rosenhall et al. tested 199 autistic children and confirmed that 18% of them also had phobia. The phobia mentioned above is related to migraine. In 1995, Silberstein reported that the prevalence of phobia in migraine patients ranged from 60% to 100%.

Of course, when analyzing the prevalence of phobia, we must be aware of the particularity of this disease, except for some related diseases mentioned above, that is, most phobia patients have no other clinical symptoms. Therefore, we need to strengthen the detailed investigation of the patient's medical history and the full clinical examination and identification of phobia.

Distinguishing and distinguishing different terms of phobia and understanding the incidence of phobia will not only help to understand phobia, but also help to improve the understanding of tinnitus. More importantly, only in this way can we better prescribe the right medicine and formulate corresponding treatment plans for tinnitus and phobia. It is difficult for traditional tinnitus treatment methods to distinguish the characteristics of these different types of sound discomfort, which leads to poor treatment effect.
