According to statistics, about 20% of the population is suffering from tinnitus. The incidence of tinnitus in people over 60 years old is as high as 30%. More than 80% of tinnitus cases are related to hearing changes. Other diseases that can cause tinnitus include head and neck trauma, systemic metabolic and endocrine system diseases, and a few tinnitus cases have no clear cause.

Tinnitus is a sound perceived when there is no external sound source. It can be one or two ears, and most of them are subjective tinnitus. That is to say, only tinnitus patients can hear “buzzing”, “squeaking” and other sounds, but others cannot perceive them. This kind of tinnitus, which can only be felt by oneself, affects people’s work and life to some extent, and even brings extreme negative effects such as anxiety, depression and suicide.

There are two kinds of non drug therapy for tinnitus

1. Tinnitus acclimatization treatment, i.e. do not change tinnitus, but change the response and attitude of tinnitus patients to their tinnitus, psychological consultation, etc., adjust the mentality and mood of patients, so as to reduce the annoyance caused by tinnitus. However, due to the long treatment time and high price, it is limited in clinical practice.

2. Tinnitus masking therapy, also known as tinnitus voice therapy, aims to use the external voice to inhibit the spontaneous excitatory activity of the cochlea or auditory nerve. Hearing loss with tinnitus patients wearing hearing aids is the application of this principle, that is, amplifying the surrounding sound, patients feel their tinnitus decreased.

Why is hearing aid useful to improve tinnitus?

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Many tinnitus patients will reflect that they feel the tinnitus is very loud in quiet environment, especially in quiet night, so tinnitus patients often complain that tinnitus is too noisy to sleep. But in noisy environment, tinnitus patients do not pay attention to tinnitus, and feel that tinnitus seems to “disappear”. In fact, in the noisy environment, tinnitus still exists, but it is hidden by the natural noise of the outside world.

Hearing aids can alleviate tinnitus symptoms based on the similar principle. By amplifying the external sound, the ambient sound can partially or completely mask tinnitus, and then relieve tinnitus. When the patients hear the environmental sound higher than their hearing threshold, the resolution of their nervous system to tinnitus and environmental sound will gradually reduce, so as to achieve the effect of increasing treatment.

The treatment of tinnitus with hearing aid is similar to a kind of tinnitus masking therapy. Tinnitus masking therapy is a popular acoustic therapy, which uses narrow band noise close to tinnitus frequency to mask tinnitus, so as to achieve the purpose of treatment and rehabilitation.

In order to make the masking sound play an ideal masking role, we must have enough loudness, and the hearing aid is to enlarge the loudness according to the hearing loss of the patients with hearing loss. The loudness is large enough, which can well mask tinnitus and achieve the effect of improving tinnitus.

Many patients have bilateral tinnitus, and both sides have the same frequency. Because of the strict frequency distribution of peripheral auditory pathway, the probability of bilateral peripheral auditory pathway at the same time in the same place is very low, so almost all the tinnitus of the same frequency on both sides are central tinnitus. However, if the patients with bilateral tinnitus only wear one side hearing aid, it will only inhibit the tinnitus on the same side, but not on the other side. This phenomenon is consistent with the phenomenon of hearing deprivation. Therefore, bilateral hearing loss is accompanied by bilateral tinnitus. It is better to wear hearing aids on both sides, which can not only overcome the phenomenon of hearing deprivation, but also effectively inhibit tinnitus.

The effect of hearing aids on tinnitus is actually based on the principle of sound therapy. After wearing the hearing aids, the sound that can be heard is loud and rich, and the tinnitus sound is naturally less obvious. Patients don’t feel tinnitus, so they are not so anxious, which is also helpful to suppress tinnitus. In such a virtuous circle, tinnitus will gradually disappear.
