What are the causes of hearing hypersensitivity?How to distinguish hearing allergy?

    Regarding the term “allergies”, what we hear most is skin allergies, pollen allergies, food allergies, etc., but there is another kind of allergy that does exist, that is, hearing allergies.The patient’s tolerance to normal sounds will decrease, and they will feel resistance and discomfort to certain sounds. Hearing hypersensitivity can cause hearing damage, and severely may cause hearing disorders and other diseases.

    We still have to spend some time to understand that the pathogenesis of hyperacusis is still not very clear, and it is still unclear whether it is a staged manifestation of hearing loss or an independent disease.
Clinical diagnosis is mainly based on the patient’s symptoms. For example, a patient once described: If someone has a loud voice during a conversation, both ears will feel tight, tinnitus appears and headaches, and it will not recover until at least 10 minutes before hearing a sudden sound. (Not necessarily very loud), there will be a startle reaction, the heartbeat will increase, and it will take about 5 to 10 minutes to calm down gradually.


There are many diseases that may be complicated by this symptom:

1. The most frequently mentioned is tinnitus. The so-called subjective idiopathic tinnitus generally refers to hearing sounds of unknown origin from one’s head, which is a kind of illusory auditory cognition.Due to the increased gain of the central auditory system, silence becomes sound, and tinnitus is felt. Some people think that hyperacusis is the predecessor of this kind of tinnitus, and the two are related.

2. Eustachian tube patency: The eustachian tube is incompletely closed, the middle ear cavity and the nasopharynx are connected, the resonance cavity becomes larger, and there is earplugs, and the sound sounds reverberant. The so-called “self-hearing enhancement” phenomenon occurs. Patients often complain of hyperacusis .

3. Facial nerve palsy: It is generally caused by a virus infection. If the disease affects the nerve branches that innervate the stapedius muscle, causing abnormal auditory reflexes, auditory hypersensitivity will occur.

4. In the surgical treatment of otosclerosis, the stapes tendon must be cut off, the auditory reflex disappears after the operation, and auditory hypersensitivity may also occur.

5. Lymph fluid outside the labyrinth of the inner ear seeps into the middle ear cavity, and the inner ear presents relative endolymphatic hydrops, which makes it harder to tolerate loud sounds.

6. Meniere’s disease, idiopathic endolymphedema of the labyrinth of the inner ear, fear of loud voices is common in the early stage of the disease.

7. In cases of severe deafness caused by damage to the labyrinth of the inner ear, in addition to hearing impairment, they often complain that it is very uncomfortable to hear sharp sounds.

8. Migraine: Whether with or without aura, that is, typical or common headache, symptoms such as fear of noise and noise usually occur.

9. In mental disorders, such as depression or panic disorder, patients often have hyperacusis or fear of sound.

10. Autism: A child with autism may not be able to hear some sounds, but is particularly sensitive to some sounds (hearing distortion), he will hear the sound of water pipes on the wall, or the sound of toilet flushing upstairs very clearly , When it rains, the raindrops become thunderous and so on.Some people even don’t like to listen to the voice, so they don’t want to speak, making it difficult to learn the language.


At present, the mainstream method for hearing hypersensitivity can be adopted, which is to adopt tinnitus habit therapy. At first, it was used to treat tinnitus. Later, it was discovered that this method also has a very good effect on the treatment of allergy sufferers. However, the name of this method is called sound. Sensitive, general patients can go to the website to please the correct way for some things.


How to distinguish hearing hypersensitivity_ what symptoms are easily confused with hearing hypersensitivity?


Auditory hypersensitivity means that the tensor tympanic membrane that keeps the tympanic membrane tense is innervated by the inner pterygoid nerve of the trigeminal nerve branch, and the stapedius muscle is innervated by the facial nerve. These two muscles are in an antagonistic relationship to maintain balance.When the facial nerve is paralyzed, the stapedius muscle is paralyzed. As a result, the tensor tympanic membrane is relatively tense, the tympanic membrane is high, and small sounds produce strong vibrations, which can cause auditory hypersensitivity, which is seen in the lesions of the facial nerve above the stapedius branch.Tinnitus is a disorder of auditory function, and it is also the response of the auditory analyzer to appropriate and inappropriate stimuli.Tinnitus can be intermittent and persistent.There are multiple performances such as single frequency narrowband noise or white noise.Caused by ear lesions often coexist with deafness or dizziness.Caused by other factors, it may not be accompanied by deafness or dizziness.
