Why is my eardrum normal or I can t hear clearly?

Ordinary people call it "eardrums". "Tympanic membrane" is a professional term for doctors, and in the minds of many people, the eardrum is the most important part of the auditory system. If you have a problem with your eardrum, you will become deaf, and if you have a normal eardrum, you should not have a hearing problem.

Therefore, some patients often wonder: why are they deaf when the doctor's examination proves that the eardrum is normal? Even I am very worried about the invagination of the eardrum that occurs when people with normal hearing suffer from colds, and I believe that the inversion of the eardrum will inevitably lead to severe hearing loss.

In fact, in the human auditory system, the eardrum, despite its importance, plays only a "small role". The main function of the eardrum is to transmit external acoustic signals to the inner ear in an appropriate way. In addition, the eardrum also has the ability to amplify sound signals, which is about Although it is a lot, it is not a big problem for people with normal hearing, and it is not even noticeable.

Some of them preceded it.

In patients with poor fertility, the pinna, external auditory canal, and middle ear are not developed at all, and the hearing loss is only about 60db, which is not very severe in terms of deafness. It can be seen that the role of the eardrum is smaller than people think. More important in the auditory system is the inner ear and the central part of the auditory part behind it.

Something goes wrong with these parts, which we call sensorineural hearing loss. Patients with sensorineural hearing loss may not only be unable to hear small sounds, but also have problems such as poor auditory discrimination and revival. Also, the degree of hearing loss is more severe.

Therefore, a normal eardrum can also cause deafness, and it may be more severe.

Deafness can also occur with a normal eardrum, and may be more severe --- sensorineural hearing loss.

TinnitusIn the case of hearing loss, the brain is unable to accept certain frequencies of sound, and the brain begins to adapt, and tinnitus may be a way for the brain to fill this gap.

Middle ear blockage or Eustachian tube dysfunction.

Blockage of the ear canal can lead to increased pressure in the inner ear, affecting the function of the eardrum. Nixin such as excessive earwax, middle ear effusion, etc. The eustachian tube is abnormally open, which can cause tinnitus similar to the roar of the ocean, and the frequency is synchronized with the breathing of the ruined mu.

Head and neck trauma.

Severe trauma to the head or neck can damage nerves, blood flow and muscles, causing tinnitus. This tinnitus symptom tends to be severe.

Temporomandibular joint disorders.

The temporomandibular joint, which connects the mandible to the skull, is located at the front of the ear and controls movements such as opening, closing, or chewing.

Damage to the muscles, ligaments, articular cartilage in the temporomandibular joint, can cause tinnitus symptoms because it is adjacent to the auditory system and shares part of the ligaments and nerves with the middle ear. In this type of tinnitus, patients may also feel jaw pain or have limited jaw movement; When chewing or speaking, there are fricatives.

Generally, the eardrum of the vibration of the object resonates and then conducts the auditory nerve to hear the sound.

Let's get on the fire, see Chinese medicine to recuperate.

It could be something else.

When the tympanic membrane is perforated for various reasons, the lack of sound pressure amplification and pressurization can lead to hearing loss.

For hearing, the eardrum does not play as much of a role as people think. The tympanic membrane is of great significance in the transmission of sound, the amplification of signals, and the protection of deep auditory organs from invasion. The most obvious example is that once the eardrum is perforated, it is possible for pathogenic bacteria to enter the middle ear through the perforation, causing inflammation of the middle ear.

Once the inflammation of the middle ear occurs, it is not easy to do it, and it often reverses, and in severe cases, pathogenic bacteria will break into the brain and harm the central nervous system.

Sounds can be heard. If the injury is severe, the inner ear may also lose hearing. It is generally said that sound can be heard simply if the eardrum is ruptured, but the hearing is reduced. However, not paying attention can lead to chronic otitis media, so it is still necessary to be timely**.

The eardrum has the effect of amplifying sound and protecting the inner ear. When the eardrum ruptures, the energy of the transmitted sound decreases due to the loss of amplification, resulting in a decrease in the loudness of the voice. Amplification of sound by tympanic membrane repair is not fully restored; However, the barrier effect can be restored, and bacteria can be prevented from entering the middle ear, causing the onset of inflammation such as otitis media.

There are many factors that can cause hearing loss, but it is not necessarily caused by a ruptured eardrum.

Hello: First of all, we have to be clear about 1The ear is composed of three parts: the outer ear, the middle ear, and the inner ear, the tympanic membrane is only a part of the middle ear, and the tympanic membrane is located between the outer ear and the middle ear, separating the two of them; At the same time, it protects the middle ear from substances present in the external auditory canal and enters the middle ear; 3 The tympanic membrane is only one link in the sound transmission pathway, and the complete air transmission to the sound pathway is:

Sound waves-auricle-external auditory canal-tympanic membrane-ossicular chain-cochlea-auditory nerve-auditory center.

Therefore, if the eardrum is intact, hearing loss may be caused by problems with other parts of the middle ear or the middle ear.

I hope my answer is helpful to you, if you do have a hearing impairment, please go to the hospital.

Hello, hearing loss Will my hearing recover after tympanic membrane repair surgery? There are many types of hearing loss, if it is a hearing loss caused by a perforated eardrum, after tympanic membrane repair surgery, the hearing will be restored to a certain extent, but if the hearing is not fully restored and communication is difficult, it is recommended to wear hearing aids. I hope my answer can help you.

If the tympanic membrane is not infected, it will only cause mild hearing loss, and the cause of hearing loss is not only the cause of the outer ear or eardrum, but also the hearing loss caused by the middle ear or the inner ear.

The eardrum is only a part of the auditory system, and its main role is to transmit sound signals of different frequencies from the outside world to the inner ear part of our auditory system in an appropriate way. If the eardrum is perforated, it will not be a big obstacle for people with normal hearing, and there may even be cases where it cannot be detected.

Hearing clearly depends on the proper function of the inner ear and auditory center in the auditory system. If there is a problem with these parts, not only the small sounds cannot be heard, but also the symptoms of poor hearing discrimination, inaudible sounds, very afraid of noise, or uncomfortable to hear loud sounds.
