Is it a brain problem that you can t hear clearly?

1. In layman's terms, it is the brain, not the ear, that processes auditory signals, so poor hearing and poor discrimination can of course be regarded as a "problem" in the brain, but the so-called "problem" obviously cannot be compared with brain tumors, brain inflammation or mental retardation. Brain tumors (such as acoustic neuroma) and intracranial infections can affect hearing. Mental retardation due to developmental disabilities can also lead to hearing impairment, but the problems we are talking about are not from this perspective.

Normal hearing should involve two aspects of ability: not only to hear, but also to hear clearly. Otherwise, communication cannot proceed properly.

If you can hear clearly, you must hear it, but if you can hear it, you may not hear it clearly. This suggests that the latter is a more advanced activity of the nervous system.

2. For the identification of deafness, we have been accustomed to relying on pure tone audiogram. A pure-tone audiogram can clearly tell us the degree of hearing loss (average hearing loss) and reflect a decrease in the patient's auditory sensitivity (hearing acuity), or a decrease in the patient's ability to perceive the size of sound. But a pure-tone audiogram does not tell us how well a patient can hear or discriminate.

In fact, any deafness will involve two aspects of hearing sensitivity and resolution, some people lose more than the ability to distinguish, some people lose less. In a noisy environment, people with normal hearing cannot hear clearly because the signal itself becomes ambiguous; A similar situation can occur when the signal is too quiet. For example, the TV is too quiet for us to hear.

But that's not the whole problem. The inner ear has the ability to analyze acoustic signals at a rudimentary level. When the inner ear is damaged, the ability to analyze auditory perception is significantly reduced.

But since our auditory ability has enough leeway, 70% of it is enough to ensure that we can hear clearly, not 100%. Therefore, less severe inner ear damage does not cause the patient to completely lose hearing and discrimination.

3. The auditory center has more important ability to analyze acoustic signals. If the auditory center is damaged, the auditory discrimination will be worse. Therefore, if you can't hear (or the sound is too quiet), you will definitely not be able to hear clearly; But even if you hear it, you will still not be able to hear clearly due to the decline in the analysis ability of the inner ear and auditory center.

Moreover, this problem is difficult to solve. Patients with presbycusis may have impairments in memory, attention, and observation ability, which is a comprehensive manifestation of functional deterioration, not the inevitable result of deafness. In recent years, the hot topic of senile dementia is related to hearing impairment?

I'm afraid there is no direct relationship. However, the reduction of auditory stimulation due to deafness may worsen the severity of Alzheimer's disease.

It is necessary to determine whether it is a problem with the low resolution of the patient.

Different parts of the cochlea correspond to different frequencies. When the outer hair cells are damaged or necrotic, the cochlea partially loses its ability to select frequencies, and the effect of this defect is that when the frequencies of speech components and noise are different but very close to each other, the cochlea will have only one broad functional area excitation. As a result, the brain is unable to separate speech signals from noise.

You can first confirm the need for hearing aids and then consult a professional to provide hearing recovery training.

In layman's terms, it is the brain, not the ear, that processes auditory signals, so poor hearing and poor discrimination can of course be considered as a "problem" with the brain. Otherwise, communication cannot proceed properly.

If you can hear clearly, you must hear it, but if you can hear it, you may not hear it clearly. This suggests that the latter is a more advanced activity of the nervous system. For the identification of deafness, we (including the doctors in the hospital) have become accustomed to relying on a pure tone audiogram.

A pure-tone audiogram can clearly tell us the degree of hearing loss (average hearing loss) and reflect a decrease in the patient's auditory sensitivity (hearing acuity), or a decrease in the patient's ability to perceive the size of sound.

Hello, hearing clearly is considered to be hearing loss. Depending on how long hearing loss has occurred, it is divided into sudden deafness and progressive deafness. Sudden hearing loss is a sudden onset of hearing loss, mostly sensorineural hearing loss, most of which are of unknown origin.

Progressive deafness refers to hearing loss that occurs gradually and gradually worsens, and there may be organic lesions in the ear, such as chronic purulent otitis media, Meniere's disease, etc. Ancillary tests for deafness include otoacoustic emissions, pure-tone hearing threshold testing, and acoustic impedance. Once the disease is discovered, it needs to be ** as soon as possible, and the commonly used drugs are drugs that nourish the nerve, vasodilators, etc., and the hyperbaric oxygen chamber has a certain effect on improving the microcirculation of the inner ear.

Combined with traditional Chinese medicine, acupuncture, acupuncture point injection, etc., good results can be obtained. First: Hearing impairmentUnder normal circumstances, our hearing is able to distinguish hundreds of thousands of subtle differences in sounds.

Once an obstacle arises, the problem is more serious than you think. If you can't hear the horn of a car clearly, you are prone to traffic accidents; If you can't hear a knock on the door, you don't know that a guest is coming; If you can't hear the ** sound, you can't exchange information with relatives and friends; If you can't hear it clearly when you watch TV, you can't understand the cause and effect. It's also important to note that not being able to hear can make us feel insecure.

For example, when walking at night, a slightly louder sound can alert us, but too much silence can make us extremely nervous and feel more insecure.

Second: the problem of communication disorder deafness is more of a communication problem, and the harm of deafness is more of a harm derived from communication disorder. Hearing impairment in adults can lead to communication failures, interruptions, misunderstandings, repetitions, and non-answering questions.

Our understanding of the surrounding environment, the understanding of social and even the changes in the world is achieved through verbal communication, once deaf and communication barriers, patients will gradually be isolated from society, like being encased in a glass bottle, able to see the outside world but unable to communicate with the outside world.

Deafness can also cause Alzheimer's disease, which seriously affects their health and quality of life, so we must be vigilant to prevent, detect and intervene as soon as possible.

, the ear is hard to hear, and hearing loss can occur. Hearing loss can be divided into sudden hearing loss and progressive hearing loss. Sudden hearing lossSudden hearing loss is mostly sensorineural hearing loss, mostly unexplained. Progressive deafness refers to progressive hearing loss.

Hearing loss can occur, so go get your hearing checked.

If we talk at a normal speech volume, communication is barrier-free for us normal people, but a patient with a hearing loss of about 60 decibels may not be able to hear what is being said, and even the words that are pronounced softly cannot be heard. So the patient wears a hearing aid, do.

Yes, hearing and hearing clearly are two different concepts.

Hearing is done by the entire auditory system. In addition to the outer ear, middle ear, and inner ear, it also includes the auditory nerve, auditory channel, and cortical auditory area. Together, we call the latter two the listening center.

What can be seen must be seen, but what can be seen may not be seen clearly; In the same way, what can be heard must be heard, and what can be heard may not be heard. Hearing is a basic function of the auditory system, while hearing is a more advanced function. Only when the clap is closed must have a signal transmitted to the listening center, we will "hear"; But to hear clearly, you must also have auditory discrimination.

The listening center has the ability to analyze the acoustic signal more importantly. The auditory center is impaired, and the auditory discrimination is even worse. There is a type of deafness caused by a central disorder called central deafness.

A typical central deaf patient can hear voices quietly, even very small ones, but he can't understand or hear clearly. Obviously, if you can't hear it (or if it's too quiet), you won't be able to hear it clearly; However, even if you hear it, you will still not be able to hear clearly due to the decline in the analytical ability of the inner ear and auditory center. Moreover, this problem is difficult to solve.

We can also reason the other way around: damage to the inner ear or the auditory center is the main cause of hard hearing. Unfortunately, most people with neural hearing loss have damage to their inner ear and auditory center, but to varying degrees.

Therefore, many patients with neurological hearing loss will complain that they can hear but cannot hear clearly.
