Normal hearing should include two aspects of ability: not only hearing, but also hearing clearly. Otherwise, communication cannot proceed normally. If you can hear clearly, you must have heard it, but if you can hear it, you must not hear it clearly. This shows that the latter is a more advanced nervous system activity.

What should I do if I can’t hear clearly?

If you have difficulty hearing, you should go to the hospital for examination in time. A specialist doctor will conduct a preliminary examination and complete some related auxiliary examinations, such as pure tone audiometry and acoustic impedance, auditory brainstem response or mastoid CT, etc., in order to make a correct judgment. If the hearing loss is caused by cerumen embolism in the external auditory canal, the cerumen in the external auditory canal can be cleaned, and the hearing will improve after cleaning; otitis media and tympanic membrane perforation may also cause hearing loss, and specific analysis and treatment must be carried out according to the situation. For acute inflammation Patients can be treated with antibiotics, and some stable patients who are suitable for surgery can undergo breast surgery. For other hearing loss caused by inner ear diseases, such as presbycusis, sudden deafness, Meniere's disease, etc., treatment should be given to improve circulation and nourish nerves, and different treatment methods should be selected according to different reasons.

For the determination of hearing, we (including doctors in hospitals) have become accustomed to relying on pure tone audiograms. Pure tone audiogram can clearly tell us the patient's degree of hearing loss (average hearing loss), which reflects the decline in the patient's auditory sensitivity (auditory acuity), or represents the patient's decline in the patient's ability to perceive sound loudness. But the pure tone audiogram does not tell us how good or bad the patient's auditory discrimination ability is. In fact, any kind of deafness will involve problems in both hearing sensitivity and resolution ability. Some people have more loss of resolution ability, and some people have only less loss.

In an environment that is too noisy, the signal itself becomes unclear, and people with normal hearing cannot hear it clearly; the signal sound is too small, which may also cause similar situation. For example, the sound of the TV is too low and we can’t hear it clearly. But that's not the whole story.

The inner ear has rudimentary acoustic signal analysis capabilities. After the inner ear is damaged, auditory analysis ability will be significantly reduced. But since our auditory discrimination ability has enough room, 70% is enough to ensure that we can hear clearly, not 100%. Therefore, less seriousDamage to the inner ear may not completely cause the patient to lose hearing ability.

The hearing center has a more important ability to analyze sound signals. If the hearing center is damaged, auditory discrimination ability will be worse.

Therefore, if you cannot hear (or the sound is too low), 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 the auditory center. Moreover, this problem is difficult to solve.

We can also reason the other way around: damage to the inner ear or/and the auditory center is the main cause of unclear hearing. Unfortunately, most patients with sensorineural deafness have damage to the inner ear and hearing center, but the degree varies. Therefore, most patients with sensorineural deafness complain that they can hear but cannot hear clearly.

It is recommended that once hearing loss is discovered, timely intervention and wearing appropriate hearing aids can reduce the impact of hearing loss on our speech recognition ability. However, currently in China The current situation of hearing rehabilitation is not optimistic. Many patients with mild to moderate hearing loss believe that their current daily communication will not be greatly affected. It will not be too late to wear hearing aids to compensate for their hearing loss in the future. This idea is It's very wrong. As time goes by, the degree of hearing loss may not change, but the speech recognition ability must gradually decline. When it declines to the point that it affects normal communication, it is not an easy problem to recover. Even if Even if you wear a suitable hearing aid but still can't understand it right away, it will be a complicated and long process to regain the lost hearing memory bit by bit.
