Deafness means that you can’t hear any sounds?
It is generally believed that the average hearing threshold for language frequencies (0.5, 1.2Hz) is above 26dB, that is, there is hearing impairment. Those with hearing loss within 70dB are called hard of hearing, and those with hearing loss above 70dB are deaf. Clinically, they are collectively referred to as deafness. In terms of the location of ear disease damage, deafness can be divided into acoustic deafness and sensorineural deafness. Due to lesions in the outer ear and middle ear that hinder the conduction of sound waves, this is called acoustic deafness. If there is a problem with the inner ear that receives sound waves or the path from the inner ear through the auditory nerve, affecting the perception of sound, it is sensorineural deafness. Deafness caused by lesions in all three parts of the outer ear, middle ear, and inner ear is called mixed deafness.
Many people think that deafness means being unable to hear any sounds. In fact, this is incorrect. Hearing dysfunction and varying degrees of hearing loss are collectively referred to as deafness. Being unable to hear does not mean total deafness. It is generally believed that when the hearing loss is above 25 decibels, it is called hearing loss or hearing impairment. When the hearing loss reaches 120 decibels, we can call it total deafness.
According to the degree of deafness, deafness is divided into mild deafness, moderate deafness and severe deafness. Its grade is mainly divided according to the frequency of speech.
Mild deafness: The average hearing is between 26 and 40 decibels. When listening at a distance, the hearing is not very clear. There is no difficulty in general conversation.
Moderate deafness: The average hearing is 41 to 55 decibels, which is called moderate deafness. It is worse to hear sounds, and it is difficult to listen to words at close range; the average hearing is 56-70 decibels, which is moderate to severe deafness. It is difficult to hear loud words at close range. There will be difficulties.
Severe deafness: The average hearing range is 71-91 decibels, which is considered severe deafness. You have to shout loudly in the ear to be heard. When the average hearing is above 90 decibels, it is called profound deafness, and you cannot hear loud words in your ears.
So the degree of deafness is different, the reaction to hearing sounds is also different, and the symptoms and feelings are also different.
Judge the severity of deafness from the details of life
The degree of deafness of the deaf person or the patient himself can be judged from his reaction to external sounds.
Deafness can be mild, moderate or severe. If you speak to him loudly, he can hear it, but if you speak softly, he cannot hear it. Then this may be a moderate deafness. If you speak loudly, he will not hear it. His hearing is not very good. When watching TV, he has to turn the sound very loud. Others think it is deafening, so that he can hear comfortably. His degree of deafness is relatively severe. In addition, deaf patients themselves can alsoYou can judge whether your hearing is good or bad based on how outsiders speak and how you respond to outside sounds.
For children with deafness, we need to look at the time when the child learns to speak. When the child does not learn to speak or has not yet learned to speak, the child’s reaction to external sounds, such as thunder, , close the door or give him a small sound and knock something. If he can hear it, respond and turn around to look for it, it means he can hear it. Then, observe the baby's reaction by giving him a louder sound. to determine the severity of the child's hearing loss.
How to judge whether you are deaf
When the person next to you says that you have to raise your voice to speak to you, you can hear it, or when you are not paying attention When you hear someone say that your hearing is not very good, you should pay attention. Another thing is that when watching TV, the volume of the TV should be louder than that of normal people, which means that your hearing is not good. When answering the phone, if one ear is deaf, the bad ear cannot hear the phone clearly and the sound is farther away, while the sound heard with the healthy ear is very clear; if you whisper, the bad ear will not hear clearly. I can't hear clearly, I have to raise my voice a little louder to hear clearly.
When we find out that we are deaf, we should not think about delaying it as long as we can. We still need to go to the hospital for intervention in time. Once it is found out through the hearing test, your hearing will be affected. If the loss is greater than 35 decibels, you need to intervene in time and wear a hearing aid. Although wearing Hearing Aids cannot help us restore hearing, it can improve the current hearing situation. It can also protect our residual hearing, slow down the rate of hearing loss, and prevent problems with our speech recognition ability.
