Hearing impairment refers to the qualitative or functional abnormalities of the nerve center generators in the auditory system, such as sound, sensory, and comprehensive analysis of sound, resulting in different degrees of hearing loss. Simply speaking, we are commonly known as deafness and back. Hearing impairment can occur in everyone, and there are many causes of hearing impairment, noise, heredity, trauma, organ degradation, drugs, and so on.
Many people think that deafness is a disease that only the elderly can get. Young people don’t have to worry about it. In fact, this is not the case. Although hearing impairment is related to age, it is not the only one.
The deafness that we call the elderly is basically senile deafness. This is because our hearing organs are degraded, and the hearing loss caused by aging is almost impossible for us to avoid. Sooner or later. One day will come to us.
Again caused by noiseNoise deafnessIn fact, this is more common for those of us who live in big cities, the city is full of water, and various entertainment venues.Ktv, bars, etc., the noise in these places is very high, most of themKtvNoise can be achieved90More than decibels, so for people who have been in these places for a long time, noise deafness is inevitable, and some people have done research. In some remote villages and cities, the hearing of rural people is generally higher than that of urban people. Because of the low noise in their environment.
There are also newborn babies who are also suffering from hearing impairments. Most of them are caused by genetic or environmental factors. I will not talk about heredity. It is clear that deafness genes are important factors leading to genetic deafness. Environment The main reason is that the child is still in the fetus, that is, the mother is still pregnant due to external noise, or the mother is suffering from a certain disease, and some of the virus is transmitted to the fetus.
In fact, it is a trauma, and the trauma is actually better understood. The most common one is the slap in the face. It is not uncommon to see a slap in the palm of your hand. Then drugs can cause hearing impairment, but not all drugs can cause convulsions. I am referring to ototoxic drugs. Ototoxic drugs are very likely to cause ototoxic deafness. Therefore, you must ask before using the drug. Doctors to avoid accidents.
When we find that we have hearing impairment, we should go to the hospital as soon as possible, early intervention and early treatment. If there is no effect or poor effect after clinical treatment, we can choose to wear hearing aids to compensate for hearing. Generally, as long as The degree of hearing loss is not very serious, and the hearing loss is not too bad after wearing the hearing aid for a long time.
