Do you know your hearing?

do you know? No matter how young or old, almost no one’s hearing is perfect. Knowing your true hearing situation is the first step in guarding and finding a good voice.

One by one, I think about the medical report you have taken: in the listening column, are there only “pass” or “normal”, with less than two words to bring your hearing? Have you ever thought that with such a simplified result, you can’t understand the whole picture of your hearing. The lack of test data is equivalent to the inability to further judge whether the hearing is “good” or “bad”, and it is impossible to know whether your hearing is “maintained as it is” or “deteriorated” compared with the previous tests.

The hearing loss does not wait until the old age suddenly occurs, the key is in the “hair in the ear.” Don’t think: I am still young, don’t need to know so much! In fact, from birth, everyone must face the test of hearing loss.

Why do you say from birth? Simply put, we can hear the sound, the “hair cells” in the inner ear cochlea are a big hero. The size of the cochlea is similar to that of a pea. There are tens of thousands of “hair cells” inside. It is responsible for converting the sound waves transmitted from the outer ear and the middle ear into neural signals, which are then transmitted to the brain. Then we learned that there is a voice coming!

One by one, these hair cells have all grown up when we were born. However, as the age increases, the ear habits are poor, or the disease factors, the cilia on the hair cells and hair cells are easily damaged and may even die, and our hearing is thus damaged to varying degrees. In general, we believe that the “hearing degeneration” that occurs naturally when people are older, also known as “senile hearing loss”, is one of the common consequences of hair cell damage.

It is worth noting that the senile hearing loss is not “suddenly happening in old age”! Hair cells are damaged, usually starting at a young age, but because they are affected from very high sound frequencies, they are not easy to detect at first. In general, children can hear up to the highest frequency.20,000Hertz, but when we reach adulthood, most of us can only hear12,000~14,000Hertz, maybe even only10,000hertz. However, the frequency of people’s speech is mostly8,000Hertz is below, so we don’t find hearing loss in the early days, but in fact, the deterioration of hearing is happening quietly every day.

More importantly, hair cells cannot be regenerated! In other words, hearing loss caused by damage and death of hair cells is an irreversible process, and lost hearing can no longer be recovered.

The consequences of long-term neglect of hearing by the world have been quite serious. According to the World Health Organization (WHO)data of,65Above age, average per3People have1People have hearing loss problems. More global3.6100 million people, because of hearing impairment, affecting every day, more than the total population5％。WHOIt is further pointed out that half of all current hearing loss cases have the opportunity to be avoided through early prevention.

Understanding your hearing situation is the first step in prevention. Moreover, in addition to aging, there are many possible reasons for hearing loss, such as noise, genes, metabolic problems, vascular problems, ototoxic drugs, bacterial viral infections, vitamins or trace element deficiency, etc., only to track hearing changes early, usually try to Stay away from noise, and when you find an abnormality, actively understand the possible factors and seek treatment possibilities, it is a comprehensive approach to guarding your hearing.

Almost everyone has hearing defects; through technology, find the beautiful sound of forgetting. On the other hand, even if you find that you have hearing loss, it does not mean “the end of the world”! In fact, according to the results of domestic and foreign research and hearing clouds, almost everyone has more or less hearing defects.

One by one, through the help of technology, these hearing defects have the opportunity to improve. In the case of senile hearing loss, if the frequency of speech often occurs, the hearing loss exceeds35decibel(dB HL), hearing aids help to improve hearing. In the past, many elders often thought that wearing hearing aids was a symbol of old age and refused to wear them, but now the technology is quite advanced, and hearing aids can be hidden in the ear canal, and others will not look carefully and will not find it. As for the minor hearing loss, new technologies for improving listening and listening to music and watching movies are emerging.

One ear, let us hear many beautiful voices in the world, it is worthy of our treatment. Starting today, with family and friends, care about listening and enjoy the sound!
