What are the characteristics of Chinese speech? It’s very loud. It may be that people all over the world, including the Chinese, have such an impression. There’s a story about two Cantonese speaking in Chinatown. The Americans thought they had a fight and called the police. When the police came to ask, the young man in Guangdong said, “we are whispering!” in fact, despite the cultural reasons, have you ever thought about it? Hearing loss is also a factor.
Noise pollution to make trouble
According to statistics, there are 27.8 million hearing disabled people in China, an increase of 300000 every year, which is the largest hearing disabled country in the world. There are more than 200 million people aged 60 and over in China, accounting for 14.9% of the total population. The annual growth rate of the elderly population is even faster than the world average. Research shows that more than 35% of the elderly in China have different levels of hearing impairment.
There are more and more cases of hearing loss in Chinese people, and patients with sudden deafness tend to be younger and younger. She recently received a sudden deafness patient, who was only nine years old. “The cause of deafness in patients is usually not clear, but it has a lot to do with the fact that they have been in a noisy environment for a long time, or listening to high pitched headphones for a long time.” More and more people are used to shouting. There are also environmental reasons. With the development of industry, the environment Chinese people are facing is generally more and more noisy, which may also be one of the reasons why we keep raising our voice. In the same way, this is an important reason why our hearing is becoming more and more fragile.
Bad habits are accomplices
It’s true that hearing declines with age, but bad living habits play an “accomplice” role. Many people often wear earphones to listen to music. In noisy environments such as buses, subways, and noisy streets, the sound is even louder. Others like to wear earphones to listen to music before going to bed and fall asleep unconsciously. They like to turn on the TV sound very loud, just like placing a strong sound source in their ears. This bad habit of using the ear will lead to hearing loss.
In addition, the damage of some drugs to the ear is more easily ignored, such as streptomycin, gentamicin, kanamycin, neomycin, etc. They can damage the inner ear (including the cochlea and vestibule), cause deafness and imbalance. At the same time, mental tension, too much pressure and lack of sleep can also lead to blood supply disorders in the inner ear, leading to hearing loss.
To maximize the protection of hearing after old age, we should develop good ear habits at ordinary times, do not wear earphones for a long time, and do not open the voice too loud; when taking ototoxic drugs, please follow the doctor’s instructions, and never buy or eat by yourself, especially those who have ear disease or renal dysfunction should pay more attention. In addition, do not often use ear scoops, matchsticks and other hard things to dig ears, so as to avoid damaging the ear canal and causing infection. Once suffering from otitis media and other ear diseases, should be timely treatment.
In addition, hyperlipidemia, coronary heart disease, hypertension, diabetes and other chronic diseases will also affect the blood circulation of the inner ear and affect hearing. Therefore, active prevention and control of systemic chronic diseases is also helpful to prevent the occurrence of senile deafness. It is suggested that people over 60 years old should go to the hospital regularly to test their hearing (once every half a year).
