Hearing aids and elderly care _ xingfuhua open

Health is an important part of his happiness. At present, China's ageing population is gradually increasing, according to the 1998 statistics show that China's 60 years old account for first in the world. Elderly health care is very important, we often speak of the elderly to live happy lives, where health is happy most of the content. Without healthy old age, there will be no happiness. 1, listening and innate. And full of life are inseparable. Physiology tell us when the stock tires, mature form of a bone are our ear ossicles inside. Also in the mother's body can feel the sound, so in recent years to an unborn baby's prenatal education to listen to music. People born after entering the wonderful world of sound. Baby can hear the sound of nature reflects the requirements of intimacy, eat, drink, sleep needs and so on, but can't hear sounds are inexplicable fear. Description of sound important for us. Human evolutionary in nature during the exchange of tools--language. The language is thought. No language has no idea. This description of nature give human auditory function that it is very important. There are sound and hygiene, and at home in our family, and friends, and bridges in the world. Lose it, we will work with the relatives and friends from far, and isolation, life will become not so good. Lose it our physical and psychological harm, all affect our health. 2. listening recession is a natural phenomenon. Due to the nature of the law, every man is to old, after entering the old physical has many changes. For example, dazzle, hearing loss, hair loss, limb weakness, and so on. But the history of mankind, the ancient medicine and modern medicine have told us through campaigns can be effective in addressing aging phenomenon. Chairman Mao had used this kind of physical phenomena to describe our work, said: "the water does not rot, households are not beetle, the Council stated that they have kept the microorganisms in the movement of resistance or other bio-erosion." Very vivid description of life and exercise. In the human aging process, the auditory organs are ageing. Sound frequency is 0 �� 20000 cycles per second. In 2-3 years old when the ear can hear 0-18000 Hertz's voice, but 30 years later, the hearing began to decline. A trained person, such as a piano tuner, you can still distinguish 16000 Hertz's sound, but most people have not heard. 40 years after hearing begins to decline. Over 70 years, generally have to moderate hearing loss with hearing aids should be worn. 3, hearing loss classification standards. Our measurement standard ear listening and the same international standards. 0 to 8000 Hz voice as ear listening frequency range. 500, 1000, 2000 Hz three frequencies, the average of the value of listening PTI is called average hearing loss. 125, 250, 500, 1000, 2000, 3000, 4000, 6000, 8000 Hz each frequency hearing in the 0-25 DB hearing, 26-40 DB for mild hearing loss; 41-70 to moderate hearing loss; 71-85 decibels to severe hearing loss; 86 decibels above is extremely severe hearing loss; 120 DB above is deaf. 4. What is presbycusis and harm. Old comrades of deafness, if not the younger due to illness or other causes of deafness, but you get old nature of deafness, hearing loss, said older sensorineural hearing loss. (What is sensorineural deafness; what is sensorineural hearing loss; what is a central hearing loss) mainly due to the aging of hair cells. The audiogram is a low-frequency hearing loss, sometimes 250, 500 Hz for normal; high-frequency loss, 3000 Hz or more often as 90 decibels. Showed a unilateral downlink graphics. Average hearing loss in patients with early stage are generally not severe, as the 40-70 DB. This type of hearing loss and deafness in performance is very similar with presbyopia, is unwittingly evolved. Due to hair cells are arranged in a spiral, at the bottom of listening to the hair cells in the years maximum workload, so often compromised, and that part of the listening to the hair cells are used to sense high frequency sounds. Low frequency sound and high-frequency sounds in language sound effect is different in that the low frequency sound accounted for about 70% of the sound energy, mainly on the sound perception of contributions, on the sound of resolution contribution accounted for only 30%; high-frequency sound approximately 30% of the sound energy, but the audio resolution contribution, approximately 70%. This shows the main impact of presbycusis is on sound resolution, hear, hear. Presbycusis effects on human health, on the one hand, to communicate with people in patients with difficult, resulting in low self-esteem, unwilling to communicate with people, isolated from the outside world. On the other hand is less Exchange with the outside world, the brain exercise reduced, increasing the suffering from senile dementia. According to statistics in Beijing, the city's old age dementia patients accounted for 23% of the older population, this number is higher than the average level of developed countries. One important reason is not wearing a hearing aid, so that part of the old comrades dementia disease exacerbation. Typically as the age increases, cerebrovascular of hardening, brain atrophy is inevitable, which can cause dementia. But mild and moderate Alzheimer's disease, general performance is forgetful, reflecting the slow, headache, dizziness, difficulty in action, but still living, healthy and happy life. But if you already have Alzheimer's disease, is still not active brain exercise, causing severe dementia, it can cause life cannot take care of themselves.
