Experts say that hearing aids must be fitted and adjusted by professional fitters to ensure good hearing aid use. Otherwise, the hearing may be further damaged. The woman in Zhengzhou found that her father’s hearing was in serious decline, so she decided to get a hearing aid for the old man. “There are stores selling hearing aids everywhere, with many brands and models.” Ms. Chang was confused: how can I get a suitable hearing aid for my elderly? The brand is many, the store is many Zheng University Hospital on the university road, the provincial people’s hospital on the latitude five road, Henan College of Traditional Chinese Medicine Hospital on the people’s road …… reporter visited, where the large hospital near are covered with hearing aids sales outlets. According to industry insiders, at present, Germany Siemens, Denmark Rishengda, Switzerland Phonak, Denmark only hear, Denmark Oticon, the United States Stark and other international brands have been stationed in Zhengzhou market, in addition to some domestic brands. The hearing aids on the market not only have more brands and styles, but also vary greatly in price, from a low of four to five hundred yuan to a high of tens of thousands of yuan. ”My relative is more than 70 years old, his ears are a bit back, and he wants to get a hearing aid.” In a store selling several brands of hearing aids on University Road, the salesperson took out a brand of “behind-the-ear machine” and told the reporter that the hearing aid could be hung behind the ear and the volume could be adjusted by himself, so he could use it without a hearing test. However, in another nearby store, the staff told reporters that hearing aids for the elderly must be checked first, and it is best for the elderly to try on the hearing aids. The hearing aid must be checked first. “Hearing test is necessary for hearing aid.” The first affiliated hospital of Zhengzhou University, Lu Wei, chief physician of the Department of Otolaryngology, said that senile hearing loss is a decline in hearing due to the gradual aging and degeneration of the human auditory system, accounting for more than 60% of the total population with hearing disability in China. The hearing loss is mostly manifested as a significant decrease in high frequency hearing and speech recognition, which is called “hearing, inaudible, unintelligible”. From the clinic, with the improvement of living standards, more and more elderly people have come to the hospital to request hearing checks and hearing aids, “the actual hearing of the elderly is different, the applicable hearing aids are also different”. For example, if an old man can hear the sound of a car horn on the road, his hearing level is 60 decibels, while a normal person speaks at 20 decibels. Then, he needs a hearing aid that can raise the sound of human speech to 60 decibels (correspondingly, the environmental noise will also be amplified). The higher the decibel level that needs to be raised, the higher the power of the hearing aid and the higher the price will be. It is said that the process of hearing loss is usually silent. Because the hearing range of human is very large, the general damage may not affect the communication with others temporarily, plus there is no detailed hearing examination in the routine medical examination, so it is difficult to cause people to be alert. If you find that an elderly person has frequent tinnitus or hearing loss, it is best to go to the hospital for a simple hearing check before choosing to get a hearing aid. At present, the cost of a hearing test in a hospital is about 70 yuan, and some professional hearing aid dispensing organizations offer free tests. The best hearing aid is the one that suits you There are many styles of hearing aids on the market, including box, in-ear, and in-ear. It is understood that hearing aids are electronic products, like TV sets and high-end stereos, and generally speaking, the more expensive the hearing aid, the more complete the function and the better the resolution of the sound. A good hearing aid is very “intelligent” and can differentiate between high and low tones while ensuring the purity and stability of the tone, and more importantly, it can filter noise and adjust the volume intelligently according to the changes in external sound. ”The standard for a good hearing aid is high power and low noise.” Lu Wei said that the box type machine is less expensive, but the technology is backward and the slight friction of clothes will bring noise, which has stepped into the ranks of elimination; while the deep ear canal type hearing aid is expensive and more suitable for young patients with high requirements for aesthetics; in contrast, the ear hanging type and ordinary in-ear hearing aid are more suitable for the elderly. Patients can choose according to their affordability and hearing condition. It is understood that the quality of all major brands of hearing aids is basically good, “just like buying a computer is not just hardware, but also a variety of software, so that you can really use. So, only after the professional fitting and debugging personnel, testing accurate, well adjusted, to ensure that the hearing aid good use effect.” Lu Wei said that the doctor mainly comes to diagnose the cause of the patient’s hearing loss, the reason is different, the choice of hearing aids are also different. If you don’t get the right fit or the right tuning, it will not only cause headaches and dizziness, but may also further damage your hearing.
