People are not unfamiliar with hearing aids, but in the face of overwhelming advertising and mixed products, many people who need to wear them often don’t know how to choose, or even because of a wrong decision, cause irreparable hearing damage. Not only that, it costs a lot to buy hearing aids. The gap between consumers’ expectation on the effect of hearing aids and many problems after matching lead to disputes. Experts point out that hearing aids also need to be scientifically matched.
Pay attention to the small details of hearing problems
Hearing aids are designed for deaf people and deaf patients. Therefore, before choosing hearing aids, we should first judge the status of deafness.
Because people have bilateral ears to feel hearing, some people who are relatively slow in response in life often fail to find problems in hearing during physical examination. Only when problems occur in one ear, causing inconvenience in life and work, can they find that one ear has been deaf for many years.
There are also some children, due to the lack of expression, who are often ignored after deafness and delay diagnosis and treatment. Some children, when they reach a certain age, are concerned by their parents because they can’t speak or they can’t speak clearly. However, they often miss the best time to intervene and cause irreparable consequences.
In fact, as long as you pay attention to some small details, you may find that your relatives or friends around you have hearing impairment, especially for children who can’t speak. For the elderly, the signs of hearing problems such as loud voice, repeated questions like “what do you say”, “speak up”, “say it again”, etc.; some elderly people have ear blocking, ear tightness and tinnitus, although there is no problem in language communication; some elderly people are slow, slow, self abased, autistic and dare not cross the road, which may be due to hearing problems. For children who have not reached the age of speech, they will have a normal response to the sound stimulation. When there are voice toys around or parents clap their hands, they will turn their heads and look for the sound source with their eyes. When they hear the sound of closing the door, they will also have a very short systemic nervous response. If you watch TV, your child always turns up his voice or answers the phone with one ear, you may have hearing problems.
When hearing problems are found, they should be checked in the hospital as soon as possible to avoid delay.
Not all deafness can improve hearing through hearing aids
Some people mistakenly think that hearing loss or deafness, as long as equipped with a hearing aid on the line. As we all know, not all deaf patients can improve their hearing function through the selection of hearing aids. Moreover, the role of hearing aids is only to amplify the original inaudible sound, and there is no function to treat deafness. Some deaf patients who wear hearing aids due to auditory neuropathy, membranous labyrinthine hydrops and other diseases may not only have poor effect, but also have wrong cognition, mistakenly thinking that it is because of wearing hearing aids that the deafness is aggravated.
In fact, in clinical practice, hearing loss caused by earwax blockage is not uncommon when it is treated with drugs or equipped with hearing aids. People with cerumen blockage in the external auditory canal (commonly known as earwax blockage) may suffer from hearing loss due to the enlargement of earwax after swimming and water entering their ears. However, this situation does not need to be tense. After the doctor takes out the earwax, the hearing will recover soon. In the early stage of some diseases, such as cholesteatoma tympanitis, acoustic neuroma and other causes of hearing loss, can be temporarily compensated by hearing aids, but patients with progressive hearing loss must be examined by a specialist to avoid misdiagnosis and mistreatment. Otitis media, sudden deafness, Meniere’s disease and other deafness related diseases, once found should be timely to the hospital for targeted treatment. For patients with stable or later stage, it is recommended to select hearing aids for auditory compensation.
In addition, human auditory function includes hearing sound and listening clearly. Doctors will give advice to patients according to the degree of hearing loss after hearing test. Generally, mild hearing loss (0-30db) does not need to be selected, moderate hearing loss (40-50db) can be selected, (50-70db) is in the range of optional hearing aids, and severe hearing loss (greater than 70dB) is ineffective or ineffective. Although hearing aids are not available for deaf children, some scholars suggest that they should use high-power hearing aids before the age of 1-2 and cooperate with rehabilitation training, which is helpful for the development of language communication ability. One ear is totally deaf and the other ear is normal. Generally, hearing aids are not needed. For the deaf children with residual hearing, they should wear hearing aids as early as possible and carry out language training as early as possible.
Hearing impairment may be caused if hearing aids are used without fitting
Can hearing aids be purchased at will? No, of course. Like myopia and hyperopia, hearing aids need to be matched. If patients wear it at will, not only the effect is not good, but also may cause hearing damage.
It is a scientific and precise process to test and match the hearing aids. We should not only test and evaluate the hearing comprehensively, but also put the selected hearing aids in the tester for matching. Moreover, it takes a process for hearing aids to work, and it is impossible to improve their hearing at once. Patients should avoid noisy environment in the initial wearing, and pay attention to rest when feeling tired. Because it will take a while to try on the hearing aid, if the subjective feeling is uncomfortable, the hearing aid should be adjusted repeatedly. It is suggested that patients must choose the hearing center or the hearing aid shop in the regular hospital for matching, because after-sales service directly affects the use effect.
Hearing aids are not the more expensive the better. They should be selected in combination with their own hearing loss and economic tolerance and other comprehensive factors. Most of the elderly patients with hearing loss have retired, and the requirements for hearing are mainly to be able to watch TV and communicate with others conveniently. However, the eyes of the elderly are not good, and the fingers are not flexible. Therefore, the main factors to be considered are the moderate price, the convenience of removal, operation and adjustment, and the convenience of changing batteries. Young and middle-aged people, because of the pressure of work and family, and worry about social prejudice and influence on their future, usually have hidden requirements in addition to the functional requirements of hearing aids. So, even if the price is more expensive, the hearing aid with high performance and good concealment is a good choice for them. The shape of the ear canal will change when the children are in the stage of growth and development, so they need to change the shell of the hearing aid regularly, so they can choose the ear back hearing aid to reduce the cost of changing the ear mould. When the development of the ear is basically mature, it can be considered to change to a more concealed type.
In addition, since most hearing aids are currently electronic products placed in the external auditory canal, keeping the personal auditory canal clean will extend the service life of hearing aids. Otitis media, eczema of the external auditory canal and cerumen of the external auditory canal may all affect the effect. It is necessary to avoid the hearing aid from being damped, bumped, littered and placed around. It is also necessary to regularly go to the fitting center for deep cleaning and nursing. The battery compartment should also be put into a dry box for dehumidification.
