this article discusses the importance of selecting hearing aids and emphasizes the professional fitting technology in regular hospitals.personnelnecessity to complete the selection. the author points out that the randomly purchased hearing aids may not only fail to play the role they should, but also aggravate hearing damage. before choosing a hearing aid, older people need to undergo multiple tests, including examining the external auditory canal and doing audiological tests. depending on the patient's age, occupation and life needs, the doctor will help select the right type of hearing aid. debugging hearing aids andevaluateeffects are also very important steps. finally, developing a follow-up plan is key to ensuring that hearing aids continue to function.
1. before wearing it, you must first observe the left and right ear signs on the hearing aid. the red sign is the right ear and the blue sign is the left ear. 2. when the battery is placed, the plane of the battery ( +positive electrode) corresponds to the positive electrode mark in the battery compartment ( +),be careful not to let go of the opposite. 3. after removing the hearing aid, open the battery compartment door to prevent the hearing aid from power off and stop working, preventing unnecessary power consumption. 4. after putting on the hearing aid, press the ear canal with your hands again. you can ask your family to help check whether it is worn properly. 5. wipe the sweat left on the hearing aid after sweating with a dry wipe or glasses cloth. 6. the hearing aid battery is a zinc empty battery and must be kept sealed during storage. the film cannot be removed. when replacing the new battery, remove the film and let it sit 2 ~3after letting the battery fully contact with the air, put it in the battery compartment. after removing the film, even if it is re-sticked, it will naturally consume power. 7. when not wearing a hearing aid during the day, you can open the battery compartment and put the hearing aid in a small box that is standard, and put it in a drying box when not wearing it at night to fully remove moisture. 8. observe whether the color of the desiccant becomes darker or lighter (different brands of desiccants are different, and the guidance is provided by the audiologist when purchasing). if the color changes, change it in time. 9. do not wipe the ear mold with alcohol, as the ear mold material is prone to aging. 10. before wearing an ear-back hearing aid, pay attention to whether there is water and gas blockage in the sound guide tube, especially in winter, when the temperature difference between indoor and outdoor is large, water and gas are easily accumulated in the sound guide tube, resulting in silence of the hearing aid. solution: pull out the connection between the sound tube and the ear hook, swing it hard, or use a blowing balloon to suck out the water, and then install the sound tube. 11. the ear canal machine or external hearing aids on the receiver need to be cleaned regularly, or replace the acne baffle (white accessories in the sound outlet hole). if it is blocked, it may cause silence or low sound. usually, you can brush the sound hole facing down and use a small brush. if it cannot be brushed off, you need to replace it with a new one. 12. when washing your hair, washing your face, and taking a bath, you need to remove the hearing aid. 13. hearing aids havewhenwhat's going on when it makes a "squeak" whistle? it is normal that "squeaking" sounds may occur during the hearing aids not being worn or removed. when worn, hearing aids will not scream. 14. what if you accidentally drop the hearing aid into the water? first, take out the battery in time, and wipe the water with a dry wipe. do not start the hearing aid again and listen to whether there is any sound. put it in the drying box to remove moisture for 24 hours. contact a hearing aid for hearing aid testing or repair during the tide removal process.
when wearing hearing aids, you should pay attention to the adaptation process and also pay attention to the maintenance of hearing aids. 1. pay attention to the process of adaptation. if the patient cannot adapt to hearing aids, he/she should find a professional pilot or audiologist to adjust the machine in time. 1、adaptation to the environment. patients should first wear hearing aids in a quiet environment, and then wear hearing aids in a noisy environment to ensure that the use of hearing aids is not affected by the environment. 2、adaptation to time. patients should wear hearing aids every day 3 ~4when the patient is young, the daily time to wear hearing aids is gradually extended, and the patient can finally wear hearing aids for all the time except sleep. 3、adaptation of communication objects. patients should communicate with one person first, and then gradually communicate with multiple people, so that the voice can be switched smoothly. 4、adaptation to listening distance. patients should first listen to sounds from close range, then hear sounds from far range, and feel the difference in sounds after the distance changes. 2. pay attention to the maintenance of hearing aids. 1、anti-fall. when the patient takes the hearing aid out of the ear, the hearing aid should be prevented from falling to the ground. 2、moisture-proof. if the patient is in a humid environment, you should put desiccant in the box where the hearing aid is placed to prevent the hearing aid from leaking after becoming wet. 3、water proof. although new hearing aids generally have waterproof functions, patients should prevent hearing aids from being exposed to water as much as possible. 4、remove the battery in time. if the patient does not use the hearing aid for a long time, the battery inside the hearing aid should be removed to prevent the battery from leaking and corroding the hearing aid.
hearing aids, as the name suggests, are tools to help the human ear listen. it is a device that increases the intensity of sound that can help some hearing impaired patients make full use of residual hearing and thus compensate for hearing loss in the deaf ear. as a hearing recovery method, it cannot restore hearing to normal in patients with hearing impairments, but it can amplify the sound to a level that the patient can hear, helping patients with hearing impairments communicate better with people. currently, there are nearly 100 million people with hearing disabilities in the world, and my country's hearing isspeechthere are about 27 million people with disabilities, an estimated growth rate of 20,000 to 40,000 per year. if elderly deafness and noise deafness are added, it is estimated that 30-40 million people need to improve hearing. with the improvement of people's living standards and the increasing frequency of social interactions, the demand for hearing aids by patients with heavy listening is increasing year by year. the technology of hearing aids has gone through four eras: non-electricity, electrical amplification, vacuum tube and transistor. with the development of technology and the application of digital technology, hearing aids can widen the hearing dynamic range of patients and improve auditory comfort. it can not only improve the amplification ability of signals and the resolution of signals when input at low intensity, but also improve the speech recognition ability of patients in noise environments, so that hearing impaired people can hear clear speech in noise environments. step 1: avoid hearing difficulties in starting a "hearing training" course in a familiar environment, carefully read the operation instructions, and be familiar with how to use the hearing aid; in the first few weeks, do not wear hearing aids in noisy places, such as supermarkets or airports. step 2: slowly increase the time you wear hearing aids at the beginning, never use them for too long. during the first few days, the hearing aid should not last more than one to three hours. when you feel nervous or tired, you should remove the hearing aid and rest for several hours. there is one thing that is very important during the trial period, that is, you should increase the time you wear hearing aids every day so that you can slowly adapt to the sound of your surroundings. step 3: control the volume and do not turn the volume too high. in many cases, this will not only not improve the ability to understand the conversation, but will instead cause sound distortion. don't try to make a slight sound in the distance. at this stage, it is enough if you can have a general conversation within 2 to 3 meters. step 4: adapt to the use of hearing aids. ideally, your hearing aids should become a part of your body, just like hyperopia and myopia glasses and contact lenses. however, this process is gradually coming and requires some effort to treat hearing aids as friends rather than some "device outside the body". step 5: learn to listen in a noisy place. users of hearing aids need to concentrate on listening to the sound they want to suppress the disturbing noise in a noisy environment, just like other people with normal hearing. however, if your hearing loss lasts for quite a long time, you will temporarily lose this ability. the hearing aid users' ear health has declining hearing is a manifestation of body aging and organ aging. under the stimulation of external hearing aids, most people can use the residual hearing to perceive part of the external sound. however, long-term use of hearing aids will inevitably cause fatigue of the inner ear nerves. long-term fatigue causes the inner ear nerves to age again, and the hearing will gradually lose. nowadays, many hearing aid business units promote the use of hearing aids to promote the activation of the inner ear nerves and enhance hearing. the benefits of hearing aids are more inpsychologyaspect,becauseafter wearing hearing aids, the organ perception ability will improve, and it will not be possible to interact with people.question,increased self-confidence can reduce deafnesspsychological effectsnegative effects of hearing. the auditory nerves and hearing organs must be maintained, which is a place that people wearing hearing aids are prone to ignore. for those who use hearing aids, it is particularly important to take off the hearing aids and nourish their auditory nerves during rest, so that the ear nerves have sufficient maintenance time. when wearing hearing aids in the elderly, please pay attention to wearing hearing aids. it is an important means to improve the hearing of deaf elderly people. however, hearing aids cannot be purchased and used at will and must be strictly fitted before they can be worn. when the elderly are fitted with hearing aids, they should usually pay attention to the following points: 1. for newly occurring elderly deafness, do not rush to wear hearing aids. they must undergo a period of clinical treatment. if there is still no improvement, consider wearing hearing aids. premature wearing of hearing aids may aggravate deafness due to strong sound stimulation. 2 before fitting a hearing aid, a professional doctor must conduct a comprehensive examination and choose a suitable hearing aid based on the degree of hearing loss. never buy it yourself or wear it at will to avoid damaging your remaining hearing. 3 in elderly people with deafness, the degree of deafness in both ears is often inconsistent. generally speaking, hearing aids should be worn on the side with poor hearing so that the other ear can still listen to the sound of nature, so that the hearing of both ears is as harmonious as possible. if one ear is moderately deaf and the other ear is severely deaf, it should be worn on the side with better hearing, so that the best listening effect can be achieved. for moderate to severe deafness with consistent levels of both ears, binaural deafness should be worn to relieve fatigue. 4 the elderly have an adaptation period when wearing hearing aids, about three to five months. during the adaptation period, the volume of the hearing aid should be turned on as low as possible. at the beginning, the wearing time should not be too long. it can be 1-2 hours a day and gradually increase it later.
