'r r', Will wearing hearing aids worsen deafness? Many people feel that as time goes by, the prescription of glasses becomes higher and higher, and the vision becomes worse and worse. Therefore, they infer that hearing will get worse after wearing hearing aids. Is the truth really like this? ? ? We all know that if a person with myopia does not wear glasses, the power of the glasses will gradually increase and the vision will gradually decrease. The same goes for deaf people. If they do not wear hearing aids, their hearing will get worse and worse, and hearing aids can effectively alleviate hearing loss. Why do some people say that the more they wear hearing aids, the more deaf they become? There is a situation that is often encountered: many patients find it troublesome and are unwilling to accept formal fittings, so they choose to buy cheap hearing aids online or in pharmacies. Although hearing aids can improve hearing conditions, if they are not fitted according to the actual situation, they will only be counterproductive. Hearing aids without adjustment are like glasses without lenses. What you buy is just a frame, but it is not practical.

What are the types of hearing aids
There are many types of hearing aids according to classification: Hearing aids can be classified in many ways, and they can be divided into box-type according to their appearance. , behind-the-ear type, customized type (in-ear type, ear-canal type, deep-ear canal type), etc.
. According to their appearance classification, they can be divided into five categories according to their appearance: box type, glasses type, behind-the-ear type, in-the-ear type, and bone conduction hearing aids. Among them, spectacle-type, behind-the-ear, and in-the-ear hearing aids are also called ear-level hearing aids. The way ear-level hearing aids receive sound is closer to the physiological state than other types of hearing aids.
. According to their technical principles, they are classified into electric hearing aids, electronic tube hearing aids, semiconductor hearing aids, integrated circuits and programmed hearing aids. If hearing aids are classified by the extent to which they adopt digital electronic technology, then hearing aids before integrated circuit hearing aids all used analog electronic components. Starting from programmed hearing aids, digital electronic chips enter the hearing aid to control the work of other analog components, which is called Digital-analog hybrid circuit.
.According to the scope of functions, they can be divided into group hearing aids and individual hearing aids. As the name suggests, individual hearing aids are suitable for a certain individual. Group hearing aids are mainly used for audio-visual teaching and outdoor teaching, and are especially suitable for rehabilitation institutions or school education for deaf children. According to their specific functions, they can be divided into the following three categories:
Fixed wired collective hearing aids This type of collective hearing aid is actually similar to the speech classroom system used in foreign language spoken teaching.
The sound source of the FM hearing aid passes through an FM signal generator (similar to a wireless microphone) and is received by one or more FM hearing aids.
Closed-circuit electromagnetic induction collective hearing aid system This hearing aid system consists of amplification, frequency modulation components, coils and individual hearing aids pre-placed in indoor places such as classrooms and homes.
Each hearing aid has its own advantages and disadvantages, so there is no clear definition of the best, only the most suitable. For example, older people prefer simple box-type hearing aids, while young people are suitable for hidden-ear hearing aids. Internal hearing aid.

What are the characteristics of presbycusis
Presbycusic hearing loss is caused by the deterioration of auditory physiological functions caused by aging. It is mostly manifested as high-frequency hearing loss and has a negative impact on language. The ability to distinguish is reduced and it is difficult to hear clearly what others are saying. And as age increases, hearing loss will gradually increase.
Feature 1:
Many elderly people with deafness can still hear if their family members speak loudly.
Feature 2:
When talking to an elderly person who is deaf, although he can hear what you say, he doesn’t hear much clearly.
Characteristic 3:
If you talk to him in a noisy environment, it will be difficult for the elderly to hear what is being said.
Feature 4:
If you are not talking to the elderly person within his field of vision (such as standing behind the elderly person), the elderly person cannot hear what you are saying.

'r r', Where does hearing aid noise come from
Some users will feel obvious noise when wearing the hearing aid, and they will wonder whether there is a problem with the hearing aid itself. For this problem, we must first Figure out where the noise is coming from. From the technical analysis of hearing aids, hearing aid noise includes:
. The internal background noise emitted by the hearing aid itself
. The amplification of external environmental noise by the hearing aid when it is working
The impact of the technical content of the hearing aid on the noise Impact:
.The noise emitted by the analog hearing aid itself is around & decibels.
.The noise emitted by the fully digital hearing aid itself is around & decibels.
Due to the working principle of the analog hearing aid, it does not take any intelligent measures in the process of amplifying the external environmental noise. It amplifies the external sound through the same amplification principle, so the wearer often walks in a crowded place with many people and cars. On many highways, hearing aids may sound very noisy. There are too many noises, which makes you feel uncomfortable, and the effect of verbal communication with others is not very good!
Because the working principle of fully digital hearing aids is essentially different from that of analog machines, especially when complex external environments invade, the machine’s internal ability to process external sounds becomes apparent. It uses effective compression (simulating the human ear cochlear function) to alleviate the interference caused by noise to the human brain's thinking. Effective and targeted compression processing of each frequency band of the sound makes us feel more natural when listening and not uncomfortable. The sound characteristics of all-digital hearing aids can be summed up as follows: it is not uncomfortable to play loudly, and you can hear it softly!
Conclusion 1: The background noise of fully digital hearing aids is better than that of analog hearing aids.
Conclusion 2: All-digital hearing aids are better than analog hearing aids in processing external environmental sounds. This can further reduce the interference of external noise on the brain.
Types of noise: There are many types of noise, such as the sound of cars on the road, the noise in the crowd, the harsh sounds from other objects, unbearable loud sounds, and the artificial noise made by people in daily life when they are working. The sound of machinery in the workplace, etc.
Why can we normal people adapt to the existence of this kind of noise relatively easily? The main reason is that we have a healthy cochlea. The function of the cochlea is to deal with the interference of external noise on the brain, eliminate all intrusions of sounds that cause brain fatigue, and play a filtering role. But for a deaf friend, especially neurological deafness, due to damage and disease of the cochlea, its own compression function has been greatly weakened, and the compression function of the hearing aid is needed to compensate! Therefore, the effect of wearing a fully digital hearing aid with compression function is better than that of an analog hearing aid.
The impact of different degrees of deafness on noise sensitivity: This is a very scientific question. Through constant experience summarization, we have come to the conclusion that the more deaf a person is, the worse their sensitivity and perception to noise are! In other words, the more deaf a person is, the less he can feel the presence of noise, and the less fatigue it will cause to his brain. For deaf elderly people with hearing loss > decibels, when they wear simulated hearing aids, % of them will not feel the negative impact of external noise on the brain, and there will be no discomfort in wearing hearing aids. When the hearing loss is less than decibels, more than % of the elderly will experience varying degrees of effects on the brain caused by environmental noise, thus affecting their enthusiasm for listening to sounds and their persistence in wearing hearing aids! In addition, from a professional perspective, those deaf elderly people with lower discomfort threshold are more able to perceive the intrusion of noise!
(Discomfort threshold: a person’s ability to withstand the loudest sound.)
Many patients have been in a relatively quiet environment for a long time. When they first put on a hearing aid, while the speech sound is amplified, the noise is also amplified to a certain extent. It is often difficult for patients to adapt and requires a certain adaptation period before they feel too noisy.
When fitting and debugging hearing aids for patients, the hearing aid technician must fully understand the patient's sensitivity to noise and the performance of the hearing aid, and set the best hearing aid status for the patient in a timely manner so that the patient can withstand the noise in the environment. Noise helps patients go through the adaptation period smoothly and not be bothered by noise.
So our final result is that noise intrusion is directly related to factors such as the choice of hearing aid, the degree of deafness of the deaf patient, the hearing threshold of the deaf patient, the patient's adaptation, and the ethics of the hearing aid provider.

Active feedback interception of hearing aids
Clinical tests have shown that Diting's active feedback interception technology is shocking and unparalleled.
, one feedback filter per HZ, frequency band feedback elimination, quickly and completely eliminate feedback
, instantly intelligently identify changes in feedback paths
, prevent the occurrence of entrained sound, and completely eliminate entrained sound
br />. The most important thing is that it provides an additional retained gain of up to dB, truly eliminating feedback and achieving high power without feedback.
Dr. r, Dr. h Br and Dr.
r compared the feedback cancellation performance of top hearing aids from each company, including additional retained gain, processing of entrained sound, sensitivity to feedback path changes, Finally, it was found that Diting was far ahead in all three aspects. There is no doubt that Diting's active feedback interception is the best in the industry.
Dr. r, Dr. h Br and
Diting’s active feedback capabilities are second to none in the industry. With DiTing, feedback no longer exists. You can easily make phone calls, whisper to your loved ones, join in a sing-along, and hug happily.
Did you know?
When patients wearing hearing aids make phone calls, wear hats, hug, eat, chew, or even smile, they are prone to produce acoustic feedback. Feedback is the main reason why hearing patients are unwilling to wear hearing aids, and it is also the main reason for repeated adjustments. Hearing aid repairs due to feedback account for approximately % of overall repairs.
