Hearing aid technical channels and frequency bands For hearing rehabilitation workers, most hearing aid dispensers will think of the concepts of channels and frequency bands at the beginning. Understanding is a difficult point, and there will always be some specious and unclear feelings. With the rapid development of modern high-tech, hearing aid digital technology has undergone rapid changes. This makes processing technologies such as compression noise reduction feedback suppression in the hearing aid channel particularly important. In fact, there are three conceptual frequency bands and programmable frequency bands involved. So why are there so many concepts? What are the differences and connections between these concepts?
First of all, we have to talk about the complexity of sound. It is with this complexity that our lives have become so rich and colorful. The sound world, such as some beautiful sounds, is composed of sound source and propagation medium, but the sound itself has frequency. Characteristics and sound intensity characteristics. If sound had only one frequency, it would be as boring as if we could only see one type of light. It is precisely because of the frequency characteristics of sound that such a complex and wonderful world of sound, language, music, noise, etc. is formed.
Our normal human ears can hear sounds of different frequencies between HZHZ. A frequency band is a combination of various adjacent frequencies divided according to the frequency characteristics of sound. For example, HZ is a frequency band, and it can also be HZ. It can also be a frequency band. HZHZ can also be a frequency band. Frequency band is a signal-level concept, which is a sound signal processing platform for each frequency band combination. Channel is a hardware level concept. The core of digital hearing aids is D (digital signal processor). For the multi-channel hearing aid, there are many independent electronic circuit units in D. The structure and function are exactly the same. Each unit independently calculates and processes different frequency band sound signals. Because each unit is processed relatively independently and simultaneously, it is called a channel. Just like a traffic road, it can be divided into two lanes, four lanes, six lanes or eight lanes. The more channels a hearing aid has, the more refined it will be in processing sound. Sink ratio, compression, knee point, start-up, release time, gain, output, noise reduction, etc. can all be processed in independent channels. This can make the hearing aid output sound quality clearer, more natural and more comfortable.

What factors will affect the effectiveness of hearing aids
Hearing aid users Worried about not being able to live a daily life without hearing aids. In hearing clinics, we often encounter hearing-impaired people of different ages. They are very satisfied with the effect of the selected hearing aids and indeed feel that it has greatly helped their work and life. However, during follow-up visits, they often It was found that they did not often use hearing aids. When you further inquire and investigate their reasons, these hearing aid users will tell you very worriedly that they are afraid that they will be unable to leave the hearing aid after they are used to it. Before using the hearing aid, their difficulties in life were just like this. They will feel very uncomfortable without hearing aids. It is this concern that prevents them from continuing to use hearing aids effectively. They often use hearing aids as reading glasses and only take them out when reading books and newspapers. People with this attitude towards using hearing aids often have a limited amount of information that their brain's auditory center can obtain through hearing aids, making a suitable choice. A good hearing aid doesn't work to its full potential.
Evaluating whether a hearing aid is suitable depends on the patient's dependence on it. The higher the degree of dependence, the more helpful the hearing aid is to the patient. If the hearing aid is dispensable for this patient, either the patient's hearing loss is very mild or the hearing aid is not effective for him. In fact, human beings' dependence on science and technology reflects the civilization of human society. It is difficult to imagine how people in the collective society can live without electricity, telephones, computers, and advanced transportation. Therefore, hearing-impaired people should accept the help of hearing aids as openly as they accept telephone calls.
The degree and nature of hearing loss. According to relevant surveys, patients benefit from hearing aids and the time they use hearing aids every day increases with the degree of hearing loss. Generally, the proportion of patients with flat hearing loss using hearing aids is higher than that of patients with simple declining hearing loss. There are more patients with loss. Although loss in any frequency range is very important to patients, in most cases the degree of hearing is more closely related to low-frequency hearing thresholds than high-frequency hearing thresholds.
In clinical practice, there are also cases where the patient's average hearing loss value (the average hearing loss value is calculated based on the degree of hearing loss at a common frequency HHzHz) is not necessarily proportional to the effect of the help the patient receives from the hearing aid. If the pure-tone hearing threshold is to be used as a guide for selecting hearing aids, it is recommended that people with mild to moderate hearing loss in both ears first choose the ear with greater pure-tone hearing loss.
Perceived degree of hearing impairment. The patient’s perceived degree of hearing impairment or the actual degree of impairment is low. The patient’s urgency for choosing hearing aids is very limited. For this group of patients, a questionnaire can be conducted based on their living environment to help patients correctly understand hearing. The situation also determines whether the hearing aid is suitable.
Hearing compensation needs in different environments and different expectations. The effective benefits that patients can obtain when using hearing aids in different environments are different. Listening to sounds in a quiet environment is often much better and speech intelligibility is much higher than in an environment with loud background noise.
As new users who have never worn hearing aids, they always expect to obtain a high satisfaction rate in both quiet and noisy environments. Comprehensive patient final statements Although patients' expectations are always higher than the actual benefits of hearing aids, most still believe that hearing aids are effective. Therefore, for patients with extremely high expectations, audiology professionals should identify obviously unrealistic expectations and provide correct explanations before making the final decision to purchase hearing aids. With the updated development of hearing aid technology and the application of directional microphone or multi-microphone technology, the speech intelligibility of hearing aids when used in noisy environments is being significantly enhanced to gradually adapt to the higher expectations of patients.
On the one hand, the performance of the patient's hearing condition in various environments will inevitably affect the family members, colleagues and friends around him. Relatives and friends have a great influence on the patient's use of hearing aids. About % of patients who need the help of hearing aids point out that their family members are The initial motivating factors. It is not clear how family attitudes affect patients' actual use of hearing aids. It is believed that positive encouragement from family members is conducive to their continued use, while negative treatment has the opposite effect. Family members are also bound to influence each other. People with hearing loss and hearing aids tend to have the same opinions as their family members. On the other hand, patients who choose hearing aids just to comfort their family members are unlikely to use hearing aids. For example, some patients with long-term tolerance to gradually acquired high-frequency hearing loss were probably first discovered by family members. These patients gradually acquired high-frequency hearing loss while maintaining low-frequency hearing intact. Some of these patients were unaware of the extent of their hearing loss in their family members. The hearing aids chosen with encouragement were not used well.
Speech understanding ability The lower the speech understanding ability, the less likely the patient will benefit from a hearing aid. The degree of hearing loss is not a criterion for a patient's high level of speech understanding. The best approach is to give the patient a speech comprehension test.
Consider aesthetics and ease of operation. Patients of different age groups have different requirements for the aesthetics and convenience of adjustment of hearing aids. Young people always ask for small hearing aids, and old people always emphasize the convenience of adjustment. Of course, some elderly people also require aesthetic considerations. Judging from the population using hearing aids, the rate of young hearing-impaired people using hearing aids is significantly higher than that of older hearing-impaired people. Young hearing-impaired people are more likely to benefit from hearing aids. However, no matter what patients pay more attention to, audiology professionals should still pay special attention to the effect when choosing hearing aids for them. Practice has also proved that most patients clearly emphasize the use effect of the hearing aid rather than the aesthetics and control issues after using the hearing aid for six months. . Of course, there are also some patients who refuse to use a certain type of hearing aid due to certain stubborn requirements.
In some ways, whether a patient ultimately chooses a hearing aid or decides which hearing aid to use depends on the patient's own personality characteristics. For example, people with an extroverted personality benefit more from hearing aids than people with an introverted personality, and optimistic users benefit more from hearing aids than stubborn users.
