In their daily work with hearing-impaired people, hearing aid fitters often encounter this situation: the same type of hearing aid has different effects on different people. Some people say they can socialize normally, while others still can't hear clearly. Some people have mild hearing loss and poor listening effects, while some people have severe hearing loss and good listening effects... Why does this happen?

We need to understand some simple hearing knowledge. The human ear can be divided into three parts: the outer ear, the middle ear, and the inner ear. If the sound is transmitted through the air, it will enter the inner ear from the outer ear and the middle ear, and then be received by the brain. This is called air conduction. Sound can also enter the inner ear directly into the skull by vibrating the skull, which is called bone conduction. Hearing care workers perform pure tone tests on a daily basis to test air conduction hearing and bone conduction hearing.

Based on the audiogram, we can classify hearing loss:

• 1. If only the outer ear and middle ear have problems, it is conductive hearing loss.
• 2. If only the inner ear and the auditory nerve have problems, it is sensorineural hearing loss.
• 3. If there are problems in the outer ear, middle ear, and inner ear, it is mixed hearing loss.

As an auxiliary hearing device, the main function of hearing aids is to amplify sound. For users with conductive hearing loss, the lesions of the outer ear and middle ear cause the sound entering the inner ear to become smaller. After wearing hearing aids, this part of the smaller sound is amplified and enters the inner ear again, which will give a good listening effect.

Mixed hearing loss Secondly, the wearing effect of users with sensorineural hearing loss is relatively worse, because their hearing lesions are located behind the complex inner ear and auditory nerve. No matter how the sound is amplified, it needs to be received and transmitted by the inner ear. If the inner ear is diseased, the sound information cannot be fully received, and the phenomenon of hearing but not hearing clearly will occur.

In addition to the type of hearing loss, the duration of each person's hearing loss and the time of intervention will also affect the effect of hearing aid wearing. For example:

1. If you find that your hearing is declining, you will start to intervene and treat it in time, and the hearing aid will have a better listening effect.

2. If the user has hearing impairment or even prelingual deafness in the early stage, and starts wearing hearing aids after a long time, there will be resistance and poor hearing. However, you can't be anxious about this kind of situation. You need enough patience to carry out hearing rehabilitation training. As the brain continues to receive sound, the effect of hearing aids will also appear.

Therefore, even if it is the same hearing aid, different hearing loss types, hearing loss duration, and whether timely intervention will affect the wearing effect of hearing aids.

We know that many people have hearing impairments for various reasons, which affects communication. Hearing aids are electronic devices that can be used to help people with hearing loss improve their hearing and communication abilities.

1. Improve hearing

Hearing aids can amplify sounds and help people with hearing loss better perceive and understand the sounds around them, including speech sounds, environmental sounds, etc. This helps improve their quality of life and social participation.

2. Protect residual hearing

Long-term hearing loss may lead to further hearing loss. Wearing hearing aids can stimulate the auditory nerves by amplifying sounds, maintain the brain's sensitivity and discrimination to sounds, thereby protecting residual hearing and preventing further hearing loss.

3. Prevent cognitive decline

Hearing loss not only affects verbal communication, but may also lead to cognitive decline, such as Alzheimer's disease. Wearing hearing aids can improve hearing conditions and avoid cognitive decline caused by hearing problems.

4. Improve social and emotional health

Hearing loss may affect people's social and emotional health, leading to increased loneliness and reduced social interaction. Wearing hearing aids can help people with hearing loss communicate better with others, establish effective interpersonal relationships, reduce loneliness, and improve social and emotional health.

5. Improve quality of life

Hearing loss may affect people's daily life, such as watching TV, listening to the radio, participating in social activities, etc. Wearing hearing aids can help people with hearing loss enjoy these activities better and improve their quality of life.

In short, wearing hearing aids has many benefits for people with hearing loss, including improving hearing, protecting residual hearing, preventing cognitive decline, improving social and emotional health, and improving quality of life. Hearing aids improve hearing and communication abilities for people with hearing loss. As long as hearing loss exists and affects daily communication, you can consider wearing hearing aids. What type of hearing aid to choose needs to be determined based on personal hearing condition and the advice of hearing care professionals.

Although both are auxiliary devices designed to improve certain functions of the human body, their principles and goals are significantly different.

Vision problems can essentially be solved by changing the mechanical conduction pathway, while most hearing-impaired people who wear hearing aids face sensorineural problems, and hearing problems are far more complicated than vision problems.

Glasses are a device used to correct vision. Its main function is to correct optical errors so that the wearer can see more clearly. Glasses change the refraction path of light through lenses, which are specially designed to correct different vision problems. Once the glasses are fitted, people can often see a clear world immediately.

The principle of hearing aids

A hearing aid is a device that amplifies sound. It collects sound through a microphone, converts it into an electrical signal, then amplifies the signal through an amplifier, and finally plays the sound through a speaker (receiver).

The goal of a hearing aid is to help people with hearing impairment hear better. However, hearing aids cannot directly change the refraction path of light like glasses. It needs to adjust parameters according to each person's hearing condition to achieve the best effect.

For example, from the classification of hearing loss, it can be seen that the cause of hearing loss is very complex. Each hearing-impaired person has his or her own hearing loss curve, cause, listening preference and other personalized characteristics. The cause of conductive hearing loss is in the outer ear and middle ear. The damaged parts of sensorineural hearing loss patients are in the inner ear and auditory nerve. The inner ear hair cells cannot regenerate. If the hearing loss is caused by damage to the inner ear hair cells, hearing aids cannot "cure" it. The lesion of patients with mixed hearing loss combines the conductive and sensorineural hearing loss.

The hearing aids fitted by the audiologist for you do not simply amplify the sound, but accurately compensate according to the hearing curve of the hearing-impaired person to achieve the effect of being able to hear and hear clearly.

The difference between the principles and goals of hearing aids and glasses

In general, although glasses and hearing aids are both auxiliary devices designed to improve certain functions of the human body, their principles and goals are significantly different. Glasses correct vision by changing the refraction path of light, while hearing aids help the hearing-impaired hear clearly by amplifying sound.

Hearing impairment requires scientific selection of hearing aids, which has been recognized by most people. However, it is more necessary for hearing-impaired patients and their families to conduct scientific hearing rehabilitation training under the professional guidance of hearing aid fitters, so as to achieve better hearing rehabilitation effects.

First of all, scientific training should be carried out in accordance with the natural laws of human rehabilitation training, and it is not easy to rush for success, otherwise it may further damage the residual hearing or cause the user to experience symptoms of auditory pain and dizziness. Preliminary adaptive rehabilitation training should be carried out according to the four-week training method. Usually, the adaptation period for most hearing-impaired patients is 3 to 6 months.

Secondly, the rehabilitation training plan should be set realistically according to the individual differences of hearing-impaired patients. For example, the size of the first debugging data should be adjusted according to the actual feelings of the hearing-impaired patients, and how long it takes for the second debugging should also be planned according to the actual wearing time, adaptability to the environment, and actual needs for sound of the hearing-impaired patients.

In addition, the following hearing rehabilitation training methods should be followed to improve the hearing effect.

1. Classification training

The training method should be designed in the order from easy to difficult and from simple to complex. It mainly cultivates the ability of hearing-impaired patients to distinguish syllables and phonemes in syllables. In the whole process of auditory rehabilitation training, classification training only takes a short time, generally 10 to 15 minutes a day in the early stage. For hearing-impaired patients with severe hearing loss, they have lost a lot of ability to learn sound information. Therefore, in classification training, speech sounds are usually given only one syllable or word at a time. Therefore, hearing-impaired people can focus on practicing the characteristics of speech sounds.

2. Comprehensive training

Comprehensive training is to provide speech sounds to hearing-impaired patients in a normal voice way. For example, through conversation or storytelling. The purpose of training is to develop and improve the auditory, visual or auditory communication skills of hearing-impaired people. The training materials generally include meaningful sentences, paragraphs or words. It is also necessary to make the sounds they hear correspond to the sounds made by actual objects to understand and feel, and there is a process of re-understanding and learning sounds. In comprehensive training, we mainly focus on the overall picture of speech, such as semantics, syntax, contextual cues and other content training. In fact, in auditory rehabilitation training, most of the time is spent on comprehensive training. It should mainly simulate the actual communication situation according to the needs of hearing-impaired patients, with the focus on allowing hearing-impaired patients to understand the information, even if they cannot accurately perceive every sound. During the auditory rehabilitation training, hearing-impaired patients should give feedback information so that the speaker can understand what content is perceived by the hearing-impaired patients and what content is lost.

3. Practical training

Practical training is to teach hearing-impaired patients how to obtain the necessary information for communication by changing the communication environment during communication. The advantage of this training is that it can train hearing-impaired patients to use listening skills and conversation skills, which is very useful in actual communication.

Hearing-impaired patients, their families and hearing aid fitters all hope to see a good listening effect, which is a win-win situation. Therefore, both parties need to work together, trust and support each other, and select a more suitable hearing aid product for hearing-impaired patients through the scientific matching skills and matching methods of hearing aid fitters, and then according to the professional debugging and adaptive rehabilitation guidance plan of hearing aid fitters, and finally, with the trust and support of hearing-impaired patients and their families, active wearing and adaptive rehabilitation training can promote hearing-impaired patients to achieve a good result and situation.
