, , Experts from Ning'er Hearing Shanghai Putuo Hearing Aid Discount Store said that deaf patients need to choose hearing aids based on their audiograms. The appearance of hearing impairment is first seen in daily life. It is inconvenient to make language calls in their study, work and life, especially when they are not face-to-face. Some positions, such as police, sentries, secretaries, teachers, etc., have very strict hearing requirements. When they have hearing impairment, they are required to wear hearing aids. A greater proportion of people in other occupations or retirees need hearing aids due to hearing impairment. In today's era, the practice of using non-scientific methods to determine personal hearing and blindly purchasing hearing aids from stores has gradually declined, because this does not achieve the targeted effect of wearing glasses. The strict method, which is currently the basic method, is to use a measured pure-tone audiometer to measure hearing, just like visual optometry, and obtain an audiogram that reflects the individual's hearing performance. The curve characteristics on the audiogram can indicate the nature of the hearing impairment. and degree of impairment.
Regarding the degree of hearing impairment, if according to the International Standards Association's regulations on deafness classification, those whose average hearing loss at the four listening test frequencies of , , Hz and Hz does not exceed dB are classified as normal hearing, and dB is classified as mild deafness. dB is moderate deafness, dB is severe deafness, and above dB is total deafness. Although this division is not directly related to hearing aid selection. However, the degree of hearing impairment can be determined by reference, because the output power of hearing aids has a certain specificity. According to the nature and degree of hearing impairment, the direction of selecting hearing aids can be roughly determined, that is, what type of hearing aid to use, to find the corresponding power. with appropriate frequency characteristics.

Classification and production technology of hard ear molds for hearing aids
Ear molds are models of the external auditory canal, which mainly play the role of improving the effect of hearing aids and fixing hearing aids. Ear molds are divided into soft ear molds and hard ear molds. Clinically, the function and production of ear molds play an important role.
The following mainly introduces the production and types of hard ear molds.
Hard ear molds mainly refer to the different materials used. The final ear molds have obvious hardness, while the soft ear molds currently used are quite different. A qualified hard ear mold should be strong, dense, clean, non-toxic, non-absorbent, and tensile. Commonly used hard earmold materials include acrylic (polymerized methyl methacrylate), which requires heat treatment to completely polymerize the material. The finished earmold can be colorless or pink and transparent. This is one of the commonly used materials at present. Polymerized methyl methacrylate Methyl acrylate is a high grade of hard acrylic, non-toxic, suitable for formulators with allergies, and can be made into colorless or pink ear molds. Soft acrylic (polyethyl methyl acrylate) ear mold materials, this polyethylene acid The plastic softens slightly as body temperature rises, is pink in color, and provides a better seal than hard acrylic. At the same time, the material of hard ear molds can also use UV-curable ear mold materials, which are based on vinyl-containing polymers, reactive monomers as cross-linking agents (reactive diluents), and compounds that are easily photodecomposable. Made of photosensitizers, including unsaturated polyester and acrylic polymers, and other auxiliary materials. It is cured by irradiation with ultraviolet light to initiate a free radical reaction. The finished ear mold can be colorless or pink and transparent.
Due to the characteristics of the material, almost all types of hard ear molds can be made, as shown in the figure below, from ordinary to open types, with a wide range of uses.
. Ordinary type: This is a fully enclosed, high-sound-proof, thick earmold. Its purpose is to minimize any sound leakage and prevent acoustic feedback. This type of earmold is used for patients with severe hearing loss and those who use high-gain, high-power hearing aids.
b. Skeleton type: Except for the area near the sound tube, almost all the inside of the ear mold is hollowed out to form a coil shape. This type of earmold has good ventilation and is suitable for patients with moderate to severe disease and hearing aid users who require high-frequency amplification.
.Open type: It can be said that any earmold with a large opening can be called open type, mainly including semi-skeleton type, non-closed type, added hole type, etc. These earmolds are suitable for those who need high frequency. Amplified hearing aid users.
d. Ear canal type: This type of ear mold is similar to the earplugs already available on the market, except that it needs to be customized according to the patient's ear shape and has better sound protection effect. It is only suitable for patients with hearing loss below moderate or those who need hearing aid users who require high-frequency amplification.
Compared with soft earmolds, one of the biggest advantages of hard earmolds is that they can be later acoustically modified and style processed to meet patient needs. These technologies involve ear mold sound tubes, openings, ear canal opening treatment and damping, etc. Experts suggest that any hearing aid fitting shop should have the basic tools for modifying ear molds, including turning heads, sound tubes, ear hooks, etc.

Hearing rehabilitation plan after wearing hearing aids
Users who have just started using hearing aids will encounter a similar problem: the feeling of listening to sounds through the hearing aid is different from the feeling of hearing without the hearing aid. , even if they are familiar family members, their voices sound strange. This condition occurs because the function of your auditory cells slowly declines, leaving your hearing in a state of distortion for a long time. When you return to normal listening, you will inevitably feel a huge change. Therefore, no matter how severe your hearing loss is, wearing a hearing aid for the first time will go through a process of acceptance and adaptation.
In order to help you get through the adaptation period as quickly as possible, we have developed a week-long hearing rehabilitation plan. Please practice patiently and follow the following requirements. If you are still dissatisfied or have other questions, please contact your hearing professional for further contact.
Week 1: Learn how to recognize sounds (including noise) and wear hearing aids for extended periods of time.
Practice location: A quieter, familiar place. For example: home, office, etc.
Practice time: practice at least 2 hours a day. If continuous wear is not possible, it can be done in several stages.
Practice method: Please adjust the volume of the hearing aid to a comfortable level and carefully identify the sounds in the surrounding environment. For example: the sound of the air conditioner fan, footsteps, drawer opening and closing, door closing, typing, faucet running, telephone ringing, car sounds, etc. When you feel tired, lower the volume of your hearing aid or turn it off. Rest for a while before starting to practice. Practice rest in this cycle. As your ability to adapt increases, slowly increase the practice time and shorten the rest time until you can comfortably wear your hearing aid all day long.
Note: This is the first week of learning. The purpose is to familiarize yourself with the daily environment. Please do not rush to use it in noisy public places. Wearing hearing aids must be comfortable. If any discomfort occurs, please take off the hearing aid and rest in time.
Week 2: Learn how to talk to people.
Practice location: Relatively quiet and familiar places, such as offices, parks, etc.
Practice time: Practice for at least 2 hours a day, and wear the hearing aid for at least 10 hours a day.
Practice method: Find a familiar person and practice talking to him alone. The distance between the two people should be close. The other person should talk to you at a normal conversation volume, speaking slowly and clearly. During the conversation, please pay attention to the other person's expression and lips. This will help you understand each word of the other person and correct your pronunciation. When you are comfortable talking to a person, you can appropriately increase the number of people you talk to. Listening in an environment where many people are talking can sometimes be difficult. Please pay attention to distinguish different sounds and try to determine from which direction the sound is coming. Focus on the person you want to listen to, keep practicing, and you'll get better at listening.
Note: This is the second week of study, the purpose is to practice communication with people. You may have difficulty hearing something during the conversation, so please don’t be discouraged. Be sure to start practicing with someone you are familiar with. Please do not rush to practice in noisy public places. If one week of practice time is not enough, please extend it appropriately.
Week 3: Learn to listen in public places.
Practice location: Relatively noisy and familiar places, such as movie theaters, restaurants, supermarkets, etc.
Practice time: Practice for at least 2 hours a day, and wear the hearing aid for at least 10 hours a day.
How to practice: When you are trying to go to a familiar public place, it is best to be close to the speaker and within their line of sight. For example, in a movie theater or opera house, choose a seat in the middle and near the front. Be sure not to sit behind a pillar or object. When dining in a restaurant, try to sit against a wall. This can effectively block noise from behind or to the side (if the hearing aid you are using has a directional function, please choose the middle position. Sit against a wall, otherwise the noise reduction function of the hearing aid will be weakened). Of course, you can also try different positions to achieve the best effect. When talking to people in public places, you must pay attention due to the presence of background noise. If you don't understand something, don't hesitate to ask the speaker to repeat it. This happens to normal people sometimes.
Note: This is the third week of study. The purpose is to practice communicating with people in complex environments. In this kind of environment, normal people will face some problems, so don't put too high demands on yourself. In a complex environment, you will hear a lot of sound signals. Too many signals will interfere with your ability to distinguish. Appropriately turning down the volume may help you. If one week of practice time is not enough, please extend it appropriately.
Week 4: Learn to listen to special sound signals.
Practice location: A relatively quiet and familiar place, such as home, office, etc.
Practice time: Practice for at least 2 hours a day, and wear the hearing aid for at least 10 hours a day.
Practice method: After adjusting your hearing aid, start with news, reviews or TV teaching programs, and gradually move to TV dramas or variety shows with daily conversations, until you can distinguish faster conversations. Under normal circumstances, you can use the behind-the-ear hearing aid function switch to make calls (usually the M setting can also be used to listen to calls well). If the hearing aid has a memory program, usually the first memory will be set as the phone call program, and the program will make calls. Better results. When the earpiece is close to the hearing aid, adjust the angle for best results.
Note: This is the fourth week of learning. The purpose is to practice the use of telephones, TVs and other equipment. Making phone calls and watching TV are one of the most common activities in life. Their common feature is the sound coming from the speakers, and the sound quality of the sound source is very unstable. In addition, communication lines, phone quality and other reasons will also cause call quality to decline, so the listening effect cannot be determined by hearing aids. Please try a different phone or handset for better results.
The above practice process generally takes weeks to complete! Patience, no impatience, and continuous practice are the keys to success! As you become more experienced wearing it, you will find the benefits increasing.

Ning'er Hearing Shanghai Putuo Hearing Aid Discount Store explains the relationship between telephones and hearing aids. Now if hearing-impaired patients need to make calls, new hearing aids can play a big role! For some people, choosing a deep-canal hearing aid, or an open-back behind-the-ear device, allows direct phone use without the need for special equipment or connectors. Other types of hearing aids, as long as they have their own inductive coils or automatic inductive coils, can directly receive phone signals without using a hearing aid microphone, so that the wearer will not be disturbed by acoustic feedback or howling when answering the phone. When using an inductive coil or an automatic inductive coil, you need to choose a phone that is compatible with the hearing aid, or in special cases, you need to add a small magnet attachment to the phone receiver. Some cell phones may cause radio frequency interference, producing static, buzzing, or crackling sounds. However, laws in some countries currently require mobile phone manufacturers to produce several types of mobile phones that are compatible with hearing aids. Therefore, when patients purchase a new mobile phone, they must ask the salesperson to introduce hearing aid-compatible mobile phones. In addition, the U.S. Food and Drug Administration (D) recommends trying various cell phone brands and cell phone types before purchasing so you can determine which hearing aid is best for your phone. Some high-end hearing aids use some new technologies. The wearer can connect the hearing aid to a mobile phone wirelessly through Bluetooth through a very small accessory. The wearer can not only use the mobile phone to make hands-free calls, but also send mobile phone signals to the hearing aid at the same time, so that the wearer Best results are achieved when answering calls with your ears. Various solutions currently designed for using telephones are available for hearing loss patients. From another perspective, if someone has difficulty answering the phone, there may be other hearing problems. Simply using the telephone may not meet the patient's hearing rehabilitation needs. . Therefore, it is necessary to consult an audiologist or doctor to finally determine which solution is most suitable.
