Hearing is an important feeling in a person's life. When hearing loss or hearing loss occurs, correction is necessary. To solve these problems, hearing aids have been invented based on modern technology. This is a great solution to a problem for an elderly person or child. In this article we will describe which device to choose and how to use it. But before using the device, it is advisable to consult a doctor.

How the hearing aid works
Hearing devices are designed to restore lost hearing. At the same time, they filter out unnecessary noise and consist of the following components:
- reading sensor;
- signal amplifier;
- the broadcast receiver.
Connoisseurs of acoustic equipment are familiar with its simple operation algorithm. But even those who do not know it are not difficult to understand this. When sound waves in the air hit, they fall on the microphone of the device and are converted into an electrical signal. The data from the microphone goes to the amplifier, which sharpens the performance. Then the broadcast goes to the receiver (speaker), which plays the sound into the auricle. This sound is far superior to the original source. It follows that with poor hearing, the problem is partially considered solved.
What are the types
Hearing devices vary in design, function, size, and model. Advanced, for example, implantable and micro-aural ones are selected only by specialists. But with other models there should be no problems and you can choose them yourself, taking into account the doctor's recommendations. After using the device, a person suffering from hearing loss perceives sound almost the same as a healthy person.
All hearing aid models are divided into 2 types:
- Analog. Such models are not expensive and easy to use. The disadvantages include the functionality of the volume control. Turning it in one direction or another leads to a change in the level of not only speech or music, but also other noises. The main mechanism contains a microphone with an amplifier, as well as a speaker. Frequencies do not adjust to ambient noise and human conditions. Such devices do not correct sound, are bulky in size, but simple to operate. In some cases, their use is unhealthy.
- Digital: The device works like a computer, which consists of a digital processor, microphone and speaker. The incoming sound is picked up by the microphone and converted into digital code. Thus, it is able to separate noise and speech. Further, the information is processed taking into account the characteristics of the user. But before that, you need to make careful adjustments. The main advantage of such models is that loud sounds become softer, and unnecessary noises are not heard at all. Digital hearing aids are subject to certification and are classified as medical.
Important! Digital hearing aids should not be used by people with chronic ENT conditions.
How to choose
According to doctors, people with hearing impairments need to approach the criteria for choosing an assistive device armed with useful information. Since the manufacturers of some models can facilitate or aggravate the perception of sounds.Experts will help you learn about the variety of devices and their characteristics. You can understand the rating of quality models, as well as find out a lot of useful information in this review.
Selection errors can lead to impaired hearing. It can also lead to distrust of hearing impaired people to hearing aids.
What to look for when choosing?
- The model must be certified and pass all necessary checks. I would like to point out right away that household amplifiers are not considered hearing aids.
- The hearing aid must be customized. Failure to do so may result in negative effects after incorrect volume setting.
Types of devices by design
The design of the devices also has differences and is divided into:
- Behind the ear. The common design is popular with users due to its affordable price. The device fits behind the ear and is medium in size. A conductive tube is inserted into the ear canal and transmits amplified sound and holds the device. High power and a wide range of settings are the features of such devices. There are earbuds at the end of the sound-conducting tube, which is convenient for the physiological structure of the ears.
- Pocket. Powerful in every way. The device consists of 2 parts: a speaker and a box with technical equipment. They use such a device only if other options fail.
- Intra-aural. Compact and suitable for people suffering from discomfort from an existing problem. Invisible, as they are located inside the ear, and reproduction is natural. It may seem that the person is just listening to music. Such models can cause discomfort when wearing, as they press on the ear and disrupt blood circulation. Depending on the physical condition, it can cause migraines.
- Implantable. The design works on the principle of sound transmission through the skull bone. This implant is inserted under anesthesia. The principle of action lies in vibration through the auditory nerves. The device is suitable for people with an infection in the ear canals.
- Framed for glasses. This is an air conduction type, looks like regular glasses. The equipment is located in the temples of the glasses, from which the speakers protrude, and are inserted into the ears. It is better to use tight earmolds to avoid stretching the ear canal.
Useful Tips
Each hearing aid model has its own advantages and disadvantages. For example, in-the-ear, mini-behind-the-ear and in-ear models are prohibited for use with a perforated eardrum and chronic otitis media. The popularity of models is associated with technical characteristics. To obtain the necessary information, you need to carefully study the instructions for use or consult a doctor. Power - must meet the needs of the device for full hearing compensation. A sufficient supply of energy must perform its functions for several years, since hearing changes cannot be predicted.
- The channel is an important characteristic, thanks to which you can adjust the sound gain. More channels contribute to better speech and sound intelligibility.
- Compression is a sound amplification system. Improving it provides greater comfort in use. Quiet sounds become louder and harsh sounds become quieter. But the natural sense of loudness is not compromised.
- Noise Reduction - Provides better intelligibility and comfort in noisy environments. There are models that do not suppress noise, but enhance speech.
In addition to the listed characteristics, there are others that are responsible for sound quality, speech intelligibility, smoothing of impulse sounds in a quiet room, etc.
Choosing a manufacturer
When choosing devices for amplifying audio signals, it is necessary to give preference to devices of Russian production and European quality, since they are experienced and also the best manufacturers. These include Italian, French, American companies that provide product warranties and good service. There are branches all over the world, including in Russia. If your choice fell on a little-known manufacturer, then there is no guarantee that there will be no problems with operation. Adjustment and recommendations for use can only be provided by qualified employees, not just sellers.
