Hearing aids: A professional guide to selection and use in Ukraine 2025

About 10% of the world's population faces various forms of hearing impairment. This is not just medical statistics, but the reality of millions of people who experience difficulties in communication, work, and building social connections every day. Modern hearing aids have changed the approach to hearing correction, transforming from simple sound amplifiers into high-tech digital systems with artificial intelligence and wireless capabilities.

Technological progress in audiology allows for effectively compensating for most types of hearing loss. However, it is important to understand that successful correction requires not only high-quality equipment but also a professional approach to diagnostics and adjustment. That's why it's important to turn to specialized centers where you can buy a hearing aid with a guarantee of proper selection and individual adjustment to the specific needs of the patient.

Types and degrees of hearing impairment

Understanding the nature of hearing impairment is the first step to its effective correction. Medical classification distinguishes several main types of hearing loss, each of which requires a specific approach to compensation.

Conductive hearing loss

This type occurs due to mechanical obstacles in the path of sound waves to the inner ear. Causes can include: inflammatory processes of the middle ear, accumulation of sulfur, damage to the eardrum, or damage to the auditory ossicles. Conductive hearing loss often responds to medical or surgical treatment, but in cases where such methods are not possible, hearing aids provide excellent results due to their ability to amplify sound sufficiently.

Sensorineural hearing loss

The most common type, associated with damage to the hair cells of the inner ear or the auditory nerve. Such damage can be caused by age-related changes, prolonged exposure to noise, the use of ototoxic drugs, viral infections, or genetic factors. Sensorineural hearing loss is usually irreversible and requires the constant use of hearing aids.

Mixed hearing loss

A combination of conductive and sensorineural components requires a comprehensive approach. In such cases, both medical intervention and further use of hearing aids may be indicated to achieve the best result.

Degrees of hearing loss

Classification by severity helps determine the necessary power of the hearing aid:

• Mild degree (26-40 dB): Difficulty perceiving quiet speech, whisper, and sounds at a distance. Conversations in noisy rooms become problematic.
• Moderate degree (41-55 dB): Normal loudness speech is perceived only at close range. Phone conversations are difficult, the need to increase the volume of the TV.
• Moderately severe degree (56-70 dB): Understanding speech is possible only with a loud voice and close range. Group conversations are almost impossible.
• Severe degree (71-90 dB): Perception of only very loud sounds. Conversation is possible only with the use of a very loud voice near the ear.
• Profound degree (over 91 dB): Only certain extremely loud sounds are perceived. Cochlear implantation or powerful hearing aids may be required.

Classification of modern hearing aids

The choice of the right type of hearing aid depends on many factors: the degree of hearing loss, the anatomical features of the ear canal, the patient's lifestyle, and their aesthetic preferences. Modern manufacturers, such as the Danish brand Widex, offer a variety of solutions for each specific situation. Before making a choice, it is recommended to carefully study the catalog of hearing aids to understand the full range of available models, their technical characteristics, and price categories.

Behind-The-Ear (BTE) hearing aids

This is the most common and versatile type, placed behind the auricle. The body contains all electronic components and microphones, and sound is transmitted to the ear through a tube and ear mold.

Advantages of behind-the-ear models:

• Suitable for all degrees of hearing loss, from mild to profound
• Powerful acoustic capabilities due to the larger size of the speaker
• Longer battery life due to the ability to use larger power elements
• Ease of maintenance and battery replacement
• Ability to connect to auxiliary devices
• Lower probability of contamination with earwax
• Convenient for people with limited fine motor skills of the hands

Disadvantages: noticeable on the ear, possible discomfort when wearing glasses, prone to sound curling with improper adjustment.

Receiver-In-Canal (RIC) hearing aids

A modern modification of behind-the-ear hearing aids, where the speaker is placed directly in the ear canal, which significantly reduces the size of the behind-the-ear part and improves sound quality.

Features of RIC systems:

• Compact and aesthetic design
• More natural sound due to the location of the speaker closer to the eardrum
• Smaller occlusion effect (feeling of ear congestion)
• Convenience during prolonged wearing
• Versatility for different degrees of hearing loss

In-The-Ear (ITE) hearing aids

Made individually according to the impression of the auricle and completely placed in it. The body contains all the components and fills the outer part of the auricle.

Characteristics of ITE models:

• Individual manufacturing ensures a perfect fit
• Absence of external elements behind the ear
• Natural use of the anatomy of the auricle to collect sound
• Suitable for mild to moderate degrees of hearing loss
• Convenience when using the phone

Completely-In-Canal (CIC) hearing aids

The most inconspicuous type, which is completely placed in the ear canal and practically invisible from the outside. It is made individually according to the exact impression of the patient's ear canal.

Advantages of CIC devices:

• Maximum aesthetics and discretion
• Protection from wind due to deep location
• Natural perception of the direction of sound
• No effect on wearing glasses or hats
• Minimal risk of damage during physical activity

Limitations: suitable only for mild to moderate degrees of hearing loss, require good fine motor skills for installation, shorter battery life, not suitable for people with very narrow ear canals.

Key technologies of modern hearing aids

Modern hearing aids are a complex combination of acoustics, digital signal processing, and wireless technologies. Understanding the basic functions will help you make an informed choice.

Digital sound processing

Unlike analog predecessors, digital hearing aids analyze the sound environment in real-time and automatically adapt to different acoustic situations. The processor divides the sound into several frequency channels (from 4 to 48 depending on the class of the device) and adjusts the amplification separately for each channel according to the patient's audiogram.

Directional microphone systems

Multi-channel directional microphones allow the device to determine where speech is coming from and focus on it, while suppressing background noise from other directions. This is critical for understanding conversations in noisy environments: restaurants, public transport, on the street.

Noise reduction systems

Modern algorithms are able to distinguish between speech and noise, automatically reducing the level of unnecessary sounds without affecting speech intelligibility. The most advanced models use artificial intelligence to identify the type of acoustic environment and select the optimal processing parameters.

Feedback suppression

The anti-whistling (curling) technology automatically detects and eliminates acoustic feedback that occurs when amplified sound gets back into the microphone. This allows you to use more amplification without discomfort.

Wireless connection

Most modern models support Bluetooth connection with smartphones, tablets, and TVs. This allows you to:

• Stream phone calls directly to hearing aids
• Listen to music and audiobooks in high quality
• Adjust settings via mobile app
• Receive voice notifications and GPS directions
• Switch programs with a simple touch to your smartphone

Artificial intelligence and machine learning

The latest models, such as Widex EVOKE, use AI to learn based on user preferences. The device remembers which settings you choose in different situations and automatically applies them in the future. In addition, anonymized data from all users is analyzed in the cloud, allowing the system to constantly improve.

Rechargeable batteries

Modern lithium-ion batteries provide a full day of operation after 3-4 hours of charging. This is convenient, cost-effective, and environmentally responsible compared to disposable batteries.

Criteria for choosing a hearing aid

The right choice of hearing aid depends on a comprehensive assessment of many factors. Let's consider the most important ones in more detail.

Degree and configuration of hearing loss

An audiogram is a graphical representation of hearing thresholds at different frequencies. It shows not only the overall degree of hearing loss but also which frequencies are most affected. For example, high-frequency hearing loss (the most common option) requires a device with the ability to strongly amplify in the high-frequency range with moderate amplification of low frequencies.

Individual needs and lifestyle

An active person who is often in a variety of acoustic environments will need a model with automatic program switching and a powerful noise reduction system. For an office worker who spends a lot of time on phone calls, Bluetooth connectivity is critical. Musicians need devices with a special music program that does not limit the dynamic range.

Anatomical features

The size and shape of the ear canal can limit the choice. Very narrow or non-standard shaped canals may make it impossible to use in-canal models. Excessive earwax production is also an indication for behind-the-ear models, as in-ear devices are prone to contamination.

Cognitive and physical abilities

It is more difficult for elderly users with limited fine motor skills to work with miniature in-ear devices. In such cases, it is better to choose larger behind-the-ear models with large controls. The presence of hand tremors or coordination disorders is also an indication for easier-to-use models.

Budgetary considerations

Hearing aids are classified by technology levels: basic, standard, advanced, and premium. Basic models provide quality amplification in quiet environments but have limited noise reduction capabilities. Premium devices offer the most complex processing algorithms, many automatic programs, and the best sound quality in complex acoustic situations. It is important to find a balance between needs and financial capabilities.

The process of professional selection of a hearing aid

Successful hearing aids are not just the purchase of a device, but a complex process that requires qualified medical support. Let's consider each stage in detail.

Stage 1: Hearing Diagnostics

Professional diagnostics includes several mandatory procedures:

• Otoscopy: Examination of the outer ear and eardrum to detect structural abnormalities, inflammation, blockages, or other pathologies.
• Tonal threshold audiometry: Determination of hearing thresholds at frequencies from 125 to 8000 Hz separately for each ear through air and bone conduction.
• Speech audiometry: Assessment of speech intelligibility at different loudness levels, which allows predicting the effectiveness of hearing aids.
• Tympanometry: Study of the function of the middle ear and the mobility of the eardrum.
• Registration of otoacoustic emission: Assessment of the function of the outer hair cells of the cochlea, which helps differentiate types of sensorineural hearing loss.

Stage 2: Consultation and selection

Based on the diagnostic results, the audiologist, together with the patient, determines the optimal solution. The following are discussed:

• Type of device according to the degree of hearing loss
• Required level of technology
• Aesthetic preferences
• Functional needs (Bluetooth, number of programs, etc.)
• Budgetary framework

Most modern clinics provide the opportunity to test several models in real conditions before making a final decision.

Stage 3: Individual adjustment

After selecting the model, the device is precisely programmed to the patient's specific audiogram. Modern adjustment systems use validated methods (NAL-NL2, DSL v5), which take into account:

• Age-related features of sound perception
• The difference between the ears with asymmetric loss
• Experience of previous hearing aids
• Individual tolerance to loud sounds

Adjustment is always carried out using verification - an objective measurement of sound parameters directly in the patient's ear canal using a special probe.

Stage 4: User training

The specialist explains in detail:

• Correct insertion and removal of the device
• Replacing or charging batteries
• Daily care and cleaning
• Using controls and switching programs
• Working with the mobile app (if available)
• Connecting to the phone and other devices

Stage 5: Adaptation period

The first weeks of using a hearing aid are an adaptation period when the brain relearns how to process sound information. It is critical:

• Wear devices daily for more and more time, gradually increasing the duration
• Start with quiet environments and gradually move to more complex ones
• Visit follow-up appointments for precise adjustment
• Do not expect instant recovery of "normal" hearing

Usually, full adaptation takes from 3 to 6 months, during which 3-4 visits are made to correct the settings.

Care for hearing aids

Proper care significantly extends the life of the devices and ensures stable sound quality. Let's consider the main aspects of maintenance.

Daily care

• Cleaning: Wipe the device every evening with a soft dry cloth. Remove accumulated earwax with a special brush or tool that comes with the kit.
• Battery check: For battery-powered models, check the charge and replace the elements in time. For rechargeable ones, put them on charge every night.
• Inspection: Make sure the sound channel is not blocked by sulfur and the microphone holes are clean.

Regular maintenance

• Filter replacement: Wax-repellent filters need to be changed every 1-3 months, depending on individual sulfur production.
• Tube replacement: In behind-the-ear devices, the tubes harden and turn yellow over time. They should be changed every 3-6 months.
• Earmold update: Individual earmolds last 2-5 years, after which their acoustic properties or fit may deteriorate.

Professional maintenance

Once every 6-12 months, professional deep cleaning and technical inspection at the service center are recommended. Specialists use special equipment for:

• Vacuum removal of sulfur from all channels
• Checking acoustic parameters
• Diagnostics of electronic components
• Software update

Preventing damage

• Humidity: Remove devices before showering, swimming, or intense physical activity. Use drying capsules with moisture absorbent for overnight storage.
• Temperature: Avoid prolonged exposure to extreme temperatures. Do not leave devices in the sun, near heaters, or in a frozen car.
• Cosmetics: Apply hairspray, perfumes, and creams before installing the devices. Chemicals can damage microphones and the body.
• Mechanical damage: Store devices in a protective case when not in use. Install and remove them over a soft surface in case of falling.

Common mistakes when choosing and using

Understanding typical mistakes will help avoid disappointment and make the most of the capabilities of modern hearing aids.

Mistake 1: Purchase without professional diagnostics

Ordering a hearing aid online without prior audiometry and consultation leads to ineffective correction. Universal sound amplifiers do not take into account the individual configuration of hearing loss and can even worsen the situation, excessively amplifying frequencies where hearing is preserved and insufficiently where it is reduced.

Mistake 2: Delaying the decision

The longer a person lives with reduced hearing, the more difficult the adaptation to the devices. The brain "unlearns" to process certain sounds, and restoring this ability takes more time. In addition, prolonged sensory deprivation can lead to cognitive impairment.

Mistake 3: Expecting instant results

Many users are disappointed when the sound seems "unnatural" or "too loud" immediately after installing the devices. This is normal — the brain needs time to readjust. It is important to go through the full cycle of adjustments and not give up on the devices prematurely.

Mistake 4: Use only in "important" situations

Inconsistent wearing of devices significantly slows down adaptation. The brain needs regular sound stimulation for effective learning. It is recommended to wear devices all the time you are awake, except when it is impossible (shower, swimming).

Mistake 5: Improper care

Neglecting daily cleaning and regular maintenance leads to premature breakdowns. Most service calls are related to problems that could have been avoided with proper care.

Economic aspects and state support

Price categories

The cost of hearing aids in Ukraine varies from 10,000 to 150,000 hryvnias and more depending on:
