Problems with the perception of sounds can be congenital or acquired after injuries, diseases or age-related changes. In each case, the question of selecting a hearing aid requires an individual approach. This is a medical device, not a household gadget, so a thoughtless choice may not solve the problem of hearing loss.
Types of hearing aids
According to the sound processing technology, analog and digital hearing aids are distinguished. Analogue models amplify the sound, but have limited adjustment options and do not always provide sufficient speech quality. Digital devices convert sound into a code, process it with software and adapt it to the needs of a specific patient.
According to the placement method, digital models are behind-the-ear, in-the-ear and in-the-canal models. Over-the-ear devices often have the most power and advanced functionality. In-ear and in-canal models are made taking into account the anatomy of the ear, so they are more compact and less noticeable.
How to determine which device is needed?
The selection should be made by a hearing specialist after a comprehensive examination. During the diagnosis, the degree of hearing loss, the range of frequencies that the patient perceives worse, the cause of the disorder and accompanying factors are determined. Lifestyle, age, work, communication needs and health are important.
A hearing aid for an elderly person
For elderly patients, not only efficiency is important, but also ease of daily use. Digital hearing aids are often the best solution: they are easier to install, maintain and adjust. At the stage of adaptation, discomfort may arise from sharp sounds or noises, so control settings are required.
A hearing aid for a child
Children with congenital or early hearing impairment need not only hearing compensation, but also support for speech, social adaptation and learning. Usually, the specialist recommends a digital multi-channel model, which helps to hear a wider range of sounds and to form the correct speech skills.
Where to buy a hearing aid?
It is safest to choose a hearing aid in a medical facility or a specialized center that has audiologists and fitting equipment. It is worth checking the certificates, warranty, documents for the device and the qualification of the specialist.
Frequently asked questions
Can you buy a hearing aid without a doctor? It is possible to buy, but the effectiveness of such a decision is doubtful. Without audiometry and adjustment, the device may not meet the real needs of the patient.
Are hearing aids harmful? Properly selected and adjusted medical hearing aids do no harm. Audio amplifiers that are not medical devices can be dangerous.
On which ear is the device installed? In many cases, binaural prosthetics — devices for both ears — are optimal. This improves speech intelligibility and helps determine the direction of sound.
