Frequently asked questions

  • I have good hearing, but I am experiencing difficulties understanding speech. Why?

    One of the most common hearing problems is the inability to understand speech. Although this type of problem can be caused by certain physical, cognitive and neurological conditions, it is most commonly caused by hearing loss. As “normal” hearing loss usually implies different types of damage to a whole specter of sounds, there is selective deterioration in hearing in certain areas of hearing. This usually translates as more damage in the area of high frequencies responsible for understanding speech, leading to problems understanding human speech. In order to clear up your dilemmas, call us at Bontech and get a free hearing check!

  • What kind of batteries do hearing aids require?

    Most hearing aids require specially designed batteries that provide power consistently throughout their lifespan. This is really important for hearing aids. There are four types of hearing aid batteries: 10A, 312A, 13A and 675A, all of them are zinc-air batteries. It is extremely important to only use batteries suggested by the hearing aid manufacturer in order to ensure the proper functioning of the aid and avoid unwanted effects.

  • Is it better to have a hearing aid in one or both ears?

    Considering the effect on health and life quality, when a person suffers from hearing loss in both ears, they should always wear two hearing aids. We hope that awareness about the great benefits of wearing two hearing aids will improve in the future (in ophthalmology this shift happened a long time ago, which is why no one wears a monocle these days). Certain functions are completely disabled if a person has good hearing in only one ear, such as locating sounds in space, while most functions are severely diminished when only one hearing aid is used – such as understanding speech in a noisy environment, following a conversation with several collocutors, etc. Using only one aid can only be exhausting for the ear. It is important to emphasize that hearing aids help preserve your hearing, but only in the ears where you use them.

  • What are the advantages of higher-quality hearing aids? Why are some aids more expensive?

    Higher-quality aids use better components – high quality microphones, amplifiers and speakers. This does NOT mean that these aids will produce a louder sound, but that they will produce a more pleasant one. The tendency in manufacturing has always been to try to approach the human hearing system as accurately and as closely as possible. Newer hearing aids serve to do much more than just amplify sound, the aim is to make the information that is being sent to the brain as similar as possible to those transmitted by the healthy ear.

  • I have a perforated eardrum, can you help?

    Patients with perforated eardrums are recommended to use custom-designed ear plugs in order to prevent water and dirt from entering the middle ear. Since even a few drops of water can create problems, universal ear plugs are not recommended, as they cannot provide the protection of the type offered by individually designed ear plugs at Bontech.
    My child has a tube inserted in the eardrum, what can I do to protect it from water? The answer again is individually designed ear plugs. It is very important that they are custom-made due to the specific anatomical features of the ear canal of a young person. Children are also recommended to use new ear plugs every year, because growing can cause the shape and size of the ear canal to change with time.

  • I spend a lot of time in noisy spaces. What can I do to prevent potential damage to my hearing?

    Protection from loud noise is extremely important for protecting hearing. Hearing damage and tinnitus (ringing in the ears) are just some of the difficulties caused by such external influences. At Bontech, we produce two types of ear plugs for protection from noise. On type cancels noise, while still allowing outside sounds to filter into the ear at a lower intensity (these ear plugs are fit for musicians, DJs, frequent club goers, etc.). The other type seals the ear canal completely, offering maximum protection and minimal sound entry – these ear plugs are appropriate for sleeping, loud workplaces, etc.

  • Is making an impression of the ear painful and/or damaging?

    Making an ear impression is entirely safe and painless. The process itself takes about five minutes (depending on what material is being used). A swab of cotton wool or a sponge attached to thread is first inserted in the ear, and then the ear canal is filled with a special liquid using a special syringe. After the liquid hardens, the impression is pulled out of the ear and sent for further processing.

  • Can hearing aids recover hearing?

    Although the use of hearing aids stimulates and protects the functioning of the whole hearing system, it can recover a loss of hearing.

  • What is the life expectancy of hearing aids?

    The hearing aid itself does not have a limited lifespan. But to ensure your aid will function properly and for a long time, it is important to maintain it as best as possible. Maintenance primarily involves keeping the aid dry and clean, as well as cleaning and drying it regularly.

  • How are ear implants / ear plugs designed? Do they chafe?

    The process begins with an ear examination, and once it is established that there are no further impediments, an impression of the ear is made. This procedure is completely painless and harmless, and it takes about five minutes. Your next step is to pick up the ordered product once it is done. Our job only begins here, however. Impressions are adapted for scanning, and are inserted into the 3D scanner, which makes a digital, three-dimensional image with high precision. This image is then processed and adapted for production on industrial, high-tech 3D printers. After they come out of the printer, the implants and ear plugs have to go through two to three more steps of processing and control quality before being delivered to you. This process ensures the highest protection, precision, and comfort of use.

You can get your hearing checked at any of Bontech's 30 retail stores.
