Getting used to wearing a hearing aid takes time as our ears and brain need to adapt to it and learn how to hear again. Meanwhile, new users inevitably have some doubts and questions on how their new device works or how to clean and maintain it.

Frequently asked questions about hearing aids 

This article is a beginner’s guide to hearing aids and aims to answer some of the most frequent doubts on these hearing devices:

How do hearing aids work?

The microphone in the hearing aid picks up voices and sounds and converts them into an electric signal that is transmitted to the processor, which is capable of amplifying them according to each patient’s specific needs and level of hearing loss. Then, the hearing aid receiver converts the amplified electric signal into an acoustic signal and transmits it to the ear canal.

What is the difference between a hearing aid and an amplifier?

According to the AEMPS (Spanish Agency of Medicines and Medical Devices), sound amplifiers are electronic devices that simply boost or amplify background noise and are not designed for people with hearing loss. On the other hand, hearing aids are specific medical devices that amplify and process sounds to compensate for hearing impairment.

How are hearing aids cleaned?

A hearing aid is comprised of several parts, the majority of which require regular cleaning with a soft, dry cloth. We recommend avoiding contact with water, excessive humidity and sources of direct heat. Never use chemical products, such as strong detergents, dissolvents or alcohol, on your hearing aid. To keep the device in optimum condition, it is important that it undergoes regular maintenance services at your local hearing centre.

Why do I need two hearing aids?

Although many people think it is normal to use a hearing aid in one ear, hearing loss commonly occurs in both. Therefore, your hearing aid specialist is likely to recommend the use of two hearing aids to restore stereophonic hearing. This type of binaural hearing aid restores a wider, more natural hearing range.

How do I adjust the volume on my hearing aids?

The volume on your hearing aid adjusts automatically. The level of amplification depends on the individual’s hearing loss, and every device amplifies quieter sounds more than loud sounds. However, some models also feature manual volume control.

What are the different types of hearing aids?

Not long ago, we posted an article on our blog about when it is time to have a hearing aid fitted and the types of hearing aid available. Your hearing aid specialist will advise you on the functions and features of the different types of hearing aid and will recommend the one that best suits your specific needs.

Can I use a mobile phone if I am wearing a hearing aid?

Yes. Thanks to the IoMT and wireless hearing aids, telephones and television sets can be heard directly through hearing aids.

Can I wear my hearing aid in the shower?

As we mentioned above, this is NOT advisable. Your hearing aid is an electrical device, so any water or moisture it comes into contact with can damage its internal circuits.

How can I repair my hearing aid?

The best option is to visit your local hearing center and request technical support from a hearing aid specialist. Never try to repair your hearing aid yourself – it is a complex technological device and contains delicate precision components.
