Your hearing aid guide on both ears
A hearing aid is a highly technical tool. You can compare it to a computer. Old-fashioned hearing aids are now a thing of the past, because both technology and optics have changed greatly. A hearing aid from today is much more than just a hearing aid. You are using a number of special features. There is also talk of so-called binary.
This guide explains to you what is behind the term binaural hearing aids and how this function supports you in listening. You are very welcome to receive advice from our hearing aid experts on adaptation and selection. Call us or send us a message about hearing loss. Consultation is free of charge.
Compared to current and previous hearing aids
Do you remember the original hearing aid models? These can only amplify the sound received. This is done independently of each other. It works very differently with a modern binaural hearing system. A modern method has been developed in recent years. This is based on natural hearing. That is, for you, that both the left and the right hearing aids are connected by radio and communicate. For you, it means an enormous quality when the hearing systems can communicate with each other. Depending on the initial situation, these intelligently align.
Natural hearing with a binaural hearing aid
The brain manages to filter the language out of the sound and suppress noise. There are signals to understand the language. It is also possible to clearly understand language in an acoustically challenging situation. Do you have a problem with that when there's a lot of noise around you, like in a restaurant or a subway, or... On the bus? If you think you can almost no longer understand your counterpart, you can help yourself with a binaural hearing system. This significantly improves your entire acoustics.
You can also imagine a similar situation, for example, if you are walking with strong wind sounds. You can't have a conversation without a hearing aid. A binaural hearing system automatically checks where the wind comes from and which direction the voice signal is from. Only the right signals are transmitted by radio to the other ear. The disturbing wind noise is effectively suppressed. This works even better with binary hearing systems than with conventional hearing systems. Another typical situation is when you call with one ear. A binaural hearing aid can detect this and simultaneously suppress the sound amplification. At the same time, the sounds from the phone and all signals are sent to the other side. So you can hear what you need to hear on both ears.
The direction of the microphone
With new systems you can hear independently of the viewing direction. Usually the microphone is aligned according to the viewing direction. However, it may happen that you are concentrating from a computer sitting and working. Still, you might want to talk to another person who's beside you or behind you. Older hearing systems are at their limits in such situations. It looks very different with a binaural hearing aid. A binaural hearing aid turns the microphone exactly in the direction from which the signal for the language comes. This means you no longer need eye contact for easy communication.
Orientation in space
Normally, two well-functioning ears are needed to ensure smooth directional hearing and orientation in the room. Finest differences are recognized by the hearing centre. It is distinguished between the left and right ears immediately when signals arrive. This allows you to assign a position in space to the signal and locate it. There is talk of the so-called head-estimation effect. A safe direction assessment is even possible with a binaural system for signal processing.
