Digital circuits can be divided into four categories

August 15, 2007 by Francine Morrissette

1. Basic Digital

This hearing aid has the following characteristics:

  • The volume can automatically adjust itself based on the level of incoming sound.
  • The microphone’s directional mode does not necessarily automatically adjust to your hearing environment. A push-button must be used.

2. Standard Digital

Hearing aids in this category offer:

  • Automatic directional listening adjustment and noise reduction;
  • The hearing aid automatically adjusts to your hearing environment without you noticing the transition from one program to another.

Example: In a restaurant, the digital circuit will adjust the microphone to directional mode and activate the noise reducer, and when you are at home, the microphone will be in omni directional mode and will not activate the noise reducer. All without touching a thing!

3. Mid-Range Digital

This device has all the advantages of the standard and more.
The digital circuit is more sophisticated and incorporates the latest technology.

  • It allows for a clarity of sound that provides for easy and comfortable listening.
  • It includes a 16-channel, high-resolution noise reducer and anti-Larsen interference (reduction of feedback).
  • It provides information on your hearing environment using a computer chip in your hearing aid, allowing for precise adjustments.

The addition of a remote control allows you to use manual programs.
These programs offer an amplification range adapted to your specific listening needs.

Example : You’re attending a play and unfortunately you weren’t able to sit up front. Your listening needs are now different from your everyday needs. In your hearing aid, a “play” setting can be programmed that you can access by the press of a button or by remote control. This remote can be in the form of a remote control device, a watch or a key chain.

4. High-End Digital

This device has all the advantages of the Mid-Range and more:

  • extremely sophisticated digital circuit;
  • reduction of noise from doing dishes or turning pages of a newspaper by the intelligent suppression of sound impulses without affecting the authenticity of these sounds;
  • location of sources of sound;
  • with its 20 adaptive channels, it can focus solely on a person speaking while selectively eliminating multiple sources of noise.
  • optimal hearing in spaces that echo (a church, museum, etc.);
  • reduction of wind noise during outdoor activities (golf, cycling, etc.);
  • automatic volume adjustment adapted to your preferences, according to each listening situation.

In order to choose a hearing aid that is specially designed for your real hearing and communication needs, taking into account the look of the device, don’t hesitate to contact one of the audioprosthetists from theLobe Santé auditive et communication multidisciplinary clinics. They will gladly help you with your choice.

It is recommended to have your hearing tested every two years.
Why? It’s the best way to know if your hearing aid is still right for you and to evaluate its performance.
