Remember, when you had normal hearing there were times when background noise was a problem. It is no different now, even with properly fit hearing aids! The good news is there are circuits and features that help to reduce (or minimise) background noise and other unwanted sounds. In fact, there are research findings that clearly show that digital hearing aids with particular circuits, FM options, and directional microphones can effectively reduce background noises. Please speak to your audiologist about this.

Many early digitally programmable (and even some digital) circuits, which claimed to reduce or eliminate background noise, actually filtered out low frequency sounds. This indeed made the sounds appear quieter, however, not only was the background noise made quieter, but so too, was the speech sound.

Newer ways to reduce background noise are based on timing and amplitude cues and other complex noise processing strategies, which 100% digital hearing aids can process. These methods work, but are not perfect.

Directional microphones are available and are useful as they help to focus the amplification in front of you, or towards the origin of the sound source. Directional hearing aids can offer a better signal-to-noise ratio in difficult listening situations by reducing the noise from the sides or behind you.

In most 100% digital hearing aids, the noise control features help make noise more tolerable.

The best and most efficient way to eliminate or reduce background noise is through the use of FM technology. Please ask your audiologist for advice about this.
