Do we need to choose the perfect noise reduction hearing aid?

Because of the characteristics of the hearing aid sound amplifier, noise reduction has become one of its important indicators, otherwise the noise will also seriously interfere with the patient's experience. Some hearing AIDS can work well in a quiet environment, but once you enter a noisy environment, it will be difficult to distinguish the noise from the surrounding complex sound, which is the reason. So, in general, the better the noise reduction effect, the more expensive the hearing aid, so how do we choose?

1）Noise suppression

The noise reduction technology of the hearing aid analyzes the speech and noise, and adjusts the noise and the normal sound that needs to be retained by converting the sound information into a digital signal for processing and differentiation, and turns it into a sound signal for output.

2) Microphone

Multichannel adaptive directivity

This is a feature currently available in mid-to-high end hearing AIDS. A digital hearing aid with directional function or multiple microphones has directional adjustment adaptability. In simple terms, the hearing aid can not only automatically adjust the direction of the microphone, but also confirm the source of the noise and suppress the sound in the direction of the noise. Some high-end models can also track multiple noise sources simultaneously and suppress them at the same time. This is multi-channel adaptive directivity.

Complete noise reduction? It's impossible!

At present, there is no hearing aid that can achieve complete noise reduction. But we must know that even normal people live in noisy environments every day, and noise is a part of our lives. In addition, the better the noise reduction effect, the more expensive the hearing aid, and patients do not need to pursue high-priced hearing AIDS to avoid noise.
