The aim is to improve speech intelligibility
The difference between existing noise reduction strategies reflects a difference in focus. Some systems aim to make the sound as comfortable as possible to listen to for the user. Other systems aim to provide improved speech perception.
The primary aim of the Speech Enhancer in Widex hearing aids is to provide the highest possible speech intelligibility while still providing a comfortable listening experience.
The Speech Enhancer uses the standardised measure of the Speech Intelligibility Index (SII) to work out the optimal gain for speech understanding in the current listening environment, taking the client’s hearing loss into account.
