AI and Hearing Clarity 101
May 21, 2025
Published by Phonak Team
AI (artificial intelligence) is transforming hearing aids - making conversations clearer with less effort and empowering you to live more confidently than ever. But not all hearing aids with AI deliver the same real-life benefits. Here's what you need to know to get the best hearing experience possible.
What are AI Hearing Aids?
Hearing devices use AI to automatically adapt to your ever-changing environment in real-time - providing you with a seamless and effortless listening experience wherever life takes you.
Hearing aids can offer more benefits of AI with DNNs.
A DNN, or Deep Neural Network, is a type of artificial intelligence that learns like your brain does. When applied in hearing aids, a DNN can help your hearing aids recognize and focus on the sounds that matter (like speech) while reducing what doesn't (like background noise).
Just like your brain learns from experience, a powerful DNN learns by recognizing patterns. In the case of hearing aids, the more real-world, high-quality sounds the DNN is trained on - and the more powerful the processor behind it - the better it becomes at helping you hear clearly, even in the most complex, noisy environments.
