Area of Science:

Artificial Intelligence
Audiology
Signal Processing

Background:

Millions worldwide experience disabling hearing loss, with hearing aids offering only partial compensation.
Understanding speech in noisy environments remains a significant challenge for hearing aid users.

Purpose of the Study:

To develop a deep learning algorithm for selective noise suppression to enhance speech intelligibility.
To restore speech understanding in hearing aid users to the level of individuals with normal hearing.

Main Methods:

A deep neural network was trained on a large dataset of noisy speech signals.
Neural architecture search and a novel deep learning-based intelligibility metric were used for optimization.
The algorithm operates on a single microphone, unlike traditional beamforming methods.

Main Results:

The algorithm achieved state-of-the-art denoising performance across various noise types.
Speech intelligibility was restored to the level of normal-hearing control subjects.
The system demonstrated real-time processing capabilities on a laptop.

Conclusions:

Deep learning-based noise suppression offers a promising solution for improving hearing aid effectiveness.
This technology has the potential for large-scale deployment on hearing aid chips, significantly improving quality of life for the hearing impaired.
