How AI Noise Reduction Works in Hearing Aids

AI noise reduction in hearing aids uses advanced algorithms to improve speech clarity and reduce background noise in real time. Unlike older models with static filters, these devices analyze sounds, classify environments, and adjust settings automatically. Here’s how it works:

• Real-Time Sound Analysis: AI scans and categorizes sounds like speech, traffic, or background chatter.
• Speech Detection: It isolates and enhances human voices while suppressing distractions.
• Dynamic Noise Filtering: Noise levels are adjusted as environments change, ensuring clear conversations.
• Personalization: Devices learn user preferences over time, tailoring performance to individual needs.

Modern hearing aids like the Phonak Audéo Sphere Infinio and Starkey Omega AI 24 process millions of sound samples per second and offer features like voice prioritization, app-based controls, and extended battery life. Regular updates, professional tuning, and proper maintenance further enhance their performance, making everyday listening more effortless.

How AI Noise Reduction Works

AI noise reduction combines three core processes: real-time sound analysis, training on a wide range of audio samples, and ongoing personalization. At its core, it uses deep neural networks (DNNs) to evaluate incoming sounds, separate speech from background noise, and adapt to your unique listening preferences over time.

Real-Time Sound Analysis and Classification

The magic of AI noise reduction lies in its ability to instantly analyze and categorize sounds. Unlike traditional devices that use static filters, AI-powered hearing aids rely on algorithms to process multiple sound properties all at once.

Take the Phonak Audéo Sphere Infinio as an example. Equipped with its DEEPSONIC AI chip, it performs billions of operations per second. This allows it to quickly enhance speech clarity while minimizing background noise.

The system evaluates sound characteristics like frequency patterns, amplitude changes, and timing to classify sounds into categories such as human speech, traffic, or background chatter. This rapid classification ensures smooth transitions as you move through different environments, setting the stage for effective training on real-world audio.

Training with Real-World Sound Samples

AI noise reduction’s effectiveness depends on extensive training with millions of real-world audio samples. Before these systems reach users, they are exposed to sounds from various environments – restaurants, busy streets, offices, and homes. This repeated analysis helps the AI differentiate between meaningful sounds and distractions.

Challenging environments like a crowded restaurant, where background music, clinking dishes, and overlapping conversations coexist, are a key focus. The system learns to amplify the voice you want to hear while suppressing others. This robust training ensures reliable performance, whether you’re sipping coffee in a bustling café or enjoying the quiet of a library.

Continuous Learning and Personalization

What sets AI noise reduction apart is its ability to adapt to your preferences over time. Unlike traditional devices with fixed settings, AI-powered hearing aids evolve based on your listening habits and interactions.

Companion apps allow users to fine-tune sound settings, teaching the device to better cater to their needs. Over time, the system becomes more intuitive – prioritizing familiar voices and adjusting to the environments you frequent.

This personalization even extends to your daily routines. For instance, if you prefer softer noise reduction during morning conversations but stronger filtering in noisier evening settings, the system learns and adjusts automatically. The result? A hearing experience that feels natural and improves the more you use it.

AI Noise Reduction: Step-by-Step Process

AI noise reduction is a fascinating process that happens in mere milliseconds. Here’s a closer look at how it works, broken down into four key steps.

Step 1: Scanning and Classifying the Sound Environment

The process begins with the hearing aid scanning and analyzing your surroundings. Using its microphones, the device captures audio from all directions. AI algorithms then process this data, analyzing frequency patterns, volume levels, and timing to identify the environment – whether it’s a quiet library, a bustling restaurant, a busy street, or an office. For instance, the Phonak Audéo Sphere Infinio uses its DEEPSONIC AI chip to excel at this task. It doesn’t just classify the environment but also pinpoints the direction of sounds, making it easier to separate speech from background noise. Once the environment is classified, the system shifts its focus to isolating speech signals.

Step 2: Identifying Speech Signals

After understanding the environment, the AI zeros in on human speech. It uses advanced pattern recognition to analyze vowel and consonant patterns, natural speech rhythms, and contextual clues to enhance the voice you want to hear. Devices like Starkey’s Edge AI are great examples of this step in action. Its neural processing unit can differentiate the target voice from competing background chatter. When users activate features like “Edge Mode+” with a double tap or through the app, the system further prioritizes speech over noise.

Step 3: Dynamic Noise Filtering and Amplification

Once speech is identified, the AI dynamically filters out noise and amplifies the sounds you need. Unlike older hearing aids that use static filters, AI systems adjust in real time based on the specific sounds in your environment. The Phonak Audéo Sphere Infinio demonstrates this with its “intelligent noise control”, which can “lock onto voices with pinpoint precision.” Lab tests even show that this device improves the signal-to-noise ratio (SNR) by 10 dB, making it one of the top performers for speech clarity in noisy settings.

Step 4: Real-Time Adaptation to Environmental Changes

The final step is all about adapting on the fly. As you move from, say, a quiet room to a crowded street, the AI instantly reclassifies the environment and adjusts its settings. There’s no need to manually switch programs – the device does it for you. Over time, it even learns your preferences. For example, if you frequently adjust the volume in certain scenarios, the AI remembers and applies those settings automatically in similar situations. This constant adaptation ensures you always get the best sound quality, regardless of how quickly your surroundings change. Devices like those from Injoy Hearing highlight this seamless, real-time performance, making AI-driven hearing aids a game-changer for users.
