Improving Speech Understanding in Noise: A Signia Study Based on Their IX Platform

Signia’s new study on their Integrated Xperience (IX) platform aims to show how well it improves listening in noise and how their multi-stream technology helps with improving speech understanding with Signia IX.

This newly released research, conducted in realistic, noisy group settings, shows just how powerful Signia’s latest technology is when it comes to keeping users connected and confident in the conversation.

The Study: Real-World Group Conversation with Signia IX Hearing in Noise

In a controlled test simulating a real-world group conversation with background noise, participants were asked to understand speech using Signia IX hearing aids versus a competitor device that uses deep neural network (DNN) processing.

Here’s what stood out:

• 86% of participants performed better with Signia IX than the competitor.
• 1.4 dB average improvement in Speech Reception Threshold (SRT)—that translates to a 22% improvement in speech understanding.
• 85% longer engagement time: Participants reported being willing to stay in the conversation longer while using Signia IX.

These numbers matter—because they represent real improvements in how people hear and interact with others in noisy settings.

Why It Works: RealTime Conversation Enhancement

Signia IX is built on a powerful innovation: RealTime Conversation Enhancement, made possible by multi-stream architecture.

This means:

• The hearing aids can track multiple speakers at once, even when they’re moving or speaking over each other.
• The system manages background noise separately from speech signals, keeping voices clear and natural.
• The system dynamically adjusts in real time to changes in the environment, which is crucial for active group settings.

What This Means for Hearing Aid Users

For anyone who’s struggled to follow conversations in restaurants, family dinners, or meetings, this technology is a game-changer. It gives users:

• More confidence in social situations
• Less listening fatigue
• Stronger connection with others

This isn’t just lab testing—researchers simulated group conversations to reflect real-life challenges.
