For people with hearing loss, the biggest challenge isn’t just hearing well at home.
It’s staying connected in busy, noisy environments like airports, theaters, and churches.
Until now, following a conversation in a crowded space or hearing a public announcement often meant frustration and missed moments.

This technology is transforming how personal listening devices and countless other gadgets connect to the world around us.
Here’s what you need to know about this exciting leap forward. It’s making real-world hearing clearer and more accessible than ever before.
Understanding Auracast: What It Is and Why It Matters for Better Hearing
Auracast is a broadcast audio feature of Bluetooth LE Audio, which was introduced in 2022.
Unlike traditional Bluetooth, which needs a direct, one-on-one connection between devices, Auracast enables a single audio source to broadcast sound to multiple nearby devices simultaneously. This includes your listening solutions.
Think of it like joining a Wi-Fi network. Your devices can simply “tune in” to public or private audio streams without any complicated setup.
The hearing technology industry played a key role in shaping Auracast from the very beginning. It recognized its huge potential as an accessibility tool. Because Auracast is designed to work not just with personal sound tools but also with TVs, smartphones, and public sound systems, it’s ready for widespread use.
It goes far beyond older assistive technologies like telecoils.
Here are three real-life examples of how Auracast is already making these aids smarter and life easier:
Public Spaces Transformed: Theaters, Churches, and Venues
Before Auracast, many public venues relied on telecoil systems for assistive listening.
While helpful, telecoils often had limitations, sometimes poor sound quality, specific seating areas where they worked best, and often confusing setup processes for users.
Auracast changes everything. In equipped venues, you can simply tap a button on your device’s app, like the ReSound app’s Auracast Assistant, to join a live audio stream. The result? Clear, direct sound delivered right to your listening solution, no matter where you’re sitting. No extra equipment is needed. No awkward requests to venue staff.
One great example is the Sydney Opera House. In 2025, it became the first major cultural institution to put Auracast into action across multiple venues. Now, visitors with personal hearing instruments can enjoy crystal-clear performances effortlessly.
In the U.S., adoption is just beginning. As commercial Auracast transmitters become more widely available, theaters, places of worship, and conference centers are expected to quickly follow suit.
Announcements in Airports and Stations
Traveling with hearing loss has always been stressful.
Whether it’s trying to catch a muffled gate change announcement in a noisy airport or an urgent update at a train station, these environments consistently rank as some of the hardest for people to hear clearly.
Auracast solves this by allowing airports and other public spaces to broadcast real-time announcements directly to your listening devices. Imagine hearing clear boarding calls or schedule updates delivered straight into your aids. This happens without the frustration of asking strangers for help or straining to hear over constant background noise.
This isn’t a far-off dream, it’s already starting to happen. As public spaces install Auracast transmitters, accessibility and independence for travelers with hearing loss will improve dramatically. This will make journeys less stressful and more predictable.
Personalized and Seamless Audio at Home
Auracast isn’t just for public places, it’s a game-changer at home, too.
Streaming TV audio to personal sound tools used to often require costly extra accessories and complicated setups. What’s more, if you decided to change your device brand, you often had to replace all that extra equipment.
Auracast simplifies this entirely. Compatible smart TVs, tablets, and computers will soon be able to broadcast directly to your listening solutions. This lets you stream audio without delays, extra dongles, or complicated pairing processes.
For couples, this technology solves a very common issue. One partner needs the TV louder, while the other prefers it quieter. Now, the device user can stream audio directly at their preferred volume. The TV plays at a comfortable level for everyone else in the room.
While Android phones like the Pixel 8 have already started supporting Auracast, iPhones are expected to follow soon. Fortunately, listening device manufacturers like ReSound have developed smart ways to bridge this gap. This allows users to find and join Auracast streams through the ReSound app, even before full smartphone support becomes universal.
ReSound’s Leadership: Paving the Way for Auracast
ReSound has been a leader in hearing device connectivity for many years. They were, in fact, the first to connect directly to iPhones way back in 2014.
Today, they’re leading again with Auracast, showing their commitment to pushing the boundaries of accessible hearing technology. Auracast is available in ReSound’s latest listening solutions, including the Vivia AI, Savi, and Nexia product families.
ReSound also created the first listening device app with an Auracast Assistant. This lets users find and join audio broadcasts effortlessly, no matter what smartphone they use.
This dedication ensures that their users are among the first to experience the benefits of this new revolution.
The Wireless Future: What This Means for Your Hearing
Auracast is not a distant promise, it’s already here. It is actively transforming how people with hearing loss engage with the world.
From public performances to busy travel hubs, and from cozy living rooms to large conference centers, this technology is delivering clearer, more accessible sound wherever you go. It represents a significant step towards a truly connected sound environment.
If you’re considering new personal listening instruments, actively look for Auracast compatibility to future-proof your listening experience. This ensures you’ll be ready for the expanding world of broadcast audio.
