Imagine walking into a crowded airport or noisy restaurant and having your hearing aids instantly connect to the announcement system, TV, or local audio feed. No more straining to catch a gate change. No more guessing what the commentators are saying on the TV above the bar. Connecting to the world around you becomes as seamless and automatic as joining your home Wi-Fi network.
That world is not only possible but is already taking shape through a new Bluetooth technology called Auracast. What is Auracast? Auracast is a feature built on Bluetooth’s new LE audio system, which allows multiple Bluetooth-enabled hearing devices to connect to a single broadcast audio stream (or Auracast transmitter).1 This article will explore what Auracast is, how it works, and why it represents a transformational milestone in accessible audio.
Like FM systems or a telecoil-enabled hearing loop, an Auracast broadcast transmits sound directly into Auracast-compatible hearing aids or assistive listening devices.2 The key difference? Instead of requiring special equipment, Auracast allows users to bring their own hearing devices, whether hearing aids, earbuds, headphones, or cochlear implants—and connect directly to an audio broadcast. This “bring-your-own-device” or “BYOD” model makes connecting to shared audio experiences easier, more accessible, and more discreet for people with hearing loss.3
Functionally, Auracast is like other Bluetooth connections. As a step one, a device that is Auracast-compatible initiates a broadcast. Then, nearby Auracast receivers—such as Auracast-enabled hearing aids—scan for available broadcasts and allow users to connect to their chosen audio feed, through an app or other interface. Once connected, the sound from the broadcast (airport announcements, classroom lectures, event speakers, or even a sports bar TV) streams directly into the listener’s hearing aids or receiving device, providing clear, crisp, and easily accessible audio.4
One of the major benefits of Auracast technology over options like an FM system is that it allows users to bring and use their own Auracast-enabled devices. This extends beyond hearing aids and includes Auracast headphones, earbuds, speakers, smartphones, and TV streamers.
Auracast headphones and Auracast earbuds work just like traditional Bluetooth headphones or earbuds—but they can connect directly to Auracast broadcasts in public or private spaces. This capability is beneficial for people with mild or undiagnosed hearing loss, those with auditory processing disorders, or anyone who struggles to hear speech in loud environments.3
Auracast-compatible speakers can receive Auracast broadcasts and play them aloud. A family using Auracast speakers at home can stream audio from a TV or event, allowing everyone to hear clearly without having to turn the volume up too high.5
Auracast can turn smartphones into powerful audio broadcasters. On compatible Android phones or Auracast iPhones, the device can act as an audio transmitter, sharing whatever is playing on the phone with multiple Auracast-enabled receivers at once.6
Auracast TV streamers bring a whole new layer of accessibility to watching TV. Modern TVs can act as Auracast transmitters, broadcasting their audio to any Auracast receiver in range. This allows users to connect their headphones to the TV audio at home or in public spaces.
Auracast gives users the ability to “unmute their world,” making shared listening experiences more accessible to everyone. This technology enables clearer audio, greater accessibility, ease of use, and more private and cost-effective hearing solutions that everyone, not just hearing aid users, can benefit from.
One of the biggest advantages for hearing aid users is improved access to audio in public spaces. With Auracast, airports, transit hubs, restaurants, theaters, and sporting venues will now have the capability for users to tune directly into the broadcast systems through their hearing aids. Instead of struggling to hear and understand, hearing aid users can quickly, easily, and discreetly access clear and crisp audio.
The benefits of Auracast systems extend beyond just those who wear hearing aids. Anyone with Auracast-enabled earbuds or headphones can tap into these broadcasts, making it helpful for people with undiagnosed hearing loss, auditory processing challenges, or anyone who simply struggles to hear speech in loud environments. This makes accessible listening more approachable for a wider range of users.7
By widening access to shared audio, Auracast helps create a greater sense of inclusion. More people can participate fully in public experiences—no special accommodations are required.
While Auracast technology is still being developed and adopted, connecting to it is meant to feel as familiar and effortless as joining a Wi-Fi network.1 Once your device is Auracast-enabled and you’re in a venue with Auracast audio, you’ll be able to connect in a few simple ways:
Auracast is designed for places where clear, accessible audio matters most— airports, transit hubs, theaters, sports venues, museums, classrooms, restaurants, and more.
More venues are still adopting the technology, which is still growing. Major institutions like the Sydney Opera House have begun using Auracast transmitters, and ABI Research predicts that by 2029, more than 1.5 million public venues will be Auracast-enabled.3 As more venues adopt the technology, Auracast is poised to become a new standard for accessible, high-quality shared audio—making public spaces more inclusive and easier to navigate for everyone.
