A new milestone for Auracast™ broadcast audio, and what it means for hearing aid users
|
The hearing aid industry has reached a significant milestone. Today, all of the industry’s big five hearing aid manufacturers — Sonova, Demant, GN, WS Audiology, and Starkey (which collectively account for approximately 90 percent of the global hearing aid market) — offer hearing aids that support Auracast™ broadcast audio ([hearinglos…ournal.com], [pandahearing.com], [biologyinsights.com]).
This achievement is more than a technology milestone. It is a strong endorsement of the industry’s commitment to open standards, interoperability, and accessible audio experiences. When the companies responsible for most of the world’s hearing aids align behind a single global standard, it sends a clear signal: Auracast™ broadcast audio has become a foundational technology for the future of hearing accessibility.
Why this matters
For decades, people with hearing loss have relied on a wide range of assistive listening technologies, many of which required specialized infrastructure, dedicated receivers, or proprietary solutions. While these systems have helped millions of people, they often create fragmented experiences and limited interoperability. Auracast™ broadcast audio has changed that.
Auracast™ solutions enable audio broadcasts that can be received directly by compatible hearing aids, earbuds, headphones, and assistive listening receivers. Instead of requiring venue-specific hardware or proprietary receivers, Auracast™ broadcast audio creates a standardized ecosystem that easily allows hearing aid users to receive assistive audio in public spaces without relying on additional equipment provided by the venue.
The fact that all big five hearing aid manufacturers now support Auracast™ broadcast audio demonstrates confidence in the technology’s ability to deliver a consistent, interoperable, and scalable accessibility solution.
Addressing a growing global need
According to the World Health Organization (WHO), nearly 2.5 billion people worldwide are projected to have some degree of hearing loss by 2050, representing approximately one in every four people on the planet. More than 700 million people are expected to require hearing rehabilitation services ([who.int], [who.int]).
As populations age and hearing loss becomes increasingly prevalent, improving access to high-quality audio in public spaces is no longer a niche requirement. It is a global accessibility challenge.
People need reliable access to announcements in airports and transit hubs and clear audio in houses of worship, lectures in universities, performances in theatres, commentary in stadiums, and conversations in healthcare settings. Auracast™ broadcast audio offers a standardized platform for delivering these experiences directly to personal listening devices, including hearing aids.

From hearing aids to hearing access
Support from hearing aid manufacturers is only one side of the equation. The other is making Auracast™ broadcast audio available in the places where people live, learn, worship, travel, and gather. That momentum is becoming increasingly visible, as venues around the world put Auracast™ broadcast audio into action. Auracast™ deployments now span clinics, houses of worship, stadiums, theatres and entertainment venues, and universities.
Some deployments demonstrate the scale and variety of that growing ecosystem. In New Zealand, Stadium Taranaki, a 21,000-seat outdoor venue, has deployed an Auracast™ solution, while the Isaac Theatre Royal in Christchurch is bringing the technology to a venue that hosts theatre, concerts, comedy, and dance. In Japan, MOVIX, a cinema chain operated by Shochiku Multiplex Theaters, has 20 locations nationwide. Other deployments range from the SONEO Hörgeräte in Saarland, Germany, to hearing healthcare provider Resonate Health in New Zealand, illustrating how Auracast™ broadcast audio is moving into very different types of public and professional spaces.
Together, these deployments show how the hearing aid milestone connects to a much broader shift. As more compatible hearing aids reach consumers and more locations deploy Auracast™ solutions, the technology can help extend hearing access beyond the device itself and into the environments where people need to hear and participate.
Making accessibility mainstream
While Auracast™ broadcast audio is transforming accessibility for people with hearing loss, its impact extends far beyond traditional hearing assistance.
Historically, assistive listening technologies have often been associated with specialized or medical devices. Auracast™ broadcast audio helps change that paradigm by leveraging the same Bluetooth® technology ecosystem used every day by billions of consumers. Rather than requiring dedicated receivers or venue-specific equipment, Auracast™ broadcasts can be accessed through hearing aids, smartphones, earbuds, headphones, speakers, TVs, and other compatible consumer electronics devices.
This broad ecosystem support is important because it helps reduce the stigma sometimes associated with hearing assistance technologies. When the same audio broadcast can be received by a hearing aid, a pair of wireless earbuds, or a smartphone, accessibility becomes part of a mainstream consumer experience rather than a separate solution reserved only for people with hearing loss.
Major consumer electronics brands have already embraced Auracast™ broadcast audio across a growing range of products. As adoption continues to expand, consumers will increasingly expect the ability to discover and join Auracast™ broadcasts wherever they go, whether they are listening to a public announcement in an airport, following a lecture at a university, enjoying a performance at a theatre, or hearing commentary in a stadium.
Auracast™ broadcast audio is…emerging as a universal audio platform that bridges the worlds of hearing healthcare and consumer technology, advancing a future defined by interoperability, inclusion, and accessible audio for everyone.

The support of the big five hearing aid manufacturers, combined with adoption by leading consumer electronics brands, demonstrates that Auracast™ broadcast audio is not simply an accessibility feature. It is emerging as a universal audio platform that bridges the worlds of hearing healthcare and consumer technology, advancing a future defined by interoperability, inclusion, and accessible audio for everyone.
The power of global standards and interoperability
The most important aspect of this milestone is the hearing assistance it provides for those with hearing loss, but what this milestone represents for interoperability is also incredibly significant. Accessibility technologies have historically suffered from fragmentation. A venue might support one system, while a user’s hearing device supported another. This created confusion, additional costs, and barriers to adoption.
Auracast™ broadcast audio helps solve this challenge through a global, standards-based approach. A hearing aid from one manufacturer can connect to an Auracast™ infrastructure deployed by another company, creating a seamless experience for users. That level of interoperability benefits everyone.
- People with hearing loss gain greater access to public spaces
- Venue operators can deploy a single standards-based solution
- Device manufacturers can innovate while maintaining compatibility
- The broader ecosystem can scale more efficiently
The support of all big five hearing aid manufacturers reinforces the industry’s belief that accessibility works best when built on open, interoperable standards.
Looking ahead
The convergence of industry support, device availability, and venue deployment marks an exciting new chapter for hearing accessibility.
The industry has crossed an important threshold. Auracast™ broadcast audio is no longer a future promise. It is becoming a global accessibility platform, backed by the world’s leading hearing aid manufacturers and enabled by the power of Bluetooth® technology.
With every major hearing aid manufacturer embracing Auracast™ broadcast audio, millions of hearing aid users now have a path to connect directly to Auracast™ enabled environments. As deployments continue to expand across churches, clinics, theatres, universities, stadiums, transportation hubs, and entertainment venues, the vision of universally accessible audio moves closer to reality.
As the number of people living with hearing loss continues to grow, global standards and interoperability will play an increasingly important role in ensuring everyone can hear, participate, and engage with the world around them. With the big five now supporting Auracast™ broadcast audio, that future is already taking shape.
