How Auracast Supports Sydney Opera House Visitors With Hearing Loss

We’ve been highlighting the potential of Bluetooth’s broadcast audio technology, Auracast, for quite some time. Recently, this innovation made a groundbreaking debut at the iconic Sydney Opera House, helping individuals with hearing challenges rekindle their enjoyment of live music.

If Auracast hasn’t crossed your radar yet, it’s worth noting that this technology, spearheaded by the Bluetooth Special Interest Group (SIG), employs Bluetooth’s Low Energy (LE) Audio standard. This enables high-quality sound to be transmitted from Auracast-compatible devices to receivers such as hearing aids and headphones. Users can access these dedicated broadcasts via an app or other interfaces.

At CES over the years, we’ve had the opportunity to witness this technology in action, where its applications are expansive. For instance, airport patrons could tune into specific flight gate announcements through their personal headphones, and sports bars could allow fans to select the audio feed of their preferred games being aired on multiple screens.

The Sydney Opera House, teaming up with leading hearing technology firms such as GN, Hearing Australia, and Australia’s National Acoustic Laboratories, has become the inaugural major cultural venue to implement Auracast in its performance spaces, including the Drama Theatre, Playhouse, and Studio venues, with plans to include the larger Concert Hall and other areas soon. Bluetooth LE Audio not only ensures low latency and efficient battery consumption but also boasts remarkable sound quality. Auracast can connect an unlimited number of receiving devices, enhancing the experience for users.

Auracast is now actively enhancing live performances at the Sydney Opera House, allowing users with compatible Auracast hearing aids or headphones to enjoy the shows, thereby fostering a more inclusive atmosphere. This initiative might inspire other venues around the globe to adopt similar technology, broadening access to theatrical experiences.

According to a press release, “Hearing aid users often encounter challenges at live events, where traditional assistive listening systems, like induction hearing loops, are primarily designed for speech and can distort music while limiting seating options to areas with coverage.” The introduction of Auracast seeks to enhance this experience significantly.

For the festival launch at the Sydney Opera House, guests lacking compatible hearing devices were provided with Auracast-compatible Samsung Galaxy Buds3 Pro to experience the technology firsthand. Representatives from Samsung, Google, and the Bluetooth SIG were present to showcase Auracast-compatible products that highlight improvements in auditory experiences within public venues.

Statistics indicate that one in five individuals globally is affected by hearing loss. In the United States, approximately one in eight people (13%, or 30 million people) aged 12 or older experience hearing loss in both ears, as reported by the National Institute on Deafness and Other Communication Disorders. However, advancements are being made to assist those with hearing impairments. The FDA took significant steps in 2022 by allowing the sale of over-the-counter hearing aids aimed at those with mild to moderate hearing loss without the need for a prescription or hearing test. Recently, Apple has introduced hearing aid functionalities in its AirPods Pro 2.

Auracast holds promise for further enhancing experiences for individuals with hearing challenges.

“We are at the forefront of integrating Auracast for hearing aid users to seamlessly connect and enjoy exceptional sound anywhere,” said Peter Karlstromer, CEO of GN. “We take pride in our collaboration with the Sydney Opera House, National Acoustic Laboratories, and Hearing Australia to enable Auracast for performances at this landmark venue – we hope this sets a precedent for others to embrace and advance into the next era of connectivity.”
