Auracast Transforms Cathedral Acoustics With Unmatched Audio Clarity

5/15/2025

Samsung Electronics is bringing people together through sound. The company will showcase the capabilities of Auracast technology by partnering with hearing-aid provider GN on a groundbreaking event at St. Paul’s Cathedral in London on May 16 to mark Global Accessibility Awareness Day (GAAD). Attendees wearing Galaxy Buds3 Pro or GN hearing aids will utilize Auracast, which allows a single audio source to broadcast to multiple receivers simultaneously and embark on a unique journey of shared listening.

What’s Happening

Auracast microphones and transmitters will broadcast audio directly into participants’ Galaxy Buds3 Pro or GN hearing aids, decreasing background noise to enhance clarity. A select group was given the opportunity to discover the potential of Auracast – at a pilot event on May 1.

“The Auracast experience with the tour guide was amazing,” said one participant. “Ordinarily I wouldn’t be able to join in with the tour because I would be unable to hear properly, but today it was completely different. This technology allowed me to hear everything so clearly so I didn’t miss a word.”

Auracast and LE Audio

What is LE Audio?¹ Introduced in 2022 by the Bluetooth Special Interest Group, Low Energy (LE) Audio is an updated standard for Bluetooth technology. It enables more power-efficient and higher-quality wireless transmission of audio from a broadcasting device to a receiver such as from a smartphone to earbuds.

Samsung has led efforts to increase LE Audio compatibility for mobile devices and hearing aids. Since 2022, the company has been pushing for the expansion of LE Audio, introducing 360 Audio Recording ² and adopting Auracast through the Buds2 Pro software update.

What is Auracast? Auracast³ is a feature of LE Audio that allows broadcasting from a compatible audio source⁴ to multiple supported audio receivers^5,⁶, including earbuds and hearing aids. Think of it as turning your phone into a radio station.

Benefits of Auracast

Shared Audio Experiences: As Auracast enables simultaneous audio streaming to multiple devices, listeners can enjoy a unified and enriched experience whether using ear buds or a compatible hearing aid. This represents a significant leap from traditional Bluetooth technology, which allows only one device to pair with an audio source.
Seamless Audio Handoff: When moving from your smartphone to TV, or from public to private spaces, sound stays with you —as you don’t have to manually pair your device to each new audio source.
Audio Clarity Anywhere: Auracast reduces background noise as audio is directly broadcast into your ears, providing a clearer sound experience. This is particularly beneficial in venues with loud echoes such as cathedrals and museums.
Personalized Sound: Whether in a museum, a stadium, an airport or at home, Auracast allows you to tailor audio settings to your preferences. This customization ensures that users with varying hearing abilities can enjoy optimal clarity.
