Bluetooth LE Audio · The next-generation hearing system
Auracast™ & the Auri Mobile System
The biggest leap in hearing accessibility since the induction loop was invented in 1937. Auracast broadcasts crystal-clear, encrypted audio direct to next-generation hearing aids, earbuds and personal receivers. No T-coil required, no field strength to commission, no spillage between rooms.
What Auracast actually is
Auracast is a public broadcast feature of Bluetooth LE Audio, the new generation of Bluetooth ratified by the Bluetooth SIG and being rolled out across hearing aids, earbuds, smartphones and TVs from 2024 onwards. Unlike classic Bluetooth, which pairs one source to one sink, an Auracast transmitter broadcasts to unlimited receivers within range. A single transmitter at the front of a room can serve every Auracast-capable hearing aid in the audience simultaneously.
For end users, joining a broadcast is as simple as scanning a QR code or selecting it from a list. No pairing, no codes, no apps required. For venues, it removes most of the engineering complexity of an induction loop: no perimeter wire, no metal-loss calculations, no field-strength commissioning. And critically, multiple Auracast streams can coexist in the same building (different languages, different rooms, audio description) without crosstalk.
Why this matters now
The hearing aid market is moving fast
Specifying an Auracast-only system today won’t reach today’s hearing aid base. Induction loops still serve the 12 million T-coil-equipped UK aids in circulation. But specifying an induction-only system without Auracast leaves your venue obsolete by the end of the decade. The right answer for any new install is hybrid: T-coil for today, Auracast for tomorrow, designed in from day one.
