Auracast enabled hearing aids

The future of connectivity and assistive listening technology is here. Auracast™ broadcast audio transforms audio experiences with the latest Bluetooth® technology and Auracast enabled hearing aids.


What is Auracast and Bluetooth LE Audio?

Watch Thomas Olsgaard, Principal Engineer at GN Group, run through the benefits of this breakthrough technology. Thomas is one of the original industry engineers who worked with Bluetooth SIG to establish the standard,1 working for many years to help develop the technology that enables hearing aids to connect via Auracast. GN has created the industry’s first hearing aid to connect to both Bluetooth LE Audio and Auracast broadcast audio.

Bluetooth Low Energy (LE) Audio is the next generation of Bluetooth wireless connectivity

You probably already use Bluetooth technology in your daily life, streaming music, TV audio or calls. The new Bluetooth LE Audio offers the clearest sound, lowest latency and lowest battery consumption for all-day streaming. In the next few years, it is expected there will be 3 billion Bluetooth LE Audio enabled devices including mobile devices, computers and TVs.2

Auracast broadcast audio gives great new possibilities to stream audio at public places

Auracast broadcast audio, the next generation of assistive listening technology, is being rolled out in public places globally and in everyday devices to transform audio experiences and make hearing inclusive. Join Auracast experiences near you with Auracast enabled hearing aids and compatible devices.2

Auracast and Bluetooth LE Audio technical explanations

The new LC3 codec is the new standard for the wireless transmission of audio from transmitter to receiver systems.  

A codec compresses data to transmit it with minimal energy consumption and computational effort. Formerly, these codecs have not been optimised for the specific requirements of hearing aids, and as a result, hearing aids manufacturers have developed and added their own proprietary protocols. 

This has led to recurring connection issues across different manufacturers, as a consistent compatibility between hearing system firmware, smartphone operating systems, and Bluetooth protocols could not be guaranteed.  

Additionally, LC3 is the new standard codec for audio transmission for all products using Bluetooth LE Audio. This will result in significantly fewer compatibility limitations in the future. 

The new LC3 codec and Bluetooth LE Audio were developed in collaboration with the Consumer Electronics industry and hearing aid manufacturers. Bluetooth LE Audio is optimized for low power consumption, high audio quality, and very low latency.  

With Bluetooth LE Audio, it will be possible to establish direct connections from the television, laptop or other Bluetooth 5.3 compatible devices, to hearing aids.
Auracast is the next-generation Assistive Listening System (ALS). It can co-exist with other technologies, like telecoil. It has a broader transmission, is easy to install, and enables people to sit wherever they want to hear.

Auracast opens up entirely new possibilities for streaming audio in public places. 

Listening is simple: users select the Auracast stream they want to listen to on their mobile device, and the hearing aid or an Auracast-enabled device receives the signal, just like selecting a WiFi-hotspot.  

It can also be done by clicking on a physical button at the location or by scanning a QR-code. Hearing aid wearers get a high-quality signal in several places, as the installation of an Auracast streamer is cost-effective and straightforward. 

Not only can lectures at a conference, university, school, or museum be streamed to hearing aids, but also the sound from silent or quiet TVs at bars, in buses or in stores.  

In public places such as a train station or airport, announcements about trains or flights will be transmitted directly to the hearing aids, so everyone gets the information they need. 

Even in the cinema, Auracast is a great improvement for hearing aid wearers. The audio signal of the movie is streamed directly to the hearing aids, no matter where they’re seated. So, follow the action, and don’t miss out.
