Join in, intuitively

Joining an Auracast™ broadcast

will be as easy as 1, 2, 3.

1. Searching

One way to find and join an Auracast™ broadcast will feel very similar to how you search for and connect to Wi-Fi networks today.

A simple scan of a QR code will allow you to join an Auracast™ broadcast effortlessly.

A tap is now all it takes to pay. In much the same way, tap-to-hear could make access to Auracast™ broadcasts quick and easy.

How it works

Any number of Auracast™ receivers within range can connect to a nearby Auracast™ transmitter to listen to the broadcast.

STEP 1

An Auracast™ transmitter begins an Auracast™ broadcast that includes advertisements, which provide Auracast™ assistants with information about the broadcast (e.g. name, content, codec configuration, etc.), as well as one or more audio streams (e.g. left and right stereo audio streams).

STEP 2

Auracast™ assistants scan for Auracast™ advertisements and provide a user interface (UI) to enable users to select an Auracast™ broadcast to join, similar to the UI commonly used to connect to Wi-Fi networks in public spaces.


STEP 3

Once an Auracast™ broadcast is selected, the Auracast™ assistant provides the Auracast™ receiver (e.g. headphone, earbud, hearing aid, etc.) the information it needs to join the Auracast™ broadcast. 



For assistive listening

Auracast™ broadcast audio and assistive listening

At all life stages, communication and good hearing health connect us to each other, our communities, and the world. While current assistive listening system (ALS) technologies, such as inductive loops, have been providing great benefit to people with hearing loss, they suffer from a number of challenges that have limited their deployment, including poor quality, high cost, and lack of privacy. The Bluetooth SIG worked closely with the hearing aid industry to define and introduce the next generation of assistive listening system technology, Auracast™ broadcast audio.

The next generation of assistive listening is here

The hearing aid industry turned to Bluetooth® technology to overcome the challenges of traditional assistive listening systems (ALS) with Auracast™ broadcast audio. See why this new Bluetooth capability will make broader deployment and increased availability of ALS for people with hearing loss possible, while also expanding applicability of these systems to consumers with all levels of hearing health.

Audio accessibility
for all

Auracast™ broadcast audio will become an advanced, new assistive listening system that will be significantly easier and lower cost to deploy while offering higher audio quality and greater privacy. Overcoming the challenges of traditional ALS technologies using a familiar, proven technology ubiquitous in most consumer audio devices will provide the added benefits of enabling broader deployment and increased availability of ALS for people with hearing loss, while also expanding applicability of these systems to consumers with all levels of hearing health.

Public locations – including conference centers, movie theaters, transportation centers, places of worship, and more – will deploy Auracast™ broadcast audio to promote better living through better hearing for everyone.
