930003Berlin (dpa/tmn) – music or information to many Being able to broadcast listeners at the same time has many advantages. Just think of classic broadcasting. The Bluetooth Special Group (SIG), responsible for the development of the radio standard of the same name, has now concreted its plans for spatially limited audio broadcasts to theoretically any number of Bluetooth headphones or speakers.

The new feature, called Auracast, is expected to be written into the Bluetooth LE Audio specifications and released in the coming months.

Auracast means: share and listen

when the first smartphones, notebooks, televisions or systems Auracast will come onto the market is still difficult to estimate. They could then share their sound wirelessly with nearby Auracast-enabled headphones, speakers, or hearing aids.

Anyway, the Bluetooh SIG doesn’t just see potential in the private sphere for Auracast, but also in public space. The technology can make what was previously mute audible on headphones, for example: the sound from television sets and displays at train stations, squares, airports, in sports halls, restaurants or waiting rooms.

In addition, audio transmissions or announcements, which previously only ran via loudspeaker systems, can also be received directly with Auracast-enabled Bluetooth headphones or hearing aids. For example at conferences or in the cinema.
