Poor audio announcements have long been accepted as part of travelling by rail. Whether caused by background noise, different vehicle acoustics or hearing impairments, important passenger information is not always received as intended.

At the same time, passenger expectations are changing. Accessibility, multilingual communication and a better passenger experience are becoming increasingly important for operators and manufacturers alike.
Auracast™, based on Bluetooth® LE Audio, has the potential to fundamentally change how audio information is delivered in public transport.
Instead of relying exclusively on conventional loudspeakers, announcements can also be transmitted directly to compatible hearing aids, smartphones and headphones. This creates an additional communication channel that complements existing passenger information systems rather than replacing them.
The implications go far beyond accessibility.
Passengers could receive clearer announcements in noisy environments. Different language streams could be offered simultaneously. Temporary information, disruption messages or service updates could become more personal and easier to understand.
For rail operators, this opens new possibilities to improve passenger communication while building on existing infrastructure.
Henning Franke, Head of Hardware Manufacturing at cn-mobility, said:We believe Auracast™ represents one of the most exciting developments in passenger information for many years. It has the potential to make audio communication more accessible, more flexible and more passenger-centric than ever before.
As with every emerging technology, widespread adoption will take time. Device availability continues to grow, industry standards are maturing and the rail sector is beginning to explore practical implementation scenarios.
For us, however, one thing is already clear:
Auracast™ is far more than another wireless audio technology. It offers an opportunity to rethink how passenger information reaches people—not by replacing existing systems, but by extending them with a new digital communication channel.
The future of passenger information will not only be seen on displays and heard through loudspeakers. Increasingly, it will be delivered directly to the passenger.
