The Royal National Institute for Deaf People (RNID) has published findings from a study of how Auracast broadcast audio performs for railway announcements, and reported that participants found announcements substantially clearer with it than without. The testing was carried out at Bristol Temple Meads station in March 2026 and funded by the Motability Foundation.
RNID invited ten people of varying ages who use hearing aids or cochlear implants to use Auracast in both quiet and noisy station conditions. Only one participant already had Auracast built into their hearing device; the rest were loaned a neckloop receiver or a smartphone dongle to connect. The main finding saw participants understanding announcements substantially better through Auracast, while most could not understand the same announcements over the station's public address system without it. Participants also valued being able to move freely around the platform rather than standing in one spot to catch announcements, and described the experience as less stressful.
The suggestions for improvement centered on implementation rather than the technology itself. Participants wanted it to be easier to find and connect to an Auracast broadcast, and wanted better balancing between the broadcast audio and the sounds picked up by their hearing device microphones. RNID's recommendations included that train operators add signage and website information so people know Auracast is available, use an audio alert at the start of announcements, and ensure adequate coverage across stations and trains. It also recommended that technology developers integrate Auracast controls into existing hearing aid, cochlear implant, and smartphone app controls so connecting is more seamless.
