Real-world listening: Auracast™ broadcast audio’s clearer sound is driving meaningful progress
|
To explore how Auracast™ broadcast audio performs across a variety of acoustic conditions, we invited several dozen participants with hearing loss to Japan’s first Auracast™ film screening.
One cochlear implant user recently shared their experience using Auracast™ broadcast audio in two public venues, a cinema and a museum.
A real-world Auracast™ experience
The participants mostly used a mix of BYOD Auracast™ enabled hearables, such as hearing aids, earbuds, and headphones. Those who did not have Auracast™ enabled hearables were offered dedicated Auracast™ receivers with wired headphones or neckloops. One of the visitors had a unique experience, using a loaned Auracast™ receiver connected to his current Cochlear Implant processor, he was able to clearly understand dialogue and reported that more than 80 percent of the audio was intelligible in a cinematic environment — an experience he described as highly enjoyable. He noted a clear improvement when listening via Auracast™ broadcast audio compared to using his processor microphone alone, with greater clarity and more consistent speech intelligibility. In fact, he found that listening to an Auracast™ broadcast directly, without blending in ambient microphone input, delivered the best overall experience.
Just as notably, he was able to use Auracast™ enabled audio alongside his processor microphone without any noticeable delay or disruption, a sharp contrast to prior experiences with hearing loops, where latency made audio difficult to follow. This points to the real-world impact of Auracast™ broadcast audio’s low-latency performance.
While some softer dialogue and scenes with overlapping sound effects were still more difficult to catch, the listener attributed this to the limitations of his current setup, using intermediary devices rather than direct, native support. He noted that accessing Auracast™ broadcast audio directly would likely further improve clarity, especially in more complex listening conditions.
What this experience shows
Clear improvement in real-world environments
Even in a cinema setting, one of the most challenging listening environments, the user was able to follow the vast majority of dialogue and enjoy the experience. This reflects how Auracast™ broadcast audio is already delivering meaningful, practical benefits.
A significant change over previous solutions
Compared to hearing loops, which introduced delays when combined with other inputs, Auracast™ broadcast audio provided a far more natural listening experience. The absence of noticeable latency is a critical advancement.
I hope each cochlear implant manufacturer will add Auracast™ support to their processors as soon as possible.
Designed for even more with native support
As native Auracast™ support becomes available in hearing aids and cochlear implants, listeners will be able to access these broadcasts directly, unlocking the full potential of clearer, more consistent sound.
