Over the years we have seen many different methods of assistive listening systems in public spaces, these vary in technology and have seen some more popular than others, but now there is a new player in town.
The Most Popular Option
T-Coil or Telecoils work in two parts, there is an antenna in the hearing aid, which picks up a signal from a magnetic coil which is either installed in the space (in a theatre), furnishings (in a coffee shop, or airport gate) or in a portable device which can be placed on a desk when required. These coils are connected to a microphone or audio source. These devices can be found in a wide variety of locations and are supported by a large number of devices. Simply switching the personal device to the T mode, will enable the t-coil and allow the person to receive the signal.
As we can see here, there are a wide range of locations that we can find T-Coil in public. The issue with T-Coil however, is that the signal can be distorted, or have a buzzing with it, due to the nature of the technology. This leads to having to listen in noise, which is sometimes less than ideal for those with hearing loss.
However, the Future is Here
“Auracast could be used in an airport to allow people to listen to announcements at the gate, or talk to a gate agent”
Bluetooth SIG recently announced the introduction of Bluetooth Auracast. Auracast is designed to transmit audio over bluetooth using Bluetooth LE which is supported on a wide range of devices, including phones, ear buds, hearing aids, cochlear implants (Cochlear announced support for the N8) and more. With the introduction of Auracast, when in an area covered by an Auracast transmitter the user will be able to choose a channel of audio and directly stream this to their chose device.
Auracast could be used in an airport to allow people to listen to announcements at the gate, or talk to a gate agent. It could be used at a sporting event to allow people to choose the language of the commentary, or it could be used at the theatre to allow the choice of described audio. The uses go beyond those with hearing loss, and could provide better access to the TV at the gym, to watching a movie at a drive in theatre, and to provide sound in a very noisy or very quiet space.
Streaming crystal clear audio over a low powered platform which is already widely supported by many devices, understood by people, and manufacturers, and easy to implement seems like a no brainer. The best part here however, is that this technology is accessible by everyone, not just those with hearing devices, and this is what makes Auracast truly stand out. The fact that what is essential for some is beneficial for all.
