There are three types of hearing augmentation systems – but which one to use? The system preferred by most users is a “hearing loop”. It is connected to the sound system in a meeting room or auditorium. People wearing a hearing aid with a telecoil, have the sound sent directly to the device. It screens out all the background noise and gives definition to the speech. However, a microphone must be used all the time. So no more “I’ve got a loud voice, I don’t need a microphone” because it won’t be transmitted.
Hearing Connections website gives an explanation of this system, FM and Infra-red systems. A system with an ambient microphone that picks up all the sound in the room amplifies all the sounds – so background noise is included with the speech. It can defeat the purpose. Also, the system should be turned on automatically – no-one should need to ask for it – that’s the point. Building designers, owners and managers have a legal obligation to incorporate the needs of people who are deaf or hard of hearing.
Editor’s comment: I’ve been given lots of different reasons why the hearing system isn’t working. I’ve been told that permission is needed from security to turn it on, as well as being told it can’t be switched on because people outside the room might hear confidential information. Clearly, having the system installed and connected is one thing, and training people about its use and purpose is another. Newer Bluetooth and wireless technologies are looking positive for improved experiences in the future.
