“I don’t need a microphone.” But yes, you do

Picture of an ear with sound wavesThere 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 device 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 object. 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.

Hearing Loops are not obsolete technology

One such technology is hearing loops. The basic technology remains the same but improvements are being made over time. Thinking that modern hearing aids have improved so much that people don’t need augmentation in meeting venues is a bit like saying wheelchairs have improved so much we don’t need ramps.

Andrew Stewart at ClearaSound nicely addresses all the myths and misconceptions about hearing augmentation systems and says that the hearing loop is still the most efficient and effective for users, and the most convenient for venue managers. Other systems are not popular because of additional equipment that needs to be worn or used which singles users out from the crowd. Andrew also provides the BCA references at the end of the newsletter.

It is noteworthy that recent research is showing that one in three older people do not use their hearing aids – it will be worth finding out why because it is one of the key factors in social isolation.
