The Unitron Tandem is a niche product that is suitable if you have so little hearing in one ear that it's unusable from the point of having a standard hearing aid, and the other ear either has some degree of hearing loss or perhaps even no hearing loss at all.
Basically, the Tandem increases awareness of sound originating from the poor ear, relaying it wirelessly then to the better ear. Benefits include:
A greater ability to participate fully in conversations where otherwise hearing would have been difficult The ability to hear sounds originating from their poor ear side without turning the head Improved perception of the direction of sound sources.
To encompass all of the above this new hearing instrument allows a vastly improved, more balanced perception of hearing.
The device can be setup two ways. CROS or BiCROS system, depending on the type and level of hearing loss.
The Cros system would be used with a person that has good hearing in one ear and no hearing in the other. The transmitter picks up sound from the non-hearing side and wirelessly sends the audio to the receiver on the hearing side thus presenting it to the better ear.
The BiCros system is used in a situation where one ear has no hearing and the other has only some degree of hearing loss. The audio signal from the non-hearing ear is sent wirelessly to the better (although still impaired) ear, this is added to the audio picked up by the microphone on that side and both signals are added together and amplified to be audible in the better ear.
The hearing aid world is definately keeping in line with the fast rate that technology is improving in other sectors which is excellent to see especially from a hard of hearing perspective. At http://www.digitalhearingcare.org.uk we are proud to stock this pioneering device and others like it.
It will be interesting to see how the deaf community take to this new product as this device now opens up the hearing world to people who previously may not have been able to use a conventional hearing aid.
