The Unitron Tandem 4 is the lower level of technology in this range. This type of hearing aid would be suitable for someone who has a complete loss of hearing in one ear.
In 2011 Unitron launched their Tandem range which is designed for people who only have hearing in one of their ears. Available as the CROS or BICROS system, it is suitable whether you have perfect hearing in your good ear or if you have a hearing loss in that ear as well. It is available in two levels of technology, the Tandem 16 or Tandem 4, of which the 4 is the lower level. CROS stands for Contralateral Routing Of Signal and refers to the way the sound is transmitted from one ear to the other.
CROS – For those who do not have a hearing loss in their good ear.
This system works by placing a transmitter in your non-hearing ear to pick up the sound. This then wirelessly sends the sounds to a device in your normal hearing ear while maintaining a natural sound.
BICROS – For those who also suffer from hearing loss in their hearing ear.
If you also have a hearing loss in your other ear, the BICROS system will work in exactly the same way as the CROS but the receiving hearing aid will also manage the hearing loss in this ear.
