Single sided deafness (SSD) is the loss of hearing in one side. It is a common problem that can often be caused by viral infections, Meniere's disease or head and ear injuries. Fortunately, there are specific products like the CROS (Contralateral Routing of Signals) system that can help reduce SSD's impact on your life.
People with SSD often have problems in locating where sounds are coming from. They may also experience probems with understanding speech in noisy environments and can struggle to hear people talking on one side in particular.
There are some products available for SSD which allow you to hear from both sides again with clarity. The CROS system picks up sounds and voices from the bad ear and wirelessly sends them over to the good ear.
