CROS
Good ear is normal or near-normal. The transmitter only copies sound across. You still hear with one cochlea — the device does not repair the dead side.
For people who hear on one side and little or nothing on the other. A small transmitter on the poor ear sends sound to a hearing aid on the good ear, so you are not always “deaf to the left of the table”.
Good ear is normal or near-normal. The transmitter only copies sound across. You still hear with one cochlea — the device does not repair the dead side.
The better ear also needs help. That side wears a hearing aid; the poor side wears the transmitter. Common after infection, surgery, sudden loss or Ménière’s.
CROS is not a cochlear implant and not a bone-anchored aid. You will not localise sound like two healthy ears. Restaurants improve for many people; they do not become easy. Sudden one-sided loss still needs GP / 111 / A&E first — we do not start a CROS trial in an emergency.
NHS may offer CROS in some audiology departments. We will say if that is the sensible route. Private CROS/BiCROS is quoted after the test; brands depend on what we can order (often Phonak or Signia systems).
A trial, in writing, on selected systems. Same clinic, same clinician. Terms.
