How do I fit Zen for a patient with unilateral tinnitus?
Even when unilateral tinnitus is reported, a binaural Zen fitting is recommended. While tinnitus is an auditory perception that maybe localized to the right ear, left ear, both ears or middle of the head, the generators of tinnitus lie centrally in the brain.  Monaural fittings may be ineffective as it may draw attention to tinnitus in the non-fitted ear. Monaural fitting is only appropriate when one ear has no useable hearing.
