Auditory brainstem implant pitch discrimination and auditory outcome

We present a pitch discrimination test performed by five experienced adult auditory brainstem implant (ABI) users with neurofibromatosis type 2 (NF2). The ability to discriminate frequency/pitch from different channels on the may be an important factor in improving speech performance. was evaluated using triangle compared adjacent contacts and perception measured Swedish three-digit test. easy perform, all patients were able answer reliably, even though it cannot ruled out that used attributes other than differentiate between sounds. Due limited number of small variation results, no conclusive correlations could made regarding outcome. There tendency for poorer (discrimination tonotopically electrodes) at testing result results.
