Webassessing is adaptive bearnforming. The Griffiths-Jim beam forming system, used with hearing aids, has been applied to the cochlear implant6 (also van Hoesel et al, this suppl, section 12). The bearnforming system is illustrated in Fig 8. This shows that for the bearnformer the signal in the right ear will be 5 + N 1 and the left ear 5 + N2.
