The restoration of melody perception is a key remaining challenge in cochlear implants. A novel sound coding strategy is proposed that converts an input audio signal into time-varying electrically stimulating pulse trains. A sound is first split into several frequency sub-bands with a fixed filter bank or a dynamic filter bank tracking harmonics in sounds. Each sub-band signal is coherently downward shifted to a low-frequency base band. These resulting coherent envelope signals have Hermitian symmetric frequency spectrums and are thus real-valued. A peak detector or high-rate sampler of half-wave rectified coherent envelope signals in each sub-band further converts the coherent envelopes into rate-varying, interleaved pulse trains. Acoustic simulations of cochlear implants using this new technique with normal hearing listeners, showed significant improvement in melody recognition over the most common conventional stimulation approach used in cochlear implants.

A vestibular stimulation array is disclosed having one or more separate electrode arrays each operatively adapted for implantation in a semicircular canal of the vestibular system, wherein each separate electrode array is dimensioned and constructed so that so that residual vestibular function is preserved. In particular, the electrode arrays are dimensioned such that the membranous labyrinth is not substantially compressed. Furthermore, the electrode array has a stop portion to limit insertion of the electrode array into the semi-circular canal and is stiff enough to avoid damage to the anatomical structures.

A vestibular implant comprising a stimulation unit to generate electric stimuli and deliver to electrode arrays is disclosed. The stimulation unit generates electric stimuli in response to a user input or continuously generates electrical stimuli. The electrode arrays comprise electrodes and are adapted for placement within a semicircular canal of an ear. The electric stimuli is delivered from the stimulation unit to the electrode so that the electrodes apply electric stimuli. A predetermined electric stimulus is applied to restore spontaneous vestibular activity during a Meniere's attack. A continuous, unmodulated electric stimulus is applied to suppress the symptoms of unilateral loss of vestibular function. Additionally, the electrodes record electrically evoked compound action potentials (eCAP). An appropriate location for the placement of the electrode array is determined based on the recorded eCAP.
