A prosthetic system, comprising a first sub-system configured to evoke a hearing percept based on a first principle of operation, and a second sub-system configured to evoke a hearing percept based on at least one of the first principle of operation or a second principle of operation different from the first principle of operation, wherein the first and second sub-systems are configured to independently process respective inputs indicative of an ambient sound to harmonize an estimated recipient perception of magnitude of a property of the respective evoked hearing percepts.

Hearing percept parameter adjustment strategy for a hearing prosthesis

Embodiments generally relate to a method of assessing the hearing of a patient using functional near-infrared spectroscopy (fNIRS). The method comprises receiving at least one response signal from an optode placed on a scalp of the patient, the response signal comprising fNIRS data generated by the optode and relating to an aural stimulation received by the patient; comparing at least one parameter of the at least one response signal to a predetermined parameter value; and determining an auditory response of a patient based on the at least one parameter of the at least one response signal.

Hearing assessment system and method

An auditory prosthesis device for selectively stimulating electrodes within an auditory prosthesis electrode array, comprising a transducer () for converting a complex acoustic sound into an electrical signal; signal processing means () responsive to an electrical signal and generating a temporal pattern of stimulation pulses to selected electrodes within the electrode array, the stimulation pulses being applied to each electrode at an electrode stimulation rate; feature extraction means () for deriving an estimate of at least one fundamental frequency of the electrical signal; and stimulation pulse adjustment means () for adjusting the stimulation pulses in accordance with the estimated fundamental frequency.
