Abstract
Aspects are generally directed to techniques for determining weights for stimulation channels of a stimulating hearing prosthesis. The determined weights are used to provide stimulation to a recipient of the stimulating hearing prosthesis.
Claims20
A method comprising:
- determining a transimpendance matrix for a plurality of electrodes that are part of a hearing prosthesis;
- performing a matrix inversion of the transimpedance matrix to obtain a transadmittance matrix for the plurality of electrodes;
- generating an adjusted transimpedance matrix comprised of the transimpedance matrix having a diagonal that is modified based on positive off-diagonal values of the transadmittance matrix;
- calculating, using the adjusted transimpedance matrix, corresponding weights for the plurality of electrodes for a stimulation channel;
- and
- providing the calculated weights to the hearing prosthesis;
- and
- using the calculated weights to deliver stimulation to a recipient of the hearing prosthesis via one or more of the plurality of electrodes.
