Summary

This clinical study aims to investigate speech performance in quiet with an OTE Sound Processor with modified firmware compared with the commercially available CP1150. The study also investigates CP1110 and CP1150 with Forward Focus.

Detailed description

This study will build on the evidence previously collected on OTE and BTE Sound Processors and will support the design goals for access to the same sound processing algorithms across future OTE and BTE variants, including evidence required on the automation of FF and future implant compatibility.

Conditions

• Hearing Impairment, Sensorineural

Interventions
