A multimodal auditory prosthesis. The prosthesis comprises a sound processing unit configured to process sound and to generate electrical signals representing different frequency components of the processed sound and a stimulation module communicably coupled to the sound processing unit, configured to stimulate the recipient to evoke a hearing percept of a range of the frequency components. The prosthesis also comprises an external stimulation module, configured to be positioned within an externally accessible portion of the recipient's first ear, comprising: a receiver unit to wirelessly receive the electrical signals representing the different frequency components, and a transducer that delivers acoustic or mechanical energy to the recipient's ear to evoke a hearing percept of a range of the frequency components.
