Signal processing for hearing prostheses

A device comprising:

• a sound input element configured to receive a sound signal, and to convert the sound signal into an electrical signal;
• a sound processor configured to generate a stimulation signal based on the electrical signal, and to apply frequency shifting on the stimulation signal to generate a frequency shifted stimulation signal, wherein the frequency shifting depends on one or more of a decibel level of the received sound signal, a hearing loss level associated with generating the stimulation signal, attenuation of an output based on the frequency shifted stimulation signal, or operating in a single sided mode or a bilateral mode;
• and
• an actuator configured to generate the output based on the frequency shifted stimulation signal, wherein the output is configured to be perceived as sound.

An article of manufacture including a non-transitory computer readable medium with instructions stored thereon, the instructions comprising:

• instructions for generating a stimulation signal from a sound signal;
• instructions for applying frequency shifting to the stimulation signal to generate a frequency shifted stimulation signal, wherein the frequency shifting depends on one or more of a decibel level of the sound signal, a hearing loss level associated with generating the stimulation signal, attenuation of an output based on the frequency shifted stimulation signal, or operating a hearing prosthesis in a single sided mode or a bilateral mode;
• and
• instructions for providing the frequency shifted stimulation signal to an actuator of the hearing prosthesis, wherein the actuator is configured to generate an output based on the frequency shifted stimulation signal, and wherein the output is configured to perceived as sound.
