Abstract: A sub-cranial vibratory stimulator that at least partially bypasses a recipient's skull bone and delivers vibration to fluid within a recipient's skull bone. The sub-cranial vibratory stimulator comprises an actuator that is configured to be implanted beneath a recipient's skull bone. The actuator transfers vibration to the fluid within the recipient's skull without first passing through the skull bone. The actuator is also substantially mechanically decoupled (isolated) from the recipient's skull bone.

Abstract: Methods, systems, and devices for determining control settings used by a hearing prosthesis to process a sound are disclosed. A first model output based on control settings is received by a computing device configured to fit the hearing prosthesis to a user. A difference between the first model output and a reference output based on normal human hearing at a target frequency is determined. If the difference between the first model output and the reference output at the target frequency is within a specification, the computing device sends a signal to the hearing prosthesis that includes information indicative of the control settings.
