Provision of stimulus components having variable perceptability to stimulating device recipient
First Claim
1. A method comprising:
- receiving a user-specified current level; and
applying to a stimulation channel of the cochlear implant a stimulus signal comprising a substantially imperceptible component based on the user-specified current level and a perceivable component having the user-specified current level.

Abstract
The automatic measurement of evoked compound action potential (ECAP) thresholds of the auditory nerve; that is, a neural response, concurrently with the performance of psychophysics measurements of a prosthetic hearing implant recipient. During the fitting process, a stimulus signal comprising two components is applied to each stimulation channel. One signal component is configured to elicit an ECAP neural response, referred to herein as a neural response signal component. The other component is configured to elicit a response to a psychophysics stimulation, referred to herein as a psychophysics signal component. Indications of the psychophysics measurement and the concurrently obtained neural response measurements are provided to the user. For the psychophysics measurement, this includes the selected characteristics of the psychophysics signal component since the results of the applied stimulation is a recipient behavioral or auditory response.

- 10. A fitting system configured to receive a user-specified current level, and to provide an instruction to a cochlear implant to cause the cochlear implant to apply to a stimulation channel of a cochlear implant a first stimulus signal comprising a substantially imperceptible component based on the user-specified current level, and a perceivable component having the user-specified current level.
- 16. A fitting system configured to receive a user-specified current level, and to provide an instruction to a cochlear implant to cause the cochlear implant to apply to a stimulation channel of a cochlear implant a stimulus signal comprising a substantially imperceptible component based on the user-specified current level, and a perceivable component having the user-specified current level, wherein each of the substantially imperceptible component and the perceivable component are configured for determination of a common dynamic range parameter for the cochlear implant.
