1. A method of providing neural stimulation to a recipient, comprising:
- receiving an acoustical signal;
determining a set of stimulation signals based on the received acoustical signal, comprising;
determining a first stimulation signal based on a perceptual power of the first stimulation signal; and
determining at least one other stimulation signal based on a perceptual power of the at least one other stimulation signal using information indicative of a masking effect of the first stimulation signal on the at least one other stimulation signal; and
applying stimuli to a recipient using the determined stimulation signals.

Abstract
An embodiment of the present invention takes masking effects into consideration when determining stimulation signals for neural stimulation. These masking effects may be modeled using user-specific models determined by taking measurements for an implant system of an implant recipient. Or, the model may correspond to a group of individuals sharing a common characteristic or the population as a whole. These models may be, for example, psycho-physical models.
