Speech perception as a function of electrical stimulation rate: Using the nucleus 24 cochlear implant system

Abstract

Objective: To investigate the effect of varying electrical stimulation rate on speech comprehension by cochlear implant users, while keeping the number of stimulated channels constant. Design: Three average rates of electrical stimulation, 250, 807, and 1615 pulses per second per channel (pps/ch), were compared using a speech processing strategy that employed an electrode selection technique similar to that used in the Spectral Maxima Sound Processor strategy (McDermott, McKay, and Vandati, 1992; McDermott and Vandati, Reference Note 1; McKay, McDermott, Vandati, and Clark, 1991) and the Spectral Peak strategy (Skinner et al., 1994; Whitford et al., 1995). Speech perception tests with five u..
