N2 - Cochlear Implant (CI) listeners can do well when attending to speech inquiet, yet challenging listening situations are more problematic. Previousstudies have shown that fluctuations in the noise do not yield better speechrecognition scores for CI listeners as they can do for normal hearing (NH)listeners. The aim of this experiment was to investigate the ability ofsimulated CI listeners in a prosodic task, where F0 Just NoticeableDifferences (JND) were measured in modulated and stationary backgroundnoise.A nonsense sentence was created from a recording with durations andoverall contour derived from non-scripted Danish speech. The F0 temporalmidpoint of the initial syllable was varied stepwise in semitones.Competing signals of modulated white noise and speech shaped noise at 0dB and 12 dB SNR, were added to the tokens prior to 8-channel noiseexcitedvocoder processing. Stimuli were presented diotically to 8 NHlisteners in a 2AFC task. A question/statement identification experimentwas also performed. Results from the JND experiment indicate a significantnoise effect for the modulated noise condition at the lower SNR.
