Pitch perception is important not only for the enjoyment of music and for the perception of prosody in speech, but also for our ability to process one sound, such as a voice, in the presence of competing sounds. Poor pitch perception, and the resulting difficulties when listening in noisy situations, are a common source of disability in deaf patients whose hearing has been restored by a cochlear implant (CI). I will summarise some experiments that address the following questions;
The experiments involve a combination of NH psychoacoustics, investigation of an illusory percept, CI psychophysics, electrophysiological recordings, and the results of a double-blind placebo-controlled drug trial. I will also briefly describe other experiments from our lab that aim to improve hearing by CI listeners.
