Summary on Grant Application Form |
|
Sound waveforms that repeat over time (such as vowel sounds or musical tones) are often associated with a distinct pitch that corresponds to the repetition rate or fundamental frequency (FO) of the tone. Such tones are composed of a series of equally spaced sinusoidal harmonics. The lower harmonics (< number 10) are separated out by the spectral analysis of the peripheral auditory system and are said to be Dresolved0, whereas the higher harmonics are unresolved. Modern theories of pitch perception usually assume that a single auditory mechanism is used to derive the pitch of both groups of harmonics, however recent evidence suggests that this may not be the case. The present experiments will use psychophysical procedures to determine whether the single mechanism account is correct. In addition, the research will determine how the resolved harmonics (which are dominant in pitch perception) are combined over time and frequency to generate a single pitch.
