We review various kinds of masking that affect sensitivity to auditory stimulation and models that attempt to explain these phenomena. We then discuss intensity and loudness perception, including a review of models of these processes. Initial one-page proposal for final project due today. The complex circuitry within the Dorsal Cochlear Nucleus, or DCN, will be studied in some detail, both anatomically and physiologically. Models of DCN will be explored as well.
Today is the first of two in-class exams.
This week, we look at the perception of the pitch and timbre. The perception of sound timbre is then considered. A spectral network model of pitch perception. The physiology the Superior Olivary Complex is discussed, including their specialization, and how it relates to spatial hearing. The next stage of auditory processing occurs in inferior and superior colliculi.
