英文摘要
The overall goal of this research is to develop a better understanding of
the mechanisms that underlie intensity processing in normal and impaired
ears. A major portion of this proposal examines the relation between
loudness growth and the ability to identify small increments in level,
which is known as intensity resolution. Of particular interest are
conditions that are known or ar likely to modify intensity resolution and
loudness, such as adding tones to a complex tone or the detection of a
brief tone during the onset oa a broadband noise (i.e., overshoot).
Another phase of this research examines the relation between intensity
resolution and loudness in individuals with acoustic tumors to test the
hypothesis that adaptation is responsible for the abnormal intensity
processing in these listeners. Subjects with acoustic tumors will enable
a critical test of excitation-pattern models invoked typically for modeling
intensity processing in normal and impaired hearing. A third series of
experiments examines the role of cognitive factors (such as memory and
context) on loudness and intensity resolution. Experiments with varied
stimulus contexts (e.g., forward masking with cues) will provide data more
relevant to everyday listening conditions than those from fixed stimulus
contexts, but both fixed and variable contexts need to be studied to
separate cognitive mechanisms from sensory ones. This proposed research
will provide critical tests of current models for relating loudness and
intensity resolution and should provide insights into the mechanisms
underlying these phenomena. The data from these experiments also should
prove useful in the design and fitting of hering prostheses, such as in the
evaluation of channel independence in cochlear implants.
