项目摘要
The proposed experiments test the feasibility of using a particular class
of electrical responses extracted from the brainwaves as a non-behavioral
method for measuring hearing at the audiometric frequencies. The High
Rates Response (HRR) with which the research is concerned is recorded
through scalp electrodes when brief tonebursts are presented at high rates
(15-60 per sec.) through an earphone; it is closely related to the
so-called middle latency (8 to 80 msec.) auditory evoked potentials and has
other names (e.g., 40 Hz ERP, MLR40, SMLR, etc.). Previous research has
shown that the HRR predicts hearing thresholds less accurately in
uncooperative or sleeping children than in quiet, wide-awake adults. We
believe this lack of accuracy is due in part at least to current use of a
single measure only--HRR amplitude at one stimulus rate--in the data
analysis. Our research proposes to replace this with a single response
statistic developed out of the multiple measures available after the
Fourier transformation of the HRR, an approach that should theoretically
improve both the accuracy of HRR measurements and the detectability of
threshold responses. If successful, the research will first of all
describe the design requirements for a practical electric response
audiometer that will use the HRR to make threshold estimates quickly,
accurately and automatically. Second, it will provide a new, efficient
measure of brain responses to above-threshold stimuli that may find useful
neurological applications in sleep studies and the diagnosis of abnormal
brain states.
