Determination of the Feasibility of Using Pupillary Responses as a Measurement of Auditory Perception.
Abstract
An experiment was performed to measure the pupillary response to a series of pure tone audio stimuli presented at the threshold level of hearing. The total number of subjects tested was seven (1 female, 6 males). Each was placed in an audiometric anechoic chamber and subjected to pure tones at five frequency levels within the normal speech range. Intensity levels were just below, in the vicinity of, and above the subject's hearing threshold while the pupil activity was being continuously monitored and recorded by a Space Sciences T.V. Pupillometer. The result was observation of no detectable pupil response due to threshold auditory stimulation in any subject for all the frequencies tested. (Author)
