SEVERAL indirect methods for determining auditory thresholds are in use at the present time. The two most widely used electrophysiologic methods are electrodermal (EDR) audiometry and electroencephalograph (EEG) audiometry. These procedures, while designed to alleviate the problem of requiring an overt response from a patient, present special problems such as the noxious conditioning stimuli as used with EDR procedures or the complex instrumentation needed for EEG audiometry. A method which would be easy to administer, free of the special difficulties noted above, and capable of determining thresholds with at least the validity of present indirect methods would be an important contribution to auditory testing. It is to this end that we studied the feasibility of using changes in respiration as a means of indirectly estimating threshold for pure tone stimuli.

Other investigators have also felt that measurement of respiratory changes in the presence of auditory stimuli might be a useful
