• The respiration of ten adults with normal hearing was monitored to determine how well changes in respiration could be detected after auditory stimulation. Three judges used two methods of response scoring. The first was without knowledge of signal presentation, and the second was with knowledge of signal presentation. Judges detected the presence of respiratory responses not only during signal presentations (hits) but also during silent intervals (false alarms). Hits and false alarms co-varied in a manner predicted by the theory of signal detectability. A low false alarm rate could be purchased only at the expense of a low hit rate. The implications of this finding for the clinical efficacy of respiration audiometry are considered.
