title: Frequency resolution after successful surgery in congenital ear anomalies.
abstract: Frequency resolution was studied in patients with a unilateral congenital ear defect (atresia), who were successfully operated on. Psychophysical tuning curve (PTCs) were obtained. A comparison of the shapes of the PTCs revealed that the average curve for all the patients was much alike for the operated and non-operated (normal) ear: broad tuning curves, as reported from animal studies, were not found. After appropriate corrections were made for the small remaining air-bone gaps, as seen in all patients, the PTCs of all the operated ears lay reasonably well within the 2 S.D. range of the average PTC obtained in subjects with normal hearing.
