Temporal integration functions in hearing-impaired children.

Temporal integration was measured indirectly by obtaining threshold-duration functions with children (8 to 12 yr) who have sensorineural hearing impairment. Thresholds were obtained by an ascending technique at three frequencies (500, 2000, and 4000 Hz) and at three durations (25, 100, and 200 msec). The threshold-duration functions were flatter than those obtained previously on normal-hearing children, and steeper than those previously on hearing-impaired adults. Implications for clinical usage of brief-tone audiometry with children are discussed.
