Effects of Stimulus Type on 16-kHz Detection Thresholds.

Objectives: Audiometric testing typically does not include frequencies above 8 kHz. However, recent research suggests that extended high-frequency (EHF) sensitivity could affect hearing in natural communication environments. Clinical assessment of hearing often employs pure tones and frequency-modulated (FM) tones interchangeably regardless of frequency.

Speech-in-Speech Recognition and Spatially Selective Attention in Children and Adults.

Purpose Knowing target location can improve adults' speech-in-speech recognition in complex auditory environments, but it is unknown whether young children listen selectively in space. This study evaluated masked word recognition with and without a pretrial cue to location to characterize the influence of listener age and masker type on the benefit of spatial cues. Method Participants were children (5-13 years of age) and adults with normal hearing.

Binaural Frequency Modulation Detection in School-Age Children, Young Adults, and Older Adults: Effects of Interaural Modulator Phase.

Objectives: The purpose of this study was to measure low-rate binaural frequency modulation (FM) detection across the lifespan as a gauge of temporal fine structure processing. Children and older adults were expected to perform more poorly than young adults but for different reasons.

Design: Detection of 2-Hz FM carried by a 500-Hz pure tone was measured for modulators that were either in-phase or out-of-phase across ears.
