Popis: OBJECTIVES: Previous research suggests that young children have significant difficulty recognizing speech in the presence of background noise as compared with older children and adults. However, limited research exists that examines the developmental effects of speech recognition in noise in separate age groups of young children, especially in a classroom setting. The lack of research may relate to the limited number of tests with multiple, equally intelligible lists in noise that are also appropriate for young children. As a result, the goals of the present study include investigating (1) effects of age and (2) benefits of spatial separation of speech and noise sources on the speech recognition in noise performance of young children with normal-hearing sensitivity. A secondary goal of the study was to establish the validity and reliability of the Phrases in Noise Test (PINT) for assessing the 50% correct speech-in-noise threshold of young children. DESIGN: The investigators used a two-way repeated measures design to examine the main effects of age and spatial separation. Sixty-eight children in separate groups of 3-, 4-, 5-, and 6-year-olds and 17 adults completed two speech-recognition conditions with (1) speech and noise from the same loudspeaker at 0-degree azimuth (S0/N0) and (2) speech and noise from separate loudspeakers at 0- and 180-degree azimuth (S0/N180). Recruiting sites included local preschools and school districts for children and a university for adults. RESULTS: The results of this investigation suggest that younger children (
