Abstract
We examined the ability of 40 young children (aged five to eight) to understand speech (monosyllables, spondees, trochees, and trisyllables) when listening in a background of real-life classroom noise. All children had some difficulty understanding speech when the noise was at levels found in many classrooms (i.e., 65 dBA). However, at an intermediate (-6 dB SNR) level, kindergarten and grade 1 children had much more difficulty than did older children. All children performed well in quiet, with results being comparable to or slightly better than those reported in previous studies, suggesting that the task was age appropriate and well understood. These results suggest that the youngest children in the school system, whose classrooms also tend to be among he noisiest, are the most susceptible to the effects of noise. Evaluamos la capacidad de 40 niños (edades de cinco a ocho) para entender el lenguaje (monosilábicos, espondaicos, trocaicos y trisilábicos) al escucharlo en medio de un auténtico ruido de fondo de aula de clase. Todos los niños tuvieron alguna dificultad para entender el lenguaje cuando el ruido estuvo a los niveles hallados en muchas aulas de clase (p.e., 65 dBA). Sin embargo, a un nivel intermedio (-6 dBA), los niños de jardín de infantes y de primer grado tuvieron más dificultad que los niños mayores. Todos los niños funcionaron bien en silencio, con resultados comparables o hasta ligeramente superiores a los reportados en estudios previos, sugiriendo que la tarea era bien entendida y apropiada para la edad. Estos resultados sugieren que los niños más jóvenes dentro del sistema escolar, cuyas aulas de clase suelen ser las más ruidosas, son los más susceptibles a los efectos del ruido.Keywords
