我们研究了40名幼儿（5至8岁）在现实生活中的教室噪音的背景下听时理解语音（单音节，spondees，扬抑音和三音节）的能力。当噪音达到许多教室的水平时，所有的孩子都很难理解语言（即，65 dBA）。然而，在中等（-6 dB SNR）水平，幼儿园和1年级的儿童有更多的困难比年龄较大的儿童。所有儿童在安静的环境中表现良好，结果与先前研究报告的结果相当或略好于先前研究报告的结果，这表明该任务适合年龄且易于理解。这些结果表明，学校系统中年龄最小的儿童，其教室也往往是最嘈杂的，最容易受到噪音的影响。
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 the noisiest, are the most susceptible to the effects of noise.
