The percent of students reading below grade level from 1972 to 1976 was regressed on racial, socioeconomic, educational, and noise level variables for all elementary schools in Brooklyn and Queens, New York. Schools were assigned noise exposure scores based on Noise Exposure Forecast contours for New York City airports. The correlations between these noise scores and a variety of noise level metrics ranged from 0.74 to 0.97. The regression coefficients adjusted for confounding factors, indicated that an additional 3.6% of the students in the noisiest schools read at least 1 yr below grade level with 95% confidence limits from 1.5 to 5.8%. The dose-response relationship indicated that the percent reading below grade level increased as noise level increased.
对1972年至1976年纽约布鲁克林和皇后区所有小学中阅读水平低于年级平均水平的学生比例，就种族、社会经济、教育和噪音水平变量进行了回归分析。根据纽约市机场的噪音暴露预测等值线，为各学校分配了噪音暴露分数。这些噪音分数与各种噪音水平指标之间的相关性在0.74至0.97之间。经混杂因素调整后的回归系数表明，在噪音最大的学校中，另外有3.6%的学生阅读水平至少比年级平均水平低1年，95%置信区间为1.5%至5.8%。剂量反应关系表明，阅读水平低于年级平均水平的学生比例随着噪音水平的增加而上升。
